Granddaddy System!Expert required! Alpine?Fosgate?Or Non-Brand?

Status
Not open for further replies.
hello all, i would like some expert advice as iam looking to get a grand-daddy system.

I have looked at three types, Alpine, Rockford Fosgate and a non-brand make which seems to beat the others by technical aspect. Iam looking to get two strong subs, and a good amp to compliment it.

I went to a car audio show room and i was looking at some subwoofer and amp package deals and i really want to get the grand-daddy of all subwoofers but come with the superiority, so does the price. Here are the subs and amps i looked at, i have also provided the links and prices so you can look at the technical aspect as i do not understand much. I only know the key points about the subs which is, high RMS, low frequency and high sensitivity. I know nothing about the amps.

Iam looking to get two 12" rather than one 15".

Sub - Alpine SWR-1222D 12" - £119.99 http://www.alpine-europe.com/conten..._12--30cm-Subwoofer-2Ohm+2Ohm---4Ohm+4Ohm.htm

Amp - Alpine MRD-M1005 - £299.99 http://www.alpine-europe.com/conten...d-with-comprehensive-computerised-control.htm

From what i could understand the Alpine sub has a 500W RMS and a Frequency response of 24hz no info about the sensitivity.

I also looked at the Rockford Fostgate who are seem to be a bit more pricey but are much better quality wise. The two i looked at was,

Sub - P312 12" £179 http://www.rockfordfosgate.com/prod...temKey=10065584&CategoryDesc=Punch Subwoofers

Amp - T10001BD - £549.99 (very pricey!) http://www.rockfordfosgate.com/prod...temKey=10063516&CategoryDesc=Power Amplifiers

From what i could gather, the Rockford Fostgate offers the same RMS of 500W, its sensitivity is 87 (which i think should be higher for that price) and the Frequency is 25hz. Thats lower quality than the Alpine but more pricey...but there must be more technical aspects, tweaks and perks which i do not have the knowledge to understand the value those specialties.

These prices have been offered to me at near enough trade price so thats one good thing about it or so i was told.

I was also looking at some deals on eBay and i came across, what looks to be the very very reasonable package deals.

If you go to http://stores.ebay.co.uk/The-Loudest_Bundle-Deals and look at Deal 4.

This looks like a mega package deal that i would go for. Two 4000W 12" subs, 8000W amp, enclosure and wiring kit for poo money that i would of paid over a grand for the other kits. The subs offer 1500RMS, frequency is 21hz and the sensitivity is 90db! The RMS alone on this is 3 times as big compared to the other leading brands. Again i do not know anything about the amp so i cant comment on it.

I also went to their official website and the same amp they are offering on eBay is £1495 on their website! This also sounds insane so the links to the subs and amps are (if you could please take a look)

non-brand sub - http://www.theloudest.co.uk/index.php?id=view_product&product_id=85

and non-brand amp - http://www.theloudest.co.uk/index.php?id=view_product&product_id=91

they also offer 6.5" which i was thinking of changing anyway cos the front side of the card is farting.

the link to that is http://www.theloudest.co.uk/index.php?id=view_product&product_id=82

OOoooo, take deep breath. lol

If you could please take a look at all the links and give some advice with great expertise i would be the happiest man in the world! As far as i am concerned, the non-brand (loudest.com )are far more superioir and cheaper compared to the other deals i have been offered.

From the little technical knowledge i know, the non-brand subs look much more powerful. They give full specification on their subs and amps so again, some expertise would be much appriciated.

If there is anything suggested, or even mix and matching the components please do so.

I would be very very happy if someone was to give some detailed analysis of the subs and amps i have written.

If by now you have read upto here, thanks for reading!

Looking forward to any suggestion and ideas.

Alright, well first off, I hate to break it to you but those are nowhere near "granddaddy" systems. The Alpine Type-R is pretty low on the totem pole, as is the Fosgate P3.

As for specs, you're really looking at the wrong things. You're looking at the specs that markeneers count on, the ones they can "fudge" to make their product look better than it really is. The rated frequency response should be completely thrown out right at the beginning, don't even bother taking a peak at it when looking at subwoofers, it's completely meaningless. Efficiency doesn't really mean that much, partially because most of the sleezy companies will either measure it in a way that inflates their numbers (2.83V/1m, in-car, etc) and not tell you, or just flat out lie. Besides, the actual efficiency depends on the enclosure you use. The rated power is more important, but you still shouldn't choose one speaker over another based on that. There are subs that can get very loud, sound very good, and do it on very little power. They normally have a low power handling, so if that's all you look at you would have no idea how capable it really is. Besides, there are companies like that last one who slap huge power numbers all over their products, and if you actually tried to send them that much power they would go up in a ball of flames.

If you want to know how loud the sub will get in a sealed box before distorting too heavily then look at the Xmax and Sd, if you're only looking at 12s then the Sd should be pretty similar for all of them, so the Xmax will be the one to look at. If you want to know how low the sub will go for a given alignment, don't look at the rated frequency response, look at the Fs.

What kind of enclosure are you looking at using, ported or sealed? Some subs are built more for one application or the other, you should look at the Qts and the EBP (Fs/Qes) to determine which it was designed for.

All that said, the Alpine Type-R is a pretty decent sounding sub that can get reasonably loud, at least as far as inexpensive subs go. The Fosgate P3 really isn't impressive, I wouldn't give it too hard of a look. That other brand is really sketchy, I'm not too sure about them. Their specs match up with each other (2 ohm stereo power ratings = 4ohm bridged power rating, it should be like this but some companies like to break the laws of physics when they rate their amps) which is a good sign, but they're one of those companies that gives the products a peak power rating much higher than it should be, and then slaps that number all over the place, that's a sign of trouble. They also rate the amplifier power at a higher than normal THD, giving themselves higher power numbers than they would get with a more widely used rating. Their component set doesn't look too impressive either.

I'd love to recommend other stuff, but I don't know what kind of price range you're looking in, what you listen to, or what kind of sound you're going for: spl (getting loud), sq (sounding good), or a mix (some spl, some sq, can't have all of both unless you spend a lot of money so you need to decide which one matters more to you).
 
Thanx!

Wow, first of all i would like to thank for such a great and detailed reply and i now much clearer understanding.

I have a VW Passat so a huge boot! Budget wise iam looking to get £1100 but can push to £1400. Thats about between $1950 and $2500.

Ported or sealed i am not that fussed about. I wouldnt want my car rattled and i would also like to take out the subs when i am going to use the boot, so i guess i would like it sealed with that metal sticky stuff! As for Qts and EBP are concerned, i really wouldnt have a clue where to start looking so some advice would be much appriciated.

I am looking to get super bass and excellent clarity and i listen to r & b, hip-hop but also the odd soul fusion and drum and bass. I guess thats more punch than deep bass. So overall a crisp SPL sound quality.

I also came across http://www.edesignaudio.com/ which looked pretty decent but again, i never heard or dont know much abou them, I hope this helps, looking forward to your reply!

Does that budget include a headunit, components, amp for the components, etc as well as the sub and amp, or is it just for the sub and amp?

It does sound like you would be better suited with a sealed setup, though it sounds like you'll need a lot of displacement. 2 good 12s should fit the bill well. Most subs can be sealed, the problem normally comes when trying to port them. For a sealed setup, look for a Qts between .4 and .6 or so (slightly out of the range is fine), and an EBP (Fs/Qes) below 90. Most subs should fit these ranges except for some that are built more for spl use only (such as the RE MT, many of the DD and AQ subs, etc).

Elemental Designs is kind of a weird company, it's hard to explain. They've had some terrible reliability problems over the years, plus they completely overhaul their lineup on a regular basis. In the last few years they've gone through 3 buildhouses and something like 15 different subwoofer lines, all but 2 are now discontinued for one reason or another. Sure they come with a 3 year warranty, but don't expect to get the same sub again if one of yours happens to break. That's alright if you're using a single sub, but if you've got 2 and one of them breaks, you don't want to replace it with something completely different.

That said, their new lines seem to be holding up, at least better than their past lines did. I've got one of their older subs, the e12a, and it worked well. It had some major problems with low end extension in the recommended sealed box, and it was pretty peaky in the recommended ported box (most subs will be peaky in a ported box in the car due to cabin gain), but it held up. I moved on to another company mainly because the owner of eD is...well...let's just say I moved to another company because of the owner of eD.

People do seem to be happy with their new subs and amps, it's up to you if you want to go with them.
 
i forgot to mention i have JVC KD-AVX1 head unit which has, RMS Power Output 20, Peak Output 50 Watts and loads of outputs at the back!

dude, you really sound like you know what you talking about. could you recommend a good package for my budget. thank you and looking forward to your reply!

Well it really depends on your budget. I wish I could recommend Adire Audio, as they've supplied nothing but absolutely amazing products to me to date. Right now they're in between buildhouses though, they're still working on building up a stock before they release their new products to the public.

I saw your post on ECA, so I know you're a member over there, that's probably one of the best car audio forums on the web, so it's good that you signed up over there instead of one of the bad ones. I'm a member on there too, I've been watching the replies and most seem acceptable (by my standards at least). Many of the people with low post counts are newbies to the industry who don't really know what they're talking about, so take their comments with a grain of salt, but there are many people who really know what they're talking about, much more so than I, I have to admit. There's a lot to learn over there, so keep an open mind.

Anyway, your headunit is enough to power some cheap coaxs, but not some nice components. It'd definitely be worth investing in a front stage amp, if you can afford it. I assume your quoted budget includes everything, so I'll try to stay under $2500 total.

So, where to begin...you have plenty of choices, hundreds even. I'll try to give you the most objective point of view that I can, that's the best I can promise.

If you're after SQ and output then Image Dynamics is a pretty good choice. People rave about the sound quality of the IDQ and IDMAX subwoofers, I don't think I've ever read a negative review of either. I've also spoken with the spokesman for ID on multiple occasions and have not been disappointed (as I have with eD) with what he's had to say. If I were in your shoes, I think I would probably go with a pair of IDQ or IDMAX 12s and a set of the Chameleons. As far as amps go, as long as you go with a respectable brand you should get a respectable result. There really isn't much difference as far as amps go, as long as you go with something decent IMO. The cheapest respectable brands I know of right now are the Profile amps on www.millionbuy.com and the Phoenix Gold Octane amps on ebay, either of which should serve you adequately.

Alright, time for the part you actually care about. If I were in your shoes, this is the setup I would go with:
ID Chameleon 6XS62 - $180
Phoenix Gold x200.2 - $200
2x ID IDMAX12 D4 - $700
2x Phoenix Gold x1200.1 - $500

Total - $1580
Plus you have you add in deadening and wiring, for deadening I would go with secondskin, at least 50sqft to cover the doors and some of the trunk. For the wiring I would go with www.darvex.com, they sell quality products at reasonable prices which should cover the subwoofer setup. Not sure what else there is, I have experience with most of the brands that will be thrown around on the forums out there, and not too much has impressed me with the exception of USAA, NASA, etc.
 
I wish I could edit, I just noticed a typo (or two) in my last post

The ID Chameleon 6XS6 4 would be a better choice with that amp, and they're $350, not $180, I wasn't thinking clearly. The last sentence also makes no sense at all, I think a gremlin popped into my head and made me start babbling incoherently, so just disregard it.

Anyway, ID is a good choice if those mids will fit in your vehicle (they're pretty deep), and those PG Xenon amps are getting a lot of praise. There are other choices of course, several companies introduced some interesting products at this year's CES, so if you wait for a couple of months you might start to see them on the shelves. I'm sure other people will have some good recommendations too.
 
2x Phoenix Gold x1200.1 - $500



Where ya gettin them for $250 a pop? Ihave a PG X1200.1 and I love it! This amp is WELL built as for mine is on my bench being repaired due to a water mishap (no comment). I ordered a Kicker sx1250.1 as a backup, no fun being bassless. Anyone have anyexperience with this Kicker amp? Polo..🙂

Looks like you found another typo, that's not supposed to be 2x, just 1

Man, I really need to cut out those late night posts...
 
ok guys, iam going to get two 12inch Diamond TDX 12D4. Iam contemplating whether to get two 15inches and if that is worth the mojor difference. Anyone with any experience?

Also, if you could, recommend me some amps to go either with the 12inch or the 15 inch Diamond TDX.

Thanks again one more time guys!

ok first off reconcider the alpine type r .. and type x they are not low on the totompole by anymeans ... and if you think they are .. you have never heard them ..... and if you did hear them and still think poorly.. perhaps you could throw another 1000 watts to them and then listen i had 2 x alpine type R s in a sealed box with a MTX 8100d they are by far the best sounding car audio sub iv ever had the pleasure of listening to they hit hard go low and loud and they satisfied me for SQ competition to ... i hit 152 db with the 8100d and 2 type r 12s ... the type x from what i hear is even better and from my expierence i would not go with the diamonds i think you will be disapointed .. unless of course yer like most and just want bass... and dont care what it sounds like
 
The type-r is low on the totem pole, sorry. It's not a bad sub, but it's not that great either. It's got decent SQ and can get reasonably loud, but it's nowhere near the best in either category. It's a good all around budget sub, nothing more. And yes I have heard them, my brother in law owns one, they're good for the money but there is much better out there.

The type-x is better, but it's not without its problems. It requires a VERY large box, cannot be ported, and is expensive to boot. It sounds good, but it still can't get all that loud, not compared what else is out there in that price range.

I'm sorry but I have an extremely hard time believing you hit a 152 with that setup, not unless you were in an outlaw class or were using a very loose mic. Do a windows up, mic on the dash burp on a modern mic/sensor and that setup would be in the high 130s or low 140s at best, maybe a little higher if you had an spl tune, but then you're driving a one-note-wonder setup and have no room to talk about SQ.

I've never used, heard, or heard anything about the diamonds so I can't really say anything positive or negative about them. I wouldn't go with the 12s personally, they have a very high Fs which won't lend itself well to low end extension in a sealed setup. The 15s have a nice Fs though, so that should be fine. Don't pick a wiring config (D2 or D4) until you pick an amp though. According to their specs you should get around 1000rms per sub, that will be hell on your electrical system if you try to actually use that much power, but there's no harm in having it available. How much of a budget would you have available for a sub amp(s)? Also, are you considering upgrading the front stage as well? If not, there's no point in buying any SQ-oriented sub as none of them will sound even half decent without a good front stage.

I still stand by my earlier recommendation, ID Chameleon components, IDMAX subs, PG Xenon amps.
 
i had 2 sets of alpine type r 6-1/2 componants with a 4 channel MTX running them and the 2 type r 12s with a 8100d running them in a perty small sealed box fireing up at the back window in my 84 corvette... windows up mic on the dash and i hit 152db i even had a guy sit on the back window cuz it was lifting off the seal....my friend had the same setup but was useing 2 of the 12" kicker solo baric square subs... and he was louder but it sounded like *** ... as you would say it was a one note wonder.....
 
I was scoping the ID Max subs and there specs seem to be very impressive, especially the excursion figures. Now I am no where a pro and I run three PII subs in a sealed enclosure whch in no way would sound good to you guys but for the type of old school house music I like it works ok. Now if I wanted to relace the three subs with ID's, how many would I need to match the quantity of bass I get now? Polo.. 🙂
 
just a couple more type r vids

The Blazer Doing one heck of a hair trick. Remember, this is just 2 12" alpine type R's! http://www.thecaraudiobox.com/eventpicsandvids/2typeR12hair.wmv

Just showing off! That thing moves some serious air... just 2 alpine type R 12's! A MUST SEE! http://www.thecaraudiobox.com/eventpicsandvids/2typeR12blazer.wmv

this is on type r 15 Does a 122 in a car thats approx 20 feet away! http://www.thecaraudiobox.com/eventpicsandvids/typeR15car2car.wmv



Low on the totempole go figure. not trying to start an argument but in there price and power range they are deffinetly one of the best.
 
Seems like that Orion Amp throws some juice? Now what size and type enclosure do you have the 12's in? Funny I had my windshield replaced 6 mos ago before I put a box in my car and about a onth later when I really got the power up I noticed the seal blown right on top my the mirror. I called the glass place and chewed them out, figured it was a bad install. Well they came out redid it just for it to do it again the day. I later found out it was because of the inside pressure, made things feel better I guess, lol.😀 😉 :smash:
