i am wondering if changing the driver on these
will improve the response
Nady PSW15 600W 15" Subwoofer | Musician's Friend
i know that at that price the wood and the driver must be crappy
but right now i cant afford high end cabinets
i was looking at some
EAW: SB150z
but the cost like 1200 each...
or something of these guys
http://www.community.chester.pa.us/...f?phpMyAdmin=c9cc5b3953d87385dc22218d669e7aab
but the cost is prohibitive for me
is there some plans to build something similar with a 15" or a 12"
i need a simple sub that you can carry easily and since i carry it on my car
an 18" cab is out of the question
i was looking at the behringer one but they only make 18" 's
i need a 15
Now , what is better a single 15 or a dual 12, sorry for the newbie questions
but i am new to speaker cabs
and i want to maybe build a simple cab for myself
or get a nady and spice it up a bit
Thanks
Max.

Do you already have the sub? Here is my design in process with a driver that would work well in that box:

No but it will arrive next week
i can take measurements and stuff from it if u need it
As there is no plans specs on the net
how much cost is to complete one of ur cabinets
Exotic high end cabinets are nothing more than thicker plywood. Subs are easy, cabinets cheap. Cheap subs have cheap drivers and cheap amps to go along with their cheap box. You can DIY a really, really good sub for under $500. Not sure spending any money improving a really cheap sub is as good as setting that money aside to save up and build a good one.
Depending on the cone material, there is room to play. If it is untreated paper, you can dope the cone to damp breakup modes to make it cleaner, then remeasure the T/S parameters and re-size the box and tuning. You may get a few Hz out of it at the cost of a larger box and a tad less efficiency. You also may make a mess. DIY always has that risk

My all time best sub is a Peerless XXLS 12 inch in a 60L box, sealed. In room with a solid floor it gives just the right bottom end for music. No eq. What they do is lower distortion than about anything else.
A pair of them and a used pro sound crossover and you are in business to laugh at some really expensive stuff.

where you can get them and what boxes you can put them in
or what plans to build your own
if it is a 12" i think the box will be smaller than on a 15" and better for me
as i can load it in the car easier, maybe a pair of those
but take in account that those will be used for PA sound and not in a home theater installation

The Peerless XXLS drivers are widely available. Mine are the older paper/carbon ones.
They are in just a 60L box made of 3/4 plywood and stuffed with fiberglass and spray can black. You could build them with a hand saw and a bottle of Titebond. There were two published articles on this driver, one was something like "low Q sub" and the other is the "Thor" on Linkwitz's site. These are home music subs.
Now, you say this is for a portable PA system. That could be a totally different use case. EXACTLLY what are you going to use them in? How big a room? Outside? What kind of music/signal? Just PA or are you going to try and pump a piano or upright bass through them? (Actually, if not, then what do you need subs for?). What are the main speakers?

i
brasing will help to prevent the plywood deflection and high volumes ?
and what woofers you suggest for it
i will measure the thickness of the "wood" that came with it
and report back also will remove the driver to see what cheapo thing it is
it will arrive on Wednesday
i get it at my local Guitar center but they ordered as they dont carry it
locally
they tried to sell me a 599 harbinger 15" sub , but i said no
internal brasing is like the SS15 design ?

if you post links to the projects i will appreciate it,
i have a crown xls 2000 power amp that , that i will use one channell full range , the other channel for the subs
i will start with one sub and one full range speaker , later i will add another sub and another full range speaker
to load the amp at 4 ohms instead of 8 ohm on a single cab per channel, my full range speaker is an old peaver DS1502 15" cab with a compression horn driver ( 22xt )
so i get the nady 15" sub to augment the low end
i will play in restaurants ( inside ) and homes and also home patios and porchs
and outside decks, i have a trio band, we play with 2 acoustics guitars and piano with a drum machine, on some songs i play the bass with the left hand
so with the drum machine and the bass i want to have some really punchy low end going
if the XLS2000 do well with that setup i plan to get another one and get another 2 subs and full ranges
in the end i will want to have 8 subs to put 4 on each side of the stage and 4 full ranges
for now , i can move with a car, but later i will need to have a truck to load all the stuff
so right now only one sub and one full range
XLS2000 can

Maxo,
The Nady is not something I would not buy even for temporary use.
It looks like you have long terms plans for the band/PA so I'd recommend you think in terms of performance and longevity. You can DIY some truly amazing stuff, that if you had to buy as a commercial product would be WAY out of the average budget. If you can't build it, ask and we can find you some help.

Sorry for the duplicate post above ( there is no delete option and i cant edit either )
Hey Neo
Sounds great
i think for now the 18" subs enclosures are out of the plan because i dont have a truck , so 15"s or even 12"s would do
a single 15" or a dual 12" or single
so what would be my options
Thanks Man
Max.

For "acoustic" style live sound JBell's SS15 is probably best bang for the buck/size if you are going to build out to a bass stack.
I went and had a look at the manual for this amp... I don't think I'd use it on subs there is no way to create a bandpass filter to high pass the sub to protect it from over excursion below tuning and then also filter off the highs. Kind of a dumb omission for an amp with modern DSP. The Behringer iNuke DSP series NU3000DSP/NU6000DSP have really good DSP if you can get past the name.

Ohhh great so where i can find the stuff for the SS15 sub
i got the xls2000 because it was at a very good price in mint used conditions i get it 240, new they cost 499
and yes you can split in in to high pass low pass , i pasted this from the manual
only thing is that it dont have the bandpass for the lower section where i can for example say... cut all the crap below 30hz
so i guess i will need to use a minidsp or some pasive box that will do a high pass at 30hz , kind of Subsonic filter
Look for a Behringer MIC2200 it's cheap and the parametric high pass filter can be dialed in to whatever you need.
what you think about this thing
PFMOD HP-Sub
but this have a 18db slope so i thinh the cut is more sharp
http://store.hlabs.com/pk4/store.pl?view_product=11 and cuts at 37Hz
this one looks nicer but i think it will cost more
