Pro woofers with high-end hifi specs

I use the Beyma 15LX60v2 in a two-way speaker. Although I would personally prefer a low fs, large Vas, low Q Woofer this one (Low Vas, highish fs, highish Q) can also be tuned quite low and doesn't cost an arm and a leg.
I use them in 140 Liters per driver, tuned to slightly below 30 Hz and this gives a gentle down-slope with -6 dB @ 30 Hz.


It looks as if this monitor is using the same woofer:

Model 5

And this two-way home-cinema and hifi speaker with an AMT as well, athough I wouldn't use it up to frequencies where an AMT can be reasonably crossed:

Lucas LCR – Aurea Speakers

My previous setup had LAB12 bass stands, eminence beta 12cx coaxials. the 15" faitals feel better, don't go as low but still low enough to be enjoyable, using with 8" mid and horn as threeway. Much more slam, better sound, I think I prefer the 15" to 12".
 
I've got no other subs to compare, but yeah lab12 pretty versatile unit and not too expensive. Can be used in small sealed, or bigger ported or even bigger FLH 🙂 It is getting old so probably there are some newer drivers with better specs. I don't have a glue where is the good price point, bang for the buck. But, my personal preference is currently that bigger is better 🙂

D.A.S. Audio 12P - 12" Low frequency

I bought these das 12p for car door use, car changed and these has been laying around for a while.

i dont have any box for 12" so i took quick loud measurement near dust cap from naked driver.
it sure is worth 103euros does not sound that bad. these has been for sale for awhile but nothing seems to sale because of corona, i think.

I might use these on my project up to 400hz

Is it about the bigger Sd or the bigger air loaded mass than people still prefer bigger speaker for upper bass purposes ?
 
^I've got no idea, it is just quite a different thing with a big woofer, tactile feel, than with small speakers. The 12" did it too the tactile feel, but with 15" it is kind of more obvious perhaps. I don't know if it is just matter of SPL and nothing to do with SD. Anyway, hopefully I can keep the large ones in the livingroom. There is no return to smaller than 12" for the mains for me 🙂 I've never heard speakers that have many smaller drivers with combined SD of an 12" either.
 
I can understand such feeling from experience. Trade offs, myself I never liked 15" above 200/300 hz, always found voices not acurate here, could be y ears, rooms, biass, of course. 18" at 200 +F3, just forgive it - YMMV ,as Troels G.-


The L II is his prefered last friver ? Amen; look for not about PA but the smoothly diving curve above 1 000 hz... amen ! (and what about PA if tons of Z resistors in front of them ?)
 
Hi Mark100,

In what way is the BMS 18n862 better than the Faital 18FH500? Thanks a lot!

Best regards

I recently built a pair of single 18 bass-reflex with the 18FH500, the neo version of the 510. (Weight was important, each box weighs only 58 lbs !)

Built to go to 40Hz, and run in a vertically stacked and coupled pair, cone to cone, to reduce vibration. The coupler is a separate piece.
Here they are under a synergy build.

Great driver !

Also have the bms 18n862, that Troels likes so much.
Use it both sealed and bass-reflex. It is a huge uptick from the 18FH500..

My first PA speakers were original DAS RF12s, with those 12" drivers.
Good boxes.
DAS were using them up to about 2kHz IIRC.

You'll have fun with those.

I have found PRO drivers tend to be a little lacking in detail at the low level SPL's that is usual in domestic settings, possibly because they need a bit of power behind them to 'open them up'. Typically PRO drivers are designed for high level output and are constructed to rigid standards to survive such an onslaught of power. High level SPL seems to be the fundamental design feature as against clarity of detail.
HiFi drivers for domestic use are usually more refined for detail and clarity.
There are exceptions to the rule of course.

Bulldust, you don't know what you are talking about!!!!!!!!!!!!
 
...I was offering my own personal opinion based on my previous experience with such drivers of past years.

When stating such a broad opinion as you did in your original post, it would be helpful if you would also state which pro drivers you've experienced and the implementation on which you are basing that opinion. That might give you a bit more credibility.

Were 15" pro TAD woofers included in the formulation of your opinion? I would think probably not.
 
I'm looking at Eminence Lab 12 because I can get 4 of them used(like new)locally for a great price.. Comments about pro sub drivers lacking at low levels is making me think about it with more caution.
I have 2 lab12's in sealed boxes and they certainly don't lack at low levels. They play clean and go low, but are not the most efficient pro drivers; the regular trade off.
The only negative thing about the lab12's might be their weight.
Sealed sounds best and 4 will output more then enough most neighbors and homes will tolerate. 😀 Better get them.

Drivers that are good enough to leave no practical reason to upgrade in the future. For outright detail and dynamics at moderate volume levels, with enough extension to satisfy most music. Are pro components available that would compete with top consumer products like Excel and Revelator?

FaitalPRO seems to have a number of 12-18 inch drivers with relatively low mms, high Qms, smooth response, and unusually low Rms, such as the 12PR320, 15FH520, and 18FH500. All priced very reasonably if ordered from Europe.

Are these still lacking compared to the best consumer drivers? Are there other examples of exceptional professional components?

Would I be better off forgetting the high efficiency components and going with something like the SB34NRXL75-8?

I wish I could try them all, but spending many thousands on speaker drivers is not feasible.


Excel or Revelator are sure not my references so maybe I wouldnt be of much help, but what I can say is Faital Pro are my favorites among PA drivers, along with Volt which is more studio oriented not PA per se.

The 18FH500 is absolutely stunning. Even handheld, no EQ, the sound that comes from that beast is fantastic.

The 15PR400 is also awesome. Both have specs that seem to defy the usual ''audio laws'' of drivers... 🙂

Even the small 3FE22 and 4FE22 are absolutely great for what they are. You can basically replace a tweeter with them, while have an extremely good (and loud) midrange.

Hi Pk,
It's simply a more powerful driver that goes lower.
Over 2x displacement, with a stronger motor.
I can get nearly 10dB more out of it at 30Hz.

And this is some pure conjecture....
I agree with folks who say minimize excursion for lowest distortion...when talking about sustained pure tones.......
But excursion can be a really good thing.
Watch a sub driver on percussive hits...how it jumps...and on on infra like a space x landing / launching.
Big Xmax is a part of realistic sub performance imo
 
Same here.

Scanspeak drivers are very beige.

It's pretty much like cheese; you start with those soft almost tasteless industrial cheeses, but you end up with very tasty flavorful Époisses, Munster or Roquefort Papillon cheeses...

Scanspeak drivers are basically the ultimo drivers for passive speakers: they require less EQ, they are pre-tamed, they are very obedient. And you pay exactly for that. 🙄

The other price to pay is low efficiency. Sometimes, very very low efficiency compared to the best wideband/fullrange/PA drivers.
 
They are not lacking at all, just the lowest frequency range that is missing sometimes, but usually that's worth it even for home use, if you ask me. But they can go as low as 30-35 Hz (or even lower with some models) in an adequate cabinet and tuning if room gain is considered.


The 18FH500 and even the 15PR400 can produce decent low-frequencies, and even though I would rather use them in combo with real subwoofer drivers, they can work very well. I'm playing with the 15PR400 right now and I will soon give it a try with passive radiator in a moderate sized 40 liters enclosure. I will probably need a lot of EQ, but I expect something solid starting 25hz.
