okay, I have looked a lot recently for a 12 inch that can do 35 hz to 300hz. quite a hard task for any pro 12 inch I realize... I dont want a cheap woofer either so...
here's what I found:
Eminence delta pro 12
Eminence Kappa pro 12
Beyma 12g40
AE TD12
I'm strongly going toward the Beyma, as its a good price and good quality, but I wonder if the difference of a excellent quality such as beyma or a AE, for my needs (35 to 300 hz), would really make it worthwile to pay almost double for the beyma compared to a eminence.
any help will be great
thanks

It's hard to get typical pro sound 12" (midbass) down to 35 properly. 40-some to 50, yes.
And 'only' playing up to 300Hz, I don't see very much difference in home use application if each of them are equially well tuned.
Ah, 'feel good factor' is another consideration. 😀

How much efficiency do you want? Budget?
The Aurasound NS12-794-4A will do it happily, but is inefficient and costs a lot of money.

yeah, my maximum is 300$ per driver, but thats really pushing it...
maybe this one is the best beyma for my application?

The Eminence Lab 12 is a good value, and does quite well in the 35 to 300 Hz range.
It has almost double the Xmax (6 dB more output potential) and costs less than the Beyma12B100R you listed.
The screen capture below is an outdoor half space 2 meter measurement of a 5.9 cubic foot Lab 2x12 cabinet with a 36 Hz Fb, no damping material at all as it is normally crossed over at 100 Hz. A BW24 low pass filter was engaged, but it does little to the LF response.
The peak and dip around 315 Hz is a port resonance which could be reduced or eliminated with some dampening material.
The response would be the same with a single 12 in half the cabinet size.
Depending on the crossover used, the port resonance may not be a problem crossing at 300 Hz, since it is mostly a dip in the crossover range.

MTC,
The Eminence Delta and Kappa pro 12s don't make much bass, but are OK up to 900 Hz, the Lab 12 makes lots of bass (5-6 dB more clean bass potential than the Beyma), but not so good above 600 Hz.
Are you talking about the mid/bass Eminence drivers you mentioned in post #1, or the Eminence Lab 12 woofer I wrote about in post # 7?

What do you mean by "from 35Hz?" If you're talking -3dB or 0dB, none of the ones you listed are going to want to do that, except maybe the TD12S in a large enclosure.
The 12B100R you listed later on will get there, but not with mega high output (maybe 108dB?). The cheaper 12BR70 actually goes a lot louder in the same range, looks like.

According to the datasheet the Beyma 12G40 reaches only 53 Hz (-6dB) in a 30 litre box. And this is even optimistic...
yeah, so the 12b100r seems to be the best option. Beyma Speakers - Beyma 12B100R speaker - Beyma 12B100R 300 watt 12" woofer for all hi-fi and studio monitor bass speakers. Beyma 12B100R and other Beyma 12" speakers here.
I never listen to music past 100 db, and mostly, my listening habit is around 70db, so no need for high output at 35hz.

yeah, the lab 12 would be good, but no in long term for a higher crossover point...
I thought that the kappa pro 12 could have reached in the 35 hz, seems I was wrong. so the best option is probably the 12b100
Murphy, you are not answering the questions.....
Why do you need a pro woofer? Sensitivity?
35Hz? -3, -6, -10?
Ported? TL? Aperiodic?
Why not a 15" like your last thread stated?
Why 300Hz crossover?

I want a pro drivers because I have been suggested then the dynamics are better.
I cant do a 15 inch because I have a WAF situation. a 12 inch is the ultimate limit, and its already pushing.
I want to cross over around 300 hz to the alpair 12 p FR. I think that from 300 hz, the alpair can take over, but I'll have to play around for that once I have chosen my bass drivers
Idealy, 35hz -3...
I have not yet decided wich box, something like vented probably to permit me the most bass extension..
Wow. You are not asking for much. (pending on box volume)
Size restrictions? SPL/W wishes? I would probably agree on the BR part, not for bass response but for the top end response. the 12BR70 is nice, value for money.
You can cross the alpair much lower.
Also, you can side mount a 15.
I think this is the best way if you want high sensitivity and extension.
This way you could have a slimmer baffle and the wife would be happy.
Or, you could side mount 2 lower sensitivity 8 ohm woofers and wire them in parallel. This last example opens up alot more options.
Also, if you side mount 2x12" on opposing sides, you will knock down 2nd order HD.
How about 4 of these per side....
Tang Band W6-1139SIF 6-1/2" Paper Cone Subwoofer Speaker 264-919
You can wire them in series/parallel for a 89db 1w sensitivity.
N impedance 4ohms.
1.5ft3 enclosure for -3db at 35Hz.
You can front mount these for a very slim floor stander.
Cross to the alpair at 150 or so.
There is a 2db difference in sensitivity between these and the alpair but they would be a good match at this crossover frequency. It will compliment room gain.
Iv'e used this driver in one of my builds. really nice, small box.

yeah, the 12br70 looks really nice and is really cheap at 125$, how better would be the 12B100/R compared to the 12br70?

@Melo: I dont want to put the driver in a side mount because maybe that woofer will be used one day in a 2-way. efficiency is not a issue here, Im going active, and I dont want subwoofer, I want efficient pro woofers.
