Hello.
In my music system I have two sealed DIY boxes with 12" Rythmik kits in. Want to build one or two additional sealed boxes, this time with pro drivers and powered from a class D amp. FWIW, all subs will get the same summed mono signal. Going for a distributed bass array.
What are generally regarded as good sub drivers from Beyma, Faital, 18Sound, etc? Want to keep them in the 8" to 12" range.
Beyma 12LX60 is good and pricey. Won't need that kind of Xmax as the DBA places lower demand on each driver. Smaller drivers allow smaller boxes which are easier to hide.
Thank you!

Why pro drivers? Modern hi-fi drivers are better suited for small closed boxes. 8 to 12" pro drivers usually are mid drivers, so not designed for bass duties.
I'm not sure if a DBA places a lower demand on the drivers. Half of the drivers aren't contributing to the sound, while the others have to work without room gain and room modes.

There are pro (mid-) bass drivers in those sizes.
That said none are useable as subs and none I can think of work well in a sealed cab except may be the Eminence Lab12.
If you can accept ported speakers (and why not?) the BMS 12S330 could work. It's cheaper in Europe than the Lab12.

Are there limitations on the enclosure volume or depth? How much output do you seek? What is the available budget?
If on this road, here a cheaper alternative to 12s330, 114€ with delivery : MAG M1270R - 4 ohmi
Free delivery with payment at delivery for > 500 Lei with GLS, at least in France.
Here a interesting test of a mag audio speaker : Test Bench: MAG Audio 10N501 Woofer | audioXpress
Those seems beast really well built. Even longer voicecoil than the BMS.
Ported could be. I'm in LatAm, and BMS not readily available. Nor MAG (had not heard of it before). Eminence is available, though. Will look into it.
Thank you!
They are always there. Considering the multiple units, smaller is much better. Hoping to stay under 40x40x40cm
Budget...don't have a hard number. Don't think I need to break the bank for this application either. Should be able to satisfy with about u$150 per driver I think.
In the given link, they got two in stock, payment on shipping, and free shipping, from romania ^^...Look at their photos...
Sorry, not going to import from Romania into Argentina. That would be suicidal. Easier options much preferred.
Charles Darwin talked about price in europe, i thought you were from a north european country that i didn't know the flag. I laught about myself On your side of atlantic, there's the PRV 12w1600 that would interest me. Do you have a argentina shop online link to give to have a idea about prices and availabilities of brand ?
Eminence 3012lf is pretty good as a sealed midbass. Using Rythmik 12in and 3012lf sealed would be the 12in equivalent of this build. Very nice.

Did a quick search in local websites and the availability is more limited than I assumed even for pro drivers. Bummer. Turns out I will be importing from the US after all (easier from US than EU). So "modern hi-fi drivers" are an option.
Currently the leading candidate is Eminence Lab12, about U$220 in the US. Any better or cheaper options?
What about Beyma 8BR40/N? 30Hz Fs (vs 22Hz for Lab12), U$70. What I like about this one, apart from price, is the smaller size would allow easier concealing.
You're from Argentina? You're right next door to Brazil, which hosts build houses for a number of pro audio companies, including Selenium and PRV.
In your case though, I'd suggest going for a good home audio driver, if you're planning to build sealed enclosures. I suggest checking to see what's available in Brazil - you might be surprised.

Sorry, forgot to address PRV. Yes, not only I'm from Argentina but also travel to Brazil monthly, so PRV was a natural option. Looking around it seems their better products aren't marketed locally...double bummer! I will make some calls during the week and see if I can source the better drivers in Brazil.
Which driver were you thinking about?
I wasn't thinking of any particular one, but if I was near to a country that actually had a few build houses, I'd be paying them a few visits
I think Bravox is done out of Brazil as well. They're mostly car audio stuff, but you may find a subwoofer driver or two from them that might do pretty decent at home in the right box.
If you are ordering from the US, the Dayton RSS315HO might be an option at $165. It has a stiffer cone than the LAB12 (higher cone breakup frequency) and it has got shorting rings in the motor structure. Such woofers with a strong motor and strong cone can be put in small sealed enclosures and can rely on an external equalizer to reach 20 Hz.

If a larger cabinet and slightly less output is acceptable, cheaper woofers are OK as well.

The given constraints of 40x40x40cm, assuming outside dimensions, results in a net volume of ~40 litres. Getting any subbass from a 8-12" woofer in a 40 litre, sealed enclosure means you need to look at hifi type drivers. High efficiency, pro drivers og 8-12" size are middbass or midrange drivers, and will not be able to provide subbass in a sealed enclosure without massive eq. An array with large enough number of drivers may have the headroom needed to pull this off.
The Beyma 12P1000Nd works in a sealed enclosure, but a 40 litre enclosure wit this will be 24dB down at 20Hz, and this is not a cheap driver.
The Dayton suggestion above is much better imo.

Modelled in UniBox the Lab12 and the Dayton RSS315HO. 40 liters is not a hard constraint, but used 40 liters for comparison purposes, and sealed (for now).
I still don't know how to insert an image inside the text in a post here, so it's attached. The superimposed FR shows the lab12 having more SPL for most of the usable band. Am I being unfair to the Dayton? For the % price difference it's not bad at all, but additional $55 get me about 4dB SPL extra, which seems worth it.
