Default Help choosing a 10" woofer for compact powerful cabinet

I'm wanting to build a compact but reasonably powerful pair of cabinets. I currently have a pair of selenium d220 compression drivers and would like recommendations on a good 10" woofer to use under them. I have found but have no experience with,

What do you consider 'reasonably powerful'? That CD can approach 135dB so there are no limits there. Getting even a stellar 10" to go to even 125dB will take a lot of juice. (97dB with 1000w = 127dB)

What are you hoping it to compare to in size and performance? Are there any commercial speakers you have experience with you could reference your requirements to?

If you want to go 'fairly powerful' (around 120dB) then you're spoilt for choice, and honestly the Selenium CD and the horn you attach it to will end up being the bottleneck, not for output, but for quality. Not that it's so bad but it's a fairly budget option, so you might want to match it with a budget driver.

But if you want to go 'loud', (125-130dB) then you have to pay more, and/or consider a 12" option, and in either case you would need a powerful amplifier (1000-2000w per channel)

The BMS 12n803 would be the dream option for a compact midtop, http://www.bmsspeakers.com/fileadmin...ta_2011-10.pdf offering up to 129dB in a 20 litre enclosure, but it costs twice as much as any of the options you listed, and needs 2200 watts per channel to reach that level. Not beyond the means of a lightweight and fairly budget Behringer iNuke class D amp though.

FaitalPro can go a little bit louder simply because they offer some high powered 12" with 12.45mm excursion, but they're only a few quid less than the BMS, and for quality you're better off with BMS (who unfortunately don't offer any 10" woofers).

You don't desperately want to be driving your woofers that far into excursion when they're responsible for a large part of your vocals anyway, so the less your cone is actually moving at the volume you require, the better.

The Faital 10HP1020 is about 200 Euros and can go seriously loud in an absolutely tiny box. 125dB in a 9 litre enclosure, but again it's extremely power hungry. 2200 watts to reach that level, and, somewhat unbelievably per the spec sheet you can actually feed it that much in carefully limited peaks (it's rated at 1400w program 2800w peak).

However the BMS12 I mentioned, in a slightly larger but still very compact 20 litre enclosure, can produce the same level, 125dB, with just 800w of amp power (so again the Behringer iNuke may be suitable, but the cheaper, 1000w per channel version instead of the 3000w per channel one), and it will only be running at 5.75mm out of it's 9.3mm excursion capacity, which means much less distortion when running full tilt, and it's a much higher quality woofer to begin with.

The BMS is rated at 4000w peak, and obviously you would never be putting close to that much into it, but it also means it'll perform excellently at a lower 800-1000w power level, due to lower power compression losses. This could translate to as much as +2dB long term SPL versus some lower powered alternatives.

I found it for sale at a bargain price on this Bulgarian web retailer, BMS 12N803 | 12 inch | Високоговорители | Професионално аудио | Продукти

It translates to around 225 Euros. The cheapest this driver is available in the UK for is 300 Euros, so even if you're importing to Australia it's still cheap. Not cheap, obviously, but for what it is? A bargain.

Edit: Disclaimer - this post is riddled with assumptions and hyperbole which I hope you can look past and have a look at the woofers yourself without paying heed to any of my waffle.

Hi and thanks for the responses. I currently have a vintage jbl sp212 and sp215 cabinets and they sound great but are big and very heavy. My goal is a cabinet less than 25lt capacity, bass to about 80hz. I don't need >120db. The faital 10hp1020 looks like a beast, maybe overkill.

I use Faital Pro 10FH520s in my PA, and have a pair per side wired in parallel to an NU6000 (around 1KW per driver). Even when you're really hammering them, they sound great.

Thanks Chris, I've read one of your threads on building your top boxes, interesting. what was your criteria in choosing the 10fh520? was it the demodulation ring?

To be perfectly honest, I found a set of four of them on eBay, and made an offer and it was accepted. I was looking for top-end 10-12" PA drivers and got those.
Demodulation rings are a Good Thing (TM) in my opinion - it's a good method for reducing one of the bigger contributors of distortion. I haven't tried the 10FH500 (same driver, no demodulation), but I can say the 10FH520s are excellent.

I've put a live band (including kick drum and bass guitar) through those tops, with two ports blocked for a 60Hz tuning frequency. Lighting up the -6dB light on the NU6000 regularly, they were enough to keep up with a loud (moderately deaf) drummer, with a good amount of "feel" to the kick drum and bass guitar.

I'm considering downsizing the tops to a 1x10" + horn per side, with the option to add a second 10" for bigger events. Most of the time, I don't light up the -6dB light on the amp, meaning I can get away with smaller boxes for those gigs.

Chris

Heinz1964: Got Monacor SP-8/150Pro. Nice driver, but nowhere near the "drag race PA competitors". It really needs hela lot more motor force and coil mass.

I have both SP8 and SP10, both are nice drivers SP8 has 2" voice coil and +/-6 mm, SP 10 has 3" VC and +/-7 mm linear travel, compared to a lot of other Pro woofers thats a lot of linear travel.
