Help me find some 8" or 10" woofers

RockLeeEV · 8th September 2011, 11:50 PM

Okay, here's the criteria.

This will be for a center speaker, so i might not need much baffle step compensation. I can measure in a bit just how much "boundary gain" my TV/TV stand give my current speaker.

-The midrange I plan to use, is pretty sensitive, so I don't wanna throw that away by using some 85 db sensitive driver. I want to shoot for a L/R 2nd order crossover to save money and maximize integration, though of course if the results dictate a need for something else it's not a big deal. I'm just saying that I don't want to be dealing with big magnesium breakups.

There will be two woofers in parallel flanking the above driver, so we can't have more sensitivity than the mid of course. I of course can't afford to use two 4 ohm woofers in parallel. two 6 ohm woofers might be pushing it too, depending on final results. 8/12/16 ohm would thus be prefered. And since there will be two mids used, cost is a given factor.. no $300 woofers!!!. I would prefer drivers with shorting rings.

Finally, I plan to use a sealed enclosure with subs so I need T/S parameters that give me an F3 of 90hz or lower.

Anyone got any ideas? 8s would be prefered but I can move up to 10s. 12s might be pushing it mostly from cost and aesthetics perspective though I think it'll physically fit.

Thank you for your time.

Right now the Seas Nextel W22 models almost perfectly for what i'm looking for, but at $500/pr i'd really prefer to find something similar but cheaper.

Does anyone have any experience with the Dayton RS270-8?

H1471-08 CA22RNY ? cheaper.

8" from SB acoustics is my favorite.
SB Acoustics :: 8'' SB23NRXS45-8
6o L closed box with two woofwers should get you in 90-91dB range including BSC. Lot of pleasure with punch and kick bass. I dont even need a sub as this combo goes low enough in my 26 m2 room.

And for centre...dont need 60 L, just mount em in something smaller like 35L box and you get response somewhere in your range.

Maybe the 8008-Center could give some inspiration

For 8" woofers, this and the Peerless 830869 are currently my top two leading options.

I was shooting just a smidgen higher - 93 or 94db. I might consider one for my car though

If the Radian was just a bit more sensitive, I would use a prosound driver like B&C 8" but i don't see it working passively, and I'm not bi-amping my center before my stereo mains

I know there's some more sensitive coaxials, but i'm leaning towards this one either way.

The 8008 was the first driver that came to my mind but cost and parameters were pretty off. I wonder how much it differs from the CA22RNY in the bass.

If I were doing a WTMW that seas 4" midrange driver that Troels used, is probably the same one I'd use. But I've already decided to go WCW. My inspiration was the JTR Triple8HT-LP.

I've used the RCF L8S800 in a ported bookshelf. It extends down pretty good.

Why parallel woofers?
