I am looking for suggestions on a mid driver that has a little boom to it that I can make an MDF adapter and mount it free-air in that location. This would be powered off the QAA1000 about 250W per side. Any suggestions?

i have some coustic DR 306 6.5" subwoofers/midbass ( i was going to cross them around 60-400 hz) you can buy for $55 shipped :D

they can handle around 100wrms. 4ohm

I need something that I can use the power on tap.

If they're high passed couldn't 2 more M6's handle close to that power?

How about the Tang Band 6x9" subs?

They're 8 Ohm drivers and rated for 90w so an output of 180w ~ 200w @ 4 Ohms would work well for them...

With the gains on your Quart 4ch set conservatively they ought to work pretty good for what you're needing.

Add to that you can get a pair of them for <$100 BNIB and this option gets even better, no?

Peerless SLS8s if it is midbass only (60-250hz)

I always thought a round speaker was better? Would the TB's mount in a 6x9 opening or is MDF required?


Another thing is I don't know where you order TB's :wow:

I imagine the TBs would mount in a ByNine opening as they are a 6"x9" driver...


You get them from Parts Express...or, ----> here (http://www.partsexpress.com/pe/pshowdetl.cfm?&Partnumber=264-837).

I dont know any 6.5" or even 8" that you will be able to free air with 250rms...

If you made some enclosures you might find something.

The TB 6x9 Neo (http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=264-864) sub is on sale right now. $49 marked down from $79.

As is the 8x12 (http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=264-838).

free air 200 watts? on a 6.5 or 8"? ehhh sounds like a bad plan all around

Both of those, however, are 4 Ohm drivers and I'd wager not quite up to the task of taking the amp he's wanting to drive them with.

The 8 Ohm version of the TB ByNine 'sub' as I posted earlier would be a much better choice when considering the power he has on tap @ 4 Ohms...

Isn't the QAA1000 a mono amp that puts out ~1000w rms at both 2 and 4 Ohms?

Seriously, go read some reviews of the Peerless SLS8 on DIYMA. It will do what you want. Recommended power is 125 watts @ 8 ohms. They will blow your ****ing mind.

I believe he meant the QAA4250 4ch that's listed in his sig as a Front & Rear amp...

I guess the ideal range would be 20-5000 or so Hz. Is that about right?

That's very difficuly if not impossible to do with a mid. Sub-bass (subwoofer) frequencies are generally 20-80Hz, and most good midrange speakers will play from about 70-5000Hz (most can max out higher, some will max out lower).

These are very generalized numbers, its going to be driver/install dependent:

SUB-20-80hz some will play as high as 100hz
Mid-bass-80hz-200hz some will play higher
Midrange-200hz-4000hz some will play higher

The Tangband are nice for the price. IMO the Peerless is better.
Other's to consider:
CDT M6 and M6+, 06/06+, 07
Old school kicker 6" sub one with stich sourround if you can find them.
Check out Seas/Peerless/Dayton

I am sure between these two sites below you can find a driver that will meet your needs.

You can look at Seas/Peerless/Vifa ect at www.madisound.com

Nice post! Mid-bass is what I want. Just a tad out of the bass range enough so it isn't quite a sub and plays music instead of beats.

I've added critical mass ss82's to my rear deck for sub duty, I've also had DLS OA8's and AA Assassins.

The SS82's are taking 550 rms each without a problem and sound very nice in my rear deck, the AA's had 80 rms each going to them and they did sound pretty good doing it but I wish I had more power to them. DLS were very nice as well, more detailed and probably more along the lines of what OP is looking for. Low bass output is nice however detail is more noticeable in this driver.

Still looking around. These would have to be free-air and I have 250W per rear channel @ 4 Ohm.

What is your budget for each driver?

Buy a pair of rainbow power line cs woofers :D ~40hz-5000hz. Wee! Rainbow specs say 35hz-5khz but i think that's a mild exaggeration.

HAHA that's exactly what I was going to suggest depending on the budget!

Either the SLC Kick mids, the Germanium mids, the CMX Kick mids, or the CS mids. :cool:

I guess my space has really narrowed it down!

I just went and measured and with the x-bars a 8" is a for sure won't fit. It is either a 6x9 which these Focals barely touch the bars or a 6.5". I think I have decided to just fit another set of M-6's back there.

How about the 6.5" TB subwoofers (http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=264-832)? You'll have to be a bit conservative with the gain setting.

Intercooler

I ordered a set of the TB 6.5's you posted just in case. When I measured I had 3.5" to the bar from the deck but with 1/2" MDF to mount it up it may clear. If not I could possibly shave it down or try to find 3/8" MDF. Wonder if they will play better than the M-6's? The M-6's are only 3" mounting depth so they should be cake.

Anyone ever listen to those TB 6.5's: http://www.partsexpress.com/images/264-832m.jpg

Try using Masonite (sp) board. The stuff peg board is made out of minus the holes. I get mine at Lowe's. Cheap and is useful for a lot of things including making adapter plates.
