Woofer adivce to match my tweeters

[IG81]

Hello,

I have grabbed two of the following tweeter for a good price at a local store sale. They are very efficient and can handle a lot of power. I'm looking for advice on a good woofer to match to them, around 95db, not too big ~6" to 8" that can play up to ~3kHz. Any recommendations?

Thanks!

what design are you going with

w- T W M T W T W T WW budget or total high end
2nd, 3rd, 4th order cross over
I would suggest going here to start http://www.zaphaudio.com/
I myself like this brand http://www.madisound.com/catalog/index.php?manufacturers_id=150

and if you have a lot of money

There is no 6-8" woofer with 95dB sensitivity.

Either get a pro midrange with this sensitivity or expect 5-8dB less sensitivity.

maybe consider these in an mtm and pad down the tweeter.at 16.00 each,it may be worth a try.i was told the specs are the same as S164WR2608.

No specs?

I thought I might bring you good news, as I had made the following note:
"Tang Band W6-789S 6-1/2" 92dB Woofer $44 Parts Express," but now when I checked again it appears they no longer carry it.

Making an MMTMM could bring up the efficiency, but that many drivers kind of defeats the savings unless you find an awesome deal. Madisound has a $13 Vifa that might be cheap enough? Check the specials.

there are some on ebay

I don't think you are going to find what you are looking for. That kind of efficiency is only found in pro stuff. In a 6'' or 8'' you are looking at a pro mid.
On the other hand, if you are looking at a low cost high quality speaker with decent efficiency, these may suit your needs in an MTM. Look at these and give Chris a call at Solen.
Canadian prices and no import costs.

Thanks for the links and resources guys!

I'll be looking into that. I would be a shame not to use these tweeters or to have to lower them to 89dB...

 

[IG81]

I might (read: have to) compromise on this one I guess.

I'll try to find two 4" to 6" woofers per channel around ~89-90dB each and bring the tweeter down to ~93dB. That way both ranges will be at the same efficiency level and adding a resistor to the tweeter can be good towards reducing the total load reactance.

I'm looking towards transmission lines. One woofer at 1/3*L and the other one at 1/5*L. I'll probably have the tweeter in the middle of that.

One point I'm not to clear for TL's, what kind of Qts do they like to see? I would guess ~0.20 to ~0.50 should be decent...

Not cheap, and still pending completion, but

The AE speakers TD6.5M would fit the bill. healthy Xmax, solid sensitivity, and high performance, particularly up high if you're crossing high.

the JA8008: Troels Gravesen's baby, made by SEAS, sold by Jantzen, but I don't know if available in America:

E-speakers seems to be carrying Jantzen speakers, as of today!

I've always been interested in the JA8008, it looks like an excellent driver, but ~$350 each is a bit too much for me.

Yes, but only $3.68 per db

 

[DcibeL]

If you want to look at it that way, about $3.80 per dB after baffle step considerations.

I use the Peerless 830884 8" HDS, at $1.20 per dB after baffle step and am very happy with it. Better bass capabilities than the JA8008 as well I'd imagine, at least in a regular bass reflex cabinet.

Sure but I guess that what the JA8008 price does reflect is its high efficiency combined with a smooth, unrising fr response and low fs / possibly x-max / average Qts; I don't know of any other 8" hifi or PA driver having this kind of features...Do you?

 

[DcibeL]

It's definitely unique, I'll give you that. The lack of an xmax spec in the datasheet, or I should say the lack of T/S parameters in general is unfortunate. Smooth response is nice, but not a deal maker at that price.

Anyway, I feel like I'm thread-jacking here. Back to the topic at hand. 3kHz is likely the lowest usable frequency for that tweeter, and the $350 JA8008 is probably a poor driver choice to match a $40 tweeter.

Using more than one midrange unit up to 3kHz or above will likely result in some polar issues, an MTM here is a poor choice. A pro-audio midrange used in a 3-way is probably your best bet.

Right now I'm looking at the Audax AP170Z0, 22$ at PE. It goes up to 5kHz, so I could cross over somewhere around 3.5kHz I guess. Two of them would get sensitivity around 92-93dB and thus fit the bill.

How about an Eminence Alpha-6 and a large pro woofer for bass reinforcement? Will make for a bit more expensive and larger project, but should result in a very powerful speaker.
