recommend me a driver

[Shpoop]

Hey guys. I'm thinking about a new project using full-range speakers, and I need your help in picking a driver. Here's the design constraints:

-Full range (no other drivers will be used, and also no sub)

-Will be powered by sonic-impact T-amp, pick power accordingly (http://www.partsexpress.com/pe/showd...number=300-958)

-The smaller the better (though I know that sometimes conflicts it #1). If possible, I would like to keep it to 2'' or smaller, but feel free to recommend some 3''ers too.

And thats it! Have at it!

Thanks,
Matt

Without knowing the intended application, type of music, etc, it's hard to make a recommendation.

e.g. for a nearfield/ LCD computer monitor application the Fostex FF85K, Aura NS3, several models of TangBand, etc will all have their proponents.

But you might be expecting too much if you think that room filling concert levels with deep bass will be possible with a single pair of any of these drivers, regardless of available power and enclosure design.


Now, if there's any way your constraints can be stretched to 4" drivers, that's a whole 'nother ballgame.

I totally agree...trouble is, I haven't totally decided on the applications yet. The project design hasn't totally cemented itself yet.

I know a single 3'' or smaller won't produce full, thick, room-filling audio...especially by the standards of anyone who visits this board. But whatever path this project takes, design will ultimately be more important than audio quality (preparing to cover my face from a barrage of rocks). And I don't see any design allowing for 4'' cones. In fact the more and more I think, 3'' will probably be pushing it too.

Again, the path is far from certain, but I'm currently leaning towards something that is more geared towards a small, desktop speaker system/portable mp3-player speaker. But as I still consider myself an audiophile, I want the best sound possible out of this design...richest sound, broadest range, etc.

Now I understand why you sit on a 3" sofa, sleep in a 3" bed, watch TV on a 3" screen, have your cooled beer in a 3" refrigerator, and are still on search for a 3" girl friend.

I think the biggest problem here with a small driver restriction is your amplifier - simply put, you don't have enough gain for some low freq. boost. If you did, then you could look at an aura 3" driver.

Note that a 3" driver isn't really 3" - that is usually a dimension in combination with the frame, so the drivers ARE (at least visually) smaller than what is spec'ed.

With such constraints (and the above in mind), I'd choose this driver:

In a bass reflex (vented) design.

you want cheap 3" use TB 871S, I am driving them with a T-amp at the moment sounds quite good.

If you want to get a bigger sound use 2*TB Bamboo, 4" in parallel you will get 95-96dB effciency, which is good for T-amp.

thanks guys.

I know the amp is not ideal, but remember, this project focuses on design, and I needed something very small and that did not generate much heat.

And actually, do you think you guys could limit suggested drivers to 2''? I don't think I want any bigger than that.

Thanks again

2" spks will you sound with small sound image. there is not much difference between 2" to 3".

Well, the amp could be ideal. If you put larger input caps in, the bass curve flattens to around 20 to 20. I did it in myt T-amp and it improved the sound immeasurably.

Tom: that sounds well within my circuitry know-how! Could you please tell me which caps you used? Also, if possible, maybe upload a picture to illustrate where the input caps are on the board?
