Hi efficient speaker, bass problems

Wes, yes you read a bit of attitude from me.
The 500 hZ statement was added by you, I don't recall just how
Far it was capable of, but I crossed it at 400. I took issue with you
Proposing that it was clearly not possible for the driver to perform
As I had claimed, when in fact it did. Even when I gave you the part
Series, you challenged that it would be easy enough to model.
Sorry for short & abrupt typing, I am out of town typing on my phone

Atmasphere, I'm not disputing what you say about the TAD system, it is a multiple driver system not a 2 way, go back and look at my original response, i said the correct way is with a multi-driver system , no one driver is going to go from 30-500+ hz IMO and still produce high sensitivity it would also produce 2 much distortion IMO.

The OP wanted to know why weak bass, this is what we are attempting to discuss not bashing, but we do have a few insecure text book nimrods on board who believe we all should be Horn Borgs and any disagreement is bashing or hating, of course present company is excluded .. :)

Dan does your horn system have bigger woofers than your Aerial?

OK tim ...

Weseixas, you wrote:

I guess I take issue with this. The TAD driver I mentioned does exactly this range quite easily, and does do at 97 db. Yet it is quite fast and transparent.

But more recently I have heard some field-coil powered 15" drivers that are even faster and more transparent, and cover the same range yet are more like 98 or 99 db (without a horn). It is used in a speaker that got 'Best Sound at Show' in TAS' CES issue a couple of years ago.
