Which SPEAKER for the 21ST century?

Bishop the Manger full range drivers are married to a woofer that provides the low fq's. The Fostex Lowthers and other "full range" drivers all do well with woofers in the lower hz's. But i'm not sure if the these drivers offer the musicality that i'm after. Can one of these full range do what a great tweeter can do in the upper most range? And like i say these full range drivers are not tube friendly, so count me out. And i've got a feeling i will not be able to use the ATC midrange with in my 3 way kit, for ohm demand. Twl has a Berning amp that works well with his Fostex full range. I'm not giving up my tubes for any speaker.

Ok, Bishopwill, I'll give you the deep organ part of the argument against single drivers. But, the high end is not rolled off on good single driver speakers. Many times a high end rolloff on these is actually the characteristic of the SET amps that are commonly used with them. The transformer on the amp it the usual culprit in rolling off the highs. They will "beam" however, so the sweet spot is smaller than other designs, regarding the high freq's.,But a 1 inch dome tweeter beams at approximately 10kHz, so you lose that upper octave if you are off axis on multi-way too. Lowthers will respond within a few db of average all the way to 22kHz. So, we're really talking only about a low end deficiency here. I see the vast majority of speaker designs, even very expensive ones, don't do 20 cycles within 2 or 3 db. So I agree with you that it is a matter of degree as to what level of bass rolloff you can accept. My position is that the increased coherence of the single driver is worth the tradeoff of the lowest bass response that you probably are going to get with almost any speaker anyhow. I am not against low bass response by any means. I would love to have 16Hz flat and clean. But, I just don't want it at the expense of the truthfulness of the rest of the spectrum. Pleasant listening and thanks for your point of view. :-)

Twl The big Berning amp + a great full range hybrid speaker , like Lowther , Manger, Fostex will make wonderful music. As well a superior tube amp + superior 3 way will have advantages. Threads like this open the way for better understanding of the speaker factor in the audioworld.

I'm very surprised ain't nobody following up this thread ..like i'm talking to myself. oh well here goes anyway. I posted this on 3-11. Well they've arrived, they will be released in the next week. Seas W26, Seas W15CH, Seas 27TDC. Seas web site shows a photo of the W26, the midrange and tweeter photo will be up shortly.

I'm following, send pictures and thoughts ASAP.
