Full Range Drivers

I can't disagree. I've never heard one. I find your response appropriate considering the lack of information I provided. I'll try to see if I can demo some Tannoy's. I've heard that some full range driver configurations do a good job of reproducing vocals, I would imagine if implemented properly. I think my 3 ways do a good job, but have nothing to compare them too. I'm under the impression that no speaker does everything perfectly, so maybe I should look into having a second pair of speakers on hand for certain types of music. I'm probably crazy and just going through some weird 'collect bug'.

To get the most out of a single driver, you also need a huge, sometime elaborate enclosure.
And yes, the best can run some real $$$. But, given the generally high sensitivity you won't need a gigantic amp.

I have owned many speakers over many years and have enjoyed several single driver speakers including:
Beauhorns, Lamhorns and KCS seas exotics. None of these are full range in the sense of 20hz-20khz...not even close.
But depending on the room, positioning, music and personal tatse, I have found them all very satisfactory and satisfying...in fact, I would consider the KCS seas exotic to be one of the very best values I have come across.
I currently use Tonian Classic 12.1s which use the PHY driver covering most of the speakers usable range and the treble is brilliantly handled by the Raven 2 ribbon tweeter. This being second pair of Tonian speakers I have owned (original TLM-1s) and a very fine speaker IME.
I certainly like what a well designed single driver speaker can offer but like all speakers you have to pick your priorities and poison.

I ran Fostex Fe166 in a fostex BLH cabinet that I built for under $500 total, ran it with a Thorens TT, Bottlehead preamp and phono and Fi X 2a3 amp. It was one of the most enjoyable systems I owned. Very coherent, music that hangs in the air and very ballanced from 45 to 15k.

This is the system I most regret getting rid of in my search for the best. It was a 3K system that played music like an instrument and volcals like the singer was in my room

Fin1bxn. That's what I'd like to hear is vocals like the singer was in my room. I'm toying with the Tekton Kat's Meow. The price is great and the designer/owner of the company said he'd pay to see the look on my face when I compare them with my B&W CM7's. He has a lot of back ground working with various speaker manufacturers and it sounds like he knows what he's doing. With a 30 day money back guarantee and a 5 years warranty, why not have them around? I'd like to be able to chose speakers based on what music on want to listen to.
