    Guy here made the cabs originally for tannoys, but they didnt work so i got them off him and converted them to my needs. Not the last word in craftsmanship but they are very strong(double the thickness you see) drivers are 10" each. very sensitive at about 97db

    Talking of Corals. Here are the exquisite, top of the range Coral Beta 10 ten inch drivers.



    And in their horn cabinets, with super tweeter.



    Not an easy build, but it can be done.

    Here are mine, built many years ago.



    102db sensitivity and superb sound! I should have kept them.

    Unfortunately, Coral drivers have been out of production for very many years.

    The nearest modern equivalent are the Fostex range. Have a look at this UK supplier, Wilmslow Audio, here: http://www.wilmslow-audio.co.uk/fostex-56-c.asp
    Mr. Tact!

    Main system: MMs/ADCs/Low output MC's/One rare Japanese SUT/One scarce British phono stage/various tonearms/hefty Japanese DD TT and hefty Japanese BD TT and small British BD TT. 4 CD players/2 jitter buster/2 DACs/Valve buffer. TVC stepped attenuator or valve pre-amp or solid state pre-amp. Current dumping power-amp or either of two Class A SS power-amp or Class A EL34 valve monos or big Japanese (part Class A) integrated. Big dual concentric speakers/Smaller dual concentric speakers/Two way British compacts and full range speakers, amongst others. And too much more to list!

    I would endorse full range designs. I have Magneplanars as my main speakers and Rogers LS3/5a speakers in storage. However, I can thoroughly endorse the full range speakers produced by this company: http://omegaloudspeakers.com/home.html

    They are a direct sell operation with the owner Louis being designer and manufacturer. The quality of construction is superb and the sound quality exceptional. I am on my second pair as a colleague begged to my the first pair I bought when I was working in Malawi. I bought the current pair direct from the Omega factory. They are a custom design (effectively the Super 7 monitor with an Alnico driver). The only criticism I have is that they take a long time to run-in.

    I understand that you cannot hear them before purchase, you are welcome to hear a demo of mine if you get back to the UK, but with your budget it would be worth having a break in New York and driving down to hear his speakers at the factory. He has a fantastic collection of vintage valve equipment to demo his products.

    In had a look at the omega site a few weeks back. Yes they are beautifully made - but customs would be bloody nightmare. I'll check them out again.

    One thing - I hate shouty, hard midrange - I've heard that wizzer cones can be troublesome in this area - or am I wrong....

    You are not wrong, ime.

    I've not heard the ones Geoff mentioned, so cannot say owt about them - but the several I have heard have been a sonic disaster.
    As I said, listen first - they may work for you, or they may not.
