I have just bought a pair of Jericho Horns with fostex FF225K, what suitable amplifiers would you recommend for them? Its a small room so only really need a few watts, i guess Valves are the way forward?
Any particular type of amps to look out for for under £500?

An externally hosted image should be here but it was not working when we last tested it.

Got a close-up of the triangular baffle treatment?
An SE valve amp with highish output impedance would likely be ideal.

Looks like a novel, and probably effective, use of circular felt gliders cut in quarters. I've cut those up before to strecth them for under stuff, but this is some good lateral thinking. A couple different sizes and a biy more qork and you could build serpinski triangles. How do you like them?

First listen today, can only compare with the little ATC SCM-7's in the pic really. From what i remember of the Veravox 5S drivers i had in BiB's, the 225's have more dynamics and 'neater' treble. I cant get over how smooth the 225's are!
Compared to the ATC's, main difference is dynamics and punch, lots of attack and treble energy with electronic music. They seem a little closed in and not as vocal orientated as the Omnes Audio L8 (but they were in OB).
Bass is ok, a bit hit and miss, the ATC's have a very even bass response, the Jericho's seem to go a little lower, but have better punch.
Its a less than ideal amp (Teac SS made by Thule) but does not sound too bright. 🙂

The 225k is indeed a sweetheart of a driver. I rather liked a fostex FT7RP above it. I had great results with a Fi Super-X 2A3 amp
if you don't mind a DIY/kit amp, the first 2 that come to mind are Bottlehead Stereomour (2A3)

your choice from a wide range of driver / output types, but not as "complete" a kit in terms of parts included, chassis, etc., as the Bottlehead products

I'd suggest going with 4+W amplifier. 1W is enough for high volume (~90-95dB) if you are at 2meters (6.5feet) but it is always good to have reserve. Still, if you don't listen loud, 1.6-2W will be enough.
Sorry for being offtopic ....
Congrats!
I like the way these (white!) look and the EnABL treatment is nice 😀 Maybe you should think about something prettier for the super tweeter .... a box or something?
Would you please give more comments about the Fostex horn vs ATC speakers?
Thank you in advance!

I summed up a quick comparison above, not done an A-B test yet. The Jericho's certainly sound a lot better at lower volumes 🙂
Just out of interest, are there any other decent designs for the FF225K? Can only really find the Jericho, BiB and the recommended fostex one....
I'm once again rather offtopic .... I cannot recommend any other designs, but as you have this one built already, another one will have to be much better to be worth it making it - and I guess there will be no such one.
