    Default Interesting and actually Clever speaker design

    My audio bits: Thorens / diy phono, CD/dvd player(s), diy pre, F6, Tannoy Golds in my boxes / my xovers, and of course all strung together with basic diy Wires
    Lots of Cd's, yet more audio files, a couple of hundred semi worn Lps.

    We did exactly that a few years ago with a student - worked very well. There's not much point putting the port in the top section though.

    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!

    That's exactly what I thought when I saw the pictures.

    Yes, and I think they could be the cornerstone of a decent system.

    I have all sorts of ideas for speakers. I've built around fifty pairs in the past. One thought that keeps crossing my mind, is a minimal energy storage full range horn. Built using a wire frame covered in hard doped paper. The whole enclosure maybe weighing a couple of kilos without driver. It may sound daft, but the principle has been used successfuly in the past.
