They'll most likely be for a new system I'm building.

Horns will be Nagaoka D-58ES with Fostex FE208ES FRs (99dB/W/m) and T500A horn tweeters (102dB/W/m). Source to be predominantly a TD124 (if I can ever bag one - keep getting outbid at 3 in the morning!) or my current SCD-1. Dave Slagle autoformers to control the volume.
Room measures 5.4m x 4m x 3.1m; not massive but comfortable.

Jusbe,
Did you build the cabinets in the photo? Can you tell me about the wood you used? They look very nice. Is that a finished plywood or veneered MDF?
I've been thinking about building something similar (from the Fostex plans on the Madisound site).

  In fact, if you follow the link below, you'll find an example of a firm producing Tetsuo Nagaoka's designs.
  In general, many Japanese builders have been using Luaun plywood (apparently quite dense and heavy, and therefore well-suited to the task) to build these horns. 21mm thickness is 'de riguer'. The bottom plate of the horn is sectioned to allow a little tuning with lead ingots, or believe it or not, large pebbles! Personally, I like: a) the idea of being able to tune in this way; b) the relatively wide front baffle as a means of fleshing out the midrange; c) the use of a whizzerless FR driver (something is beginning to bug me about the acoustical cross over of my AERs - I hear it as I listen to the more expensive whizzered FR drivers, which are otherwise very appealing); d) the reliance on horn tweeters which, whilst detracting from point-source coherence, allow even more independent tuning; and e) even more tuning possibilities with Fostex P-16 HP diffractor plates.

Wow! - Ivan303 06:11:30 10/10/03 (1)
I bet it will sound fantastic.
Terry Cain was running the new TJ 45's in his Josh Stippich monoblocks at VSAC. The Cain & Cain Double Horns use a similar if not the same Fostex driver with a super tweeter of some sort.
Needless to say, the 45's drove the Double "Ben's" (Big E Nuff) without any difficulty.
Have fun!

  Thanks. Ron has still to hear from me though (should join the queue in the next 14 days), as I'm undecided on the wood base. And are the silver OPT's worth it? I don't know. You can buy a fair number of TJ 45's or records for the cost of the silver trannies.
  I think that Terry is using the new FE208 E-Sigma drivers, which were based in this limited edition version I've bagged. The version I'll receive is more sensitive by 2-3dB/W/m, so that's cheered me up a little.
  Bye for now.
