Hi Freddyi
I did rebuild one probably 12 years ago and was very pleased with the results and measurements. What i recall was that the mod version using a JBL2226 and BMS 4550 had a couple db greater sensitivity and about an octave extension at both ends and did not exhibit crossover phase shift using a synergy horn type crossover. My plan was to write an internet how to project at some point but i never got around to it.
It did require some physical mods but they were simple and the horn was set back an inch or so.
If you have an a-7 and want to try, i will dig it up, pix and info got to be somewhere around here, hopefully on a hard drive in a computer that still works haha
Take care
Tom
hey Tom
I don't have an A7 (do have 416/811/511, 806 components) - there's others on this forum itching to hear how you accomplished this feat.
I'd love to hear it. The only time I heard an A7 was around 1972 - just one in a local Hifi store - it was mid-centered, no highs and not much bass - it was only about 10 feet away and driven by whatever solid state amp hooked up.
would your network work with a direct radiator 15" ? - how about a horn on top of a Karlson?
BEST,
Freddy
