Hi Shawarma, I read your question and thought I'd give my experience. I have two completes systems; the first is built around Altec Voice of the Theater components, the second is built around Theil CP3's. I prefer the sound of the VOT's. It's one of the best systems I've heard. 515B Woofer; 811B Sectorial horn; 802B hf driver; N-800-D crossover in an enclosure built to Altec's plans. They are efficient. The 15" woofers were reconed by Great Plains Audio. I can recommend them, they do excellent work. Talk to the folks at GP, they can build something for you from genuine Altec parts.
