About 8 yrs.ago, when I was looking for a someone that could recone or refoam woofers for some of the speakers that I was fixing and upgrading, I came across Loyd at Spectrum Sound. There was a totally different type of speaker that I had become interested in. I had first noticed them in a small speaker building book from the 60's, and I had noticed them being used behind the screen at a 70mm movie theater when Star Wars first came out. When I first started doing business with Loyd, I was amazed to find out that he was an authorized Altec servicer and had A7's in his home. I had always liked the sound of good horn speakers since I had discovered the sound of Klipsch back in the late 70's.
Nothing sounds as lifelike as a good horn system.
When I checked out the Altecs, they blew the Klipsch LaScala's away. When you get used to the dynamics of A7's, normal speakers just don't sound right. Thanks to Loyd at Spectrum Sound. He does all my reconing, refoaming, and he even puts together custom woofers for the systems I like to build. He is in St. Louis and is authorized for Altec and other brands.
