These are my third pair of speakers. The sit directly across from the tan sofa. Vintage, restored, Altec Lansing A7, VOTT's (Voice of the Theater) speakers, with JBL "Baby cheek's", 2404 super tweeters and custom crossovers. Custom crossovers are provided by ALK engineering. There is a commercial 15" passive horn loaded sub on the left side that is driven by a 1,600-Watt Crown amp. The sub is used with both the tower speakers and the vintage Altec A7's. When I gave all three systems playing, the two front towers are on my left (when seated) and the two rear towers are on my right, with the two Altec's in between them. The Altec's are typically driven by an all tube system (after the DAC with digital sources, using a separate preamplifier and power amp(s).
