Hello im brian from southern indiana. Im a long time fan of altecs and horn speakers. Heard model 19s as a kid hooked from then on. Wanting to build some altec 2 ways using altec and gpa parts and pieces. I have just grabbed some 511b horns. Was wanting a 19 clone so I may have to get some 811s. Im wanting to get my learn on and while I've been listening to music for 40 years on some decent gear this would be a first trying to get some speakers together so please help the slow kid when I hit you with questions!:} Thanks in advance.
