I'm kinda surprised Altec used such a large horn for a residential speaker system. They always seemed a little harsh- tinny. Back in the 70s, everyone had a garage band. We built our own A-7s bc we couldn't afford them. Wd got the dimensions from those speakers at a local music store. I remember heating up the plywood to bend for the bass horn. We bi- amped the systems with the electronic crossover of the day, and drove them with Crown amps. This stuff was bullet proof when we were done! Huge cabinets, really heavy, moving from gig to gig, what a hassle! It was fun times back then! Your reconstruction is really cool. Love those baffles! Never seen that before. On the horns to reduce the ringing, or tinny sound, I recently had to replace diaphragms in a pair of Peavey speakers of similar design, and they use aluminum horns, not sectioned, with a black rubbery material stuck to the outter surfaces. I wonder if car undercoating would work, or bed liner? Bed liner works great for an exterior finish on professional, stage speakers. Really can take a beating. Love both your channels! Getting ready to fill a new aquarium. Thanks!!
On my Klipsch Epic Cf3, with plastic 10x8 horn, I used a 3m coban medical soft wrap, many lightly applied layers, then sprayed on a rubber coating. Also installed the Crites titanium tweeters shortly after. Much smoother and succinct. 5 wpc tube 200 wpc SS was not harsh anymore. Oh and then damping and bracing the cabinets… 🔈
