Started work on a nice pair of these today. Excellent cabs and grills, with new surrounds and care on the drivers, will be near mint. Reserve now. RevolutionSounds@outlook.com. Thank you.

I picked up some great-looking 60’s vintage Allied cabinets a while back with nice 15″ woofers, a damaged crossover and two bad Jensen Sonodome tweeters. Wanted to get them working again, but didn’t want to drop a lot of cash on components, so the project kept getting pushed aside. Well, sometimes the Universe gives you a gift. The other day, I found a pair of beat up little Jensens at a thrift store for two bucks. Didn’t know what they had in them, but for the price… Turns out these ugly cabs held a pair of pristine, fully-functioning Sonodomes and nearly identical crossovers to the Allieds. Didn’t take long to decide to sacrifice the two-dollar Jensens for the greater good. Was even able to use the 10″ Jensen woofers to restore some solid Pressage 2-ways that had also been collecting dust. Coming soon. Cheers, ~L
According to designer Zilch (RIP), “eWave is a pre-engineered high-frequency ‘module’ for building 2-ways comprising an inexpensive compression driver, modern constant-directivity waveguide, and a crossover incorporating the requisite compensation. Mate it with any woofer and cabinet of your choice which will play competently through its 1.6 kHz crossover region. The builder is responsible for optimizing the lowpass filter for the specific combination they use; a generic one is suggested as a starting point, and many have found that to be adequate for constructing a successful project….”
Essentially, the eWave setup replaces the original crossover — and the old tweeters and midranges with a single, horn high-range driver — and brings high-end, modern sound to vintage cabinets with original woofers.
