These were built several years ago, but I’m still really pleased with both the look and the sound. At the time I wasn’t into woodworking, so I designed the cabinets and had them built from MDF by a local cabinet maker, then hired the paint job…that’s faux wood on the sides and base.
This is a proprietary design that I developed over a period of 7 years (I’ve designed about 9 models, of which I built and sold a couple hundred pairs under the name of Sterling Acoustics…these are by far my favorite set). The basic cabinet is an 8’ folding transmission line for the 8” Focal kevlar long throw woofer, the 5-1/4” mid is also a Focal kevlar driver that’s in an aperiodic chamber that vents into the T-line. The tweeter is a dual chamber Seas aluminum dome. The crossover is passive, using some unique poly capacitors that are made specifically for Convergent Audio Technology’s “CAT” preamps and amplifiers. The inductors are heptalitz air core, and the internal wire is Kimber Kable. Each driver has it’s own input terminal… the drivers are currently tri-wired with some very average basic OFC 14 awg speaker wire but were wired with Kimber Kable once upon a time at our other house….they can also be tri-amped. For a number of years now they’ve been hooked up to a Lazarus Cascade Basic tube preamp, and a pair of modified Dynaco Stereo 70 tube amps that were converted into triode mono blocks. At only 17 watts per channel (less than 1/10th the power output of some of my other amps…Hafler DH500
255wpc, NYAL Moscode 300 150wpc, Distech LS-2 @ 105 wpc), they’re the sweetest sounding amps I’ve owned. Ironically, about the time my “poor man’s” highend system was really coming together and sounded amazing, we were at the stage in our lives when the primary music in the house was Alvin and the Chip Monks, Raffi, and the Muppets! Now that the kids are bigger, I’m 49 and I’m certain my high frequency hearing is no where near as sensitive as when I built these. The system now sits largely neglected and is no longer optimized for the room, and gets used mainly for Christmas music, but was once a very nice sounding setup with these speakers…the potential is still there, but I suppose I lack the motivation or desire to do anything about it right now.
