That is the model number, good luck finding a bunch of info on the sub on-line. I had to call eclipse directly to get the T/S specs, which I still have if you want them, but basically the sub is a, svc 4 ohm, 250w rms, 500w max, released in 2000 so it's still when Eclipse stuff was good. I bought the sub from a car audio shop that had it on display in a case, it had never been mounted or powered. I built the enclosure at 2.5ft3 sealed for ext bass, kinda like a sealed enclosure that plays nice and low but also has a nice bump in output at 38-40 hz like a ported, sounds good. Like I said if you need the theile small specs I can get those for you too
