I have one pair of Aura 25w shakers that I want to add to a Kenwood HTB-354 (which does exist, despite the fact that it's nowhere to be found on the Kenwood site). It includes the VR-517 receiver, which looks to be pretty similar to the VR-506 currently on the Kenwood site. I'm wondering what would be the best way to go about adding the shakers. I really have no clue when it comes to power output, impedance, etc. The HTB-354 includes a 100-watt powered subwoofer, but I fear I would exceed the wattage limit by running the shakers through/off the subwoofer. I've seen a few posts here that suggest using a second receiver to power the shakers, but I'm wondering if an old stereo amp would be a cheaper (and space-saving) alternative. I've also seen suggestions that the shakers should be run in series, which I think means that the two shakers will be connected to each other and driven on the same channel. In that case, I would only need one additional channel capable of driving 50w (25 x 2) at 8 ohms, correct? Are there 50w mono amps/receivers out there? I'd like to do this as inexpensively as possible, considering that I had to go with an HTiB in the first place, and they're only shakers... Thanks in advance. ------------------ He obviously misinterpreted what it means to "be bullish."
