    I wondered if it didn't maybe have something to do with that.

    Impressive that it can handle 2 ohm loads per channel. I watched the video and it looks like it can really do a lot to create a smooth frequency response in the room.

    Here's a devious thought: Wouldn't it be interesting to randomly take a 12" woofer, 5" midrange and 1" dome tweeter, throw them in a correctly designed (for the woofer) box, and just wire it up to one of PE's off-the-shelf, premade crossovers... and see how close to a flat frequency response this thing can create.

    Also, Is it odd that the bridged output would tap into the L and R positive leads? I'm used to seeing a + Positive from one channel and a - Negative from the other channel.

    EDIT: I see the Crown Pro amps use this configuration also. Wrong again, as usual.

    It looks like the 560wattx2 power-rating is at 2ohms:
    -"The two amplified channels can power 2 ohm, 4 ohm, and 8 ohm speakers in stereo and can be bridged to power 4 ohm speakers at 1150 watts."

    It also claims 501watts RMS/[email protected]

    Also claims 0.74% THD+N @ "rated" power.


    Is that 8ohm/stereo wattage claim a typo?

    Well, like many of their other offerings, the power rating could be more than a bit optimistic, and with a price tag North of $700, it already feels a bit pricey for PE.

    Yeah, it was kind of an "If I didn't care about money" thought. I'd also like to see less powerful versions for cheaper prices, since mids and highs do not require the power the lows or subs do in a true multi-way setup.

    Stack 3 of them ... at $750??? Nope. Not me! I'll scour the sale adds for a reputable brand amp and head over to minidsp for the processing.

    Yup. Where's our PE reps to tag... this spec sheet is really inadequate for DIY Audio nerds

    Hopefully an update is in the works for later.

    Yeah- stable to what impedance loads? Impedance is NOT EVEN MENTIONED!!

    Just saw this in the email blast today:

    Potentially very nice! Stack 3 of those for an active 3 way hell of a system! Pretty expensive though, and a lack of amplifier specifications is annoying.

    Who has Right Mark Audio Analyzer and can volunteer to measure one of these things at 1W?
