You can easily verify what I mean. Get the driver's T/S parameter, put together a WinISD model (use sealed box with the volume you intend to use if you intend to use box, or say 2cu ft to simulate a sealed door). Almost certainly you will see the driver running out of excursion with 150-200watts of power per side at low frequencies.  This is why there aren't many high power full range 2-channel amplifier. If you want something cheap, PPI P600.2 is probably the best in its price range. Boston Acoustics gives 2x300watt channels at 4ohm, if you can still find them.</p></blockquote><p></p>
