. Hi Dave, Apparently you don't have Vandersteen Speakers or Subwoofers. The reason one must have separates with Vandersteen Subwoofers or their Higher End Speakers is because the Vandersteen WX-2 or M5-HP is used to connect the output of the Pre-Amp to the input of the Amplifier. Vandersteen Subwoofers and Speakers with active Subwoofers don't use any thing like a Sub Out on a Pre-Amp or DSP which is why there is no drop out in frequency response as they are seamlessly integrated into the main speaker system additionally the subwoofer output is consistent with the output level of the mains without the issues of being too loud at lower volumes so that they are loud enough at higher speaker mains volumes again the volume is also seamless as it is controlled by the volume of the Pre-Amp going to the Mains! So no Dave, the Mains nor the Amplifiers are handling ANY low frequencies which is why it makes the Amplifiers and Main Speakers preform better because the Vandersteen Subs have their own dedicated 300 Watt builtin amplifier and the Speakers with builtin active subs have 400 watt amplifiers. I bought my first pair of Vandersteen Model 2 speakers from my next door neighbor in 1978 when his wife insisted that he had to sell his Vandersteen speakers before buying his new "Dream Speakers" so I have been familiar with Vandersteen Speakers for a long time. I used Vandersteen Subwoofers with Martin Logan CLS speakers and with both my Apogee Acoustic Caliper Signatures and Duetta Signatures to give those speakers some real bottom end as well as taking all the low bass frequencies off of them. I currently have a pair of Vandersteen Model 3A Signature speakers with two Vandersteen Subwoofers (sounds fantastic for the money) and a pair of Quatro Wood CT speakers that have the builtin powered subwoofer. . *iPhone* Media Room: ModWright Platinum Signature Transporter, VTL TL-6.5 Signature Pre-Amp, Ayre MX-R Mono's, VeraStarr 6.4SE 6-channel Amp, Vandersteen Speakers: Quatro Wood Mains, VCC-5 Reference Center, four VSM-1 Signatures, Video: Runco RS 900 CineWide AutoScope 2.35:1, Vandersteen V2W Subwoofer Living Room: Transporter, ADCOM GTP-870HD, Cinepro 3K6SE III Gold, Vandersteen Model 3A Signature, Two 2Wq subs, VCC-2, Two VSM-1 Office: Touch with Vandersteen VSM-1s Kitchen: Touch in-wall mount w/ Thiel Powerpoint 1.2s Bedroom: Squeezebox BOOM Bathroom: Squeezebox Radio Around the House: SliMP3, SB1, SB2, SB3 Ford Thunderbird: SB Touch, USB drive Ford Expedition: SB Touch, USB drive ------------------------------------------------------------------------ iPhone's Profile: http://forums.slimdevices.com/member.php?userid=13622 View this thread: http://forums.slimdevices.com/showthread.php?t=108865 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
