Thanks everybody for the list so far. Here is my contribution: - Bboom, Thrak, King Crimson - Anything from Depeche Mode - Lady Marmalade, Moulin Rouge soundtrack - Anything from Tool - 1812 Overture, Telarc, cannon shots Actually, I have been amazed at the amount of low bass information in most of my music, CD or cassette tape (Nakamichi ZX-7). It's like getting a whole new collection! BTW, I am running the (1) VMPS Larger with the 2 passive crossovers, one crossover for each active carbon driver. I have my Chorus speakers connected to the high pass (90hz) from the crossover and the mains level potentiometer turned down all the way (-4dB cut). I actually have found the level match between the VMPS and the Chorus speakers to be about right. My Adcom GFA-535 can hit about 102dB (at the listening position) on bass rich music before clipping. This is loud enough for me. Some day I will try biamping and an electronic crossover, but I am extremely happy with the system as it stands now.

Now that I have my VMPS larger subwoofer integrated with my Chorus speakers, I would love to know what your favorite CDs are that have low bass information. Scott ------------------ Definition of an idiot: Noun; Someone who doesn't know something you learned yesterday.

The factory lists the Chorus efficiency at 101dB. The Stereo Review article tested them at 96dB if I remember correctly. Scott ------------------ Definition of an idiot: Noun; Someone who doesn't know something you learned yesterday.

Ray, Thanks for your reply. I have the VMPS ordered. I am going to try the GFA-535 for the time being. I should be able to determine amplifier performance by monitoring the clipping indicators on the amp. If more power is indicated, then I will start shoppong on eBay. I have the perfect spot in my room and wife approval! For the others who do not know, the VMPS Larger is 23x32x19" (HxWxD). It is -3dB at 17hz, 92dB sensitivity. It is a passive subwoofer that I will initially be running with 2 VMPS passive crossovers with a 90hz low pass. It has a 12" and a 15" active drivers and a 15" passive radiator in a BIG cabinet. No denying the laws of physics here! I ordered it with the Mega woofer option which means that the 12 and 15" drivers will be the carbon fiber drivers with stacked magnets. This increases power handling and reduces the -3dB point to 15hz. Scott ------------------ Definition of an idiot: Noun; Someone who doesn't know something you learned yesterday.

I am finally planning on adding a subwoofer to my system. Here are the details: -Klipsch Chorus Mains (96dB sensitivity) -(1) VMPS Larger Subwoofer w/ carbon fiber woofer option (92dB sensitivity) -16x17x8' room -Initial hookup will be biamped using the VMPS passive crossovers in lowpass mode only (90 Hz and below) with the mains receiving a full range signal. -Future hookup might be biamped with an active crossover. -Current amps would be an Adcom GFA-535 at 60W/channel for the L and R of the 1 subwoofer. An old 70's Sony integrated at 30 W/channel would be used for the Chorus mains. Hookup will be run through my Carver C1 preamp; preamp out 1 to the Adcom/VMPS and preamp out 2 would go to a high level input on the Sony integrated/Chorus. Using the Sony in this way will allow for volume control of the Chorus in order to match downward their level to the less efficient VMPS. What do you think, will this work? I would appreciate comments about this proposed setup. Also, do I have enough amp power for what I am trying to do? FYI, I rarely listen at levels higher than 100dB at ~12' from the speakers. The VMPS Larger subwoofer is listed as -3dB at 17 Hz. Scott ------------------ Definition of an idiot: Noun; Someone who doesn't know something you learned yesterday.

tblasing, I have a Carver C-1 that I bought on eBay last year. Once I discovered the "efficiency" problem, I had my local repair shop do the -9dB attenuation mod on the first preamp outputs. The mod was inexpensive and greatly improved the "control" ability of the volume knob. FYI.

I would recommend Caig Labs DeOxit and ProGold for the corroded RCA's. A couple of treatments should clean them up like new. www.caig.com Scott ------------------ Definition of an idiot: Noun; Someone who doesn't know something you learned yesterday.
