Help with sub for music


Hi,

I have a CJ CAV tube integrated and QLN signature II's with external cross-overs.
I want to add a quality sub that will also allow me to run the speaker cables through the sub and cut off the low frequencies from my main speakers, which I'm hoping will lower power demand on the amp, and maybe improve the sound?
I looked at the Sunfire True sub, but they don't appear to have an option to wire main speakers through the sub, for low frequency cut-off?

Does anyone know a good sub that will allow me to do this? Is it a good thing to do in your opinion?

Can anyone recommend a site that explains options on how to connect a sub - the cabling must be some kind of 'Y' connector I'm guessing?

Sorry to have so many questions but this sub thing is driving me nuts. Its for music only, no stomping T-rex's in my house!

FYI and to clarify my post; the Vandersteen 2W crossover is external between the preamp and power amps. There are currently two model 2W. The 2Wq is tuned more for music, the V2W for movies. Originally there was just the 2W.
For your requirement your best bet is the Velodyne FSX-12ll. It will do what you want and has the famous Velodyne sound, accurate with low distortion. It's available new, I think for $799.
You have received good advice above. Vandersteen 2WQ or REL Strata III. Vandersteen makes passive first order filters. If you go with the REL you will have to make your own - not a difficult job. If you need guidance check Richard Hardesty at audioperfectionist.com
