Sorry to revive an old thread, but it was a very interesting read.
I own Vandersteen Treo CT’s and one (currently) Rythmik F12 subwoofer. My preamp is an NAD 12 and the Treo’s are being driven by Rogue M-180 monoblocks.
After reading this thread, I believe I understand the benefits and design of the Vandersteen subwoofers. The main benefit is the crossover relieving the main speakers speakers from playing low frequencies that they might not designed to play. This also helps the amplifiers by “freeing them up” to do more.
My question is: If I use a stereo preamp (NAD M12) that can control the low pass filter AND the high pass filter, would I see much improvement using a Vandersteen subwoofer over a Rythmik (or any quality subwoofer)? Also, what would be the best crossover settings on the NAD with the Treo’s?
I do plan to add a second Rythmik F12 subwoofer soon. The NAD can control two subwoofer’s in either dual mono or dual stereo.
P.S.- I am in no way saying that Rythmik subwoofers are better (or equal to) Vandersteen subwoofers. It’s just that I already have a Rythmik and adding a second on down the road will be easier (cheaper) than buying two Vandersteen subs.
