Getting closer to pulling the trigger on the Walsh 2000s.
One question: I sent my room diagram and speaker selector form into John Strohbeen. He agreed that the 2000s would be sufficent for my room. However, he commented that since I was using subs, he would provide a sealed cabinet, instead of the standard vented one. He mentioned that this would allow for a smoother blend with the subs.
My subs are the Vandersteen 2Wq (a pair). These use an in-line, first order filter between the preamp and power amp. The roll-off starts at 80Hz, so the signal to the mains is down 6dB at 40Hz, 12dB at 20Hz. Vandersteen specifies that the mains must be reasonably flat down to 40Hz to use them with the 2Wq. The circuitry in the subwoofers compensates for this roll-off. My current speakers are Vandersteen 1Cs, which are vented. The blend I have now is completely seemless.
Bottom line: I think John's idea of using a sealed cabinet is based on the higher-order crossovers used by most subwoofers. My inclination is to insist on the standard, vented cabinet to maintain a robust response down to 40Hz. I think I will get the best blend this way. Also, I would imagine the efficiency of the 2000 would decrease if the cabinet were sealed and not vented. Although I have a pretty beefy amp, my room is large, and one major reason for the upgrade is to avoid the compression I get at louder levels from the Vandy 1Cs.
Thoughts, anyone?
