Does the amp wattage make a big difference?

~~~~Rwwear,

Would you please elaborate on the vertical bi-amping scheme of the Rs1's. This sounds like it may be very interesting! Thanks.

~~~~Rs1's do love the power! I presume you are to use this on the emim/emit panels. (The woofer towers must use their own amplifiers when using the servo/crossover system.) Personally 100 watts tube power per channel will play uncomfortably loud. 200 gets you there with less chance of frying the mylar from amplifier clipping. (Tubes are more forgiving than Solid State when they clip.) At up to $50 for an emit replacement and up to $200 for an emim (if you can find these), Weigh out the cost of retubing, replacing diaphragms, and the amount of listening you do. Only you can decide this. The placement of these speakers can also affect the perceived loudness of different frequencies, if it is an issue. What preamp are you using?

~~~~This is how I proceed with any amp connection to the Servo/Crossover: connect 1 inline 1 amp fuse (Quick Acting not Slow Blow) to each woofer tower.

If the amp inverts causing full power oscillation, the fuse opens in an instant. Once heard full power output from an amp, 330 w/ch. less than 1 second. This sound was so loud, everyone within 40 feet froze. If one could stand in front of a freight train horn while it was sounding in the listening room, then, one could appreciate the fuse set up! Ever see "Back to the Future" when Michael Fox turns up the huge amp and strums the strings of the guitar. That would be a good comparison.

The woofers were unharmed from the blast, owner had finger on power switch (advise well given by Beemers@ Audiogon). I suggested owner use a fused link next time.

Couldn't see any advantage of vertical biamping, been wrong before though.
