I second all of Kal's comments, except that according to this review the crossover unit includes a level adjustment provision, at least for the subwoofer. Won't that enable you to equalize the gains?

Recommendations for balancing gain in bi-amp setup

I certainly agree with the question--doesn't the crossover have have gain controls? If so, turn the upper-freq. level down or the lower-freq. level up. Kr4, re your #1, what the OP might need are amps with equal VOLTAGE GAIN and not equal sensitivity. The latter is almost always stated as Voltage required for rated output. One can calculate Voltage gain from stated sensitivity, but the 2 sensitivity numbers aren't usable by themselves. . |
Kr4, re your #1, what the OP might need are amps with equal VOLTAGE GAIN and not equal sensitivity.+1. Should have spotted that myself. If BOTH sensitivity and rated maximum power are the same for the two amps, then gains will be equal, to a reasonable approximation (assuming the specs are accurate and are defined in the usual manner). If those numbers are not both the same, gains may or may not be equal, and most likely will be different. Gain can be calculated from the other parameters, to a reasonable approximation, as described in my last post in this thread. Regards, -- Al |
Thanks for the suggestions posted. The crossover does have a gain control but at peak it offers 3db from what I've read. However, at the settings of 9 or above, the tight bass which makes these speakers great become boomy and clearly not flat. So I keep it at settings of 8 or below. I believe gain at that setting is 2db or less. Thus the resulting gain imbalance... I have many amps but none of the same brand or model. I have a multimeter, but would need tips on how to measure volt gain/sensitivity of my amp with this. Looks like the simplest route for now is to look into attenuation. Is there a formula for calculating the attenuation I will need to balance the voltage gains? Gerald |
