Vertical bi-amp XLS 1500's

5 posts in this topic

Hi, I tried vertical bi-amping my Infinity Kappa 9's with 2 XLS 1500's. I used input Y mode, crossover at 83hz. Didn't work right, did I do something wrong? Input on channel 1 only. My third 1500 will power Kappa 7's conventionally.

Sound was garbled, they played at low level then amp shut down. Can this amp do a vertical biamp? As in one amp per speaker, ch. 1 to woofers, ch. 2 to mid/highs. In the FAQ above it says XLS series will not work in a bandpass setup. The way I read the user manual it should.

Unfortunately it will do high pass on one or both channels OR (not at the same time) low pass on one or two channels. So you if you want to biamp your speakers you can power the HF drivers with one amp and the LF drivers with another.
