A:
Thanks for your question. The Direct/Reflecting cube speakers included with the Acoustimass 10 system are designed to connect to the outputs of the Acoustimass bass module (and not directly to a receiver/amplifier). The reason for this is that they are not full range speakers and the impedance would not properly match, which could cause damage.
You can, however, connect additional full range speakers directly to the receiver for more channels of audio. A few examples of full range speakers would be the Bose 161, 201 or 301 speakers. We hope this helps.
