The three double falcon cube array speakers that are used with the Acoustimass 7 system are designed to be connected directly to the corresponding Acoustimass module, and not a separate receiver/amplifier. While the connection may be possible, should they work, they will likely not sound as expected or desired to our standard.
However, the 301 V speakers could be directly connected to your receiver's "surround speakers" port instead. The 301 V speakers are rated as compatible with receivers that are 10-150 W per channel, 4-8 ohms. You are able to check with the manufacturer of your receiver to see if they are compatible.
