The A5+ Wireless uses the same amplifier design and woofers that the original A5+ does, so sonically both the A5+ and the A5 should sound virtually the same. The biggest difference between the two is the added Bluetooth receiver built into the A5+ Wireless; we’ve added a 24-bit DAC built inside that connects any bluetooth capable device (whether be your phone, tablet, or computer) to the speakers and streams high quality music. Cosmetically, we’ve centered the tweeter as opposed to the off center tweeter design of the original A5+s.
