Read my review of them at Dagogo.com
The AHB2 is far superior in Mono mode, no comparison. YMMV
Work with the power cord on the Legacy Wavelet; it will make a difference. Also, the quality of the XLR cables used for the bass section will likewise make a difference. I have had many experiences with Legacy speakers in such matters (reviews), so you may trust my guidance. I am not interested in debating my recommendations.
