Hi --
Just took delivery of a pair of Yamaha DBR10 powered speakers for the church. We intend to use them as floor monitors.
Soooo, before dropping them off, I had to try them at home with Genos.
Plugged in Genos and turned the input level up to 50% (12 o'clock). Wow! These speakers can get seriously loud. Dangerously loud in a small room...
The sound is clean and clear from top to bottom. I did a quick A/B test against the QSC K8 and would put both speakers in the same class. The DBR10 has a plastic enclosure vs. metal (K8). That should be OK in the church environment and would be OK in a home studio, too. They are roughly the size of the older (and discontinued) MSR100, but are far more powerful while being just as clean.
They won't replace the Mackie HR824 (mark I) monitors in my studio, but they will be more than adequate and welcome for our church ensembles (piano+guitar+synth and piano+2xguitar+bass+drums). They are a worthy, cheaper alternative to the DXR series.
I can't imagine people playing at these volumes at home, though, where studio monitors are enough.
Hope this helps someone out -- pj
