The Monoprice 5" studio monitors seem to be relabeled M-Audio BX5 (old version?)
So it seem Monoprice just bought them from the same factory that makes the BX5's for M-Audio.
I got the Monoprice 5" about 6 months ago, I was very content with the audio quality.
Tacoboy'M- Audio' speakers are NO more.
The Speaker line was sold - off to Monoprice, earlier in the Year !
You can " Google" It. If you care to "fact check". ;)
And I agree, These appear to be the same as the " old " M- Audio BX5.
