Monitor Audio GR20 or JM Lab 906

FWIW, I owned both the MA GR10 and the JMLab 906 at different times. The GR20 I heard in the store only. For my money, I preferred the 906; for its resolution of low level detail and higher frequencies and overall balance. However, my room is smaller than yours, and the GR20 will have substantially more bottom end. Some may prefer its weight in the lower mids and bass. Then again, if you intend to add a sub anyway...

Panderso,
Thanks for the input. The weight in the lower mids of the GR20 for HT is exactly why I liked the speaker(not to mention the 30% price reduction).

What if I dropped down a level to the Cobalt 816s?

Will a sub reproduce the low mids or will it be too low to accurately blend in these frequencies?

Thanks,

I'd be more enthused about recommending the Electra 926, which might be available at a good price, now that the 927 Be is out there. As you may know, the 926 got some pretty good reviews awhile back as a full range option.

I had the Cobalt 816 home for an audition before choosing the Electra 906. I did prefer the Cobalt to its rough equivalent in the MA line, the Silver S9i which I owned at the time. Recently, I upgraded to the 927 Be. I find the bass and mids more satisfying in the 3 way version of the Electra line, but, going by memory, the GR20s had more bass weight. I can't speak to sub integration; it's not something I've tried with my better speakers.
Good luck!
