What is your opinion on the SQ of the HTM-12? Is it loud, flat sounding, what?
I presume you are looking at the HTM-10 as surrounds?
Thank you for the kind words.
You can read my first impressions here. Cam Man's HTM-12 Build
Since posting that, I've measured a bit and discovered that they are very admirably smooth (close mic). Acoustic measurements averaged in listening area reveal that my screen wall installation imposes the need for a modest amount of EQ work. That is only in the region of below about 175Hz (boundary gain acoustic influence). The right one has more wall around it than the left, so it is a bit tubby in that region, but not terrible. Unfortunately, I can't get my aging AVC to communicate with the Audyssey Pro utility in my laptop any more, so an AVC upgrade is going to have to come. Whether that will be an Audyssey or DiracLive capable unit is up in the air. I will wait on that until I see the MultEQ Editor mobile app that is coming out next month.
You are asking for a more subjective impression. I find the HTM-12 superb. I would call it capable of very refined nuance, yet brute force impact. Very smooth and transparent, yet a sleeping giant on dynamics. I am not a fan of full-range (running in full-range) for any speaker unless the speaker is large AND in a nominal location for acoustic LF response. Since that is always a wild card, I always run with bass management (crossing to subs between 60Hz and 80Hz) with the subs in locations friendly to good acoustic LF response. The close mic measurement showed them -3dB at 80Hz...which is ideal for such! I am also very impressed with its smooth coverage/dispersion.
The HTM-10s are being considered for a smaller room.
We had our adult kids over for dinner the other night, and we watched the Eagles Melbourne Farewell concert BD for the first time in a long time. We ran in PCM stereo with Dolby Surround post processing rather than 5.1 which kept more sound up on the LCRs. Incredible! Where these type of speakers really shine on that type of material is in dynamic attack; snare drum strikes, etc.. Even a kick drum has spectral content well above 60Hz. If speakers can't faithfully recreate that attack, then the impact of the kick drum is not recreated as well.
By the way...effortless performance at Reference level, even with 30 guests in the room (Super Bowl half time). Loud without harshness. 150wpc separate amp.
I highly endorse the HTM-12, although room size and throw distance should dictate whether HTM-12 or HTM-10.
