Thanks for the opportunity to compare speakers, eat pizza and become drenched in dog slobber.
The Sonance Cinema Select Cabinet and Rocket RS250 MkII sounded remarkably similar in your room.
Although I haven't compared the Rockets and Sonance speakers directly in my room, I have compared each with my Boston Acoustics A100x speakers. I think there is more of a difference between the Rockets and Sonance speakers in my room, my preference being the Sonance.
The differences in room acoustics, speaker positions, speaker frequency response, receiver crossovers and subwoofer equalization may explain my preference. In your room the Rockets did not have the somewhat bloated bass that I heard in my smaller room.
I noticed the Sonance (with silk dome tweeter) has better off-axis response than the Rocket (with ring tweeter), but the difference was only apparent at wide angles, greater than 30 degrees.
Test conditions in sajohnon33's room:
* Each pair of speakers was powered by an identical pair of Mackie FR-2500 amps.
* Sound pressure levels were matched.
* Yamaha HTR-5250 receiver was used as a pre-amp/processor, speakers set to small. I believe the Yamaha's crossover is 90 Hz and the slope may also differ from THX specification (3rd order low pass?).
* Bass was directed to my Boston Acoustics PV-800 subwoofer.
Differences between tests in my room and yours:
* Room acoustics.
* Crossover: My Onkyo TX-DS898 has the THX specified crossover of 80 Hz, 12 dB/octave high pass, 24 dB/octave low pass.
* No equalization was applied to the subwoofer in your room; the subwoofer is equalized in my room.
In your room I didn't hear the tight bass and low end imaging from either speaker that I hear in my room with the Sonance. For example, "They Never Really Wake Up" by Viva Voce, the bass guitar has a remarkable center image and smooth, even response in my room. The center image of the bass guitar was lacking in your room.
We didn't have time to equalize my Boston Acoustics PV-800 subwoofer for your room; I think that may be part of the problem. The subwoofer is equalized with a Behringer Feedback Destroyer and Real Time Analyzer in my room. The Yamaha's crossover may also be a factor.
The speakers sounded good, but you can look forward to better bass when you upgrade your subwoofer and equalize it.
