5,000 cub ft room (14w x 28d x 13h) that also opens to a staircase, entryway and kitchen.
Looking at Hsu CCB-8's which have 94 db sensitivity.
I sit about 12 feet from LCR.
Not sure if I need an amp, but price was reasonable.
Thanks for giving those details.
The CCB-8's are a nice choice. They're 94dB/2.83V/1m in half space
, so we need to dock them 3dB for direct comparison to speakers spec'd in full space/anechoic. 91dB/2.83V/1m is still above average sensitivity.
If you watch at Reference Level (calibrated 0.0dBMV), a CCB-8 will produce a theoretical maximum
at a 12ft seat with 20dB gain from the amp, which equates to a 100W burst
of power into 8Ω. This burst/dynamic power can be achieved by an amp rated for 50W continuous/Sine wave/"RMS" power (due to Sine waves having a 3dB crest factor), so can easily be produced by the 110WPC rated Marantz SR6012. If you "only" watch at -5.0dBMV, the required burst/dynamic power drops to one third of that: >30W
If you're cost conscious, even though the price of the Outlaw is reasonable, I'd suggest putting it on the back-burner and devoting the $600 towards another set of CCB-8's or even step up to PSA MT-110's for the LCR, which require 2.5x less power again to play any given level. Better overall results to be had there with speakers, rather than spending on rated power output that you may never tap into.
Hope that helps!
