Thanks Sensi, 12,000 BTU is what my HVAC contractor recommended also.

A thought on the HVAC. The XPR's will put out some heat at idle because it is on but more than likely it won't be noticeable unless you put your hand near the unit and feel the temperature change. Now let's say at idle it makes no measurable affect on the temperature of the room because the room more than likely is big enough to disperse the minimal heat generated at idle.
Now crank it up and the XPR's will generate a little more heat, last night mine were 99 degrees after 3 hours of run time. The closet was in fact 5 degrees warmer than the room from the heat being generated by the amps. I have a VRF Split system in my house, I did not add to the system when I installed the Home Theater and I have no plans because the heat load being generated is not adding a significant load to the existing HVAC system.
I would recommend going with the test and learn theory in this case. Run the amps in the room and see if your heat load has any affect on the room temperature, if it is significant and you aren't comfortable then add the mini split system at this point. The beauty of the mini split is you can add it at anytime since it requires no duct work, only two copper lines and one control line from the outdoor unit to the indoor wall unit or if you get crazy put a flush mount ceiling cassette in for sleek sexy lines. Of course you still need to mount the controller on the wall which requires a single cable and power from the outdoor unit to your breaker box.
My two cents

Forget the Temperature. It is HEAT you should be concerned with. And minimally, at that, unless turning it UP. The XPA-5 apparently puts out the heat of a 75 watt lightbulb.

Hi, I'm trying to size a HVAC mini-split for my home theater room. Does anybody have numbers of how much heat the XPR-5 puts out at idle? I've got a stack of three for my active speakers. -Dave oh…. about 11……  |

Not to forget the amp in question uses about 75 watts while doing NOTHING but heating the room. Not really enough to worry about. At normal levels, you'll be lucky to get 50% out of it, efficiency wise. So, IF the power being used for music is ADDED to the idle power, you MIGHT get to the 100watt level in heat. This would be 5x10watts x 50%. = 25watts of additional heat. You're speakers are ALSO no more than 1% efficient (+- 0.5%) with speakers like 100db SENSITIVE (not efficient) running perhaps 2% or thereabouts. So, As it turns out, from PLUG to SPEAKER, maybe 99% of your input energy goes to heat. I'm sure that the INSIDE of your speakers can get pretty warm after a good, loud session. I'd recommend getting the FLIR ONE for either APPLE or ANDROID. www.flir.com/flirone/Thermal Imaging for the Masses. |

Sweet! I rented a Flir I7 once. Really fun toy (Uhh, I mean "tool") |
