- Third, I cannot conceive your ELAC ports need a literal foot behind them. What diameter are those ports? A fellow loudspeaker engineer changed to Harman/JBL and among other things they were researching ports. IIRC you need 2-3 times the port diameter rear clearance. OK, maybe that is 6"? But now you could angle the speakers some, that will blast the air along the wall and the flow won't get restricted significantly. People worry about this way too much, it is only a possible problem at the highest volumes. Some inches of clearance plus toe-in, and it should be fine, don't worry about it. You could also stuff the speakers which would lower the port tuning and airflow speed. Or if you want to play REALLY loud you need a subwoofer!
- I'd try those ELACs right next to the bed, at the foot of the bed, a few inches out from the wall and then I'd play with the toe-in. Since you already have them, it costs you nothing but a little time to try this.
- Congrats on getting the Uni-Fi, I like the concept and the sound. Andrew is a very talented speaker engineer.
Thanks for the well-wishes! I turned 34 and the issues just started piling up... 35 will be better.
Good to know in-wall isn't verboten for exterior walls. I just measured the UB5 ports at about 2", depending on what part of the flare you measure. I think you're probably right, though, in that I should first try the path of least resistance--I only wish someone made mounts that come out a couple inches farther. I could cut and finish blocks from a 2x4 or sheets of MDF to mount the speaker mounts to, but this wouldn't change the distance of the centered port from the part of the speaker mount that screws into the wall... But like you said, it's probably not that big of a deal for this application, and toeing in will help.
To be honest, one of my surround UB5s in my main HT setup has about 2" from the wall. It sounds different from the opposing surround in tests, but not significantly, and if both of the UB5s I wall-mount sound 'different', they will still be more or less in sync with one another. Worst case scenario, I need to do some EQing.
I adore the Uni-Fi's, especially with a little help from Equalizer APO. I initially ordered B6s but was underwhelmed by the highs. For some reason, I took a chance on the Uni-Fis instead of exploring brands known for brightness, and I'm still very happy with them.
I'll try the UB5s. If they totally don't work, I'll try 225s and perhaps eventually Aria 906s...
