Have you ever heard anything to make you think you need more capability up there? If not, that means I could probably get away with 4" concentrics for height at the volume levels I listen. That makes going from 7.1 to 7.1.4 channel much more practicable...
Yes, it is quite noticeable. Especially with the Emo surrounds as heights. Realistically a near 20dB gap in overall sensitivity from front mains to the Emo overheads. Yes, there have been several times when I have nearly overloaded them with overhead content that was of high level. Some people think that the heights/overheads don't get much of strong signals but they do and these speaker locations should be treated like every other speaker in the system. Should be noted that I have never overloaded them in the past listening at or near reference levels when used as conventional surrounds. Also, I cross them at 80hz like the rest. I could probably get less distortion from them in these events if I pushed that higher but I like to keep this crossover as a global setting. Things sound more alike that way to me.
I've been planning on relocating the front pair of overhead speakers. They are physically the furthest speaker from the MLP yet they are the least sensitive. I mounted them as such because it was easy. It will require some new light construction to mount them where I'd prefer them to be but this will allow me to drop their levels down 4-5dB and that should be enough to stop them from being overloaded from time to time, I think.
I'm only using them because they are free as I already owned them.
At some point I'd like to upgrade ALL of the surrounds and overheads to identical speakers. Not sure what I'll do. The cheapest route would be another pair of JBL 8330's (have a third pair in storage) and just use those too but they are pretty heavy. Was thinking eight Volt10's would be cool and not too expensive relatively.
So to answer your question, you might be able to get away with 4" KEF's but I'd probably cross them a bit higher. Which in your case might be alright because you usually have high quality, low inductance-type subs all over. Not super sure about reference with those but for 99% of the time and at sane levels...I think you would be alright.
My JBL 8330's seem to hang just fine. They are very
close to the seats though so that helps a lot.
