It sounds like this will be primarily used for HT?
If so, I feel I should warn you.
I have Klipsch RF-82 ii's for my HT and other brands of speakers for music. The reason is that I find the Klipsch make great HT speakers.
All speaker designs involve trade-offs. For the Klipsch, playing music, the con is there is always a bit of effect from the horn that doesn't sound quite right. Careful adjustment of toe-in can get it pretty good, but there is always a slight sense of some sounds (mainly attacks of notes like hard consonants in vocals) being "cast" to you while the softer sounds are farther away. For HT, this is great - impactful on hits (the sub makes the hit solid, but it is high frequencies that give the sound their immediacy), easy speech intelligibility, and hearing the delicate "pin drop" in that suspenseful moment benefit from this effect! The "con" aspect of this gets lost to the excitement Klipsch brings to HT. They also do well with hard Rock and Metal where the music does not require a pristine acoustic reality - the slap note of a bass guitar or plucking of regular guitar strings benefit from this immediacy.
So, IMHO, Klipsch speakers perform "above their pay-grade" as a HT speaker. You have to pay a lot more money to get this effect from speakers that also does acoustic music well. I use a rim shot on a snare as my primary litmus test for speed of attacks and the "Klipsch horn trickery" gains an effect that I have to pay 3 times as much to get similar out of non-horn speakers.
I don't know how much of this is Klipsch and how much is horn!
If you have a chance to listen to some nice speakers at audio stores, you might want to verify that your Klipsch have not "imprinted" too heavily on you such that other speakers don't engage you as well.
But to recapitulate my main point, while there are certainly better (by standard criteria) DIY speakers than your Klipsch, the Klipsch shine particularly bright in a HT setting.
HTH and good luck!
