Help with HT Design Priorities

[diesel_88]

Nearly all of the HT designs I've found are optimized for a distinct listening position. What if you don't HAVE a listening position? Every comfy spot in my living room gets used during movie night. My wife likes to re-arrange the room, and frequently sets up the TV catty-corner (where the heck do I put the surrounds?!). She decorates beautifully and I fully support all that, so I want to build a system which sounds decent from all over the room rather than excellent from one spot.

I'm looking for some help on design priorities. Here's what I've got so far:

- Main speakers with little to no beaming, meaning relatively small woofers and/or low crossover points.

- Wide-dispersion center channel--I listen up to 45 degrees off-axis. For WAF, a horizontal speaker is preferred. D'Appolito? I've read about the "quasi-spherical" distribution, but most MTM designs I see don't have the 3rd order Butterworth I thought that required.

- Monopole surrounds, high on the wall, pointed at the ceiling (per Dickason's suggestions in the LDC) since I don't have a "sweet spot" away from which to aim the surrounds.

Am close to the right track? What have others of you done in similar situations?

diesel, you might want to try GR research's a/v-1rs. it is supposed to have very good dispersion so may give a wide range of seating options. email danny and see what he says about using it as a main.

Home theater? Wide dispersion and sweet spot??
..Seems to me like constant directivity would be the best solution.

Duh!

Design the center as a 3 way WMTW as it results in much better horizontal off axis response than an MTM. You get the form factor and increase sensitivity of dual woofers along with the horizontal off axis benefits of an MT.

"Constant directivity" is my vocabulary word for the day; haven't run into that term before. If it means "sounds the same off-axis as on-axis," then yes- constantify my directiviosity!

That's what I'm after in a surround, but I hadn't thought about using it as a main speaker. Do you mean mounted in its intended position, bouncing off the ceiling? Lemme think on that...thanks!
