Which speakers will fill 5,000 cubic ft coherently


In porevious threads I've bemoaned the fact that my Kharma 3.2 FEs don't fill the room, 17 X 23 X 15 ft ceilings with a vertical enough soundstage, as though the speakers are literally too small. I have been advised to raise them,which I have done, , I have told to get taller, line arrays, even given names of custom speaker makers. Any specic recommendations from those that have had, and have conquered, this issue.

Thanks for giving feedback - I would only add that it might be wise NOT to modify the SP Techs or alternatively make sure you have a kit to make them standard again...just so that you keep your resale options open and also the option to move house or change their location in your house.
Shadorne, all the changes will be incorporated in the bass equalizer, an external box, placed between the amp and preamp. It wont affect the speaker design physically. Because it will be placed in the corner, almost, Bob will utilise this fact to reduce bass demand from the amps and other technicalities that are beyond me........
My friend, I had a room similar to yours with Kharma 3.2, and I struggled for exact the same reason.
