Speaker Selection with "difficult" room

A few thoughts....

You might want to go with a speaker with a soft dome tweeter (ie., a slightly rolled off top end). It will be tough for you to control the high frequencies in that room, so anything 'brightish' will be hard on the ears.

You definitely need a floor stander to fill the room, but I'd be inclined to re-look at the Onkyo, you'll need a tight grip on the bottom end to keep it in check. So maybe something with some really high quality power (100wpc+), and a fairly efficient speaker.

Tons of choices on specific brands, really a personal preference.

Will the speakers fire down the length of the room or across the width of the room? How far will you be sitting from your speakers? How loud do you listen?

I'm with Plato.

Anthem, TacT, Deqx, Lingdorf, or Audyssey are your main options for room correction electronics. Not neccessarily audiophile approved, but probably your best call.

You could also go with bass only correction from Velodyne or SVS/Audyssey if you're willing to go to a subwoofer. You'll just have to find a speaker with the right top end for all those reflective surfaces in your room.

Good Luck,

Speakers will fire down length of room (23 feet). 11 foot ceilings BTW.
The sitting areas are @8 and 14 ft from the wall that will be next to the speakers.
I don't know dB levels as far as loudness and if it translates to speakers but 60 dB is normal conversation and 100 dB is a mower so I would say between those levels and less. Thank you.

Joe22ny1,
Trying to get a handle on this room...
17' wide, 23' long. Speakers will be near one end with french windows on one side of the listening area and opens to a dining room on the other side of the listening area. Your seating position will be 8 ft in front of the speakers... Do I have this right? By the way average listening is typically 82 to 90 db. I find myself at around 86 or 87.
If this is correct and you want to keep your current receiver, you will need fairly sensitive speakers. I would suggest 90-91db 8 ohm speakers minimum. I would not risk 4 ohm speakers with this receiver... Next, if truly on a 5K budget. I would highly recommend you take
$1000 to $1500 toward a good integrated, then $2000 to $2500 on speakers and $500 to $1000 on a source and the balance on good cables....
If I have the room correct, We can give you some easy and inexpensive room treatments and make recommendations about speakers or electronics once we hear what you are dealing with. Tim
