I'm using Peavey SP2-XT in my living room, a predecessor model. Over your head is the right place, Peavey PA speakers project down. In this flyover state, the Peavey SP2-g (2001 or later) is the best speaker I've ever heard. I'm using about 1 to 2 watts of a 300 w rated speaker. Fortunately, the distortion charts show the SP2-G distorts less at room levels than at PA levels.
I haven't heard the PR10, they weren't in stock a the store the day I listened to the SP5 and SP2. I thought the 5's were light on bass for grand piano. I thought the 2's were okay on GP bass notes, and still do without a subwoofer. I miss the 32' organ stops, but oh well. Most LP's had those frequencies cut out anyway before 1980 to eliminate needle hopping. I admit I had to get help putting the SP2-XT's on the poles (speaker stands) above the Steinway piano; they are 94 pounds. Too much for me to lift above my chest level. Can't take them out in the yard for Fourth of July cannon shots (1812 overture), either.
If Radio Shack speakers sound good, they have really changed. I was always amazed at how good the specs on RS were, and how bad they sounded. A RS headphone amp brochure let out the secret. Headphone specs were +- 3 db 20-20000 cyc/sec. (this was in the seventies before hertz were invented). That should sound good. Not. Production tolerance was +-20 db. So any piece of ***** would have met the production tolerance, and these headphones qualified as that waste product.
I use grand piano tracks to audition audio equipment, since I know what that is supposed to sound like. If it sounds like a good one, thumbs up. I check time alignment of bass to treble with the drum hits on ZZ Top Afterburner, Woke up with Wood track. If the bass drum goes pow and not boog (with decreasing frequency sweep) then the time alignment is okay. something to do if you install a subwoofer, many such home assembled systems are not time aligned.
To get more opinions you might edit your title to "What about PR10's in home" or something. I don't usually even click on generic titles like "what do you thing", many other people won't either. (go advanced to edit the title). (it is probably too late, you only get 30 minutes to edit here).
Have fun.
