I have a similar problem, 1 speaker in a corner next to AV rack , speakers 1.5 feet from back wall. My Bohlender Graebener 501's have a good soundstage and wide sweet spot, They do need about 200 hours break in, a large amp and a subwoofer. After the break in, bi-amped to a madrigal 7.1 amp, they do sing.
Speakers recommendations when placement is an issue
I could use some help with speaker recommendations-I am restricted to placement with speakers flanking a 6 foot built-in entertainment center and 1-2 feet from the back wall. Currently using Linn LP-12, PSE electronics, CAL Icon MK II. Want to start the upgrading process with floor-standing speakers, however, because of limited placement I don't want to waste money on Avalons or ProAc if I can't make them sing! Any speakers that can provide good sound in this setup? Budget is fairly open. thanks!
