GEs produce incredible bass because of the built in powered woofers but fall short in midrange tone, timbre and transparency. They are also highly directional with limited sweet spot. Can be "flat" sounding with jazz and horns.
The PSBs are bass heavy and the bass becomes overdone as they age. Midrange can be glaring but the treble and dynamics are excellent.
Heard 'em all and chose the Spendors. Glad I did.
