I was browsing speakers online today, and checked out the Orb Audio stuff. I thought it was rather strange that their Mod2 is just a pair of Mod1 speakers wired in parallel.
Say someone had a decent receiver, like an old Denon or Marantz, that is capable of handling 4 ohm loads on each channel. Say that person had a small surround system like Infinity TSS series or primus series, where they have all identical speakers for front, rear, and center. Could one simply add another one next to or on top of the center, Mod2 style, and increase the performance of the center?
