I purchased a set of BG 72″ ribbons quite some time ago.  I listened to them, but ended up putting them in storage as I didn’t have enough room.

Now I am in a new house with a dedicated media room.  supporting equipment are a Musical Fidelity CD-PRE, a Musical Fidelity A3cr (for ribbons), an Anthem M20 (for bass), and a dbx 223 electronic crossover (set to 250 Hz).

The ribbons aren’t full range, so add to them four 15″ woofers per side in an unbaffled arrangement.
