The Monitor Audio Bronze B2 (or BR2) is a 2-way bookshelf speaker featuring a 1" gold C-CAM tweeter and a 6.5" C-CAM woofer, delivering 30-100W power handling, 90dB sensitivity, and 8-ohm impedance, with a frequency response of 42Hz-30kHz, known for clear detail and punchy bass from its ported design with HiVe technology, suited for shelf or stand mounting with bi-wire terminals. I found them to be exceptionally good sounding. This pair is in like new condition. Matched pair from factory with identical serial nbrs. If I didn't have several other high quality bookshelf speakers, I'd be very happy to keep these as my primary speakers. Please send your phone number via craigslist email, I'll call to arrange meeting. I can meet a PHX buyer in Picacho Peak area.
