The CRM-2BIP is the only on-wall ribbon bi-pole available and features a long list of true, XT Series performance features. it’s a purpose-built, on-wall surround speaker that’s a perfect timbre match to any model in the existing Cinema Ribbon line. It’s also the only bi-pole speaker on the market to feature the benefits of dual, side-firing ribbons. At 400 watts per cabinet, the deliberate location of each pair of these high output ribbons create the wide “diffused” rear sound stage.
