I've listened to, but never owned, Magneplanars, Apogees, Bertagni Electroacoustics and Martin-Logans, but the closest I've been to listening to an OB speaker system is a pair of Infinity RS IIs --> three open-backed 5" midbass drivers plus a rear-facing EMIT tweeter, in addition to dual ten inch woofers and a front-facing EMIT.
Since I've been considering building a small OB system, I was wondering if anyone had any opinions concerning the sonic differences and similarities between the two systems. Also, why aren't there more commercially-available OB speaker systems (besides for example Jamo's "R" series), since it seems like:
1) the lack of a full enclosure would be an advantage as far as manufacturing and especially shipping costs (shipping is one of those "hidden" costs but is still a very significant portion of a speaker's street price).
2) building an OB would be much less expensive vs. a planar with its rather delicate and specialized radiating surfaces.
Thanks!
