A midsized rear-ported bookshelf, featuring a 5.25” low-frequency transducer and a folded motion high frequency transducer, which MartinLogan claims replicates much of the performance of their high-end elecrostatic speakers. May need to be paired with a subwoofer if sub-60Hz bass is a priority.

The Klipsch R-120SW sub is exceptional in its low-end frequency response, going down to 29 Hz. This is low enough to provide movie sound effects that can be felt in your chest, but the remainder of the frequency curve is fairly well-controlled, free of excessive boominess, making it a good choice for music listening as well.
