290 mm × 173 mm × 241 mm

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.

A center-channel speaker with commanding low-end presence. The 50XTi pairs perfectly with MartinLogan 60XTi towers, but holds its own with a frequency response down to 50Hz. Features two 6.5” woofers and MartinLogan’s signature folded tweeter to provide excellent imaging and presence on the high end.

Note: the above comparisons are based on the dimensions of a bounding rectangle that would fit the front face of a speaker.

These measurements do not take into account variations in the speaker shape, such as curves, diagonal edges, or cutaways. These measurements cannot be relied upon to measure the internal volume of the speaker.
