MartinLogan Motion 15i vs. MartinLogan Motion 40i

MartinLogan Motion 15i Bookshelf Speaker
Reviews & Articles
Dimensions (H × W × D)
11.40” × 6.80” × 9.50”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.
MartinLogan Motion 40i Tower Speaker
Reviews & Articles
Dimensions (H × W × D)
42.50” × 7.60” × 12.80”1080 mm × 193 mm × 325 mm
The 40XTi fills the mid-sized slot of the three tower models in MartinLogan's Motion i series. This is still a fairly large speaker, with dual woofers and a frequency response down to 40Hz. Could be used standalone in a music setup, or with a subwoofer in a home theater to eke out every last bit of LFE information.

Notice: the above comparisons are based on the dimensions of a bounding rectangle that would fit the front face of a speaker, or in the case of volume, the measurements are based on a bounding cube that would fit the entire speaker. The measurements will not factor in individual differences such as curves or other variations in the speaker shape. Do not use these measurements as an estimate of the internal speaker volume.
