Select two speakers:
MartinLogan Motion 15i vs. Polk Audio T15
MartinLogan Motion 15i Bookshelf Speaker
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.
Polk Audio T15 Bookshelf Speakers
Good bang for the buck, but as standalone bookshelf speakers, some may find the T15 somewhat hot on the high end and lacking in deep bass. These are probably best suited as rear-channel speakers in a home-theater setup with T50s as your right and left speakers.
- The front face of the MartinLogan Motion 15i is approximately 12.19% larger than that of the Polk Audio T15.
- The depth of the MartinLogan Motion 15i is approximately 31.03% deeper than that of the Polk Audio T15.
- The spatial volume of the MartinLogan Motion 15i is approximately 47.01% greater than that of the Polk Audio T15.
Please Note: 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 comparisons 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.
