Select two speakers:
MartinLogan Motion 15i vs. MartinLogan Motion 4i
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.
MartinLogan Motion 4i Bookshelf Speakers
Inspired by MartinLogan’s ultra-high-end electrostatic loudspeakers, the Motion 4i’s are often used as bookshelf speakers or front R and L channels in a surround setup. With a frequency response down to 70hz, they deliver a large speaker sound in a small package.
- The front face of the MartinLogan Motion 15i is approximately 9.86% larger than that of the MartinLogan Motion 4i.
- The depth of the MartinLogan Motion 15i is approximately 66.67% deeper than that of the MartinLogan Motion 4i.
- The spatial volume of the MartinLogan Motion 15i is approximately 83.11% greater than that of the MartinLogan Motion 4i.
Please Note: the above comparisons are based on the dimensions of a bounding rectangle that would fit the front face of a speaker. In the case of volume, the comparisons are based on a bounding box that would enclose the speaker entirely. 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.
Our website will allow you to compare the sizes of bookshelf, satellite, tower, and center channel speakers and subwoofers for audiophile and home theater usage. We will keep adding new speakers in response to user feedback. For your convenience, we have also put together a list of links to speaker review sites and more information for each model.
