Select two speakers:
MartinLogan Motion 15i vs. MartinLogan Motion 30i
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 30i Center Channel Speaker
Similar to the MartinLogan 50XTi, but slightly smaller, with 5.25” woofers, this center channel still has large-speaker presence, with a respectable low end response of 65Hz. Inclusion of the Folded Motion AMT-style tweeter gives this speaker clarity and can handle louder volume levels with little evidence of compression.
- The front face of the MartinLogan Motion 30i is approximately 46.87% larger than that of the MartinLogan Motion 15i.
- The depth of the MartinLogan Motion 30i is approximately 10.53% deeper than that of the MartinLogan Motion 15i.
- The spatial volume of the MartinLogan Motion 30i Center Channel Speaker is approximately 62.32% greater than that of the MartinLogan Motion 15i Bookshelf Speaker.
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 cube 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.
