Select two speakers:
MartinLogan Motion 15i vs. KEF Q150
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.
KEF Q150 Bookshelf Speakers
Known for excellent detailed midrange and highs, with an open soundstage. Bass is also good, but can be somewhat placement-dependent, so experiment with positioning. Unique Uni-Q driver places the tweeter inline with the midrange and bass cone for better imaging from multiple positions.
- The front face of the KEF Q150 is approximately 8.87% larger than that of the MartinLogan Motion 15i.
- The depth of the KEF Q150 is approximately 15.20% deeper than that of the MartinLogan Motion 15i.
- The spatial volume of the KEF Q150 Bookshelf Speakers is approximately 25.41% 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, or in the case of volume, the comparisons are based on a box 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.
