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.

A larger version of the MartinLogan 6i, the 8i retains its smaller sibling’s versatility, but with larger 4” drivers, it claims improved bass response. With a low-end response of 70hz, these are ideal for perfectly matched Left, Right, and Center channels in tandem with a subwoofer.

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.
