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.

Like their larger siblings, the Motion 4i’s, the MartinLogan 2i speakers feature the company’s legendary electrostatic tweeter technology, and is often used in surround systems. They can be used as small bookshelf speakers and excel at surround channels as well.

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, measurements 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.
