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.

Before the MB42X, there was a popular crossover mod for the older MB42 speakers, making them sound amazing for the price. These are essentially MB42s with the improved crossover built-in (which is a good thing). Other upgrades are cosmetic, including a tweaked cabinet shape, graphite finish, and magnetic grills.

Notice: 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 measurements 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.
