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.

The TSi200 from Polk is the flagship model in their TSi bookshelf series. Using quality components with a premium finish, Polk is aiming for a high-end audiophile experience at an affordable price. Clear, natural-sounding mids and highs - the rear port design makes them sensitive to positioning as it relates to bass output, so experiment with placement.
