Multiple small-diameter driver configuration.

In combination with narrow baffle geometry- this configuration provides a slender cabinet that sounds awesome. Why use smaller drivers instead of one huge woofer? Many reasons, first smaller drivers are capable of better detail than their larger counter parts. They also project sound over a wider area, so every seat in the house gets great sound. Second, we can minimize the width of the cabinet making it sleeker, giving you more room for a larger screen.

Silk dome tweeter and polycarbonate drivers.

The nuts and bolts behind TSi's clear and crisp sound quality. Forget speakers with harsh horns or hard metal dome tweeters- they'll grab your attention at first but after prolonged listening, your ears will get tired. TSi's soft silk dome tweeters and polycarbonate drivers sound smooth and natural. Your ears will relax and thank you.
