Having trouble getting through movie night without nodding off and spilling the popcorn on the couch? Maybe it's time to upgrade your sound with Polk's Blackstone TL150 speaker system. Ideal for small- to medium-sized rooms, this convenient package gives you dramatic, engaging movie theatre sound that'll keep your attention focused and your eyes glued to the screen. The four Blackstone satellite speakers and the centre channel use some pretty advanced driver technology, so you experience impressively effortless sound from speakers that take up very little space. Just add a Polk subwoofer to get deep, rumbling explosions and room-thumping bass for all your favourite action flicks. You can even upgrade to a seven-channel home theatre when you add a pair of TL1 satellite speakers to this system.

Advanced technology produces astonishingly realistic sound
Polk's latest breakthrough is "Time Lens" technology, which aligns the drivers in such a way that all the frequencies reach your ears at the same time. It improves the speakers' soundstaging and imaging, so that you'll start to forget you're watching a movie and really feel like you're part of the action. This technology makes this system great for video games, too, because you'll be able to clearly pinpoint where sounds are coming from all around you, like monster roars or enemy gunfire.

Polk's enclosure design puts performance first
The satellite and centre channel speakers also use an "acoustic lens" in their grilles to disperse sound waves in a way that makes your movie and music soundtracks sound larger and more open. And unlike a traditional port hole, these speakers have something called an "aperiodic-tuned rear port." It's more like a breathable membrane that controls air flow in and out of the enclosure, giving them the acoustic benefits of both a sealed and a ported enclosure, including better bass extension and a pleasing mid-bass boost. It also means you can place these speakers in the open or against a wall, and still get great sound.
