Bluetooth soundbar with subwoofer from Klipsch, $239.99 down from $499 until the end of the day.
Last year, I got this bluetooth-enabled soundbar and subwoofer combo from Vizio for Christmas, and my movie-watching, gaming and party hosting has never been the same. Where proper home theater systems can cost well into the thousands of dollars and are inappropriate for most non-house living arrangements (try playing an action movie with the bass up in an apartment block and see where that gets you with the property manager), a decent soundbar and sub combo can bring bland TV speakers to life in an apartment or bedroom without breaking the bank.

Until the end of the day, this R-10B soundbar and 8″ subwoofer combo from Klipsch is over 50% off. And if you're intimidated by electronics setup, you can have a professional install it for you.
