The popular and powerful Logitech Z623 speaker hasn't been such a great deal in a long time

The Logitech Z623 features THX certification, powerful output, deep bass, multiple inputs, and convenient onboard controls all for just $170.

Recently we covered the Google 4K Streamer deal for just $77, grab it before the deal expires as it's an excellent streaming device supporting upto 4K. For anyone looking to set up a home theater alongwith that, the Klipsch Referene series center channel speaker is a nice one to have for only $119.

However not everyone may want a big system as you could be looking for something more compact that can still deliver a big punch. That's where Logitech's Z623 2.1 speakers can help and right now is great time to get one as it's on sale for a low price of $171 (new, unboxed) and $130 (new, open box) (purchase link under the specs table down below).

One of the defining features of the Z623 is its THX certification. This indicates that the speakers are tuned to meet specific performance standards intended to reproduce audio as good as possible for a cinema-like experience. According to the specs, a THX certified device should have an average output of 85dB SPL with 20dB of headroom (peaks up to 105dB).

To deliver this level of loudness, the system packs 200 watts RMS power and up to 400 watts peak output. The 6.5 inch subwoofer driver on the unit claims to go down to 35 Hz, though it is likely at -6dB (F6). Still you should get amazing bass at around 40-80 Hz range with this Logitech speaker.

The Z623 supports multiple input options including 3.5 mm and RCA connections, allowing users to connect various devices such as computers, TVs, and gaming consoles. Control functionality is integrated directly into the right satellite speaker. Users can adjust volume and bass levels independently, as well as power the system on or off without accessing external controls.
