Review: Well packaged - Well packaged, looks and sounds great. Not too loud though, might be how I have it configured
Review: Nice Clean Sound - * I added these as height speakers to my 3.1 home theater setup. Upgrading to a 3.1.2 configuration unlocked a bunch of new audio modes on my AV receiver. * I really like the clean and detailed sound. These speakers add an extra layer of ambiance to my movies and give my music a fuller sound. * They look really nice and well-made. With the front grill on, they even resemble an Xbox Series X. * Overall, I'm happy with these speakers and glad I added them to my setup.

## Features

- ALL NEW 90° x 90° TRACTRIX HORN: Experience the cleanest, most natural sound possible. The increased outer horn dimensions allow for directivity control over a larger bandwidth of frequencies, resulting in improved high frequency directivity and a more accurate sound stage.
- LINEAR TRAVEL SUSPENSION (LTS) ALUMINUM TWEETER WITH KAPTON SUSPENSION: The 1” LTS tweeter minimizes distortion for enhanced, detailed performances. Aluminum is an extremely light and rigid material used in the tweeter assembly to provide high efficiency and improve resolution and detail.
