In-wall speakers are ideally placed for serious listening. Listening from in front of the speakers is considered to be the most natural way of enjoying your music or movie soundtrack — it is also great for your well-being!
If you have space for dedicated listening, consider in-wall speakers. When placed at ear-level, they provide a more direct field of sound and a "sweet spot" for stereo imaging. This makes you feel more like the band or recording studio is right in front of you.
