About this app

The official app to control, customize, and personalize Sactionals StealthTech Sound + Charge.

StealthTech Sound + Charge is comprised of premium surround sound audio by Harman Kardon and integrated wireless charging, all completely hidden from view inside Lovesac products. The unique proximity and placement of the speakers and subwoofer, combined with the patented technology of sound frequency traveling through the fabric, delivers an unparalleled, immersive audio experience.

*Optimize Based on Configuration Shape*
Patented, enhanced tuning technology adjusts and calibrates the sound properties to the layout of your Sactionals setup, providing immersive surround sound from every seat.

*Tune to Your Specific Sactionals Covers.*
This patented technology adjusts audio frequencies based on the precise characteristics, density, and color of your specific Sactionals Covers for the superior sound quality and immaculate clarity only the Sound + Charge System with sound by Harman Kardon can provide.

*Adjust Sound Properties.*
Use the app interface to control bass, treble, volume, and speaker balance via smartphone or tablet.

*Select, Create, and Save Tuning Presets.*
Choose from Harman Kardon defined tuning presets to pair with Movie, Music, TV, or News. Plus, adjust sound properties on your own to create and save custom presets.

*Enable/Disable Quiet Couch Mode.*
Use this mode to limit the sound and bass coming from your couch, for those moments that don’t call for immersive surround sound.

Sounds good. The app and pairing tech is horrific. I'm constantly having to completely tare apart a large section of my couch to gain physical access to the sub to fully reset the system so the app works. Seriously? Not one engineer thought "gee, we should put the sub in a storage base instead of a standard base so you can access it without having to tare apart half the couch apart to flip over a section for access. I'll be returning it all.

The soundtech inside our couch is great. We love the functionality of the in-couch speakers. Unfortunately, the remote that comes with the speaker system lacks the ability to customize sound settings, leaving you to the preset options which leave something to be desired. The app is the only way to truly dial in your experience. The problem is that the app doesn't stay connected to the system. When it works, it's fine, but it rarely works without a fight, and it always requires reconnection.

Won't connect through app if you've already connected via BT. Meaning that I paired my phone & streamed music before I downloaded (which is good, force app usage would devalue the product). However, the app won't see the equipment if you do. Apps purpose is to control individual speakers &c. So 4 stars as it works, but it took a bit of back and forth before I caught on to delete the blue tooth connection to make the app work.
