"I wish I could tell you why what happened happened, but I can't. All I can tell you is that when these battery-powered cubes filled with a secret blend of crystals appeared in my listening room, everything changed for the better." — Jonathan Valin, The Absolute Sound

The SteinMusic Harmonizers have been our favorite tweak for more than ten years. Not a strong candidate, not a conditional recommendation — our favorite, period. The H2 PLUS Signature is the current flagship expression of the technology.

The PLUS and Signature Upgrades

The H2 PLUS adds a Blue Diamond element to the standard H2 configuration. The Signature level represents the highest refinement of the Harmonizer technology — more crystals, more carefully selected, producing a greater effect on the acoustic field properties of the listening room. Best used in pairs, placed near the speakers. The combination of two units creates a field effect that neither unit achieves alone.

Press Recognition

Jonathan Valin at The Absolute Sound reviewed the Harmonizer system with the quote above — a review that generated more reader inquiries than almost any other accessory review in the magazine's history. Positive Feedback has also covered the Harmonizers consistently.

Specifications

  • Type: Battery-powered room harmonizer
  • Level: H2 PLUS Signature

Room divider
Color: Black, Color: Black
It was much simpler than anticipated. I don't think it's very sturdy and it lacks weight, but it's attractive.

Really adorable & functional room divider! I love mine!
Color: Dark Coffee, Size: 4 Panel
Really beautiful divider. I use it out on my patio at my apartment building to provide privacy, shade & keep my things safe. At 6 foot tall and 4 panels (I strongly suggest 4 panels) it's quite a lovely addition to my home. It's delicate so handle carefully but it comes completely put together & just set it up. Being able to move it inside or outside or wherever because it's so light makes it very mobile. It's not too opaque you can see through it but if it's for total privacy use a tablecloth or something behind it to make it less see through. It's strong and big and I had a question for their cs and they responded immediately and handled it right away which is a sign of a good company. It's light so make sure you secure it if it's windy for stability.

Nice Look
Color: Dark Coffee, Size: 8 Panel
Attractive and Very versatile. Pretty sturdy, but use care if you buy larger screens when moving. Hinges are small so moving it recklessly could break them. Overall I would recommend this screen. I love it
