The KH 310 A features a Mathematically Modeled Dispersion Waveguide (MMD), flexible acoustical controls, various input options and an extensive range of mounting hardware. This allows the loudspeaker to be used in diverse acoustical conditions, with any source equipment and in a wide variety of physical locations. The KH 310 represents the latest in acoustic and electronic simulation and measurement technologies to ensure the most accurate sound reproduction possible.

It can be used in project, music, broadcast centers, OB vans, and post production studios for tracking, mixing, and mastering.

Sound Anchor ADJ2 Stands are designed to make proper speaker placement possible. When monitors are positioned properly on rigid stable platforms they work better and the sound is enhanced. The entire sound field has more clarity, tones are more accurate, dynamic contrasts are greater and subtle anomalies in the mix are more apparent. The ADJ2 is ideally suited to the new breed of midsized super monitors that have recently become popular in studios.

The base of the ADJ2 stand is 17" X 23". This stand works best for speakers that have a width no wider than 24 inches and a depth no greater than 18 inches. Smaller speakers will also work on the ADJ2s. The common solutions for speaker support (shelves, flimsy wall mounts and meter bridges) are not good solutions. They do not isolate your monitors from your electronics, your monitors from each other or your monitors from the structure. Along with these three drawbacks they seldom position your monitors exactly where they need to be for best sound. Sound Anchor stands address and eliminate these three drawbacks.

The Sound Anchors ADJ2 stands allow the engineer to correctly place a pair of monitors behind his console. These stands allow height and tilt adjustment of the monitors. The 17" x 23" base and the upright are filled and damped from the factory. ADJ2 stands offer a very solid, stable and non-resonant support for your speakers. The speaker platform is made of 1/4" aluminum which reduces the amount of energy that gets transferred into the stand. The Sound Anchor ADJ2 stands isolate the speakers from the console, each other and the floor which gives you a cleaner, more detailed and more accurate sound.

Sound Anchor ADJ2 stands are ideal for:

1. Music control rooms.
2. Surround sound monitoring.
3. CD mastering.
4. Radio and television broadcasting studios.
5. Film post production.
6. Video game production.
7. Online audio production.
