TAV Technology—Tuned Periodic Vent technology (TAV) allows a smaller cabinet to provide lower frequency response without using passive radiators and very high power amplifiers. Subwoofers incorporating TAV technology are able to deliver higher amounts of lower bass frequencies from a smaller enclosure for increased performance. TAV Technology is currently used in the MS-10.1 subwoofers.

RDAB Technology—RDAB TechnologyResonance Damping Alloy Baffle (RDAB) technology dampens cabinet vibrations and minimizes tweeter diffraction for increased sound quality and performance. RDAB not only enhances the clarity of the speaker, it tempts you to leave the grilles off! The baffle on our speakers is the front face of the speaker where the drivers are mounted. (Baffle— a device (as a plate, wall, or screen) to deflect, check, or regulate flow or passage (as of a fluid, light, or sound).) RDAB technology is used in our MC Series freestanding speakers.

70 Volt Compatible—A built-in transformer allows the speaker to be used with 70 Volt amplifiers. Typically RBH Sound transformers feature multi-Watt taps to allow for greater flexibility. 70 Volt compatible RBH Sound speakers: HS-615, A-605/70, and R8

Bi-polar/Di-polar—Bi-polar and Di-polar speakers have more than one tweeter, and usually the second tweeter is located on an opposing surface to the first tweeter. Bi-polar speakers are in-phase with each other, while Di-polar speakers are out-of-phase with each other. The advantage of Bi-polar and Di-polar speakers is their ability to emit the same (Bi), or opposite (Di), sound from both surfaces at the same time. The reflections of an omnidirectional sound source like this trick the ear into "hearing" a larger presence and, in certain cases, diffuse the sound to prevent the ear from pinpointing the actual location of the speaker. RBH utilizes this technology for surround speakers in a home theater system. Bi-polar/Di-polar RBH Sound Speakers: 44-SE, 66-SE, and MC-44C.

Dispersion Control—This feature allows the speaker to either focus its sound in a closer area or broaden the sound to encompass a larger area.

Dual Voice Coil/Single Point Stereo—The use of dual tweeters and dual voice coils in the woofer allow speakers with this technology to play both channels of a stereo audio signal from a single speaker. This speaker works great in small areas (i.e., bathrooms, hallways, game rooms, etc. ask your RBH Authorized Dealer for more information. RBH Models: A-615D and R8.

Left, Center, Right (LCR)—This feature allows a speaker to be used for the left, center or right channels in a home theater system. Speakers with this capability have another special feature, such as a 15-degree offset or additional drivers, which give the speaker home theater capabilities beyond that of a regular speaker. LCR RBH Sound Speakers: T-1, and T-1/R, SI-760, and SI-760/R, SI-770, and SI-770/R, SI-663, and SI-663/R, 441-SE, 661-SE, and 661-SE/R, WM-30, MC-414C, MC-616C, and C-4.

Swivel Tweeter—Swivel tweeters allow the directional high frequencies to be aimed at the listening position for better frequency response.

Treble Contour Switch—This switch allows the tweeter’s output level to be increased or decreased by 3 decibels to provide better sound quality and to better match the listener’s tastes.

Woofer Contour Switch—This switch allows the woofer’s output level to be increased or decreased by 3 decibels to provide better sound quality and to better match the listener’s tastes.
