Atlantic Technology & Solus/Clements Pump Up the Bass with H-PAS
By Rachel Cericola
Big bass does not have to take up your entire living room floor.
Atlantic Technology and
Solus/Clements have teamed up for H-PAS, a new bass technology that will allow deep, low-distortion bass from cabinets that are 50 percent smaller. That also means you can expect some smaller drivers.
Designed by Philip Clements of Solus/Clements Loudspeakers, the patent-pending system combines several speaker technologies, including bass reflex, inverse horn, and transmission line. No special drivers are needed; it's a purely passive system that's compatible with any and all amps and receivers.
"This new system is the first ever to break the famous Iron Law of loudspeaker design, which states: 'deep bass extension, compact enclosure, or good efficiency... pick any two at the expense of the third'," says Peter Tribeman, the president of Atlantic Technology. "For the very first time, due to Phil Clements' breakthrough design, we can have them all."
The units don't sacrifice quality, but should be easier to produce. Hopefully, some of that cost savings will trickle down to the consumer. Even better, the two companies plan to share the love and license H-PAS to other manufacturers.
If you're in the area, expect Atlantic to have a few prototypes at the CEDIA Expo in Atlanta, Georgia, from September 10 through 13. That unit will include two 4.5-inch drives in an enclosure that measures 1.4 cubic feet. The company says it can produce bass that extends to 29 Hz (-3dB) at Sound Pressure Levels that exceed 105dB, with distortion under 3 percent. That type of performance would typically be found in a unit with bass drivers that are triple that size, with twice the enclosure volume.
Atlantic Technology plans to release its first H-PAS product, the H-PAS-1 floorstanding speaker, in the fouth quarter of 2009. Solus/Clements will add a 6.5-inch H-PAS tower and bookshelf models early next year.
