About GB UltraTheater Who we are : GB Audio is a web based speaker manufacturer dedicated to producing the highest quality products for the Home Theatre sound system. We assemble speaker units using Drivers from different American and European manufacturers. We use Audax, Dynaudio and Morel drivers among various other top brands. We couple these high technology drivers with our own dynamically balanced crossover systems, the DBX enhancement technology, extremely efficient and well planned box designs and other advance speaker circuitry. The product of these two blends is topnotch theatre grade sound. Our commitment : We are commited to providing our customers with speakers that surpass the top brand names, such as Polk and JBL for an affordable price. Unlike these brand name speakers, we do not manufacture the drivers themselves, instead, we buy drivers from well known, proven vendors. We tune our precise enclosure calculations to allow each driver to operate at its maximum efficiency while providing good sound dispersion for the Home Theater. What distinguishes us from any other speaker manufacturer is our ability to create electronic technologies that enhance each speaker unit. These technologies are all incorporated into the DBX sound enhancement system. Sales Policy : Though traditionally speakers are always tested out before they are bought, we believe that our speakers are good enough to be backed by our 20 day money back guarantee. See Sales.
