The Bottom Line We liked BMS so much that we became the largest direct purchaser and end user of BMS products in the USA. Sadly, too many products in the audio industry are sold by hype and name recognition. BMS is a product that actually delivers as it is described. BMS is used in many speaker boxes as OEM products. Our mission is to also bring what we feel are the best drivers in the world to the small, independent user. Hearing is Believing. Specifications & Pricing

We don't just sell them, we use them.
| Assistance Audio first learned about BMS at NAMM in 2000. We liked what we heard and bought some. Initially, we began simply replacing JBL 2450s in some of our front of house speakers. The difference was astounding. The speakers with BMS were much more efficient, clearer, and cleaner. The BMS are so efficient we were not using the HF amps very much at all. To make better use of our power, we lowered the crossover point, which was very foreign to us as a lifetime 10” midrange company. We were used to using cones to cover as much spectrum as possible, both for speaker protection and sound quality. BMS reversed our thinking. The BMS were much clearer in the 700-1200 range than the 10”, and were missing the “gack” or overring that the JBL compression drivers have. The BMS breathed new life in our whole system. Soon we went about replacing all the old drivers and selling them on eBay. We began utilizing DDS horns to fully realize the BMS potential. Our new systems are designed around the BMS and DDS. To improve our buying power, we became the largest non-OEM user of BMS in North America in 2001. |
