Couplers for Microspeakers: When testing microspeakers, the most effective way to get the best out of your noise reduction software is to shield your DUT from as much external sound and vibration as possible. BaKo's BP1090 Couplers do exactly that. They're compact: the BP1090 Coupler has an external diameter of only about 10cm at the top so it'll fit almost anywhere. They're convenient: with a custom jig, you can quickly load, test and unload speakers, receivers or earbuds. They tell you what you need to know: the internal mic gathers data that can be compared with results from an anechoic chamber or other couplers. Of course, you can use them with other BaKo machines to test FRF, THD and rub & buzz.

which more closely mimics that of an anechoic chamber and for some DUT's it gives better results in THD and rub & buzz testing.

Larger Volume Couplers: Ask us about the BP1090A. This coupler is bigger than the BP1090 and designed to be more like an anechoic chamber. While still easy to load and unload, the BP1090A has an FRF curve which more closely mimics that of an anechoic chamber and for some DUT's it gives better results in THD and rub & buzz testing.

Other Couplers: If our couplers don't meet your needs, we'll design one that does. The BP1090B, on the left, was designed as a low volume coupler where THD and rub & buzz were not important. The BP1090C (not shown) is our largest coupler, which we designed to test speakers for the new generation of flat TV's.
