High Efficiency Speaker Asylum

Beyma - high efficiency Spanish 12" speakers

124.180.241.251

Here are my finished speakers based on the Spanish Beyma drivers (12XA30/Nd). Box is only 30ltrs and ported due to very low Q of drivers. There is bracing and dampening inside and very simple external Xover at 2Khz. Over all efficiency now is 98db. Built these to work with my low power tube and SS amps. Drivers are rated to 350W! There is not much low bass and therefore I use them with my powered stereo sub-woofers (pictured).

Nice look. Who made those great looking grill covers?

  The grill covers are an off the shelf item at Jaycar in Australia. Cheap and effective. Held on by magnets. They just pop off. They must be off when speakers in use.
