My next open baffle project will be this Akai/Foster 12" woofer matched up with a JMI Japanese Machinery and Metals 4" full range speaker.
The JMI full range resembles a Foster FE-103 speaker in every fashion. The JMI and Akai are both ferrite magnet speakers. Presently I have them set up on a temporary baffle until I make some new baffles. I am running both speakers without a crossover, relying on their natural roll off, so far this combination is the one I like the best out of the three I tried today.
Of course the finished product will not look like this, this was just a temporary set up to get an idea of matching the speakers and the sound.
I tried these 4" alnico full range also and found I needed to croos them over with a 15uf capacitor, still the 4" speakers shouted louder than the woofer and the bass was mismatched to the woofer output.
Last I tried a pair of Foster FE-163 speakers, these too were much more efficient than the 12" woofers and sounded unbalanced. I think the Foster Fe-163 will saved for a back horn loaded speaker build in the future.
