I have one alpine type r 12 and want to build a ported box. But I need the materials to do it and the specs. Somebody with experience please give me the list of materials i'll need and the specs for a ported box. I prefer it to be tuned to 36Hz.
I've had previous Alpine Type R 12" speakers, and purchasing their most recent version from Sonic Electronix was good move! Great product for way less than you'll pay anywhere else. I'm consistently impressed with Sonic Electronix 's product selection and shockingly low prices. I will continue to support and recommended this Company.
