Hey I'm looking to build my own box for my two type r 10's because I got them in a bandpass box with the plexi infront, and it doesn't hit the range I want. so far I haven't seen what I wanted. I was wondering if anyone had or could give me plans for a ported box for both that is around 32 or 33 hz. I'm running them in a 1990 suburban with two 500w monoblock alpine amps so there is a ton of room inside and I don't know what would be best to get the most volume from them. Also having drawn out plans would be nice for building too. Thanks a ton for any help or suggestions.
