I've been working with WinISD to put together a ported box for a pair of the new "er" Type-R's but I really am in over my head. I'm pretty new to WinISD and can just do some of the basics but don't understand yet how to get my desired result.
Anyone out there been somewhat im my situation before and either has some figures for a ported Type-R box or could put something together in WinISD for me?
Already had them in a sealed box with about 800 watts RMS and sounded pretty good, as far as Type-R's can but in reality I'm really not a fan at all, but am looking for a little more output.
Any feedback welcome.
