You can download the owners manual if you don't already have it. http://iweb.alpine-usa.com/html/asb/...r-1221d_om.pdf It will give you the Theile-Small parameters. You can then plug these into a program like Blaubox and it'll give you dimensions for ports and frequency response graphs for the enclosure. The good thing about this is that you can play with volume and port sizes to get the output you want. http://diyaudiocorner.tripod.com/software.htm Good luck. -- thelizman "I didn't steal the FAQ either" Before you ask a question, check the FAQs for this newsgroup at http://www.mobileaudio.com/rac-faq.
