I have read many reviews and personal experiences with these subs, so I am hoping someones personal experience with them can help me. I have bought a 10D4 for SQ purposes, and I am torn between box types. I have the recommended space for the recommended sizes .9 sealed and 1.25 for ported, I could even go as far as saying I have enough room for a transmission line box. I have plenty of power for it, and a very good processor, I really wanted to know if someones heard them in different boxes and which ones have impressed them most. The speaker is already on its way, I just don't know what type of box to build for this particular Sub.
