I have 2 TS-W3001D4's and im putting them in a ported box. I cant find any info on them in order to winISD them and pioneer says put them in 1.6 cu.ft. max which seems too small. I want them to be tuned to 35Hz which i cant calculate because I again cant winISD. If anyone has these subs please tell me about your enclosure im desperate. PLEASEEE
