[QUOTE="bumpin buick, post: 5789653, member: 578001"] [SIZE=14px][B]15” Heads-up Challenge[/B][/SIZE] Proposal – Collect 15” Dual 2ohm models from several companies to do a variety of tests to compare the subwoofers. Testing Setup 2000 Toyota 4runner 250amp EA alt DD Z2lv or RD D9s 6 Stinger SPV70s Boxes – Nine different boxes will be built (all 1.5” mdf) •3 Bassrace Boxes •3 Spl Boxes •3 Daily Boxes Tests- • 30 second bassrace average (all subs will be on the same song which is not appointed yet) • Spl burp peak score • Daily will be tested by ear, this is obviously an opinionated decision but we will try and do the best we can in this case. Scores- Bassrace and SPL peak will be held on a Termlab mic, which I have two in my possession. Boxes will be built by Mike Strass, a well respected box builder in the greater Chicago area. AS of right now RD has confirmed testing several of their 15"s waiting on several other companies including DC, Cascade Designs, Sundown, and Others. If you are a subwoofer company and would like to be involved please PM me. [/QUOTE]
