Since I had a pair of JBL 2205A's woofers</div> <div> hanging around, I decided to build pair of Subs with them. The result is The Sisters. These</div> <div> are 2.5 cubic foot cabinets built of 1 1/2" MDF and twin ported. One is turned to 60 Hz</div> <div> and the other to 50 Hz.</div> <bR> <div> The reason this are tuned so high is because they already have a Step-Sister.</div> <div> This one which is yet to be refinished to match is a 4.75 cu. ft. cabinet housing</div> <div> a twin ported JBL 2234 turned to 40 Hz. </div> <bR> <div> All three subs are equalized using a custom homebuilt 4 channel equalizer using the </div> <div> Machand Electric's "Bassis" boards. The Sisters use 1 channle each while two channels</div> <div> are daisey chained for the Step Sister </div> </td> </tr></table></body>
