When I built our theater a few years ago, I found out the hard way that there is a LOT of low frequency information in the front channels (not on the LFE track). I could have routed this to the LFE sub (which is built into the rear seating platform) but I wanted to keep a high-quality sub up front for critical music listening. My "B380 clone" JBL 15" was good in the SQ department, but with only 7mm of xmax, it was farily quick to reach its limits.
Having no practical option for an IB , and no place to put huge boxes, I started down the path of the usual sealed RL-p15 or TC2000. But Mark Seaton and Brian Bunge convinced me to look at the Dayton Reference RSS390 HO. These drivers don't have the Vd of the others mentioned, so it takes more of them. Following the immortal words, "build the biggest box you can live with, and EQ it flat" I settled on four drivers in two 120L boxes - with the drivers mounted on opposing faces. My Lexicon MC-12 prepro handles crossover duty, EQ is a DEQ2496, and power is from a Crown K2.
In one long day on Friday, I sawed up 2-1/2 sheets of 1" MDF, cut a bunch of holes and driver recesses with my Jasper jig, and started assembly. Yesterday, I didn't get much done as I was out on a long training ride for an upcoming 24-hr mountain bike race. Hopefully today I'll complete the assembly and start the finishing process. I had planned on piano black - I have equipment and experience with this - but it is time-consuming... so I may go conventional veneer.
Comments, suggestions?
