Thanks for reminding me about that file. I've seen you mention it a few times but I didn't realize it had the specs for the 2035. My copy is an old printed version from the 1980's and it doesn't list it.According to published T/S specs, the JBL 2035 will work best in 1.5ft3 to 3.0ft3 cabinets tuned to 54Hz. PiAlign suggests 1.7ft3. Response is nice and flat but not too extended, the 3.0ft3 box has f3 of 50Hz and the 1.5ft3 box has f3 of 80Hz. This one is probably best used as a midwoofer and augmented with a sub.
