And cancel that.
So I hooked up a newly acquired pair of JBLs last night, and could not believe how boxy and artificial the mids were. Nothing like the realistic and open mids on the Wharfedales.
So, instead of running one long wire through both sets of posts on the Wharfies, I put a jumper on the speaker, and hook up one section. I also disassembled the speakers, and matched the woofers - one tower now has 2 x 1751 and one tower has two 1751H drivers in it.
Well, hello bass. Not as much as the 8" in the JBLs, but finally some proper extension, and proper low notes coming from the front ports.
So I have no idea where the lack of bass was - I tried bi-amping (through reassigning my rear surround channels to the front), and a normal hook up with the bare wire through both sets of binding posts, and neither was producing bass. However, swapping the drivers, and using a jumper plate suddenly produces bass. What gives?
Regardless, the JBLs are now being reassigned to stereo duty on my vintage system in the basement.Edited by ScooterMcTavish - 3/13/14 at 5:57am
