I posted this over on AK and thought I'd post it here. I may be doing a speaker project this winter. Wish I had a CNC router (Anybody have access to one?). I may also be re-Veneering my Epicure 20 + speakers (mahogany of course).
I was shopping for a set of D405's for a project and after seeing prices all over the place ($139-$250 each), I tried to figure out why the price spread. I see that the ratings for power are 100-150 watts/300 watts peak, and then I see the D405 Trio, the D405si, and the D405 Selenium so I decided to go to the JBL website and after 3-4 emails to the tech section, I quit trying. I got no response from JBL. Anybody know how many models of the 405 there really is? JBL's website shows only one version. The specs are all over the place so I'd just like to know if the $139 unit is not the same as the other versions IF there ARE different versions. Maybe it depends on the diaphrams (Maybe phenolic/kapton/titanium???) I used a pair on my Cornscala A's several years ago but they are long gone sold and don't remember if there was different versions back then. JBL's support sucks the flabby bag. I also DID notice that the drivers looked different where the wires attach. Some were down at the 6 O'clock position and another was at the 3 and 9 position.
The 1" Diameter is a typo from a vendor. It IS a 2"
