Hello to all,
I recently , for some crazy reason decided,to have built a pair of speaker cabinets. They were completed in late Jan. They comprise JBL 123-A Twelve inch bass drivers powered by (for now) a Niles 1230 solid state power amp @30w per channel. The mids , and upper frequencies are handled by a pair of Klipsch 400 squawkers,and the Bob Crites upgraded high freq horn, as used in the Klipsch La Scala. They REALLY do look fantastic.
The Klipsch 400 sits on top of the bass cabinet, isolated, by a sandwich of sorbathane and walnut, at the front and a custom made bracket of machined aluminum, that allows the horn to be moved forward or backwards, and vertically by about 3.5 inches. Ok, here's the problem( two actually) No1: not enough Bass. The cabinet has a 1.75 inch thick front baffle. The rest is 1" MDF, and about 5 cu ft. with lots of acoustic material.(ultra touch acoustic batting, and acoustic foam). No2: No pinpoint imaging. The soundstage is kinda diffuse, is this typical of horns? P.s. The Klipsch horns are powered by a pair of Audio Research tube monoblocks (M-60, circa 1969)THANKS IN ADVANCE FOR ANY HELPFUL SUGGESTIONS.
