Heathkit As-1348 Huge Speakers??

mr.veg · 9th June 2005, 04:34 PM

I saw these at a pawn shop..could not find any info about them on the net. The configurations is: 15" rear firing woofer, two 5" mids on front at top, and THREE DOME Tweets in a semi circle array. MODEL NUMBER IS AS-1348. these puppies are huge, but I have no idea wether they will be worht the pruchase price of $199..even if I test them in the shop it won't be the same with good equipment andn the pawnshop has is a huge cavern, so there will be no real performance test to be doen before purchase. If anyone has a clue as to the quality-performance-origianl price tag-specs, I would be very apreciative!

The 1348 was designed by John Bruss who later, I believe, was chief engineer at Koss. John did some good work but I don't remember much about that particular design. A friend of mine had a pair and I do remember some exceptionally low bass output from that 15" woofer.

As I recall, the 15 was in a sealed enclosure with the front of the cone driving a slot in the rear of the cabinet...a fairly unusual design. I think system resonance was down around 10Hz with that arrangement. I do not remember which drivers were used or anything about the crossover network.

Fairly nifty cabinets if they are still in good shape. The 1348s were relatively expensive when new and only a few hundred were sold, so probably a rare find for a collector.

THNX PAUL. How did you know about the MODEL..it seems so rare and odd for HEATHKIT ans such a an odd design. YOu are right the bass driver fires out the back through a slot.. I am going to buy them and I will posts a follow up as to the response and general sound.
