Please some advice on my onken cabinet build with altec 416b woofers. Hello Lads, I had posted before on Altec 515B cabinets, but since then I have changed directions, as I came into a pristine pair of Altec 416B woofers, and have decided on building a pair of full size Onken cabinets for them with my 288C drivers with the German Jabo conical horns sitting on top.I am contracting with a cabinet maker to acquire the wood and do the cuts, as I do not have a table sayw that can do the precision cuts needed for a tight build, and his big shop saws can do.
He will also cut out the speaker hole and drill all the screw holes for me. I will end up with a "kit" that I can assemble in my garage.I need to make final decisions on the build before wood hits saw. He can get 13 ply Baltic Birch plywood in a high quality form. I can order 3/4" or one inch thick sheets, The problem is that one inch sheets adds $40.00 per sheet over the 3/4" That's $240.00 extra to the total cost of the six sheets needed for a pair of cabinets.So the question is, IS 3/4" adequate?

A very flat response in the band 800Hz - 20KHz. Untitled Document. DECWARE Imperial Folded Horn. The Redesigned 1956 Jensen Imperial Reproducer by Steve Deckert The original Jensen Imperial started back in the days before Stereo when people listened only in mono. Speakers were sold as raw components and consumers built their own enclosures or had them built.
Manufactures like Jensen offered plans for various speaker cabinets that would accommodate their new fixed magnet moving coil speakers. You might think "...mono, gee what's the point? " but trust me, one of these speakers would fill a room with live sounding music very well. Jensen Imperial plans - Speakerplans.com Forums - Page 1. I have just built 6 half imperials, whilst they play low they produce a fairly even and balanced sound between 30 and 500 hz. The phase dip is much much less pronounced than on modern scoop designs, i'd argue it acts more like an average size reflex box with a huge flared port than a modern small chamber long horn type design. I've wanted to build some of these for years which is strange considering my general dislike of scoops and the typical scoop sound. My view is that modern scoops have been fixed and fixed and fixed by a number of people since the early days of king tubby using them. sometimes you have to build something to find out if the original was broken in the first place.

Klipsch. Tannoy. CAF 2014: Blowing my Sousahorn like I just don’t care. One of the most visually striking demos I caught at CAF this year was from show-organizer Gary Gill and his Sousahorn display. The Sousahorn is derived from the Le Ceac’h exponential horn designs, currently sold under the brand names of Azura or Oris — essentially, it’s a honkin’ big horn, a component in a DIY loudspeaker design. Gary, who manufactures and sells the Sousahorn locally, says there are two sizes available, both with a 7″ “throat opening”, large enough to suit a Lowther, Tang Band and many more full-range drivers.
Price for the 34″ diameter horn is $750; the 40″ diameter is $950. Shown here with some bass cabinets that Gary made to show off the horns, the resulting speaker shown was a large, high-sensitivity three-way with a Lowther shoved deep into the horn, with tweeters dangling off the audio rack. The whole thing was tri-amped using electronics from Emia and LM Audio and wired up with cables from Triode Wire Labs. DIY Open Baffle With Widerange Drivers A.K.A.
