Altec Onken Large Horn Speakers

I will offer up my one of a kind hand built Altec Speakers customized to an Onken design cabinet. Speakers were built for me by WPM Speaker Design in San Antonio. Here is some additional info:

Horns: Altec 511B's, 500hz type. New powder coating.

Crossovers: Altec N501-8B, very rare, made only one year and for only one pair of loudspeakers; VOTT A-7 500's.

Woofers: Dayton Audio PA380-8 Pro Bass Horn drivers, spec'd very closely to the original Altec 416-8C, which were used exclusively in the Altec A-7 VOTT's.

Wiring: 12-gauge flat braided OFC.

Cabinet: Onken 360L, designed in Japan but perfected by the French engineer Jean Hiragas. The Onken 360L is a vented design, but is similar to a folded horn in efficiency. The cabinet is renown for its low frequency speed and definition. The cabinet was constructed using 1-inch China Birch plywood, and has been screwed, glued, internally braced, and finished in walnut veneer with 5-coats of hand rubbed satin polyurethane.


These are gorgeous speakers and in mint condition. Less than a year old in fact. Note in the pictures they are actually sitting on floor dollies so I can move them better as these are extremely solid and heavy. They have large feet and will couple to the floor nicely. How do they sound? In a word---Stunning!! Very fast (as only big horns are), dynamic and tremendous bass. They actually sound a lot like my modded Khorns in my living room but with better, deeper bass. Due to their size and weight, I will not ship these. They are available for audition and purchase in San Antonio (actually I'm north of San Antonio about 20 miles). You would need to bring a large vehicle and help to move these as they are quite massive and heavy.

I'm also selling a pair of Quicksilver Audio Mini Mite Tube Monoblocks that really work well with the speakers. If you buy both speakers and amps, I will deduct $200.


Price of the speakers are $2750 (and they absolutely shred most $10,000 speakers I've owned and/or listened to). The price of parts and to have these built is far more than my asking price.4k0u76lqu6cf.jpg
