Bought a pair of very large and heavy TEAC LS-400 speakers made in Japan in the 70s and they were all good except one woofer was blown. All components have been tested for sound as well as ohms. The woofer and the midranges have treated cloth surrounds that are in good shape. Both the woofers and the midranges have heavy magnets. Midranges come with boxes for mounting. The components are in separate auctions listed below with the component for sale in this auction highlighted: Pair 3-Way Crossovers4 - 2 16 ohm horn tweeters (Pairs attached in series for 8 ohm)2 - 4 1/4 8 ohm Midranges #12 - 4 1/4 8 ohm Midranges #21 - 12 Woofer 8 ohm.

Annihilator HA-800c by Hohmann | 400 Watts X 2 CH | Bridgeable W/Crossover. Old School at its best! Fully tested and working flawlessly! Free shipping!

Ross Mega 400 Power Amp 1990s Grey. Condition is Used. Shipped with USPS Ground Advantage.

Crites CS 400/4500Hz Crossovers in Beautiful Cedar Wood. As model indicates, frequency on these is currently crossed at 400Hz to the mids, then at 4500Hz to the tweeters. These were built with high quality Sonicap capacitors. Cedar Wood mounting option was more expensive when I purchased these; it is stunning, and it is no longer readily available that I can see from Crites at his website. Lightly used in my Cornscalas. Perfect condition. See photos. Separately selling my Atlas Sound PD-5VH mid compression horns, Klipsch K400 horns, Crites Cast Frame 15 Woofers, and CT-125 Crites tweeters and ALL in perfect shape. This listing is for the Crites 400/4500Hz Crossover only (1 Pair). Will only ship to the US, 48 contiguous states - no Alaska, no Hawaii, no Puerto Rico. No International shipping.

Below you will find some info from the net. Also in some of the last pictures you will find a complete set of these for reference purposes only. I tested the speakers then removed the components and put the cabinets on the street. The list below are the components that are in separate auctions with the component in this auction highlighted:2 - 3-way Crossovers4 - Tweeters2 - 5 Midranges2 - 12 Woofers - Need surrounds2 - Grille Covers Frequency Response: 38 to 20,000 Hz ± 3 dB, down 10 dB at 28 Hz, free field. Dispersion: 180° at 10 kHz. Impedance: 8 ohms. Drivers: 12-in. woofer, 5-in. midrange, 3/4-in. tweeter, two angled 2-in. super tweeters. Crossover Frequencies: 700 Hz, 3 kHz, and 7.5 kHz. Enclosure: Oiled walnut finish, fully sealed.Dimensions: 27 in. H x 15 in. W x 13 1/4, in. D.Shipping Weight: 53 lbs.Price: $279.95.Technics by Panasonic is not new in high-quality consumer audio. One of the better loudspeaker systems made under this trademark is the Model T-400, a four-way, five driver system intended for floor mounting. The enclosure measures 68.6 cm. H x 38.1 cm. W x 33.7 cm. D. (27 in x 15 in. x 13 1/4 in) and weighs 24 kg. (53 lbs.).The sides and top are finished in oiled walnut, and a colorful sculptured foam and cloth grille accents the darker wood tones. Since the T-400 is generally intended for mounting adjacent to a wall, the rear of the cabinet is stained but not furniture finished.Speaker connection is made to two well-marked terminals in a recessed cavity on the rear of the enclosure. Tweeter and midrange-level switches are placed directly above the terminals. Each of these is a two-position switch, with the up position corresponding to normal equalization and the down position corresponding to a 3-dB level reduction.A 30.5-cm (12-in.), high-compliance woofer is mounted on the bottom of the front panel and works into a sealed enclosure. A 13-cm (5-in.) midrange driver and 9-cm. (31-in.) tweeter share the central portion of the front panel, while two 5-cm. (2-in.) super tweeters are mounted at the top, angled away from the front axis for broader dispersion of the highest frequencies A very clearly-written instruction manual accompanies each speaker.
