SANSUI J33 2-Way Performance Bookshelf Stereo Speakers

Sansui high-performance two-way air-suspension compact speaker system featuring seamed-sheet cone woofer, soft-dome tweeter and luxurious black-luster finish. 60W power handling, 90db/W efficiency and 45—20,000Hz frequency range. Two-way design & mirror-paired units for incomparable stereo imaging. Crossover frequency: 2kHz.
The speaker system of the piano finish which took in the design which returned to the origin of the bookshelf and attained high-quality sound-ization in the compact size.
The 21cm cone type Woofer which used the sheet seamed cone is carried in low-pass.

This sheet seamed cone is giving the intensity with the form of the carved cone with the quality of the material which was rich in the uniformity with little unevenness of density or thickness. Moreover, the magnetic circuit using a large-sized ferrite magnet attained the flux density of 9,500gauss, and combination with the voice coil of 30 phi etc. has realized the high efficiency and the high input-proof.

The 2.54cm soft dome shape tweeter is carried in the high region.

While using for the diaphragm what applied the acrylics system dumping agent to polyester fiber by the special way and obtaining the outstanding directivity peculiar to a dome shape, the harmful vibration is absorbed moderately.
Increased specific gravity and high-density particle board are adopted as an enclosure, and it has a sealing structure which made this the edges stop structure. Moreover, the modification of the orientation is aimed at because make it a tweeter come to the outside of a baffle and also it considers a unit placement as a symmetrical design.
Piano specular surface coating finish is adopted as sheath finish. It started in the foundation coordination (polish) and two under coats, grinding, three coatings, grinding, and wax buff finish have realized beautiful finish.
