Internally and externally maintained! This is the second generation of Tannoy's famous machine ARDEN. The warm and soft tone is attractive. It plays all kinds of music lusciously and gently. In particular, it works great with vacuum tube amplifiers, and the sense of orchestra scale and smooth playback of stringed instruments are satisfying enough to listen to. The exterior has been beautifully finished due to exterior maintenance. Serial 011093 016017 (Tomonori Asaine)
Maintenance information: 2024.4.18 Maintained (exterior repair/polishing/oil finish front and rear baffle/hakama repair/paint saran frame reinforcement painting/net replacement, batch polishing unit maintenance (high frequency magnetic circuit/in-gap cleaning/center adjustment diaphragm gap indirect attachment) ATT cleaning unit detachable)
Accessories: saran net
Main specifications: 2 way, 1 speaker, bass reflex system, floor type specification unit 3828, crossover frequency, 1 kHz, output sound pressure level, 91.5 dB, 8 ohms, dimensions W660 x H990 x D370 mm, weight 43 kg/book
Scarce! Altec's variable frequency mono channel divider! Deteriorated parts, including 10 deteriorated capacitors, have been replaced! The frequency can be changed by opening the front panel, and it is compatible with crossovers from 80 Hz to a maximum of 10,000 Hz, so a very wide range of settings can be made. It features a clear tone typical of Altec, and is a must-see for multi-system users using the company's amplifiers. The input/output is a lug type only, so please make your own RCA cables, etc. (SASAKI Shota)

Accessories: none
Main specifications: primary impedance 600 Ω (150 Ω split) secondary impedance 600 KΩ (150 kΩ split) primary inductance 70 H W140 × H110 × D100 mm 1.8 kg (actual measurement, not including protrusions)
Maintained. This is the X-2000R, the best model in the X series. It boasts performance that surpasses the X-1000R, such as a CA (cobalt amorphous) head and a newly designed equalizer amplifier, and you can listen to damped sounds with little noise due to the DBX installation. There are stains and bumps on the exterior. Serial 20066 (Tamura Eiji)
