🔊 Klipsch R-51M Bookshelf Speakers — New, Factory Sealed
The Klipsch R-51M bookshelf speakers deliver the signature Tractrix horn-loaded Reference Series sound in a brand new, factory-sealed package — with class-leading 93 dB sensitivity that outperforms every competitor in this price range. If you’ve been waiting to get into the Klipsch Reference lineup without compromise, this is your opportunity.
🎺 Klipsch R-51M Bookshelf Speakers — Tractrix Horn-Loaded Performance
At the heart of the R-51M is Klipsch’s proprietary 90×90 degree Tractrix horn mated to a 1-inch aluminum diaphragm LTS (Linear Travel Suspension) compression tweeter. The LTS design keeps the voice coil in the gap at all times, minimizing distortion, while the Tractrix horn focuses high-frequency energy precisely toward the listener for exceptional detail, dynamics, and that unmistakable Klipsch front-row energy. CNET praised the R-51M’s “exciting rock and roll sound” and excellent build quality — and audiophile communities consistently highlight its wide, deep soundstage that brings recordings to life at any volume.
🏺 Copper-Spun IMG Woofer — Articulate, Efficient, Distinctive
The 5.25-inch copper-spun IMG (Injection Molded Graphite) woofer delivers articulate midrange and well-defined bass extending down to 62 Hz. The rear-firing Tractrix port applies the same horn geometry to the bass reflex design for maximum efficiency and reduced port turbulence — a detail most manufacturers skip entirely.
🎨 Build Quality & Aesthetics
Low-profile magnetic grilles with exposed copper-toned fasteners for a polished, modern look
MDF cabinet wrapped in black textured wood grain vinyl with clean, contemporary lines

Onkyo TA-2040 Cassette Deck – Silver, Japan, For Parts/Repair
Sold as-is for parts or repair: multiple faults, not covered by our warranty, not eligible for trade-back, all sales final. What it is, is a 1980 Japanese-built two-head deck with a sendust head, full-logic transport, FG-servo motor and Dolby B — not economic for our bench, and a completely different arithmetic if you have a soldering iron.

Does not power on. Sold as-is for parts or repair, with no warranty and no trade-back. Cosmetically it presents very well, with no significant marks to the faceplate or cabinet. Working, it was a 100-watt-per-channel 6.1 receiver with Dolby Digital EX, DTS-ES and a full set of 6.1 pre-outs. 32.7 lbs of bench project.
Yamaha Q2031 Dual 31-Band Graphic Equalizer – Made in Japan, 2U
Thirty-one bands per channel on ISO third-octave centres, 20Hz to 20kHz, on two fully independent channels — fine enough to pull a single room mode down without touching what sits either side of it. A range switch halves boost and cut to ±6dB for careful work, and the high-pass filters sweep from 20 to 200Hz. Balanced XLR and 1/4-inch throughout, 2U rack. Condition good.
Maxell UR 120 Blank Cassette – Normal Bias, Sealed
A hundred and twenty minutes of Maxell UR, normal bias Type I, still in its factory wrap. Sixty minutes a side is a full album with room left over. Type I is the default setting on every deck ever made, so there is nothing to select, and it is the correct tape for the 9.5 cm/s speed on a two-speed machine. Unopened, unused.
