Price Reduction [Renovated Item] Retro Box YAMAHA 5inch Bass Reflex System

◆Overview
This is a bass-reflex system with YAMAHA 5-inch full-range units housed in retro cabinets. The well-made cabinets have resulted in a well-balanced and excellent system with the 5-inch (12cm) units.

◆Renovation Details
1. Exterior of the main unit:
The cabinets are made of high-quality veneer with no scratches. They were cleaned with a neutral detergent and then meticulously polished. The surface was smoothed with #400 sandpaper, followed by oil sanding with #400, #800, #1200, #1500, and #2000 grit sandpaper for a polished finish.

2. Interior of the main unit:
High-quality sound-absorbing material, repurposed from another source, has been attached to the inside of the rear cover. It is attached with bolts and nuts through a through-hole, allowing for repeated removal and reattachment.
The newly constructed baffle is protected with a brown coating on the back and features a bass-reflex port (φ5cm x L=4cm). The resonant frequency is approximately Fd = 100Hz.

3. Rear:
The original rear panel was made of 9mm plywood and had direct cable output. It has been modified to an embedded terminal with banana plug-compatible posts. All mounting screws have been replaced with new stainless steel screws.

4. Units:
- Full-range unit: Cone type, 5-inch (12cm), 8Ω (YAMAHA manufactured - markings were unreadable)
Overall, the units are clean, though there are slight stains on the cone surface. The edges are flexible, high-quality cloth edges, and are in excellent condition. The aluminum die-cast frame is robust and well-constructed to prevent unwanted vibrations.

5. Dimensions:
W=21.0cm, H=34.0cm, D=23.5cm (including rear protrusions and grilles)

◆Sound Characteristics (Personal Opinion)
An excellent full-range speaker with a smooth playback frequency range.
- Low frequencies:
Thanks to the bass-reflex effect, the bass is high-quality and has a sense of depth. It feels like it outputs more than a 5-inch speaker.
- Mid and high frequencies:
The connection with the low frequencies is good, and there is no lack of clarity up to the high frequencies. While not flashy, it offers a high level of sound that is not fatiguing to listen to.
