While aiming for a stylish upgrade in Ver.2, I disliked the duct area that looked like an afterthought. So, in Ver.3, I transformed it into a ribbon tweeter-style duct using metal mesh, reminiscent of the old days. While mesh isn't ideal for ducts, the creator, prioritizing appearance, put looks first. Just like my older sister, who prioritizes looks over substance, there are many misses. Since I put an 8cm full-range speaker in a mini surround box, there's no way it should produce low frequencies. However, I forcibly managed to pull out some low-end. I applied Cemedine Concrete to the full-range speaker cone to add mass. Efficiency drops significantly, but low frequencies increase. Or rather, perhaps the mid-high frequencies drop, making the lows relatively higher? This is a technique used by the late Nagaoka-san. However, the white color of the Concrete would look out of place as is, so I cut and pasted artificial leather in a circular shape. I left the center part uncovered to avoid losing high frequencies. Next, I made it a bass reflex system. I drilled holes in the small box area where the tweeter used to be. I installed a 7cm long duct. The resonant frequency (fo) is around 100Hz. Lowering it further would be futile. Dimensions: Height 168mm, Width 105mm, Depth 135mm. The speaker unit is made by Pioneer. The enclosure is a modified DENON SC A11R surround speaker. So, what about the sound, the low frequencies? The voice of the male news announcer sounds natural. With this size, voices often sound unnaturally high-pitched, but this speaker sounds completely natural. If it sounds this good, it can handle music too. Click here for the manufacturer's site
