Heavy Duty 3-Way Sealed DIY Speakers (22kg/Each) + Premium Capacitor Upgrade Kit Included
Selling a massive pair of heavy-duty, reference-grade 3-way sealed box DIY speakers. These speakers were originally custom-built by a professional engineer 20 years ago without a final cosmetic finish to save on costs. I have completed the final cabinet finish myself.
They sound incredible as they are and easily outperform expensive modern compact speakers, offering effortless scale, massive full-range authority, and natural midrange detail. The only reason I am selling them is that they are simply too big for my small 3x4 meter room
Tweeters: TVM ARV-104-03/8 units for detailed, non-fatiguing highs.
Midrange: TVM ARP-150-00/08 dedicated mid drivers.
Woofers: Dual TVM ARN 226-07-04 bass drivers per cabinet in a tight, sealed alignment.
Crossover: BS Acoustic CN 01-3-12/8 (8 Ohms, 150W RMS / 300W Peak, 12 dB/Oct).
Bass Extension: True full-range down to 30Hz up to 18,000 Hz with high 91dB efficiency
Included €70 Audiophile Upgrade Kit (Brand New):
The speakers sound amazing as-is, but I am including €70 worth of brand-new, high-end upgrade components that I bought for them. These parts are loose/not installed, giving the new owner the perfect opportunity to upgrade the internal crossovers and terminals to a true high-end level:
2x Mundorf E-Cap BR100 raw audio capacitors (33 uF 100V)
2x Jantzen Audio Cross-Cap premium film capacitors (15 uF)
2x Jantzen Audio Cross-Cap premium film capacitors (3.9 uF)
2x Jantzen Audio Cross-Cap premium film capacitors (3.3 uF)
New high-quality replacement speaker terminal/binding posts
Weight: Massive 22 kg per speaker cabinet.
Front Baffle: Thick 4.5 cm front baffle panel to completely eliminate resonance.
Internal Bracing: Every corner is heavily reinforced with solid wood bracing blocks.
Protection: Comes with protective custom speaker metal grills and a set of heavy-duty metal floor spikes and floor pads. Perfect setup for homes with pets or kids
The value of the heavy-braced wood cabinets, TVM drivers, and the €70 extra upgrade parts easily exceeds this cost.
Currently connected to a high-end Primare A30.1 MK2 amplifier and Denafrips Ares II R-2R DAC.
Serious buyers are highly welcome to come for an audition to hear exactly how massive and clean they sound before buying!
