Crescendo Audio Bass Clef BC-4K 4000W RMS Monoblock Amplifier

As some enthusiasts have already heard through the grapevine, it is our pleasure to announce the new BassClef series.

The current Bass Clef series has had a hell of a run since 2011, but with all good things, it is time to raise the bar once again.

The 2018 Bass Clef models range from 4kw to 17kw. The first models to hit the market will be the BC-4k and BC-6k, followed by the 8k, 13k and 17k.

All new BC amplifiers utilize a newly tooled Crescendo heatsink and revamped circuit boards that stay true to our standards, with even higher power-per-square inch and resilience than before.

• • Stable down to .5 ohm on sufficient electrical.
  • Up to 17v capable.
  • Newly designed, custom tooled, proprietary Multi-piece Thermal optimized Heatsink with patent pending interlocking slide-out CNC engraved top plate.
  • 2 stage copper anodized Top Plate that is easily removable for those who want to color match to their show quality installs.
  • Silver plated & hard-wired Tiffany RCA inputs
  • 2 sets of oversized 1/0 Power/Ground Inputs for efficient current transfer.
  • Dual 4 gauge Speaker output terminals! Which each terminal containing two outputs contains the same polarity for extreme ease of use! ( + + ) & (- -)
  • Overbuilt Power supply with heavy copper traces and Military spec PCB/heavy duty standoffs for extreme vibration resistance.
  • Handwound heavy duty transformers & inductors to insure no shorting of the windings from escessive vibration.
  • Manufactured using some of the highest quality and most reliable electrical components, with many 3% tolerance components throughout.
  • Full 4-Stage Intelligent protection Circuitry
