8 bits of bun

Real subwoofer


Description:

The rumbling engine of my HT system, capable of going as low as 15HZ without issues.

Can generate local earthquakes with clean sound and unhearable distortion.

It has a 120L braced enclosure for lots of low frequencies.

Crossed at 40hz with the front, 40hz with rear, and 120hz with height speakers.


Specifications:

82DB @ 1 watt, 1 meter
220w rms amp (Behringer A500)
Reconed Shark XSUB12 (thanks to FixMySpeaker by PSI)
15-120hz frequency range


Additional notes:
  • Used 22mm mdf with  30x30mm wooden poles for internal braces for the enclosure.
  • 2 layers mdf 22mm mdf for the front baffle (44mm total).
  • The enclosure has sheets of 60mm thick internal dampeining along the walls.
  • Slot ported to around 15HZ, but can't go this low without changing the driver for a long throw one..
  • The current 200w integrated amplifier is completely dead.
