New Paper cone sub from SB! Low resonance, reinforced cone and high power handling make this a versatile subwoofer driver for home or car.

Nominal Diameter: 34cm
Impedance: 4 ohms
Power Handling (RMS): 300 W
Frequency Response: 18 Hz

  • Long stroke design
  • Linear high stability suspension
  • Low damping rubber surround
  • 3’’ copper voice coil
  • Non-conducting reinforced fibre glass coil former
  • Very stiff hard paper cone (made in-house)
  • Vented cast aluminium chassis

Possible box alignments:
  • 1 cubic foot sealed for f3 of 40Hz and f6 of 30Hz.  A little bass boost on the amp and you have a sealed box subwoofer.
  • Your normal vented box alignments would have too long a port in too small a box.  A modified extended bass shelf could be used as 2.5 cubic feet with a 3" diameter vent by 12" long for f3 of 21Hz.

Great for a sealed sub!
I had looked for a long excursion driver to retrofit an old M&K V-90 sub, and chose this SB Acoustics SB34SWPL-76-4. I did have to open the front baffle to accept the larger frame of this driver, but it was SO worth it! It's the cleanest, most distortion free driver I've ever used. Mated to a 250 watt DSP controlled amp, it drives this in a 1.6 cu ft box to unreal levels and never sounds anything other than glorious!
