SB Acoustics SB23NACS45-8, 8" Aluminum Cone Woofer

Spec sheet: SB23NACS45-8 PDF

  • 8 ohm
  • Geometrically reinforced aluminum cone
  • rigid cast frame design for minimal reflections
  • rubber surround
  • shorting ring to reduce distortion
  • shallow 3-1/8" depth
  • good choice for either sealed or vented boxes

Box recommendations:

Sealed box of 0.5 cubic feet with 20% filling for 3dB down at 60Hz
Sealed box of 0.75 cubic feet with 20% filling for 3dB down at 56Hz
The bigger sealed box should perform better.

Vented box of 2.0 cubic feet with 10% filling with 2" diameter vent by 4.75" long for 3dB down at 31Hz
Vented box of 1.3 cubic feet with 10% filling with 2" diameter vent by 6" long for a 3dB down at 36Hz
The smaller box would handle more power.

Bandpass box
0.65 cubic foot sealed chamber
0.75 cubic foot vented chamber with 3" vent diameter by 4.25" long
The box is the crossover and it would roll off at 35Hz on the low end and 100Hz on the top end. 
Sensitivity is boosted by 3dB to 90dB in this box, plus no crossover is needed.

Advanced Features:

  • Soft low damping rubber surround for improved transient response
  • Geometrically reinforced aluminum cone for improved break-up control
  • Shorting ring in motor system for reduced distortion
  • Vented pole piece for reduced compression
  • Vented cast aluminum chassis for optimum strength and low compression
  • Shallow design
  • Non-conducting fibre glass voice coil former for minimum damping
  • CCAW voice coil for reduced moving mass
  • Long life silver lead wires

Amazing and not just for the price.
I have a personal hatred for 8 in woofers because they usually run out of steam long before you arrive at satisfying bass. These were some of the best I have heard and were a total surprise. I normally use expensive revelator drivers, but this really made a budget build sound like a $20k pair of speakers.
