SB Acoustics SB17NBAC35-8 Aluminium Midwoofer

SB Acoustics logo

UK STOCK ITEM

The SB Acoustics SB17NBAC35-8 is a 6 inch 8 ohm midwoofer featuring a black aluminium cone and a vented cast alloy chassis. The rigid cone has pressed geometric reinforcement troughs that suppress ringing / breakup modes offering extended pistonic action, this results in a much wider usable response than normally found with metal coned drive units.

Also available in 4 ohms: SB17NBAC35-4.

Key Features:

  • Vented cast aluminium chassis for optimum strength and low compression.
  • Geometrically reinforced aluminum cone for optimum piston operation and reduced break-up.
  • Soft low damping rubber surround for improved transient response.
  • Non-conducting fibre glass voice coil former for minimum damping.
  • Extended copper sleeve on pole piece for low inductance and low distortion.
  • CCAW voice coil for reduced moving mass.
  • Long life silver lead wires.
  • Vented pole piece for reduced compression.

Basic parameters:

Resonant frequency (fs) 31.5 Hz Nominal impedance (Zn) 8 Ω
Mechanical  Q factor (Qms) 4.1
DC resistance (Re) 5.7 Ω
Electrical Q factor (Qes) 0.38
Max power handling 60 W
Total Q factor (Qts) 0.35
Sensitivity (2.83V/1m)
86.5dB
Equivalent volume (Vas) 45L Chassis diameter

Excellent Drive units

Very impressed with these drivers which I think are great value for money. They are very revealing and I am hearing details in music that I have not heard previously. Bass response is very good (I have them in a 24l transmission line enclosure) and they go deep. It's an aluminium cone so the break up above 6khz needs squashing down, but easily achieved with the crossover design and they integrate well at a 2.5khz crossover frequency.

Thanks for the review Matthew !
