SB Acoustics SB17NRX2L35-4 6" Norex Natural Fiber Cone Large-Magnet Woofer- 171mm- 92dB- 4 ohm
Spec Sheet PDFNew from SB! These woofers have an extra large magnet for strong output and low Qts. SB recommends use in a small sealed box with DSP or for Home Theater.
· Vented cast aluminum chassis for optimum strength and low compression
· Proprietary cone material with natural fibers made in-house
· Soft low damping rubber surround for transient response
· Non-conducting fiber glass voice coil former for minimum damping
· Extra large motor with extended copper sleeve on pole piece
· Vented coil former
· CCAW voice coil for reduced moving mass
· Long life silver lead wires
· Vented pole piece for reduced compression
This is an exciting new addition to the SB17NRX family and notably features a large 120mm motor system. This increases sensitivity and dynamics are presented with more scale and punch. Be aware the larger motor will not result in more/deeper bass in a conventional bass reflex alignment as is dictated by the lower electrical Q of this larger motor system. Very compact sealed enclosures augmented by DSP will suit well, as will other applications where sensitivity and output are prioritized, for example home cinema with separate subwoofers. Transmission line and horn loaded enclosures may also be considered for this driver. Available in 4 and 8 ohm.Some Sample Boxes:
- 4 liters sealed and stuffed: F3= 153 Hz.
- 6 liters vented with minimal damping: Fb about 53 Hz, F3=82 Hz (1" x 3.9" could be tried for this small bass reflex)
