DRIVE UNITS BY MANUFACTURER:
SB17NBAC35-8
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.

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 !
