These extreme subwoofers are built to exceed today’s high quality competition standards. Each subwoofer utilises three important features used in today’s best subwoofers: dual voice coils, double magnets and cast frames.
Offers around $120 Some of the design features include: - 4mm thick non-pressed coated paper that can withstand huge excursions with minimal flex or break-up. - The magnet: Two 1.41Kg totalling a massive 2.82Kg. - The basket: Thick heavy duty cast aluminium with zero flex, even under the most horrendous driving conditions. - The backing plate: 19mm thick (most woofers are, on average, 8-10mm). This gives excellent linearity. - Pole piece: A flared vent at the rear increases air movement to cool the voice coils. - Dual voice coils: Give you 3 different wiring options to best suit your amplifier. Dual 4-ohm voice coils give you greater system wiring flexibility. Connect the voice coils to achieve an impedance that ideally suits your amplifier. - Parallel voice coil mode: Wiring the voice coils in parallel, to present a 2 ohm load, allows you to extract maximum power from a high-current, 2 ohm stable, amplifier. - Series voice coil mode: Wiring in series gives each speaker an 8-ohm load. If you wire the two 8 ohm subs in parallel, you get a 4 ohm load that’s suitable to utilise on the bridged output of a 2 channel amplifier.

Bump:
Anyone else? This is a good quality sub and dual voice coil provides good flexability with wiring etc... I'll take $150 including postage in Vic

I have one remaining, so you would need to purchase the other one new if you were looking for 2.
I can deliver, allow $15 delivery

Are these still available new? was looking on the jaycar website but couldnt find them, however, i think that is because they charge you for the catalouge and dont put the full range on the web

I am informed they are but if you were intending on purchasing one from me and then getting others you would need to check.
