We will try to keep these in stock, but many times these items are being drop shipped to our facility for inspection. We will then send the product on to you. This could delay the time it takes to receive the items by 5 days to 2 weeks. We have decided it was best to make sure it checks out OK before having it go out to you. Contact us for ETAs before or after purchase, because we always have them coming in.

18" Professional Subwoofer 4 Ohm

This 18" professional woofer features 3,000 watts of continuous program power capacity, thanks to its 4" split winding copper voice coil. A frequency response of 30 to 1,000 Hz and 57 mm of peak-to-peak excursion (before damage) combine to make this one of the top woofers in its class. The 18TBW100-4's double silicone spider with optimized compliance keeps the driver controlled, while the ventilated voice coil gap reduces power compression. Low distortion is achieved by using an aluminum demodulating ring in the driver's magnetic circuit. Great performance is realized in vented boxes as small as 7 cu. ft.
