About the Boss Audio MRWT40

Small tower speakers with big power
Small tower speakers with big power
These high-performance MRWT40 4" tower speakers from Boss prove that big sound can come from small packages. Designed for marine and off-road use, these rugged, powerful speakers can handle up to 100 watts RMS each, so your small boat, ATV, or golf cart will really rock.
Made for marine and off-road use
Like all Boss speakers, these wake tower models bring the noise, but they're also built to last. Durable, lightweight polypropylene cones and 1" tweeters are housed in rugged, UV-resistant baskets, while the internal components are sealed for protection against moisture. These speakers are plenty tough enough to stand up to the rigors of outdoor life. The mounting clamps are built to last, too, and they'll fit 1-1/2" to 2" roll bars.

Features
Overview: The Boss MRWT40 weatherproof marine speakers are designed to provide high-quality sound for both waketower and UTV roll-cage applications.
Enclosure: Both of the included 2-way speaker enclosures features a 4" woofer, constructed of a polypropylene cone with rubber surround, and a coaxially mounted 1" dome tweeter, all mounted in a weatherproof ABS enclosure that's designed for marine and powersports applications.
Specifications: Each MRWT40 speaker carries a 94dB sensitivity rating and is capable of handling 200 watts RMS (400 peak) with a frequency response of 130Hz - 20kHz. Note: For best performance, Boss recommends applying a 120Hz high-pass crossover to the input signal.
Mounting: The MRWT40 speakers feature built-in mounting clamps for attaching to a waketower or ATV/UTV roll-cage tubing. Both mounting clamps allow the speakers to be attached to tubing ranging from 1-1/2" to 2" in diameter. Rubber strips are included to help protect the tubing's finish as well as provide a firm grip for the mounts.
