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.

Product Research

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.

Customer Q&A

5 questions already asked

Q
Can these speakers handle being bounced around on a wakeboard tower? Will they hold up to heavy rain storms? Thanks
[ David  Jul 03, 2019 ]
1 answer
A
Hi David, thank you for your question. We do not show an IP rating for these speakers. They are weatherproof, but since the IP rating isn't listed, it would be hard to say exactly what they are designed to withstand. You may want to reach out to the manufacturer at 800-999-1236. The housing materials and clamping systems however are designed to withstand outdoor use, so they will be ok for use on you Wakeboard Tower.

Q
Are these blue tooth compatible or do they need a head unit to operate?
[ Ed  Jun 03, 2019 ]
1 answer
A
Hi Ed! These speakers will need a power source. If you don't have a head unit, you would be able to power these up with a Bluetooth amplifier! If you need any assistance with picking out the items that will work best for you, feel free to get in touch with us in our online chat service, or by phone at 1-800-324-9695. We'll be happy to help!

Q
Do these come with amps?
[ Grant  May 14, 2019 ]

A
They do not, you will need an amplfier to power them.

Q
I know these are made to mount on a round bar,but will they fit around a square tube on a golf cart roof support?
[ Chuck  May 12, 2019 ]
1 answer
A
This is something we have not tested. Technically, if the diagonal of the bar's cross section is in between 1.5-2" the mounting clamps will make contact with the bar, but only on the corners of the bar. I'd be concerned about that not being enough contact with the bar to hold the speaker in place My Bio: https://www.crutchfield.com/bio/Paul

No we only carry those in black. Here is a list of all the white, marine, tower-style speakers we carry.
