Important For Hot Tub Users These speakers are designed to withstand splashing and rain, but not submersion. Submersion will dramatically reduce the life of these speakers. If you have a situation where the speakers are partially submerged when the hot tub is occupied, you should consider reducing the amount of water in your spa.

Replaced two old speakers. The radio hadn't worked for a few years and to my surprise the new speakers brought the radio back to life. Great sound!

Very pleased with these speakers! Exterior speaker replacement for my 2014 Open Range Roamer 5th wheel trailer RV. Replaced the "blown" 25 watt Magnadyne exterior speakers with these 50 watt Magnadyne speakers. They fit perfectly and sound great for the size.

These are not speakers that will blow you away, but were an exact replacement for my hot tub. Much cheaper than what the hot tub dealer wanted for them!

Rock the Boat was very friendly to work with on placing the order. These speakers do the job of replacing some worn out speakers in my hot tub. They are not top of the line, but you get what you pay for; and the damp environment of a hot tub is not the place for high dollar speakers; so these work fine for listening to low/medium volume music while relaxing in hot water!

Using them on a magnetic mount tank bag, powered by a 40 watt amp on my '98 Guzzi. Sound is good. Not great. More distortion at higher volumes. Better than the 40 watt OS that came with it. Good company to do biz with...highly recommend.

I bought these speakers as replacement for my hottub and they didn't even last a year. I wouldn't recoment purchasing these speakers. This is the second time I purchased these speakers and each time they died in last then six months. CM

I have purchased both the WR40W and WR42B for my hot tub (same speakers, just different power and color) and they both lasted maybe 3-5 months before failing. They may be a cheap alternative for a boat but they stink for a hot tub, don't waste your money.
