Designed for both indoor and outdoor use, it features a durable rubber surround and polypropylene cone for weather resistance and longevity.

## Description

From the manufacturer Medium range: polyester injection Polyurethane, classified as a polymer, is a strong, flexible and durable manufactured material that can replace paint, cotton, rubber, metal or wood in thousands of applications in virtually every field. It can be hard as fiberglass, soft as upholstery foam, protective as varnish, elastic as rubber or sticky as glue. Wrap – Rubber Rubber is a synthetic material (man-made) and is valued for its chemical inertia, air impermeability, and the ability to withstand or resist exposure to many types of weather fronts. Rubber has applications from sports equipment to auto parts, the medical industry and more. We use them for the frames connecting the cone to the basket. Voice Coil - Aluminum One of the most abundant elements on earth, aluminum is notable for its low density and its ability to resist corrosion. It is not magnetic (does not have magnetic properties) and does not light up easily. This solid material has the ability to operate under stress in both high voltage and high compression environments. Specifications 4 Inch Three Way Indoor/Outdoor Box Speaker Bass Speaker: 4" Tweeter: .79" Maximum power: 100 watts Effective Power: 40 UK Nominal impedance: 4 to 6 ohms Frequency response: 100Hz - 20kHz Sensitivity: 85dB 2.83v @1m

Review: Perfect for indoor RV/Travel Trailer Use. - I own a 2015 KZ 20RBS with a Jensen Stereo/DVD player and have been disappointed in the sound of the system since it was new. The A-channel are the two cheapy inside ceiling mounted speakers and the C-channel are the outdoor speakers. Channel B was unused. I decided that I wanted to fix it where the TV would work through the stereo (The DVD would work through the speakers but not the TV) Head scratch ?? Since I was working with the system I decided that I would utilize Channel B and make the sound more full. Enter the BOSS 4.3" speaker set !!! I just got done installing them in the trailer and they sound amazing. I have a pretty good ear since I have been a musician for years and these little guys have an incredible frequency response with crisp highs full mid-range and surprisingly deep responsive bass. I couldn't be happier especially for the price. These speakers are a perfect combination for the Stereos that come in most Travel Trailers. They are well made and super easy to mount. ****Note I'm a person that likes to listen to music and movies at a medium volume level so I'm not sure how they would hold up if "cranked up". They are rated @ 200 watts but I've always only fed speakers half of their rated amount.
Review: Great sound. - I bought these speakers to replace the ones on the sundeck of my boat that had started to sound flat. They sound great and were easy to hook up. I found them a good value for the money.

### ⭐⭐⭐⭐⭐ Good Product so far.
*by D***1 on 16 April 2018*

Sound is good. They do tend to overdrive when the volume is increased but it is very loud at that point. I bought them to use outside and haven't beanpole to do that yet due to weather. Inside they work great
