Generally speaking, I am willing to pay a few extra bucks for quality and extra durability. However, in marine radios and speakers I have found that the high end stuff does not last longer, nor is it really all that much better.
My boat initially Kenwood kfc-1652mrw speakers. They actually sounded pretty good for their size, but lacked any punch on the low end. It was time to replace them, so this time I went with something that hopefully had more bass. These Boss speakers have a larger magnet and the cone seems larger, so I gave them a shot.
Installation is pretty straightforward, and you shouldnt have any surprises there. The speakers seem good enough to last in the marine environment. These needed a bigger cutout then the Kenwoods they replaced, but really not a big deal for me.
Overall, I am happy with the sound. The sound is not as good as the Kenwoods, but good enough. The Boss speakers do have way more low end grunt, but less mid and high. The Kenwoods also sound clearer at all volume levels, and sound was consistent even at high volume levels. It seems the Boss need a higher volume setting before you can really start to hear them. The mid volume range was good. At high volume, they do get a bit distorted. But, this was only really a problem near maximum volume.
Overall, I am happy with the product. If they last me 3 years, I will consider this a great deal and buy them again. I would never buy Boss for my car, but in a boating setting where they will get wet, salt, blood and guts, etc., they are fine.
