Have a pair of 8" Bullet Hollowpoint 770 HLCD speakers with 2-7/8" wakeboard tower mounts. I had 4 of these but only put 2 on my pontoon boat, and everyone in the boat thinks it's too loud. 

These project sound out to about 80 feet. Perfect for wakeboarding or other watersports, I like them because you can actually hear the music loud and clear outside of the boat unlike normal speakers that are installed in the boat and you amp the hell out of them and can't really hear them once you're off the boat and in the water. 

These are some of the best HLCD's available. They handle I believe 175 watts RMS, I'm running a pair with 145 RMS and they are plenty loud. They are HEAVY about 15 lbs apiece. Check them out at bulletspeakers.com you'll see they're $900 a pair.

They come included with soft black poly/lycra covers to keep the elements off them while not in use.

So far the offers coming in are being automatically declined because they are much lower than the threshold which I will consider. People, if you want wakeboard tower speakers for $250 you can get them, but they WON'T be HLCDs. Please consider the fact that these are $900 speakers and are worth that new. These work perfect but cosmetically they are 8.5/10, hence the low price.
