I've been drawing, designing and building concert speakers, mid, hi's and full range speaker boxes for over 40 years, and if nothing else one thing I've learned is not to chase name brands of any kind. There are some little known brands like mine JAHsound that have no choice but to work and fight twice as hard to make great products that are even as good or better than the commercial brands. So, I'm always willing to give the lesser known brands a try, and because of that I've bought and tested hundreds of different brands of speakers over the years and can vouch for our brand of woofers that are on the cutting edge of technology. They will meet or beat your expectation and I can say that with full confidence, All hell break loose when these start to play, they are Awesome! NEWLY DESIGNED, Waterproof, Rugged, Strong and take a pounding all day and night.
