Hello!!
Has anybody heard of the Bose 802s? Expensive but.....well, I would not trade them for anything out there. Light, portable, excellent warranty, never needed more than 50% volume, plenty of bass response. Two of them will handle the average gig. 4 of them will handle an outdoor concert. Best I've heard for vocals. Don't let the size of the horns fool you. you wont believe the amount of bass response they put out. It's amazing!
Pricey? yeahp! but will pay for themselves in the long run. And if you ever decide to get rid of them, (couldn't imagine why?) they bring the best resale price on ebay. Check it out!, you may find a great pear used(not cheap though).
By the way, has anyone been on cruise ship lately? I've been on 5 cruises in the last 4 years, and all I've seen being used on their "padded" lounges are Bose 802s, if that means anything.
Regards,
Mario
