JKent 0 Report post Posted January 24 Welcome to CSP Those are not classic New England KLH speakers and my advice would be to watch for some earlier models from Cambridge MA. Every seller says his speakers sound fantastic or amazing. Buyer beware. -Kent Quote Share this post Link to post Share on other sites
