I've had the K-10 PA speakers by AAD for several years now. They've done a great job for family outdoor gatherings, parties, karaoke, and neighborhood block parties. Just over a year I've used them in my home theater set-up (front stage of course). Does the job well and for karaoke applications too. The K-10's retails for $800.00 and the K-8 $600 If any of the members have an interest please let me know. I have a direct account with them. Please visit the link below.
