The SRM450s are incredible speakers. Two of these can easily fill a very large room. We have used them to supplement in ceiling house speakers for 300 people. Great sound for both music and vocals.

We bought this Srm450 because we had one of the earlier models we used to send piano to the cast on stage because they couldn't hear it from the pit and were very pleased with it and its trouble free use.

I'm a Mobile DJ. Mackie SRM450v3 is an easy set up. Plug in and play simple. The SRM450v3 has unbelievable sound, incredible base, very reliable. It's only 32 pounds easy to carry. Stylus case and rugged design. If the SRM450v3 take a fall you know it going to survive. 1000 watts amazing!!!

These puppies Rock! The coverage these speakers get are amazing. Loud and clear.. Will be buying 2 more to add to my 2 current as well as a SRM 1850. Definitely worth the money. I also purchased the Mackie covers. They come with pockets which are great to store your cables and power cord.
