    Rated 5 out of 5 by from Great Sounding Speakers 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.

    Rated 5 out of 5 by from Excellent speaker 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.� Our new theater made it necessary for the orchestra pit to be off stage behind the cast and we used this one on a loop from one of the main speakers so the orchestra, and most importantly the conductor, could� hear the singers.� We had clean, accurate sound reproduction, and all went well.

    Rated 5 out of 5 by from Powerful with full range of sound 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.

    Rated 5 out of 5 by from Great Speaker for a Great Price I use these speakers for political and corporate events, very high end, high stake events. If something goes wrong with sound, we lose a client. These Mackies put out great sound, they are durable, light weight and inexpensive. What else could you ask for?
