Used these to replace SRM 450v2's which I have used for years.Better clarity and all round better sound. Easy to set up. They are lighter also which is a big bonus as a mobile DJ. There is probably better speakers out there but not at the price you can get these for.

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.

Just purchased a pair of the Mackie SRM450 V3 12" speakers for one of our new DJs. I will be after a pair myself after trying them out them myself. I ended up using them on several gigs before reluctantly handing them over to our new DJ as they sound so good.

Great for any size venue big or small. We use them in a medium sized hall along with the two subs and the sound is amazing.

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.

Excellent sound, easy to handle

really like these, as a long term user of the V1 series, in a side by side comparison, they perform in a very similar (If Not Slightly Better) manner, but that is with 11 year old drivers in the original V1's.. :-)

Great speaker, dose what it says on the tin!
