Latest and Greatest From Mackie

Mackie's gone the extra mile for you with the SRM450v3 active speaker. The newest generation of SRM speakers gives you 1000 watts packed into Mackie's rugged, lightweight molded enclosure along with powerful digital audio processing to match. An on-board mixer, one-button tone shaping, feedback elimination, and thru-put signal routing options makes the SRM450v3 the most powerful component of your rig but stays convenient and easy-to-use. Lighten your load-in, update your PA, and let the speaker do some of the work, add a Mackie SRM450v3 active speaker to your rig!

Mackie SRM450v3 Active Speaker at a Glance:
  • Why is the SRM450v3 for you?
  • On-board processing keeps your load light
  • Great sound wherever you need it
Why is the SRM450v3 for you?

Having an active speaker or two on hand is always a good idea for a gigging musician and they don't get much more versatile than the SRM450v3. You're always coffeehouse-gig ready with an on-board mixer that has two channels of Mackie's Wide-Z preamps to handle your mics and instruments and RCA inputs for tracks or music between sets. If you're called to play a Saturday with the band at the local pub (or for rehearsal), you won't have to worry about walking into a bad monitoring situation. Do what Sweetwater players do and take your SRM405v3, its perfectly designed 'monitor-wedge' cabinet and one-button monitor mode audio processing have you covered.

On-board processing keeps your load light

The SRM450v3 does all the work that your old front of house rack took care of. The one-button High-Definition Audio Processing mode selection applies processing that makes the speaker bump for DJs or boosts vocals for your solo gigs. The automatic Feedback Destroyer keeps the squeals out of your show and you don't have to chase EQ settings all night. Mackie's proprietary Smart Protect DSP keeps your speaker safe and reels you back in if you get pushy with the master fader.

Great sound wherever you need it

With all the awesome there is to the SRM450v3, you almost forget that it's a great-sounding speaker too! The precision 2-way crossover feeds a 12" neodymium woofer and a 1.4" titanium dome compression driver giving you exceptional clarity and performance while keeping down the weight. The rugged molded exterior is road-ready for gigs and lends to the sonic characteristics that make the SRM450v3 so desirable. In fact they sound so good, Mackie designed hang-points into the exterior of the cabinet so they can be flown for installed PA systems.

Mackie SRM450v3 Active PA Speaker Features:
  • 1000W system power with 12" high-output LF driver and 1.4" titanium dome compression driver
  • High-Definition Audio Processing for professional sound with unmatched clarity
  • Precision 2-way crossover, driver time alignment, and phase correction for easy set up no matter the venue
  • One-button speaker mode selection for application-specific voicing, get the sound you need
  • Eliminate feedback with one-button automatic feedback destroyer
  • 2-channel mixer features dual Mackie Wide-Z inputs to easily handle your mics or instruments
  • Includes stereo RCA inputs for easy connection to MP3 player or drum machine
  • Smart Protect DSP protects your speakers from damage when you get loud
  • Monitor angle and voicing mode for easy stage monitoring
  • Great for install or portable systems
  • Weighs in at only 37 pounds!
Gig tested and musician approved, Mackie's SRM series active loudspeakers get better with every 'v'!

Reviews

Well worth the wait
Bought these and they were on back order. Waited 3 months. Definitely worth the wait. They sound soooo clear. Haven't used them for a guy yet but at practice they are awesome. Thanks for the awesome deal and great customer service

Really Old Mackie SRM 450's
I bought 2) SRM 450's, the very first ones ever made some 25 plus yrs ago. Been so long can't remember exactly. Used them most weekends for years. Then I stored them for yrs., then dug them out again and are still using them again. Put new speakers in them yrs. ago. Never any problems show after show. Killer show last week and they still sound GREAT! I may buy a couple more, use the old ones for practice. Oh, our band has a new Mackie Onyx 16 on order! Oh Boy!

Fantastic Package of Superior Sound and Durabality
I am an older DJ and would commonly lean towards a wooden cabinet for sound quality, but over the past few years the electronic correction (i.e. EQ) of these cabinets have transformed into making the poly surround a fantastic option for mobile DJ's. I would recommend the matching Mackie Bag or equal product. Fantastic sound and ample power for indoor or outdoor productions.

Highly recommended for their durability and quality.

It's a Mackie. like real Mackie !
I needed these for an event that included a 12 hour auction. We had a set of much older analog 12" Mackies that have been bombproof for us. After reading other reviews and some conversations with a couple other sound people I trusted I purchased 4 of these units. We flew them right at 14" off an asphalt floor with a higher insulated ceiling above. I let them break in over a couple hours a day leading up to the event. I must say I was not let down. Extremely clean and plenty of volume. The vocals during the auction were absolutely clear and crisp. The music was also exceptional that we play leading up to the auction and during breaks. Awesome speaker for somebody mobile or a smaller venue that needs volume and clarity. Easily comparable to much higher priced loudspeakers and monitors. Hats off to Mackie on this model number. Also Matt and the staff at Sweetwater guaranteed other purchases in the future. The customer service was thorough and precise, a great attention to every aspect of the purchase along with follow up contact. Fabulous job!

Mackie SRM 450v3
Great stand-alone speaker for simple PA/karaoke. 2 channel mixer is great addition from v2.
