There’ve been a couple of Mackie SRM650 loudspeakers here that have been waiting patiently to go out on the road. Well, before they get that opportunity, I need to know they are up the task. To ease my paranoia about new stuff going thermal the first time out, I like to leave the switches in the on positions for at least 24 hours. What the heck, as long as they are on, let’s have some music.

A little background: The SRM650 is the big dog in the revamped SRM series–or, at least it was until mackie announced the new SRM750. It features a 15” Low Frequency driver and 1.4” tweeter housed in a road-rugged all-wood cabinet. Power is rated at 1600 Watts and you get a handy two-channel mixer as part of the deal. A standout feature on the SRM series is the dummy-proof EQ button that allows you to pick one of four pre-set EQ curves, depending on the application. “PA” is basically flat for front of house use. “DJ” gives you a modified smiley face with intensified highs and lows. “MON” knocks out the lows so you can better hear your fantastic guitar licks above the other noise on stage. The last setting is “SOLO” which voices the speaker for voice. There’s also a button for eliminating feedback. We’ll see how that works when we actually get these out on the road.

It was still pretty early here in the east, so with the volume at a conservative setting (I hadn’t finished my coffee yet and my ears are still asleep) I selected the “DJ” setting and tuned in one of my favorite iRadio stations: Naxi Cafe Radio. I think it’s out of Serbia. The music mix is all over the place and I like a wild lot of musical variety, I just wish I understood what they heck the announcers are saying.


So, power on, green funkengruven Mackie logos aglow, gain set for 6AM (neighbors are still asleep) and I am taken aback at how rich and full these sound. Typically, there’s little, if any, audible low end at such low volume levels without an outboard EQ or exciter. Not so with these. Even with the gain flying low to the ground, they still sound big. For DJs who play weddings and parties (where they need to keep it down during cocktails and dinner) having a speaker that sounds strong and full at low volume is just as important as one that pumps and punches when set to stun. If the SRM650 loudspeakers sound this good at idle, I can’t wait to crank ‘em…. but not ’til my ears wake up. And we still have to talk about the subs.
