If you're using it to reinforce Mackie SRM loudspeakers, you'll find presets to match the SRM1850 to the specific speakers you're using (no tweaking required). With other speakers, the variable crossover makes it easy to fit the SRM1850 into the mix. And because it has dual full-range outputs in addition to dual highpassed outputs, you can integrate the SRM1850 into virtually any PA system.

Smart DSP enhances your sound and saves you time

The Mackie SRM1850 powered subwoofer is smart. It has built-in Smart Protect DSP to protect the amp/drivers from signal clipping and crossover presets for use with Mackie's SRM series speakers.

The SRM1850's rugged all-wood, internally braced cabinet uses a tough 18-gauge steel grille to protect its speaker from damage.

Tight clean bass!

This sub is really light weight for its size. I do wish this sub can be a bit smaller to fit in my truck doors perfectly. I brought a pair of mackie srm 550 and it really surpassed my expectation and this sub was no different. I do however think the built quality such as the coating can look and feel much better, but for the price, I can't complain too much about it. I brought a pair of these. Shipment was fast and I was happy to see them. One of the subs did show some white smudge marks on the grill but I tested them out and they worked flawlessly. Match these subs with my srm 550 and they sound amazing. You can also use these with other tops and fine tune these subs to your own liking. Don't forget the covers for these!! Thank you again sweet water for the A+ service. I would def. recommend these subs

Great SUB!!!!

Lightweight but powerfull!!! great sound.

Do you like thunder?

These things are monstrous (sound-wise). They are super clean and tight and have massive power. Using these with a set of QSCKW12s and dowser! It is a really clean sound! I can't say that I have A/B'd these side by side with others, but I did "test drive" others in-store and at Gearfest 2015. These stood out to me as the best bang for my buck. I bought these following Gearfest2015 and using only a mixer I am getting super clean powerful sound already. Next on the list is an EQ to really get the mix dialed in.
