Tried and True


This popular powered speaker makes an ideal powered monitor for keyboards as well as an obvious choice for a vocal PA system. The 12" driver and matched 1000 watt internal power make it a convenient choice for small to medium sized venues. This is a hands on review by Jim at Sam Ash Columbus

Fill the room with clear sound


It doesn't matter if you're a DJ, church, or Iron Maiden tribute band, you need loudspeakers that won't cut out in the middle of a show, or distort when you turn them up past 3. That's why Mackie designed the SRM450. The first and only portable active 2-way loudspeaker with onboard bi-amplification, active crossovers, time-correction and renowned Mackie sound quality. Thanks to countless hours of R&D, and one very-hard-to-please Greg Mackie, the SRM450 delivers real, accurate bass down to 55Hz; midrange that's free from ear-fatiguing harshness; and detailed treble out to 20kHz. Better still, the SRM450 offers astonishingly wide dispersion that lets your whole audience hear clearly, whether they're in the front, back, or way out on the sides of the room. Above all, the SRM450s crank! Without a hint of distortion, they effortlessly achieve sound pressure levels beyond the legions of look-alike portable loudspeakers on the market today.

I have put quite a few of these through the grinder and they hold up well. Dropped and dropped again..someone poured beer on them, you name it. Oh yeah they sound incredible as well hands on product review from Lee @ Sam Ash Cincinnati




1000 watts


At 1000 watts and simple to use set up, this speaker is the perfect choice for performers of all kinds. Public speaking, DJ, acoustic performers, etc. The ease of use cant be understated, with its feedback canceling button and speaker mode selection. Easy to use is the take away from this review. Very easy to use. This is a real hands on review by Billy @ Sam Ash
