Okay, I am looking at some amps for my subwoofer. I am using four 15" Avalanche drivers in a large box system. That is another forum. It has been recommended that I use Behringers's EP2500 amplifier, which I am happy to do, but wanted to compare some others and learn something at the same time. So... specs on the Behringer are Features:
2 x 1200 watts in 2-ohm/2400 watts in 4-ohm bridged operation
2-channel, parallel or bridged mono operating modes for flexible application
Independent limiters for each channel offer dependable protection against distortion
Precise signal and clip LED indicators to monitor performance
Selectable low-frequency filters (30 Hz or 50 Hz) remove distracting infra-sound frequencies
Professional Speakon® and "touch-proof" binding post loudspeaker outputs enable secure operation
Balanced XLR and 1/4 in. TRS inputs
Connection option for extra amps in parallel operation
Ultra-reliable Toshiba®/Fairchild® high-power transistors
High-quality components and exceptionally rugged construction for long life and durability
High-current Toroid® toroidal transformer for absolute reliability and lowest noise emission
"Back-to-front" ventilation system including air filter with automatically adjusting fan speed for smooth operation
Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers
My Question is 1)what does all this really mean? Some specs I see are listed as Stereo mode, some listed like the Behringer as 2x1200. If the system simply says 600w @8ohms, but is a 2 channel amp, is that the same thing as 2x1200?
2)What does RMS X2 mean? 3)How do I compare apples to apples? 3)Why do some amps list frequency? Isn't this more a factor of the driver you are using? 4)Does "peak power" matter. One amp says 2000 w peak power but shows :
600 WATTS@2 OHMS
460 WATTS@4 OHMS
240 WATTS @8 OHMS.
How are they calculating peak power from that? 5)Is THD really a factor when using the amp for this application?
Thank for all the information. If you know of any good deals like the Behringer EP2500, please give me a website so I can check it out. I think the Behringer is around $300.00.
