What's the difference between FP20000Q and FP22000Q?

What's the difference between FP20000Q and FP22000Q?

Why we make the FP20000Q power amplifier?
From 2016, many clients asked for high power amplifier, which can work for 4 units dual 18 inch subwoofers. So we develop model FP20000Q amplifier.

2250 W x 4 ch @ 8 ohms
4000 W x 4 ch @ 4 ohms

It is equal to double FP14000 amplifiers, which is suit for 4 units dual 18 inch subwoofers.

Until now, FP20000Q is the most popular model in all Sinbosen FP series power amplifiers.
Why we make the FP22000Q power amplifier?
User's requirement is incessant. Some clients asked for superpower amplifier to run their more big subwoofer, such as dual 21 inch subwoofer. FP20000Q already can not meet their needs.

Sinbosen also do it. We spend long time to develop the NEW AMPLIFIER FP22000Q. This is unparalleled power amplifier, which research and development by Sinbosen Audio.

2500 W x 4 ch @ 8 ohms
4650 W x 4 ch @ 4 ohms

More powerful than Model FP20000Q. Suitable for dual 21 inch subwoofer, not just dual 18 inch subwoofer.

We ensure FP22000Q will Rock your stage with great powerful sound!
