ADAM Audio Sub20 - Single – No Longer Available

400 watt subwoofer with 2 x 10" drivers
MFR# Sub20

Product Description

The ADAM Sub20 is a very powerful subwoofer designed for medium sized or larger control rooms in which powerful and yet accurate extra deep bass monitoring is required.

The Sub20 is equipped with two long throw 10” drivers which are meant to reproduce LFE or other low frequency signals down to 25Hz.  

The power of two subwoofers

The Sub20 has two drivers, which are mounted in chambers at opposite sides of the cabinet.  Due to this alignment, the forces applied to the cabinet oppose each other and consequently compensate themselves, so that the cabinet stays much quieter than with conventional arrays.  Distortion is drastically reduced in this manner, resulting in improved signal clarity, especially at higher levels.

There are two down firing bass reflex tubes that, because of their size and construction, successfully avoid ventilation noise.

PWM amplifers

The amplifier section has two units, each capable of delivering 200W continuous or 300W peak power to their corresponding drive units.  Both power supply and amplifier section use PWM technology, meaning very high efficiency (≥90%) and cool operation in even the most critical phases of operation.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
