In spite of its small stature, the U SUB delivers a very deep, powerful yet clean, and dry sound. The speaker cabinet is a hybrid- vented plus front-loaded, 2x 18”- Chassis and has performance of the highest quality.

What makes the U SUB unique is the heavy-duty long excursion speaker with a 100 mm voice coil and reinforced cone, plus a directivity for frequencies in the range of 40Hz.  The U SUB´s small size makes it especially qualified for venues where little space before the stage is available, specifically in combination with a T LINE, or U LINE where the subs need to be flown. Integrated U-flyware allows secure stacking and rigging with several KS AUDIO CPD speaker systems. Three U SUB stacked upon one another provide the correct height level for the CPD 1214 or CPD 12. At the same time, a 2/1 cardioid can be realized (optional), with the U flyware also securely connecting the backward facing U SUB.

Recommended Amplifiers are TA 2D and TA 4D with F MOD. The input matrix of the U SUB allows operation as Mono subwoofer. The Low bass of both Channels are added together
and send to the amps via controller. The stereo signal (for example analog out to xlr m outputs) is still available as for the tops.

The speaker cabinet construction is, like any KS AUDIO system, built from birch plywood with an extremely robust charcoal colored Polyurethane coating. Optionally, finish can be changed to any desired color from the RAL color charts. U- flyware, handles and protective grill, with or without acoustic foam, and four heavy-duty wheels on the backside, are further features of this premium product. A protective transport cover is also available.

The sturdy protective grill covers the entire front and can also be covered in “invisible” acoustic foam. A protective transport cover is also available.
