SUB36

Extreme Dynamic, Low Distortion, Compact Size

The pursuit of minimum distortion is always the primary goal of Starke Sound and our SUB36 is no exception. At the same time we want the size of our subwoofer to be as compact as possible for ease of placement. Also, we want to double the energy output while keeping the lowest distortion possible. We are able to achieve these goals through the implementation of two separate technologies: Delta Force and LMF.

What is Delta Force?

Starke Sound's Delta Force design places three drivers (Tri-12) in a triangular orientation that is inherently both rigid and stable. The two active drivers are positioned back to back with a recoil angle and momentum of 180 degrees. This arrangement effectively reduces distortion caused by the movement of the diaphragms. During operation, the dual
active drivers are being pushed inward and outward. The air pressure around the drivers are offset by the opposing movement, meanwhile the passive unit moves vertically up and down. This action generates a dispersion angle of 30 degrees to the dual active drivers which maintains the stability of the internal pressure. This structure has excellent
stability providing low frequency with a substantial increase in the amount of dive. The Tri-12 unit has proven to create much more air pressure that exceeds the performance of many 18-inch medium-stroke units.

LMF low-distortion field technology

To reduce field distortion LMF technology has been included in the design of the SUB36's two active drivers. Compared to active servo technology the LMF technology has much better response. Although active servo technology can minimize the distortion, this method can never solve the time domain distortion problem. LMF solves this by imple-
menting an ideal linear magnetic field found in the driver’s coil.

Continuous energy reserves

A 800W RMS Class AB amplifier is the driving force for SUB36. It has a continuous supply of power for the working drivers while maintaining a minimal distortion level.
