The Lambda Series TD drivers are setting a new higher standard for performance and durability. Designed for punishing professional use, they also have the clean sound needed for critical monitoring and audiophile uses. The TD12M is a high sensitivity, high power handling, wide bandwidth driver of which there is no comparison.

These drivers are capable of reproducing frequencies of up to 2Khz off axis, and much higher with a more narrow dispersion pattern. They are rated for 500W continuous power handling. Power compression is perhaps the lowest of ANY woofer currently available due to the combination of shorting rings and the phase plug. As a result, inductance and distortion is also extremely low.

The Apollo option adds two additional massive aluminum shorting rings. This further linearizes inductance and greatly adds to the heatsinking ability of the driver for high power usage.
