Spec Sheet PDF

SEAS Extreme subwoofers are designed and manufactured to perfection to enhance the low frequency experience in any sound system. The drivers can be used for many applications including sealed box, passive radiator tuning, transmission line, or even open baffle. This driver works best as a standalone sub or in 3-way systems. The extremely stiff aluminium cone provides tremendous bass precision.

We are so proud to finally present and launch our new Extreme 8-inch driver L22ROY2!

This driver has been in development for years and is based on our design philosophy with extreme excursion and low noise as its big brother L26ROY. Perfect for use in applications where space is limited, but the need for extreme, detailed, and precise bass is high.

The name of the driver L22ROY2, indicates that we, after an internal revision, decided to move the advanced magnet system another step forward by optimizing it with an additional aluminum ring above the pole piece to reduce distortion even further with a symmetric and linear inductance for large excursions.

We are very happy with the results. The excursion possibilities and power handling in this driver can be pushed to the extreme.

A 2” diameter high power titanium voice coil former with a long copper winding for excellent force transfer and transient sound reproduction. A large rubber surround together with a textile spider allow for the outstanding linear excursion of the coil while keeping it well centered at high power. These characteristics result in a very low mechanical damping for better clarity bringing up the micro details in music.

A large FEA optimised magnet system with a very big center hole through the pole piece and precisely fitted copper parts for excellent linearity, high power handling and low distortion. Below the T-shaped pole piece there is a heavy copper ring and on top, a thick aluminium ring, they both help to reduce nonlinear and modulation distortion. The stiff and stable injection moulded metal basket keeps the critical components in perfect alignment. Large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance.

Sample Box Alignments:

• Single woofer 0.4 to 0.75 cf sealed: F3 49 Hz, F6 36Hz, F10 26Hz
• Dual woofers in parallel 0.8 to 1.5cf sealed: F3 49 Hz, F6 36Hz, F10 26Hz
• Single woofer in 1.5 cf w/ 2.5" x 11" long port for a F3 of 24Hz
• Dual woofers in 3.0 cf w/ 3" x 7.5" long port for a F3 of 22Hz

The SEAS R&D favorite application for this driver is to use two parallel connected drivers in a closed box, mounted on opposite sides to reduce cabinet resonances. The low end should then be tuned to fit the room and your personal preference.

The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees angle using a 22L closed box. Input 2.83 Vrms, microphone distance 0.5m, normalized to SPL 1m.The dotted line is a calculated response in infinite baffle based on the parameters given for this specific driver. The impedance is measured in free air without baffle using a 2V sine signal.
