Comparable 10.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Visaton WS 25 E 4 OHM does not fit your target box volume or tuning. Each entry links to its full enclosure design and Thiele/Small parameters.

SUITS INFINITE / OPEN BAFFLEWith Qts 1.09 a Butterworth (Qtc 0.707) box would be many times Vas. A box equal to Vas reaches Qtc 1.541; for a flat response this driver is better used on an infinite (IB) or open baffle.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Visaton WS 25 E 4 OHM?
A simple ported box is not recommended for Visaton WS 25 E 4 OHM: the textbook alignment (85.6 liters tuned to 27.2 Hz) needs a 12.3 cm port, and no nearby retune stays buildable without a bass hump. A sealed box, a passive radiator or a folded duct is the practical choice.
Can Visaton WS 25 E 4 OHM be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 107.0 liters with a Qtc of 1.541 (above Butterworth: Qtc cannot fall below Qts (1.09)), the system exhibits an F3 of 37.9 Hz.
What port dimensions should be used for Visaton WS 25 E 4 OHM to avoid port chuffing?
A straight 6.8 cm port would need 12.3 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
