Comparable 5.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Visaton MR130-8 5" Midrange Driver 8 Ohm does not fit your target box volume or tuning. Each entry links to its full enclosure design and Thiele/Small parameters.
⚠️ Engineering Notice for Builders
- Limited linear excursion (Xmax: 2.0 mm); set a high-pass subsonic filter at 25–30 Hz when driven with high power.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Visaton MR130-8 5" Midrange Driver 8 Ohm?
A simple ported box is not recommended for Visaton MR130-8 5" Midrange Driver 8 Ohm: the textbook alignment (1.5 liters tuned to 425.0 Hz) needs a 4.6 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 MR130-8 5" Midrange Driver 8 Ohm be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 0.085 liters with a Qtc of 4.936 (above Butterworth: Qtc cannot fall below Qts (3.49)), the system exhibits an F3 of 719.9 Hz.
What port dimensions should be used for Visaton MR130-8 5" Midrange Driver 8 Ohm to avoid port chuffing?
A straight 12.5 cm port would need 4.6 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
