Installed at Mediocre Customs, Cary IL. We fit them at our Cary shop with the right adapters or custom pods, then wire and tune them so the front stage sounds right from the driver's seat.
The ESB 9.4M is the larger, higher-output midrange of ESB's 9000 (Novemila) series, winner of the EISA In-Car High-End Component award for 2024–2025. Twin coupled neodymium magnets, a copper ring in the gap to cut inductance, and a 4-inch carbon-fiber cone reach down to 100 Hz for a fuller, more dynamic midrange.
Highlights
- 4-inch high-modulus carbon-fiber cone with NBL rubber surround
- Twin coupled high-temperature neodymium magnets
- Pure copper ring in the gap to reduce inductance
- Laminated aluminum dust cap and CNC clamp ring
- Die-cast aluminum alloy basket
- 120 W nominal / 240 W transient
- 100 Hz – 20 kHz, 90.6 dB sensitivity
- Optional CNC-machined grille
- Made in Italy
Best for
3-way 9000 Series systems where the midrange has more room to work, in kick panels or door pods. Pair it with the 9.1T-28 or 9.1T-25 tweeter and the 9.6W mid-woofer.

Questions we get in the shop
Can I buy it online and have you install it?
Yes. Order here, pick in-store pickup, and we hold it for your install day. You can also buy it at the counter.
Will they fit my factory locations?
Most vehicles take these with an adapter. Bring it in and we'll check depth and tweeter spots.
Do I need an amp?
They'll run off a radio, but they sound their best with clean amp power. We'll set you up either way.
