Deaf Bonce AP-M67AN Review: Is Neodymium Worth ₹50,000 More Than the AP-M67AC?
Updated: Oct 6
The Deaf Bonce AP-M67AN is a pair of 6.5-inch neodymium Apocalypse midranges rated at 300 W RMS (600 W max) into 4 Ω, with an SPL figure of 102.0 dB, a 1.75-inch CCAW voice coil and a response of 200 Hz to 14 kHz. At ₹79,990 MRP, it is the most expensive Apocalypse midrange we stock, ₹50,000 above the ferrite AP-M67AC that shares its 300 W rating. That gap is the real question for most buyers, so this review sets the published figures side by side and explains who gains from the neodymium version. You can check today's offer on our AP-M67AN listing.
Key points
A 6.5-inch neodymium midrange with a paper cone, cloth surround, aluminium frame and 1.75-inch CCAW coil, rated at 300 W RMS.
Deaf Bonce publishes Fs 125 Hz, Qts 0.31, Vas 5.72 L, a 152 mm cut-out and a 67.5 mm depth, and our listing matches.
On paper it is not meaningfully louder than the AP-M67AC and has the same rating; the differences are depth, documentation and magnet material.
Deaf Bonce's manual recommends a high-pass at 150–250 Hz (24 dB per octave) or 250–350 Hz (12 dB per octave), so plan for a tweeter and a subwoofer too.

These figures match Deaf Bonce's official AP-M67AN page, checked in October 2026; the page gives BL without a unit and our listing quotes T·m. Deaf Bonce doesn't publish Qes, Qms or Xmax; its filter recommendations are in the manual linked from the page, which also covers the AP-M65AN.
Neodymium versus ferrite: what actually changes
Neodymium produces a strong magnetic field from a much smaller, lighter magnet than ferrite, which is why neodymium motors tend to be shallower. That shows here: Deaf Bonce lists 67.5 mm of mounting depth against 77 mm for the ferrite AP-M67AC on our listing. Close to a centimetre can decide whether a midrange clears the window glass or fits a slim podium, though a spacer ring can often make up the difference.
What doesn't change on paper is just as telling. Both carry 300 W RMS and a 1.75-inch coil, and the AN's 102.0 dB SPL sits beside the AC's 101.7 dB sensitivity, a gap too small to hear and measured under labels that may not match. The AN is listed from 200 Hz against 100 Hz for the AC, yet our AC listing and Deaf Bonce's AN manual give the same high-pass recommendation, so the listed range alone doesn't show that either plays deeper in a car. The other tangible gain is documentation: a published cut-out and Thiele-Small figures let an installer design an enclosure with confidence, where the AC's listing offers neither.
Power: 300 W, and why more amplifier isn't better
With 102.0 dB of output on paper, the AP-M67AN plays very loud long before it nears 300 W; the rating is there for sustained, hard use. Deaf Bonce's MFA-4.320, listed at 320 W x 4 into 4 Ω at 14.4 V, matches it closely and can high-pass and low-pass at once between 50 Hz and 12 kHz at 12 dB per octave. Bigger is not safer: the two-channel ASA-1500.2 is listed at 550 W x 2 into 4 Ω, comfortably beyond the midrange's rating, so with an amplifier like that careful gain setting becomes essential.
Deaf Bonce's manual for the AP-M65AN and AP-M67AN recommends a high-pass of 150–250 Hz at 24 dB per octave or 250–350 Hz at 12 dB per octave, and a low-pass of 8–12.5 kHz at 12 dB per octave; with the 12 dB amplifiers above, the 24 dB option calls for a DSP, as our guide to DSP setup explains. With the response listed to 14 kHz, a tweeter is essential. Our listing for the AT-32 super tweeter, for example, gives Deaf Bonce's recommended 8 kHz high-pass, so low-pass the midrange to meet it.
What owners and reviewers say about the Deaf Bonce AP-M67AN
When we checked in October 2026, we found no owner or reviewer opinions on the AP-M67AN. The retailers, catalogues and forums we tried were blocked to us or didn't list it, so there is no independent verdict on how it sounds or how it holds up.
That matters more at this price than at most. We would rather tell you plainly that the case for the AP-M67AN rests on its published figures than invent a consensus. If you own a pair, your experience would be genuinely useful to the next buyer.
AP-M67AN vs AP-M67AC and AP-M65AN
Specification | AP-M67AN | AP-M67AC | AP-M65AN |
|---|---|---|---|
India MRP (pair) | ₹79,990 | ₹29,990 | ₹49,990 |
Magnet | Neodymium | Ferrite | Neodymium |
Power (RMS) | 300 W | 300 W | 200 W |
Voice coil | 1.75 in | 1.75 in | 1.5 in |
Listed output | 102.0 dB (SPL) | 101.7 dB (sensitivity) | 102.5 dB (SPL) |
Frequency response | 200 Hz – 14 kHz | 100 Hz – 15 kHz | 200 Hz – 17 kHz |
Mounting depth | 67.5 mm | 77 mm | 67.5 mm |
Cut-out | 152.0 mm | Not listed | 152.0 mm |
Against the AP-M67AC, the extra ₹50,000 buys a shallower motor, published parameters and neodymium, not more rating or meaningfully more output. Against the AP-M65AN, the extra ₹30,000 buys 100 W more rating and a larger coil, while the AP-M65AN lists a slightly higher output figure and a higher upper limit.
Who should buy it, and who shouldn't
Buy the AP-M67AN if you want 300 W of thermal headroom in the shallowest 6.5-inch Apocalypse package we stock with that rating, your install depends on published parameters and a known cut-out, and the budget is set by the build rather than the price tag.
Skip it if value matters: the AP-M67AC offers the same rating and similar listed output for far less, provided its depth fits and you can measure your own cut-out. If you don't need 300 W, the AP-M65AN gives the same depth and cut-out for ₹30,000 less.
Installation notes for Indian cars
The published 152 mm cut-out and 67.5 mm depth let you check fitment before buying, which is worth doing at this price; factory openings usually still need an adapter ring, and the window glass must clear the magnet. Seal and damp the door or build a sealed podium, following our sound damping guide, so panel buzz doesn't spoil a midrange this capable.
Heat deserves respect. Neodymium is more sensitive to high temperatures than ferrite, Deaf Bonce publishes no magnet grade, its manual gives an operating range of +5 to +40 °C, and a 300 W coil can make a lot of heat in long sessions. Avoid unventilated mounts that bake under the windscreen in summer, and leave air around the motor. VA3 Car Studio in Ghaziabad can build and install the complete front stage.
Price and where to buy
The Deaf Bonce AP-M67AN has an MRP of ₹79,990 for the pair. VA3 Car Studio often sells below MRP, so check the current offer on the AP-M67AN product page. Deaf Bonce's speaker catalogue also lists a separate M67AN Pro, so make sure the box says AP-M67AN. Every pair we sell is genuine Deaf Bonce stock.
The bottom line
The AP-M67AN is the premium way to get 300 W from a 6.5-inch Apocalypse midrange: neodymium, a 67.5 mm depth, a published cut-out and parameters, and a 102.0 dB SPL figure. It is not meaningfully louder or more powerful on paper than the AP-M67AC, so buy it for depth, documentation and the neodymium motor, and pair it with a tweeter, a sensible amplifier and careful gain setting.
Deaf Bonce AP-M67AN FAQ
Is the Deaf Bonce AP-M67AN louder than the AP-M67AC?
Not meaningfully on paper. The AP-M67AN lists 102.0 dB SPL and the AP-M67AC 101.7 dB sensitivity, and both are rated at 300 W RMS. The AN's advantages are its 67.5 mm depth, published cut-out and parameters, and neodymium motor.
What amplifier suits the AP-M67AN?
One delivering close to 300 W per channel into 4 Ω, such as an amplifier listed at 320 W x 4, gives full headroom. Larger amplifiers work only with carefully set gains, because the rating is a ceiling.
Where should I cross over the AP-M67AN?
Deaf Bonce's manual recommends a high-pass of 150 to 250 Hz at 24 dB per octave, or 250 to 350 Hz at 12 dB per octave, and a low-pass of 8 to 12.5 kHz at 12 dB per octave. Pick the low-pass to meet your tweeter, since the response is listed only to 14 kHz.
