Deaf Bonce AP-M81SE Review: 8-Inch Apocalypse Midrange With 170 W Headroom
Updated: Oct 6
The Deaf Bonce AP-M81SE is a pair of 8-inch Apocalypse midrange drivers rated at 170 W RMS (340 W max) into 4 Ω, with 95.1 dB SPL, a 110 Hz–10 kHz response, paper cones, ferrite magnets and 1.5-inch CCAW voice coils. It's one of two 8-inch Apocalypse mids we sell, alongside the AP-M81AC, and Deaf Bonce marks it as a new model. Its MRP on our store is ₹18,990, well below the 8-inch AP-M81AC. It suits builds with custom baffles, pods or kick panels that can take an 8-inch driver, with a strong amplifier, super tweeters and a subwoofer. See it on our Deaf Bonce AP-M81SE product page.
The AP-M81SE in brief
An 8-inch midrange with 170 W of rated power handling and a strong motor (BL 8.15 T·m).
On paper it is less sensitive than the 6.5-inch AP-M61SE (95.1 dB against 101.5 dB), so the bigger cone buys headroom and cone area, not efficiency.
It needs a 186.0 mm cut-out and 87.5 mm of depth, so it won't drop into a 6.5-inch opening.
Deaf Bonce's manual asks for a high-pass at 150–250 Hz (24 dB/oct) or 250–350 Hz (12 dB/oct) and a low-pass at 8–12 kHz.

What the 8-inch cone does and doesn't buy
A bigger cone moves more air for the same excursion, which is why loud builds sometimes choose an 8-inch mid for upper-bass punch and output that a 6.5-inch struggles to match. The AP-M81SE backs that up with a 1.5-inch coil, a 170 W rating and a BL of 8.15 T·m, higher than the 6.15 of the 6.5-inch AP-M61SE or the 7.70 of the AP-M60SQL.
What it doesn't buy, on paper, is efficiency. Deaf Bonce quotes the 6.5-inch AP-M61SE at 101.5 dB and the AP-M81SE at 95.1 dB, so per watt the smaller driver is the louder one. The 8-inch's response also stops at 10 kHz, so of the manual's 8–12 kHz low-pass window, we'd use the lower end and let a super tweeter take over early. Treat the AP-M81SE as the choice for headroom and cone area, with an amplifier that can feed it.
Amplifier, filters and tweeters
The joint AP-M61SE and AP-M81SE manual lists thirteen Deaf Bonce amplifiers, from the AAK-180.4 to the AHL-200.4. In our store, the AAB-500.4D is the match: 200 W x 4 into 4 Ω sits just above the AP-M81SE's 170 W rating. Its 12 dB/oct high-pass runs up to 6 kHz, covering Deaf Bonce's 250–350 Hz option, but its low-pass also stops at 6 kHz, so the 8–12 kHz low-pass needs a DSP. The manual for Deaf Bonce's own processor lists no selectable filter range or slopes, so ask us before relying on the M8-DSP.
For the top end, the Apocalypse AT-32 (our listing gives 35 W RMS, 108 dB SPL and an 8 kHz high-pass) or the AP-T25 NEO V2 (50 W RMS, 4–20 kHz) complete the set. Deaf Bonce's starting point for gains is head-unit volume no higher than 80% and amplifier sensitivity at 50%; refine it with a test tone.
What owners and reviewers say about the Deaf Bonce AP-M81SE
We found no owner or reviewer feedback on the AP-M81SE when we checked in October 2026, which isn't surprising for a model Deaf Bonce still labels as new. Its product page has no reviews, a Steve Meade Designs forum search for Apocalypse mids found nothing on it, and Amazon India, Flipkart, Team-BHP, Reddit and DIYMobileAudio blocked our requests.
The only related owner report we found concerns a 6.5-inch sibling, the AP-M61AC, not this model: in a February 2025 Steve Meade Designs thread, its owner reported that a distortion detector showed no distortion until the gains were near the 12 o'clock position, a setting the owner believed would already be distorting, and forum replies pointed to filtering and signal-processing causes, including a missing high-pass, rather than to the speakers. No fix was posted. It is a set-up problem on another model, not a verdict on the AP-M81SE. If you've fitted AP-M81SEs, we'd like to hear how they perform.
AP-M81SE vs AP-M81AC and AP-M61SE
The 8-inch AP-M81AC (₹34,990) is the bigger brother: our listing rates it at 300 W RMS and 97.5 dB, with a 2-inch coil, a cast aluminium frame and 84 mm of depth. It costs ₹16,000 more, so it is worth considering mainly if you have the amplifier power to use that rating.
The 6.5-inch AP-M61SE (₹13,990) is ₹5,000 cheaper, far more sensitive on paper, and needs only a 149.5 mm cut-out and 72.5 mm of depth. Unless you specifically want 8-inch cone area and can build the mounting, it's the easier route to a loud front stage.
Who should buy it, and who shouldn't
Buy the AP-M81SE if your build already includes custom baffles, pods or kick-panel enclosures sized for 8-inch drivers, you can supply around 170–200 W per channel, and you want more cone area and headroom than a 6.5-inch offers.
Look elsewhere if you want a straightforward door swap (choose a 6.5-inch Apocalypse such as the AP-M61SE), you're chasing the most SPL per watt, or you hoped to avoid an amplifier and DSP.
Installation notes for Indian cars
An 8-inch driver with a 186.0 mm cut-out won't fit an opening made for a 6.5-inch speaker, and it needs 87.5 mm of depth behind the mounting surface, so plan on a custom baffle, a door pod or a kick-panel mount. We can't promise fitment for any car without measuring, so ask us to check yours.
The pair weighs 6.27 kg packed, so mount each driver on a rigid, well-fixed baffle that won't flex on rough roads, and seal and damp the door or pod; for the damping materials and order of work, see our damping guide. The manual's operating range is +5 °C to +40 °C, so let a hot cabin cool before playing loud. VA3 Car Studio in Ghaziabad offers professional installation, can make door baffles or speaker pods and can tune a DSP.
Price and where to buy
The Deaf Bonce AP-M81SE carries an MRP of ₹18,990 for the pair on our store listing. VA3 Car Studio often sells below MRP, so check the current offer on the AP-M81SE product page. Every pair we sell is a genuine Deaf Bonce product.
The bottom line
The AP-M81SE is a specialist's mid: an 8-inch Apocalypse driver with a strong motor and a 170 W rating, for builds with mounting made to suit it. It isn't the efficiency choice, since the 6.5-inch AP-M61SE is quoted 6.4 dB higher, and it needs a DSP to follow Deaf Bonce's low-pass advice with the AAB-500.4D. If you have the space and the power, it offers more cone and headroom for much less than the AP-M81AC.
Deaf Bonce AP-M81SE FAQ
Will the Deaf Bonce AP-M81SE fit a 6.5-inch door opening?
No. It needs a 186.0 mm cut-out, much larger than the 149.5 mm the 6.5-inch AP-M61SE needs, plus 87.5 mm of depth. Plan on a custom baffle, pod or kick-panel mount.
Is the AP-M81SE louder than the 6.5-inch AP-M61SE?
Not per watt. Deaf Bonce quotes the AP-M81SE at 95.1 dB and the AP-M61SE at 101.5 dB. The 8-inch takes more power (170 W against 130 W RMS) and has more cone area, but the 6.5-inch is the more efficient driver on paper.
What amplifier suits the AP-M81SE?
Something around 170–200 W per channel into 4 Ω. The AAB-500.4D from Deaf Bonce's recommended list makes 200 W x 4 at 4 Ω, but its low-pass stops at 6 kHz, so add a DSP for the 8–12 kHz low-pass.
