Deaf Bonce AP-M60SQL Review: The Shallow 150 W Apocalypse Midrange
Updated: Oct 6
The Deaf Bonce AP-M60SQL is a pair of 6.5-inch Apocalypse midrange drivers built shallow: just 60.2 mm deep, with a 145.0 mm cut-out, yet rated at 150 W RMS (300 W max) into 4 Ω with 97.5 dB SPL and a 100 Hz–13 kHz response. Where the AP-M61SE and the Hannibal and Machete mids use CCAW coil wire, it has a 1.5-inch aluminium voice coil and what Deaf Bonce calls a hybrid magnet. Its MRP on our store is ₹14,990, ₹1,000 above the AP-M61SE, and it's the shallowest of the Deaf Bonce midrange pairs we sell. It suits loud front stages in doors that can't take a deep driver. See it on our Deaf Bonce AP-M60SQL product page.
At a glance
60.2 mm deep, shallower than every other Deaf Bonce mid we sell (the next, the HM-6E, is 64.5 mm), with a 145.0 mm cut-out.
150 W RMS and 97.5 dB: 20 W more rating than the AP-M61SE, but 4 dB less sensitivity on paper.
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.
Its recommended amplifiers include the AAB-500.4D, whose filters stop at 6 kHz, so plan on a DSP for the low-pass.

What the SQL build changes
Deaf Bonce doesn't explain the SQL suffix on its page. Nor does it say how this model is voiced. Next to the AP-M61SE, it gives up 4 dB of sensitivity but gains 20 W of rating, a larger 1.5-inch coil and 12.3 mm less mounting depth.
Its 0.45 Qts is lower than that of the AP-M61SE or any Hannibal or Machete mid we sell, meaning a tightly damped cone, and the 7.70 T·m BL is a strong motor for its size. The small 5.20 L Vas and 110 Hz resonance confirm it as a driver for the midrange band, with a subwoofer below and a super tweeter above. The aluminium coil wire and hybrid magnet set it apart on paper, though Deaf Bonce doesn't say how either is built.
Amplifier, filters and tweeters
The AP-M60SQL manual recommends nine Deaf Bonce amplifiers, from the AAB-600.2D to the AHL-200.4. In our store that's the AAB-500.4D: 200 W x 4 into 4 Ω, comfortably above the 150 W rating, so set the gains with care. Its 12 dB/oct high-pass reaches 6 kHz, which covers Deaf Bonce's 250–350 Hz option, but its low-pass also stops at 6 kHz, short of the recommended 8–12 kHz. A DSP can take over that job. Deaf Bonce's M8-DSP offers band-pass filtering and speaker-level inputs for a factory head unit, but its manual lists no selectable filter range or slopes, so ask us before counting on it for the 8–12 kHz low-pass.
For the top end, the Apocalypse AT-32 super tweeter is listed on our store at 35 W RMS and 108 dB SPL with a recommended 8 kHz high-pass. Deaf Bonce's gain rule of thumb is head-unit volume at or below 80% and amplifier sensitivity at 50%; a test tone gives a more reliable result.
What owners and reviewers say about the Deaf Bonce AP-M60SQL
We found no owner or reviewer feedback on the AP-M60SQL when we checked in October 2026. Deaf Bonce's product page has no reviews, we didn't find the model in the speaker list of its authorised US dealer, a Steve Meade Designs forum search for Apocalypse mids turned up nothing on it, and Amazon India, Flipkart, Team-BHP, Reddit and DIYMobileAudio blocked our requests.
The closest real-world report covers a different model, the AP-M61AC. In a February 2025 Steve Meade Designs thread, its owner reported, on a four-channel amplifier, 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, not to the speakers; the thread ended without a fix. It is a set-up problem on another model, not a verdict on the AP-M60SQL. If you run AP-M60SQLs, let us know how they've done and we'll add your experience.
AP-M60SQL vs AP-M61SE and HM-60 PRO
Against the AP-M61SE (₹13,990), the choice is depth and power handling versus efficiency: the AP-M61SE is quoted 4 dB more sensitive, but it is 72.5 mm deep against 60.2 mm and rated at 130 W. If your doors can take the depth and you want the most output per watt, the AP-M61SE is the better fit; if depth is the constraint, the SQL is the better fit.
The Hannibal HM-60 PRO (₹11,990) is the cheaper shallow-ish option at 65.0 mm, but it is rated at 130 W and 93.7 dB, so the SQL adds 20 W of rating and 3.8 dB of sensitivity for ₹3,000 more.
Who should buy it, and who shouldn't
Buy the AP-M60SQL if your doors are short on depth, you want more sensitivity than the Hannibal and Machete 6.5-inch mids give, and you'll run it from an amplifier with a DSP, a super tweeter such as the AT-32 and a subwoofer.
Look elsewhere if you have the depth and want more sensitivity for less money (the AP-M61SE), you need an even bigger power rating, or you were hoping to run it without an amplifier.
Installation notes for Indian cars
The 60.2 mm depth gives the most room of any Deaf Bonce mid we sell, but measure to the window glass with the window fully down anyway, and plan a spacer ring or baffle for the 145.0 mm cut-out. Factory openings vary by car, so ask us to check fitment for yours. Seal and damp the door so the driver's output isn't lost to panel buzz; our sound damping guide covers the damping materials and order of work.
Deaf Bonce gives an operating range of +5 °C to +40 °C, so let a sun-baked cabin cool before playing loud, and keep the paper cones clear of monsoon water inside the door. 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-M60SQL carries an MRP of ₹14,990 for the pair on our store listing. VA3 Car Studio often sells below MRP, so check the current offer on the AP-M60SQL product page. Every pair we sell is a genuine Deaf Bonce product.
The bottom line
The AP-M60SQL is the Apocalypse mid for tight doors: 150 W RMS and 97.5 dB from a 60.2 mm-deep driver with a tightly damped cone. It's less efficient on paper than the AP-M61SE, so choose it when depth decides, and give it an amplifier, a DSP for the low-pass, a sensitive tweeter and a subwoofer. With no owner reviews yet, its case rests on Deaf Bonce's published figures.
Deaf Bonce AP-M60SQL FAQ
What does SQL mean on the Deaf Bonce AP-M60SQL?
Deaf Bonce doesn't explain it on the product page, so we can't say what it signals. On paper this model trades some sensitivity, 97.5 dB against the AP-M61SE's 101.5 dB, for more power handling and a shallower build.
How deep is the AP-M60SQL?
Deaf Bonce lists a 60.2 mm mounting depth and a 145.0 mm cut-out, the shallowest of the Deaf Bonce midrange pairs we sell. Still measure your door with the window down before buying.
What amplifier suits the AP-M60SQL?
Around 150–200 W per channel into 4 Ω. The AAB-500.4D on Deaf Bonce's list makes 200 W x 4 at 4 Ω, but its filters stop at 6 kHz, so use a DSP for the recommended 8–12 kHz low-pass.
