Deaf Bonce AT-32 Review: A 108 dB Super Tweeter for Loud Apocalypse Front Stages
Updated: Oct 6
The Deaf Bonce AT-32 is a pair of Apocalypse super tweeters with aluminium diaphragms and neodymium motors, rated at 35 W RMS (70 W max) with an SPL figure of 108 dB and a response of 4 kHz to 20 kHz. At ₹13,990 MRP, it has the highest listed output of the five Deaf Bonce super tweeters we stock, and it is priced between the Hannibal TH-25G and the Apocalypse AP-T25 NEO V2. Its high listed output makes it a candidate for loud front stages where very efficient Apocalypse midranges need a tweeter that can keep up. Specifications and today's offer are on our AT-32 product page.
Quick summary
108 dB is the highest SPL figure among the Deaf Bonce super tweeters we stock, about 6 dB above the very efficient Apocalypse midranges on paper, so it gives the most output per watt but still needs its level set.
Our listing describes a horn shaped for wide dispersion, with a 53 mm cut-out and 34.5 mm mounting depth.
Our listing gives Deaf Bonce's recommended high-pass of 8 kHz at 12 dB per octave.
Deaf Bonce's US product page was incomplete when we checked, so every figure here comes from our listing.

All figures come from our store listing. Deaf Bonce's official AT-32 page confirmed only the model, series and pair packaging when we checked in October 2026; its response, power and impedance fields showed placeholder values, but the manual linked from that page can be read. Its specification table has no extractable labels, yet its values match our listing's power, SPL, impedance and response figures, and it gives the same 8 kHz, 12 dB per octave high-pass and the same 53 mm and 34.5 mm dimensions. Voice coil size, body material and box contents are not in our listing.
Why 108 dB matters: matching Apocalypse midranges
A super tweeter has to keep pace with the midrange below it, and some Apocalypse midranges are unusually efficient. Our listings put the AP-M61AC at 101.6 dB and the AP-M67AC at 101.7 dB, while the neodymium AP-M65AN lists 102.5 dB. Against those, the AT-32 sits about 6 dB higher on paper, a smaller gap than a 105 or 106 dB tweeter has to a less efficient Machete or Hannibal midrange. The 105 and 106 dB tweeters would sit closer still to these Apocalypse midranges, so the AT-32's case is more output from the same 35 W rating, not a tighter level match.
A 6 dB gap means the tweeter needs roughly a quarter of the midrange's amplifier power for an equal level, which would still be 75 W beside a 300 W midrange such as the AP-M67AC. The 35 W rating is workable mainly because above 8 kHz music carries little energy. In practice the tweeter channel will run at a low gain, and the real dangers are clipping and a crossover set too low, not a shortage of watts.
Filters, wiring and the horn
For a loud Apocalypse build, give the tweeters their own amplifier channels rather than sharing a high-power midrange channel through a capacitor. A small four-channel amplifier such as Deaf Bonce's MFA-4.80, listed at 80 W x 4 into 4 Ω with a high-pass adjustable up to 12 kHz at 12 dB per octave, can apply the recommended 8 kHz filter directly, with its gains set low. Our MFT-25 review covers the passive alternative; remember that a single capacitor gives only 6 dB per octave, half the recommended slope.
Our listing describes the AT-32's horn as shaped for wide dispersion. Horn loading is one of the ways tweeters reach very high sensitivity, and it makes aim and surroundings matter: keep the mouth clear of trim edges, mount both tweeters symmetrically and start with them pointed towards the opposite seat. If the top end sounds hard, angling them slightly away from the listener can help as much as turning the gain down.
What owners and reviewers say about the Deaf Bonce AT-32
When we checked in October 2026, we found no owner or reviewer opinions on the AT-32. The retailers, catalogues and forums we tried were blocked to us or didn't list it, and with the official page incomplete, there isn't even a manufacturer description to quote. Everything above is based on our listing's figures and general installation practice.
If you run a pair alongside Apocalypse midranges, we would like to hear how you set the filter and level.
AT-32 vs MFT-25, TH-25G and AP-T25 NEO V2
The Machete MFT-25 (₹8,990) lists 106 dB and fits a smaller 41.5 mm hole, and the Hannibal TH-25G (₹10,990) lists 105 dB with a titanium dome and a 57.3 mm hole. Both sit closer in level to Machete and Hannibal midranges than the AT-32 does, and, on paper, closer to the Apocalypse midranges too. The AP-T25 NEO V2 (₹21,990) raises the rating to 50 W but publishes no SPL figure and needs 53.0 mm of depth, so if output per watt is the priority, the AT-32 is the one with the numbers to back it.
Who should buy it, and who shouldn't
Buy the AT-32 if you are pairing efficient Apocalypse midranges such as the AP-M61AC, AP-M67AC or AN models, you have spare amplifier channels for the tweeters, and you can mount a 53 mm horn tweeter where it has a clear path to the listener.
Skip it if your midranges are Machete or Hannibal models listed in the 90s, where its extra output just means more attenuation, or if you need the tweeter to hide in a small factory opening; the MFT-25 is easier there.
Installation notes for Indian cars
A 53 mm hole and 34.5 mm of depth suit a moulded A-pillar, a dashboard pod or a custom sail panel. Measure any factory location before assuming it fits, and check for curtain airbags before cutting into A-pillar trim. Use mechanical fixings rather than tape, because summer heat on the dashboard softens adhesives.
Route the tweeter cables separately from the high-current amplifier wiring, keep any passive parts accessible, and check polarity by ear once everything is connected. VA3 Car Studio in Ghaziabad can build the pods, set the crossover and match levels with your midranges.
Price and where to buy
The Deaf Bonce AT-32 has an MRP of ₹13,990 for the pair. VA3 Car Studio often sells below MRP, so check the current offer on the AT-32 listing. Deaf Bonce's speaker catalogue also lists separate AT-32 Sport and AT-37 Sport models, so make sure the box says AT-32. Every pair we sell is genuine.
The bottom line
The AT-32 earns its place through one figure: 108 dB, the highest listed among the Deaf Bonce super tweeters we stock, which gives it the most output per watt to set against the efficient Apocalypse midranges. High-pass it at the recommended 8 kHz on its own amplifier channels, aim the horn carefully, and its 35 W rating is usually enough.
Deaf Bonce AT-32 FAQ
Which midranges suit the Deaf Bonce AT-32?
Efficient Apocalypse midranges such as the AP-M61AC and AP-M67AC, listed at 101.6 and 101.7 dB, and the neodymium AN models. The AT-32's 108 dB figure sits about 6 dB above them on paper, a closer match than with Machete or Hannibal midranges.
What crossover does the AT-32 need?
Our listing gives Deaf Bonce's recommended high-pass of 8 kHz at 12 dB per octave. An amplifier with a high-pass that reaches 8 kHz, a DSP or a second-order passive network can provide it; a single capacitor gives only 6 dB per octave.
Is 35 W enough for the AT-32 in a loud system?
Usually, yes. With a 108 dB SPL figure and an 8 kHz high-pass, the tweeter needs only a fraction of the midrange's power for an equal level, and music carries little energy that high. Clipping and over-low crossovers are the real risks.
