Deaf Bonce TH-25G Review: A Titanium Super Tweeter for Hannibal Systems
Updated: Oct 6
The Deaf Bonce TH-25G is a pair of Hannibal super tweeters with titanium diaphragms, neodymium magnets and aluminium bodies, rated at 35 W RMS (70 W max) with an SPL figure of 105 dB and a response of 3 kHz to 20 kHz. At ₹10,990 MRP, it sits in the middle of the five Deaf Bonce super tweeters we stock, above the Machete MFT-25 and below the Apocalypse AT-32. It is the natural top end for a Hannibal midrange system, and its metal construction suits installers who prefer an aluminium body to a plastic one. Prices are on our TH-25G product page.
Key takeaways
A titanium-diaphragm super tweeter in an aluminium body, listed from 3 kHz, the lowest starting point of the five Deaf Bonce super tweeters we stock.
Our listing gives Deaf Bonce's recommended high-pass of about 8 kHz at 12 dB per octave, which meets the 8–10 kHz low-pass listed for the Hannibal HM-6E and HM-6S.
At 105 dB it is much more efficient than Hannibal midranges, so expect to reduce its level.
It needs a 57.3 mm hole and 37.0 mm of depth, and its housing is listed at 74.5 mm across.

Power, response, SPL, materials, depth, cut-out and weight match Deaf Bonce's official TH-25G page, checked in October 2026. The housing size, the aluminium voice-coil wire and the recommended filter come from our listing, and the manual linked from the official page gives the same housing size, wire and an 8 kHz, 12 dB per octave high-pass; the page itself doesn't give them.
Titanium, aluminium and a 3 kHz lower limit
Titanium is light and very stiff, which is why it turns up in tweeter domes built for high output. Like other metal domes it tends to sound bright and forward, so placement and aiming shape the result: firing across the car rather than straight at your ears takes the edge off. The aluminium body is the other practical difference from the plastic Machete tweeters. It gives the tweeter a solid mounting flange, though the packed weight of 0.71 kg against 0.26 kg for the MFT-25 means it deserves screws or a proper pod rather than double-sided tape.
The 3 kHz lower limit matters less than it first appears. Deaf Bonce's recommendation, as our listing quotes it, is still a high-pass of about 8 kHz, and that is where to start. What the lower limit gives you is margin: crossed at 8 kHz, the TH-25G is working well inside its listed range rather than near the edge of it. That is margin on paper, not a promise of cleaner output at high volume.
Matching it to Hannibal midranges
The filter recommendations line up neatly. Our listings for the Hannibal HM-6E and HM-6S suggest a low-pass of 8–10 kHz at 12 dB per octave, and the TH-25G takes over from about 8 kHz at the same slope. On an amplifier, give the tweeters their own pair of channels with a high-pass that reaches 8 kHz; our MFT-25 review lists which Deaf Bonce amplifiers can do that. On a passive setup, a capacitor alone gives only 6 dB per octave; textbook first-order maths puts about 5 µF near 8 kHz on a nominal 4 Ω load, and halving the capacitance roughly doubles the crossover frequency.
Level is the other half of the job. The Hannibal midranges are listed between 90.9 dB (HM-6E) and 93.7 dB (HM-60 PRO), all as SPL figures, so the 105 dB TH-25G sits more than 11 dB higher on paper. Set the tweeter channel gain low, or fit an L-pad on a shared channel. The 35 W rating is ample for the top octave; clipping and an over-low crossover are the real risks.
What owners and reviewers say about the Deaf Bonce TH-25G
When we checked in October 2026, we found no owner or reviewer opinions on the TH-25G. The retailers, catalogues and forums we tried were blocked to us or didn't list it, and Deaf Bonce's own page carries specifications but no descriptive text, so there is nothing independent to report about its sound.
If you run a pair with Hannibal midranges, we would like to hear where you set the crossover and how the titanium domes sound in your car.
TH-25G vs MFT-25, AT-32 and AP-T25 NEO V2
The Machete MFT-25 (₹8,990) is cheaper, 1 dB higher on paper at 106 dB and far easier to hide in a 41.5 mm hole, but it uses an aluminium dome, a plastic body and a response listed from 4 kHz. The Apocalypse AT-32 (₹13,990) has the highest listed SPL of these, 108 dB, with a 53 mm cut-out. The AP-T25 NEO V2 (₹21,990) raises the rating to 50 W but needs a 62.4 mm hole and 53.0 mm of depth.
Who should buy it, and who shouldn't
Buy the TH-25G if you are building around Hannibal midranges, you want a metal-bodied super tweeter for a dashboard or pod, and you can high-pass it at the recommended 8 kHz.
Skip it if you need to hide the tweeter in a small factory location, where the MFT-25's 41.5 mm hole is far easier. If you are pairing very efficient Apocalypse midranges such as the AP-M61AC, listed at 101.6 dB, the TH-25G's 105 dB sits 3.4 dB above it on paper, closer than the AT-32's 108 dB.
Installation notes for Indian cars
Measure any factory tweeter location before assuming it can take a 57.3 mm hole and 37.0 mm of depth; it often needs a surface pod, a moulded A-pillar or a dashboard panel cut to suit. Our article on aluminium pods shows the sort of mount that suits a metal-bodied tweeter. Check for airbag routes inside the A-pillar before cutting anything.
Deaf Bonce's manual gives an operating range of +5 to +40 °C for the TH-25G, so the aluminium body is not a reason to leave it in the hottest spots; direct summer sun also bakes adhesives and cable insulation, so use mechanical fixings and route wiring away from the hottest surfaces. Mount the tweeters symmetrically and aim them towards the opposite seat, then fine-tune the level by ear. VA3 Car Studio in Ghaziabad can fabricate the mounts and set up the crossover.
Price and where to buy
The Deaf Bonce TH-25G has an MRP of ₹10,990 for the pair. VA3 Car Studio often sells below MRP, so check the current offer on the TH-25G listing. The listed box contents are two tweeters, a manual and a warranty card, so budget for a crossover or capacitors. Every pair we sell is genuine.
The bottom line
The TH-25G is an efficient, metal-bodied super tweeter that suits Hannibal systems: titanium domes, aluminium bodies, a response listed from 3 kHz and a recommended crossover that meets the low-pass listed for the HM-6E and HM-6S. Give it its own filtered channel or a proper network, bring its level down, and allow for its larger mounting footprint.
Deaf Bonce TH-25G FAQ
Can I cross the Deaf Bonce TH-25G lower than 8 kHz?
Its response is listed from 3 kHz, but our listing gives Deaf Bonce's recommended high-pass of about 8 kHz at 12 dB per octave. Start there; crossing lower increases the load on the dome, so only experiment with a steep filter and modest levels.
Which midranges suit the TH-25G?
Hannibal midranges such as the HM-6E and HM-6S are listed with an 8 to 10 kHz low-pass, which meets the TH-25G's recommended 8 kHz high-pass. Expect to lower the tweeter's level, since it is more efficient on paper.
What hole size does the TH-25G need?
The cut-out is listed at 57.3 mm with 37.0 mm of mounting depth, and the housing is 74.5 mm across, so it often needs a pod, a moulded A-pillar or a custom dashboard panel.
