B&C DE910TN – Highest-Power 1.3-Inch Neodymium Titanium Compression Driver with 110 Watt Rating
The B&C DE910TN is the most powerful compression driver in B&C’s entire product range. With 110 W AES power handling — the highest of any B&C compression driver by a substantial margin — a 2.05 T neodymium motor, 75 mm voice coil, pure titanium diaphragm, and a 0.5 kHz – 18 kHz bandwidth that reaches a full octave deeper than the composite-diaphragm DE910, the B&C DE910TN is built for applications where the HF section needs to deliver maximum sustained output under the most demanding operating conditions in professional audio.
The B&C DE910TN shares the DE910’s motor, coil, body, and mounting — but the pure titanium diaphragm and the engineering changes it enables create a meaningfully different driver. The 110 W AES rating is 37.5% higher than the DE910’s 80 W. The bandwidth extends down to 500 Hz — a frequency range where most compression drivers haven’t even begun operating. And the 16 Ω variant opens up multi-driver configurations that the 8 Ω-only DE910 can’t support.
These aren’t incremental improvements. The B&C DE910TN represents a different performance tier within the same physical platform, and the pure titanium diaphragm is the component that makes the difference possible.
Design and Construction of the B&C DE910TN
The B&C DE910TN uses a 75 mm (3-inch) aluminium voice coil driving a pure titanium diaphragm through a 1.3-inch (33 mm) exit throat. The 75 mm coil is the same unit found in the DE910 — same diameter, same material, same thermal capacity. The magnetic circuit is also shared: a neodymium magnet assembly producing 2.05 T of flux density with a shorting copper cap, generating the highest flux of any driver in B&C’s entire product catalogue.
The pure titanium diaphragm is the defining engineering difference from the DE910’s composite polyester/titanium. Where the composite uses a polyester damping layer bonded to the titanium to reduce the resonant peak, the B&C DE910TN uses titanium alone — a single-material dome without damping assistance.
Pure titanium is the stiffest and lightest diaphragm material per unit area available for compression driver use. It maintains pistonic dome behaviour at higher frequencies than any polymer or composite alternative, producing the most detailed, most defined, most forward treble character possible from the format. The trade-off is the characteristic titanium resonant peak in the upper treble — the energy that makes titanium sound bright and aggressive in the presence band.
For live sound applications, that brightness is a deliberate advantage. The B&C DE910TN’s titanium diaphragm projects high-frequency energy with maximum authority, cutting through ambient noise, distance attenuation, and competing sound sources with the kind of presence that composite and polymer diaphragms can’t match. The resonant peak adds energy in the 5–10 kHz brilliance band where vocal clarity, cymbal definition, and transient attack live.
The pure titanium construction also explains the 110 W AES power rating — significantly higher than the DE910’s 80 W. Titanium’s superior thermal stability compared to the composite diaphragm means it handles more power without mechanical compromise. The dome maintains its geometry and resonant properties at elevated temperatures, allowing B&C to rate the B&C DE910TN for sustained power levels that would risk delamination or deformation in a composite structure.
The shorting copper cap on the pole piece reduces voice coil inductance rise at higher frequencies. The resulting 0.14 mH inductance keeps the impedance curve flat through the 18 kHz upper limit — critical for a driver with a 75 mm coil that would otherwise produce significantly higher inductance without the cap.
The 0.5 kHz – 18 kHz frequency range is the widest of any compression driver in B&C’s HF range. The 500 Hz lower limit means the B&C DE910TN produces usable output in the mid-range — a full octave below the DE910’s 1 kHz lower limit and well below the frequency range where most compression drivers are physically capable of contributing meaningful output. This extended low-frequency reach opens up crossover options and system architectures that other compression drivers in the range can’t support.
At 2.4 kg, 131 mm overall diameter, and 52 mm depth, the B&C DE910TN is physically identical to the DE910. Same body, same weight, same four M6 mounting holes on a 102 mm bolt circle at 90° intervals. The two drivers are completely interchangeable in any cabinet — builders can choose between composite and pure titanium based on tonal preference and power requirements without modifying the horn or enclosure.
Performance and Applications for the B&C DE910TN
The B&C DE910TN delivers 108.5 dB sensitivity across a 0.5 kHz – 18 kHz bandwidth with a recommended crossover frequency of 1.2 kHz. The 108.5 dB is 1 dB below the DE910’s 109.5 dB — the pure titanium diaphragm is slightly heavier than the composite, which accounts for the small sensitivity reduction. In practice, 1 dB is a minor level adjustment on the amplifier or DSP — and the B&C DE910TN’s 37.5% more power handling more than compensates at sustained output levels.
At full rated power, the B&C DE910TN’s combination of 108.5 dB sensitivity and 110 W AES produces the highest sustained peak output of any compression driver in B&C’s range. The DE910 achieves 109.5 dB at 80 W. The B&C DE910TN achieves 108.5 dB at 110 W. When you do the maths, the DE910TN produces approximately 1.4 dB more sustained peak output than the DE910 despite the lower sensitivity — because the additional 30 W of headroom more than offsets the 1 dB efficiency difference.
The 110 W AES / 220 W continuous program power handling is the highest of any compression driver in B&C’s entire catalogue. For context, the DE550/DE550TN handle 70 W AES. The DE502 handles 50 W. The DE910 handles 80 W. The B&C DE910TN steps beyond all of them by a margin that leaves no question about which driver handles the most power in the range. For touring systems, festival rigs, and arena installations where the compression driver runs at sustained high power for hours, the B&C DE910TN provides thermal headroom that nothing else in B&C’s range can match.
The 0.5 kHz lower frequency limit is the most remarkable bandwidth specification in B&C’s HF range. 500 Hz is mid-range territory — a frequency band where most builders would use a dedicated midrange cone driver, not a compression driver. The B&C DE910TN produces usable output at 500 Hz from a 1.3-inch exit on a horn, which means system designers can cross the driver over as low as the horn’s cutoff frequency allows.
With the recommended 1.2 kHz crossover, the B&C DE910TN has 700 Hz of headroom below the crossover point. That’s nearly an octave of overlap with the woofer section — enough for gentle crossover slopes that produce seamless, phase-coherent transitions. In three-way systems, the B&C DE910TN can be used as a mid-range compression driver covering 500 Hz to 5 kHz, with a tweeter or super-tweeter handling the frequencies above. The bandwidth is wide enough to support multiple system architectures from a single driver.
The 1.2 kHz recommended crossover matches the DE910 and the DE550 as the lowest in B&C’s range. The 1.3-inch exit and 75 mm coil give the B&C DE910TN authoritative output in the 1–2 kHz presence band, where the horn controls directivity and the compression driver’s sensitivity ensures the system maintains consistent coverage and SPL across the listening area.
The pure titanium diaphragm’s bright, forward character is the B&C DE910TN’s strongest practical advantage for live sound reinforcement. Titanium projects. It cuts through. It maintains vocal presence and transient definition at distances and ambient noise levels where smoother diaphragm materials lose their edge. For touring sound companies, festival stages, and arena installations where the audience is far from the speakers and the air between them absorbs high-frequency energy, titanium’s aggressive treble character ensures the HF section delivers detail and clarity to every seat.
The 8 and 16 Ω impedance variants add system design flexibility that the DE910 doesn’t offer. The 16 Ω variant is essential for line arrays using multiple compression drivers per element. Two 16 Ω drivers in parallel present 8 Ω to the amplifier. Four in series-parallel present 16 Ω. These are efficient, standard impedance values that professional amplifiers handle without derating or thermal stress.
In systems with DSP, the B&C DE910TN’s titanium resonant peak can be shaped to taste — smoothed for more neutral reproduction or left untreated for maximum projection. In systems without DSP, the titanium character provides natural presence boost that helps the HF section cut through without requiring EQ processing.
Ideal applications for the B&C DE910TN include:
- Large-format touring speaker systems requiring maximum sustained HF power handling
- Festival rigs and arena installations where distance and ambient noise demand titanium projection
- Line arrays using the 16 Ω variant for multi-driver HF configurations
- Three-way systems using the B&C DE910TN as a mid-range compression driver from 500 Hz upward
- Two-way systems crossing over at 1.2 kHz for optimised directivity control from the horn
- High-SPL club installations running sustained high power through extended operating hours
- Active systems with DSP where titanium’s forward response provides headroom for voicing
- Applications where 110 W AES thermal headroom is the non-negotiable requirement

Conclusion – B&C DE910TN Compression Driver
The B&C DE910TN is the highest-power compression driver in B&C’s entire product range. The 110 W AES rating stands alone — no other B&C compression driver comes within 30 W of it. The 2.05 T neodymium motor is the most powerful magnetic circuit in the catalogue. The 0.5 kHz – 18 kHz bandwidth is the widest of any B&C compression driver, reaching a full octave deeper than the composite DE910 it shares a platform with.
The choice between the B&C DE910TN and the DE910 comes down to priorities. The DE910’s composite polyester/titanium diaphragm delivers 1 dB more sensitivity (109.5 vs 108.5 dB) and smoother treble with less resonant peaking — better for systems without DSP or applications where a more natural treble character is preferred. The B&C DE910TN’s pure titanium delivers 37.5% more power handling (110 vs 80 W AES), a full octave more low-frequency reach (500 Hz vs 1 kHz), 16 Ω availability, and the brighter, more forward treble character that cuts through in demanding live sound environments.
For the highest-power applications in professional audio — touring rigs, festival stages, arena installations, high-SPL clubs — the B&C DE910TN is the compression driver that handles more sustained power than any other driver B&C makes. The pure titanium diaphragm ensures that power translates into the most projecting, most present, most defined high-frequency output available from a 1.3-inch exit. One hundred and ten watts, 2.05 Tesla, 108.5 dB, and the kind of titanium treble that reaches the back row and refuses to be ignored.
