B&C 10PS26 – Versatile 10-Inch Ferrite Woofer with Extended High-Frequency Response
The B&C 10PS26 is B&C’s balanced ferrite 10-inch woofer — a 96 dB, 350 W AES driver with a 55 Hz – 4000 Hz bandwidth, a 76 mm aluminium voice coil, and a shorting copper cap that keeps the high-frequency response smooth and extended well into the upper mid-range. Where the 10MD26 chases extreme motor dominance at the expense of excursion and weight, the B&C 10PS26 delivers a more practical combination of output, displacement, and enclosure flexibility that suits a wider range of speaker designs.
The shorting copper cap on the pole piece is the feature that sets the B&C 10PS26 apart from most 10-inch woofers. It reduces voice coil inductance rise at higher frequencies, flattening the impedance curve through the upper operating range and allowing the driver to maintain smooth, extended output up to 4000 Hz. Without the copper cap, the response would roll off sooner and less predictably — the cap keeps the treble behaviour clean and usable through the crossover region.
With a Qts of 0.29 and an EBP of 164 Hz, the B&C 10PS26 works well in vented enclosures while retaining enough alignment flexibility for builders to explore different tuning strategies. B&C recommends a compact 25-litre vented enclosure tuned to 65 Hz. At 6.05 kg, it’s lighter than the 10MD26 mid-bass specialist but heavier than the ultralight 10CLA64 — the practical middle ground for builders who want ferrite reliability with professional performance.
Design and Construction of the B&C 10PS26
The B&C 10PS26 uses a 76 mm (3-inch) aluminium voice coil wound on a glass fibre former. The 3-inch coil diameter matches the 10MD26 mid-bass driver, but the motor behind it is deliberately different — designed for balanced performance rather than extreme sensitivity. The 18 mm winding depth operating in a 10 mm magnetic gap yields 5.5 mm of linear one-way excursion (Xmax) with an additional 5 mm of travel (Xvar) before mechanical limits. That 5.5 mm Xmax is more than three times the 10MD26’s 1.5 mm, giving the B&C 10PS26 substantially more low-frequency displacement capability.
The motor uses a ferrite magnet in a T-pole configuration, producing 0.9 T of flux density and a force factor (Bl) of 14.1 Tm. The flux density is lower than the 10MD26’s extreme 1.45 T, and the resulting 1.8% efficiency reflects the B&C 10PS26’s different design priority — this driver trades peak sensitivity for more usable excursion and a lighter, more cost-effective motor assembly. The 33 g moving mass keeps the driver responsive and efficient within its design parameters.
The shorting copper cap on the pole piece reduces inductance-related impedance rise in the upper frequencies. This is a premium feature that directly improves the B&C 10PS26’s high-frequency extension and smoothness — the output stays controlled and usable up to 4000 Hz rather than rolling off and becoming erratic as the voice coil inductance increases with frequency.
The exponential cone profile supports pistonic behaviour into the upper mid-range. The cone has no waterproof treatment, keeping mass minimal. A single spider handles suspension, paired with a double-roll surround. At 6.05 kg and 123 mm deep, the B&C 10PS26 is compact and manageable — lighter than the motor-heavy 10MD26 (7.25 kg) while still carrying a substantial ferrite motor with a 3-inch coil.
Performance and Applications for the B&C 10PS26
The B&C 10PS26 delivers 96 dB sensitivity and 1.8% reference efficiency across a 55 Hz – 4000 Hz bandwidth. The sensitivity matches the 10CLA64 neodymium woofer exactly, which means the B&C 10PS26 produces the same output per watt from a ferrite motor — at roughly a third of the neodymium driver’s price point. For budget-conscious builds where neodymium weight savings aren’t critical, the B&C 10PS26 delivers equivalent sensitivity from a proven ferrite platform.
The Thiele–Small parameters show a versatile alignment profile. A Qts of 0.29 and an EBP of 164 Hz place the B&C 10PS26 in vented territory with enough flexibility for builders to tune for different output characteristics. B&C recommends a 25-litre (0.88 ft³) vented enclosure tuned to 65 Hz — a compact cabinet that fits the 10-inch format and targets mid-bass punch in the 70–300 Hz range. The 55 Hz lower frequency limit extends 20 Hz deeper than the 10MD26’s 80 Hz, giving the B&C 10PS26 usable output further into the upper bass region.
The 4000 Hz upper bandwidth, extended by the shorting copper cap, gives the B&C 10PS26 crossover flexibility that most 10-inch ferrite woofers can’t match. You can cross over to a compression driver or tweeter at 2.5–3.5 kHz with substantial overlap, or use the driver in a two-way system where the woofer handles everything from the upper bass through the vocal frequencies. The copper cap ensures the handoff stays smooth and predictable.
Ideal applications for the B&C 10PS26 include:
- Compact two-way tops and stage monitors for portable PA
- Vented 10-inch cabinets for live sound reinforcement and DJ systems
- Three-way systems where the 10-inch handles mid-bass and lower mid-range duties
- Budget-friendly builds where ferrite pricing is preferred over neodymium
- Applications requiring smooth extended HF response through the crossover region

Conclusion – B&C 10PS26 Woofer
The B&C 10PS26 is the practical all-rounder in B&C’s ferrite 10-inch range. It matches the neodymium 10CLA64 on sensitivity at 96 dB, delivers more excursion than the 10MD26 mid-bass specialist by a factor of nearly four (5.5 mm vs 1.5 mm), and extends 20 Hz deeper into the bass than the MD26 can reach. The shorting copper cap gives it smoother, more extended high-frequency response than any other ferrite 10-inch woofer in B&C’s range — a premium feature that directly improves crossover behaviour and vocal reproduction.
The B&C 10PS26 doesn’t chase the extreme motor dominance of the 10MD26 or the featherweight portability of the 10CLA64. Instead, it delivers a well-rounded combination of sensitivity, excursion, bandwidth, and power handling that makes it suitable for the widest range of 10-inch speaker designs — from compact two-way tops to stage monitors to three-way systems. The 25-litre enclosure keeps cabinets small, and the 0.29 Qts provides enough alignment flexibility for builders to tune for their specific application.
For compact PA tops, stage monitors, budget-friendly two-way builds, and any application where a 10-inch ferrite woofer needs to deliver 96 dB sensitivity with genuine excursion, smooth extended HF, and professional power handling, the B&C 10PS26 is the ferrite 10-inch that gets the balance right. The shorting copper cap is the detail that separates it from the competition — and the reason vocals sound present and natural rather than muffled and rolled off.
