BEYMA 10G40: 10" guitar speaker with 3" voice coil and 400 W AES
The BEYMA 10G40 is a 10" guitar speaker from Beyma's G series, built for combos and cabinets where a single ten has to take more punishment than usual. A 400 W AES rating and a 3" voice coil are unusually generous for this format; most guitar speakers of this size run considerably smaller coils. The large coil offers more wire surface and therefore better heat dissipation, which makes it interesting for down-tuned guitars, baritone or loud stages with powerful amplifiers.
With 95 dB sensitivity and a range of 45 to 4,000 Hz it delivers what a guitar speaker should: solid fundamentals, defined mids and the typical high-frequency roll-off that makes distortion sound musical rather than harsh. The resonance frequency of 45 Hz is low for a ten; a Qts of 0.3 and a BL of 14.2 Tm point to a tightly controlled motor with plenty of force.
Use and enclosure
In the guitar world the cabinet shapes the character: open back for an airy presentation, closed box for tighter, more direct bass. The Thiele-Small parameters give you guide values for more deliberate planning: vented about 23 l tuned around 56 Hz with f3 near 63 Hz, sealed about 11 l with fc around 106 Hz. An EBP of 112 favours a vented or larger open-back enclosure over a small sealed box if you want low-end extension.
You do not need a crossover in classic guitar use: the speaker runs straight off the amplifier and limits its own top end. If you want to use it in a bass cabinet or as a low-mid driver with a tweeter, set the crossover well below 4,000 Hz. Work out the exact enclosure with the box calculator at 42.audio; the driver database supplies the parameters.
What to look out for
- 8 Ω impedance, Re 6.3 Ω: pick the matching output tap on valve amps
- Mounting depth 156 mm, more than many 10" speakers, check cabinet depth
- 5.7 kg due to the large ferrite motor, bolt it properly in a combo
- Xmax 6 mm and 3" coil: handles low tunings and bass content
- Le 1.4 mH: relatively high inductance, adds further top-end damping
Frequently asked questions
Does the 10G40 fit a 2x10 cabinet?
Yes, as long as the cabinet depth accommodates the 156 mm mounting depth. With two 8 Ω drivers, parallel or series wiring gives a different total impedance that your amp has to handle at the appropriate tap.
Which amplifier suits the 10G40?
At 400 W AES it handles more than most guitar amps deliver. The sound matters more: a lower-powered amp drives the speaker cleanly and without risk. Its 95 dB sensitivity means even mid-sized combos get loud enough.
10G40 or 12G40?
The 12G40 brings more sensitivity, more power handling and the classic 12" voicing. The 10G40 is more compact, has more excursion at 6 mm Xmax and therefore also suits low tunings in smaller cabinets.
