Beyma 15MC500: 15" midrange with 500 W AES, 98 dB and 8 mm Xmax
The Beyma 15MC500 belongs to the MC series and is a 15" midrange driver with a 2.5" voice coil, 500 W AES and 98 dB sensitivity. Its working range of 50 to 4,000 Hz makes it a candidate for the lower-mid and midrange section of 3-way PA systems, but also for 2-way tops running above a subwoofer.
What separates it from pure mid drivers is the excursion: 8 mm Xmax on 880 cm² of cone area gives a displacement volume of 704 cm³. With Fs 46 Hz, Qts 0.45 and Vas 134 l the EBP lands at 98, so the driver sits right at the boundary where bass-reflex and sealed boxes both work. A BL of 18.3 Tm on 98 g Mms still keeps the system tight.
Use and enclosure
If you want to use the 15MC500 as a mid-woofer, the bass-reflex guide value is about 203 l tuned to 40 Hz with an f3 around 37 Hz. That is a lot of volume, but it extracts real lower-end output from the driver. For the midrange role in a 3-way system a sealed midrange chamber of about 91 l with fc at 72 Hz is the more sensible route; the crossover to the bass section then sits well above the lower limit of 50 Hz. The exact design is a job for the enclosure calculator at 42.audio.
The usable range ends at 4,000 Hz, where a compression driver on a horn takes over; with 98 dB sensitivity the 15MC500 matches Beyma high-frequency solutions well in terms of level. Keep the mounting depth of 170 mm and the weight of 6.2 kg in mind when building the cabinet.
What to look out for
- 8 Ω nominal, Re 5.6 Ω: a standard load for PA amplifiers.
- 2.5" voice coil rated 500 W AES: sufficient reserve for continuous operation.
- Xmax 8 mm, Vd 704 cm³: more excursion than typical 15" midrange drivers.
- Le 1.1 mH: allow for impedance compensation in the crossover at 4,000 Hz.
- Mounting depth 170 mm, weight 6.2 kg.
Frequently asked questions
How does the 15MC500 differ from the 15MCS500?
Both share cone area, the 2.5" voice coil, 500 W AES and 98 dB. With Qts 0.45 the 15MC500 has the slightly tighter alignment and the higher EBP of 98, which makes it marginally better for bass-reflex and lower-mid duty. Which version you choose depends mainly on the planned enclosure.
Can the 15MC500 run without a subwoofer?
In a bass-reflex cabinet around 203 l tuned to 40 Hz it reaches an f3 of roughly 37 Hz as a guide value and delivers solid lower-end output. If you want to build more compactly, plan a subwoofer and cross the 15MC500 above 50 Hz.
Which amplifier makes sense?
With 98 dB sensitivity you need little power for normal levels. To exploit the 500 W AES the amplifier should deliver corresponding power into 8 Ω; a limiter protects the coil during continuous operation.
