Beyma CD-2514Nd/PT: 1.4" neodymium driver with BL 8.5 Tm and 54.7 mm mounting depth
The Beyma CD-2514Nd/PT is all about the motor: a neodymium system with a BL of 8.5 Tm drives a 2.5" voice coil beneath the PT diaphragm, and the 1.4" exit leads to the horn. Power handling is 80 W AES at 8 Ω, the working range extends from 600 Hz to 20,000 Hz. At 1.8 kg and 54.7 mm mounting depth, this is a driver that also fits into cramped enclosures.
The PT variant sits between the PK version and the titanium model of the same Nd family; all three are rated identically and differ only in the diaphragm. That keeps the decision pleasantly simple: first you commit to weight and depth with the neodymium motor, then you pick the diaphragm by taste. At 42.audio you will find all variants with a data comparison in the driver database, plus the Beyma horns to go with them.
Use and enclosure
A typical use is the two-way stage monitor: shallow, light, with a 12" woofer and this driver on a 1.4" horn. The 54.7 mm mounting depth helps in a wedge just as it does in a slim top. Horns with a 1.4" interface are in Beyma's horns and waveguides category; from 18SOUND, the XT1464, XR1464C, XR1496C, PR614 or the H860 3D Print fit, each with a 1.4" throat.
The crossover belongs well above the 600 Hz lower limit, with a steep high-pass. Because a stage monitor often runs close to the feedback threshold and takes tonal peaks in the process, a limiter in the HF branch is sensible; the 80 W AES is a continuous rating, not an invitation for amplifiers with unrestrained output. With a passive crossover, the 8 Ω make component sizing straightforward.
What to look out for
- Neodymium motor with BL 8.5 Tm: stronger than the ferrite version of the same family.
- 1.8 kg: light enough for touring and monitor cabinets.
- 54.7 mm mounting depth: fits shallow enclosures and wedge monitors.
- 2.5" voice coil, 80 W AES: set the high-pass steep and well above 600 Hz.
- 1.4" horn interface: combine with 1.4" horns only.
Frequently asked questions
Is the CD-2514Nd/PT suitable for stage monitors?
Yes, the combination of 1.8 kg, 54.7 mm mounting depth and a 1.4" exit is attractive precisely for that. A wedge stays shallow and portable. Cross well above 600 Hz with a steep filter and a limiter, and the driver will cope with hard monitor duty.
What separates PT from PK and Ti in the CD-2514Nd range?
Only the diaphragm. Motor, 2.5" voice coil, 80 W AES, 8 Ω, weight and mounting depth are identical across all three. Ti is the titanium diaphragm, PK and PT are the two other diaphragm variants, each with its own tonal character.
Do I need a special amplifier for the CD-2514Nd/PT?
No, any channel that works cleanly into 8 Ω will do. The actual power in the HF branch is low with music. What matters more is a steep high-pass and a limiter to protect the driver from low-frequency signals and clipping.
