Product Description
Manufacturer Part Number: CF1025BMB
Well-suited to both bass and mid-bass applications, the new Celestion CF1025BMB particularly excels as a bass unit in compact subwoofer applications.
Celestion CF1025BMB 10" Professional Midbass Driver 8 Ohm
The Celestion CF1025BMB features a 2.5" multi-layer voice coil providing 300W power handling and 92.5 dB sensitivity with a frequency range of 45Hz to 5000Hz. The elastomer surround enables a longer Xmax compared to a conventional 10" mid-bass speaker, allowing the CF1025BMB to better reproduce lower frequencies. This makes the driver a natural solution for discreet, compact subwoofer applications. However, it also performs very smoothly up to 2kHz, making the CF1025BMB a great option for 2-way designs with the added advantage of exceptional low frequency performance.
In addition to the extended low frequency performance, features include Celestion's smart airflow vented magnet assembly for dynamic heat dispersion to minimize power compression during operation; and an optimized T-pole magnet assembly to maximize the stability of cone movement for enhanced Bl symmetry, translating to lower distortion.
Developed at Celestion's headquarters in Ipswich, England, this loudspeaker is designed using specialist in-house software deploying FEA (Finite Element Analysis) modelling techniques, enabling the Celestion engineering team rapidly to achieve genuine increases in performance, that translate into greater product longevity, and exceptionally low distortion. This new high-performance cast aluminum loudspeaker is another example of Celestion's continuing commitment to delivering a wide range of high-quality solutions for sound reinforcement and professional audio applications.
Well-suited to both bass and mid-bass applications, the new Celestion CF1025BMB particularly excels as a bass unit in compact subwoofer applications.
