La série LVGC™ regroupe des haut-parleurs basse fréquences de forte puissance. Ils intègrent la technologie Vented Gap Cooling pour un meilleur refroidissement et une structure d’aimant améliorée
Symmetrical Field Geometry (SFG). Ceci permet d’optimiser la densité
de flux pour diminuer la distorsion harmonique du haut parleur. En évitant ainsi l’utilisation de métaux rares, ces haut-parleurs offrent des performances élevées pour un coût mesuré.

Positive voltage on BLACK terminal gives forward diaphragm motion.
1AES standard (60-600 Hz).
2Sensitivity is based on a swept 100 Hz to 500 Hz signal. 1 W is 2.83 V @ 8 ohms, 4.0 Vat 16 ohms.
3Frequency range is defined as the frequency extremes where the response is - 10 dB from the rated sensitivity.
4 Power compression is the sensitivity loss at the specified power, measured from 60 to 600 Hz, after a 5 minute AES
standard (60-600 Hz) pink noise preconditioning test at the specified power.
5Distortion is measured at - 10 dB power, from 100-500 Hz.
