Madisound recommends:
- 0.55 cubic foot (15.5 ltrs) sealed, F3 70
- 1 cubic foot (28 ltrs) vented, 2" x 6“, F3 49
The GF series is designed for the discerning audiophile customer. To meet the needs of this audience, several new technologies were developed with the goal of lowering distortion and damping in the speaker. The coated fiberglass cone reduces vibration and standing waves, and the vented motor system minimizes power compression. The combined result is a very open and dynamic sound.
The 22W/4434G has the same frame size and should be considered as a replacement for the PL22WO09-04 or the MG22WO09-04. |
Recone kit for FPW8N8150
| The B&C Speakers 8NDL51-16 is an efficient and lightweight cast frame 8" neodymium driver. Its ventilated voice coil gap ensures long term power handling and reduced power compression, and a copper cap on the pole piece reduces inductance and extends high frequency response. The 8NDL51-16 is highly recommended for compact 2-way speaker systems or as the midbass/midrange element in high-output 3-way and 4-way designs.
