FALCON ACOUSTICS MF& HF UPGRADE
It is possible to improve the performance of these networks for the original B139/B110/T27 units by (A) increasing the roll off of the B110A (SP1003) at high frequencies from 12 to 18db per octave and (B) incorporating a simplified version of the acoustic Butterworth section for the T27. With a little bit of work and squeezing of the components, it is possible to incorporate these improvements with this kit on the existing PCB3.
The No.5 network only will fit in the existing network cut-out. All other types are too deep and in the case of the modified ones too wide. The network edge connector is poor and relies on two tin plated surfaces making good contact. It is best to put the network inside the cabinet on the bottom at the back or on the back at the bottom and rewire with a decent cable. We recommend 76/0.2 mm.
