B139B B110A T27A network, KEF Concerto, Falcon Acoustics with Falcon MH and HF upgrade. Recommended Upgrade. Super Power Low Loss Network version of Crossover 5c.
Supplied in Kit Form only. Price is for one crossover/network.
This Super Power network improves the performance of the original B139/B110/T27 units fitted to the KEF Concerto 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 on the existing PCB3. Full Instructions supplied.
