Custom Crossover Networks
New crossovers for classic JBL, Altec, Tannoy and Great Plains speakers.
From $350 per pairTypical lead time 3–8 weeks
An old crossover is often the weakest link in a great speaker. We rebuild or redesign them with paper-in-oil capacitors, copper-foil and Jantzen inductors and proper attenuators, laid out on solid boards so you can see every part. Past work includes JBL LX5, N7000, N1200, 3110A and 3182 networks, Altec 604E in Crescendo cabinets, Great Plains 604-8E and Tannoy upgrades.
