DIY Crossover Tufnol Board Kits A range of components designed to offer the DIY enthusiast an inexpensive way of constructing / mounting crossover components in a compact and professional manner on 2.5mm Tufnol Board. Available in two formats.
      (1) Purchase the individual components, board + tags and do your own thing with holes etc. or
      (2) Make use of QTA's in-house layout and tag Turret Tag insertion into Tufnol crossover board insertion service.
In either case you get to assemble the crossover yourself.
Pins can be inserted from either side of the board but the best visual layout is achieved with the pins inserted on the reverse side of the board and the component leads threaded through the tags from the front. The centre hole has a nominal diameter of 1.19mm, so accommodates a maximum wire diameter of 1.0mm. Cable leadouts for drivers may be led out or pinned from either board face.
Also available for speaker to crossover connection, OFC multi-stranded TPE insulated copper cable in 2.5mm (for bass sections) and 1.0mm for (tweeters). Highly flexible and the insulation doesn't peel off when you solder it. Available in various colours, see table:-

Note:- Components mounted as per above are for illustrative purposes only.
