NEW tweeter add-on kits including the EL70 and FR125SR
These 2 kits allow the user to add the ERT26 as a "Super tweeter" to either the EL70 or the FR125SR. In both caese the main driver runs full range and the ERT is brought in to add high frequency "air" and detail. The included resistors allow a couple of level adjustments and the cap protects the tweeter from low frequecies.
