The ZA-SR71 is designed for Madisound by John Krutke of Zaph Audio. John is a true asset to the DIY speaker building community, and we are very pleased to offer you an easy to build kit based on his expertise. Detailed information about this system can be found on Zaph Audio.

Both drivers are from the Seas Prestige lineup. In our opinion, the Prestige line offers unparalleled performance for the price. The mid/bass is the ER18RNX (H1456), a 7” Reed/Paper Pulp Cone woofer with a copper shorting ring in the magnet system. This driver provides smooth response, excellent excursion and very low distortion. The tweeter is the extremely popular 27TDFC (H1189). This ferrofluid cooled tweeter employs a High Definition pre-coated fabric dome with a wide soft polymer surround. The optimally dampened rear chamber allows for a low crossover point.

This kit is designed for use in the finished MD14BP cabinet (.5cf, rear ported) with the pre-routed MD14-B4 baffle. The cabinets are sold in matched pairs and measure 9.1” W x 15.4” T x 11”D. Cabinets have real wood veneer and are available in Black Ash, Maple and Cherry finishes. Please choose one.

The ZA-SR71 kit includes everything you need for one pair of speakers, including assembled crossovers. A soldering iron/pen and screwdriver/drill are the only tools needed for assembly. As always, kit price as shown is the sum of the parts price with a 10% discount applied. (Cabinets do not receive discount.)

Updgrades

You may upgrade the series inductor in the crossover to a Goertz Copper Foil 14awg for an additional charge. Tube amp users should consider adding the impedance flattening circuit to the crossover. Both options are available above.

NOTE: If you choose to add the impedance flattening circuit, you cannot biwire/biamp the speaker.
