The AH! 1000 horn is made for one inch throat compression drivers like the JBL D175 (2410 series Drivers) and modern drivers such as the B+C de250 and the RCF 1411 1” drivers neodymium magnet. The JBL D175/2410, the Altec 802 / 808 drivers are all excellent examples of a high quality 1” driver. The aluminum diaphragms and precision machining are the properties that make these drivers a must. These drivers are relatively inexpensive, small and the crossover point of 1500hz does not require a large size horn. If true high fidelity is your goal in a very small package, this is the horn for you. A future small enclosure with a 10" woofer, the horn mounted in the woofer enclosure will be forth coming. Suitable free standing or built into a modest sized enclosure, crisp sharp transients are handled with ease and grace. Perfect where space is at a minimum, but true horn sound is required. May be used in large 3-way systems.
