The Testarossa Loudspeaker Kit, by Jeff Bagby

Name: Testarossa Loudspeaker Kit
SKU: TEST
Price: 1680.94 USD
Availability: InStock

When we published this kit in mid-2018, Jeff’s Testarossa system had been running for about 4 years. Jef is a prolific builder and not too many systems stay in his listening room. But, the Testarossa had remained in his collection the longest.

This kit was a result of Jeff’s curiosity with the RAAL tweeter design, which started with the Auricle – TM. What he found interesting was the tweeter’s internal transformer section. It could be manufactured to start a natural roll off. Then, combined with the passive network components, it gave the desired slope. As a result, the crossover has two components in the tweeter section.

The woofer section has just two components. The smooth, extended range of the Satori woofers allows this benefit. Combined, this lets you have premium parts without a big increase in the total cost.

The cabinet is 8.5″ wide, 39″ Tall, and 13″ Deep.
