Starting with the motor design, we spent a lot of time optimizing the design to incorporate a large inner pole, upper and lower, Faraday shorting ring which helps to reduce any distortion caused by inductance throughout the movement range of the cone. We chose a 2.75” diameter coil that has a very long winding width, with the wire being made of flat aluminum. Overall, they have 19 - 27mm of excursion one way at 70% BL and have a 35mm of X-mech forward and 50mm downward x-mech clearance before soft parts crash into hard parts. The motor utilizes a vented pole design with coil gap radial vents for moving heat quickly out of the gap. Mated to the motor is a heavy duty cast aluminum frame that serves as an excellent heat exchanger. As the motor gets hotter the mass of aluminum helps to dissipate the overall heat. Nomex spiders with heavy stitched in tinsel leads connect with the competition grade treated paper cone, and the heavy-duty foam surround that complete the make-up of this woofer.

Is it Really made in USA? Boss Audio CLR60 by Zed Audio NEW IN BOX Hi-Fi re-do 2025-12-28 | In this video I open up a old school Boss Audio car amplifier That has been in its box since 1998. This new in box amp was made by Zed Audio in the USA. Is this budget amp and piece of junk or a nicely build amplifier? I will give it a sound demo, amp dyno, and gut shot of the internal components. The plexi top is really amazing, and the finish looks great. Hard to believe this was only $199 back in the day. This is part 5 of a 5 part series of USA made amps that might be a bit on the cheaper side. link to series belowyoutube.com/playlist?list=PL94MyhAPM3QhVPmAbISPF8pqgjqvwIdpxFollow the channel on Face book.@HiFiReDo Pick up a channel sticker hereebay.com/itm/226370377946
