We literally started with a blank sheet of paper and engineered everything to offer the best possible reliability and performance. Many prototypes, re-designs and modifications were made and a tremendous amount of reliability testing was undertaken in order to ensure outstanding longevity. Using a custom designed flat wire coil and high specification Y38 magnets the Indy EVO is something very special, delivering performance way beyond expectation. The spiders are tuned to each exact model allowing us to develop for excellent excursion and power handling while implementing measures to prevent coil rub. The motor venting has been carefully designed to offer a good balance between noise reduction and cooling efficiency. The build of the woofer also incorporates some measures to add additional durability for extreme use. The high roll surround was chosen to allow to peak excursion while maintaining good cone area. In normal use the surround will not be put to its maximum limits - this helps to improve longevity. The added bead of glue above and below the coil helps to prevent separation of the coil when used in extreme situations. Oversized 4 AWG terminals make for easy installation and allow easy use of multiple cables to the one terminal when running multiple woofer configurations. Safe for use in almost any enclosure - bandpass, vented or sealed. Not for use in free air/infinite baffle configuration. For keen enthusiasts this woofer offers good musicality whilst maintaining great power handling and surprisingly good deep bass performance. Indy EVO is the ultimate iteration of the Swiss Army Knife subwoofer. We also offer recone kits for competition use.
IndyEVO concept was designed using the IndyS as a base point to offer an all-round Extreme performance woofer at a reasonable price point. The new engineering team drew up a list of specification points and made several prototypes before settling on the current configuration. From there detail changes were made to every aspect of the basic design focussing on each detail. Performance was optimised to allow the woofer to run well in almost any enclosure. The Indy EVO branding was originally conceived in mid-2019, with outline specifications in play
