OBS Magnet Type Y38
Introducing the Bassface Indy EVO – 2end of many lines to be developed in our own facility here in the UK by our new engineering team. This is a brand new design is based on the new Indy S. The team engineered everything to ensure the best possible reliability while offering extreme 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 custom designed coils and spiders tuned to each exact model we were able to develop for excellent excursion, power handling and motor force 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. Dual leads add additional failsafe. The added black coating of glue on the coil prevents separation of the coil when used in extreme situations. This is a useful feature for those that use this woofer for SPL burps. Oversized 4 AWG terminals make for easy installation and allow easy use of multiple cables to the one terminal when running multiple woofer configurations. The suspension, spiders and build of this woofer along with the over specified X-Mech allow safe use in almost ANY enclosure; bandpass, vented, sealed - the IndyEVO will cope with them all. The single stipulation is that it WILL NOT work in a free air/infinite baffle configuration. For keen enthusiasts this woofer offers good musicality at an affordable price point whilst maintaining great power handling and surprisingly good deep bass performance. We also offer easy use recone kits that come with the shim tool needed at an affordable price for experienced users in competition scenarios.
