IndyS15/2 15" 2x2Ohm DVC 1750WRMS Premium Deep Bass Subwoofer For Sealed Or Ported Enclosures


World RRP: £199.99

Category: SUBWOOFERS

Product code: IndyS15/2

Introducing the Bassface Indy S - first 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 - not a single part of the Indy S is carried over from previous models. We literally started with a blank sheet of paper and engineered everything to offer the best possible reliability and performance for a woofer at this price point. 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 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. Dual leads add additional failsafe. The added bead of glue above and below 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 IndyS 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. Indy S is the Swiss Army Knife subwoofer. We also offer easy use recone kits that come with the shim tool needed at an affordable price for experienced users in competition series.

Version History


Indy S concept was designed to offer an all round high performance woofer at a reasonable price point. The new engineering team drew up a wish list of specification points and made several prototypes before settling on the current basket, motor and cone layouts. From there detail changes were made to almost 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 S branding was originally conceived in mid 2019, with outline specifications in place by the end of that year. Prototypes were built throughout early 2020 and first production models were made available Q3 2021
