tkrestonva[TK] Posted May 13, 2010 Report Share Posted May 13, 2010 Where are your speakers located? If they are contained within the aerators (as in the kind Stomper used to sell here), then I'd go with the first option you listed. If you have a plastic toy Easter egg or something like that laying around, you can fill each half with some sound-dampening material (cotton padding?) and use the two halves to cap off the speakers from inside the helmet, with the wires running underneath the caps to your amplifier and mic.

thepoka Posted May 28, 2010 Report Share Posted May 28, 2010 (edited) I´ve never experienced any feedback problem but I stuck some blu-tack around the hole and the wires on the inside just incase, so that might be a tip for you Edited May 28, 2010 by thepoka Quote Link to comment Share on other sites More sharing options...
john danter Posted May 28, 2010 Report Share Posted May 28, 2010 (edited) I think I have a tutorial on here which shows how to successfully make in helmet speakers The trick is to limit the backward inward sound by several means. At first I tried aerosol caps and filled them with blutac. That worked great. Next step was for me to get my vac former out and make these Hollow out the helemt and superglue the hovi tips into the recess ---------- This way sounds prjects clearly outward -------- Also use one of these mics -------- Not one of the pad like things Bikers like to use. Feedback city with those Out of interest, I have some spare speakers and left over formed caps:) Edited March 25, 2022 by gmrhodes13 link removed no longer working Quote Link to comment Share on other sites More sharing options...
