Unfortunately Etsy policy is handmade only, so I am unable to sell non-customized speakers. We are working on building specialized hardware to offer with our devices, but that is in development and we have no specific date for offering it at this time. Apologies!
We can recommend speakers that we like though:
1. This one is our first choice: 10watt Power Amplifier – MR1506 (Amazon affiliate link) It’s loud enough to be heard during conventions or outdoors. Is pretty clear for being understood through armor or pouches. Great choice. You get what you pay for. 😉
2. This JBL GO2 Speaker has a very high quality sound and is a little less expensive. The difference is that it is not quite as loud as the other. If you aren’t going to large events with your costume, this would be enough to work fine.
