I dismantled some old bookshelf speakers, built an enclosure and added a bluetooth amp and rechargeable battery and I show you how I did it.
In this build video I didn't include any crossovers. I've since built a second speaker and salvaged the old capacitors that were in the positive lead to the tweeters. I just soldered the capacitors in the positive lead to the tweeters. I also salvaged the port tube and ported the back. The resulting sound is MUCH better!
