Or any KWD speaker of this class. I ordered this speaker: https://www.amazon.com/OontZ-Angle-...ywords=OontZ+Angle+Solo&qid=1623627150&sr=8-3 It’s just the right size. I removed the stock speaker and set it in the rear of the housing. No need to unsolder or remove it. I placed the new speaker inside against the speaker housing, then filled the housing with thick foam. To give a deeper sound and to keep everything from moving. The charge USB was routed beside the slot at the rear The male/male speaker connector was run through a hole in the back. When put back together and turned on, the sound is no comparison to the original. Clear with bass. I like a matching speaker and this just enriched the sound 150%.
