My Pop had too much bass and sounded distorted so much some words from Alexa were hard to make out. This speaker fit the hole just fine after I cut out the old on with utility knife and soldered the wires.

They sound good for the size and are relatively sturdy. The soldering tabs are a bit fragile but when treated with care they should hold up fine.

Bought these to replace speakers in a bluetooth altec. I am unsure if these speakers are water proof from the front like the altec ones.The magnet in these speakers are smaller than the one altec uses. So I'm disappointed . I hear a slight difference but still bassy enough to match, especially with equalizer.At least it fit snug and was cheaper than most others but it's not for me so...Still, this deserves like a 4.5 star rating. Altec makes it easy to repair right now so yea these were a good replacement but I need a bigger drive/magnet and water proofing from the front but these dam sellers cant always or wont always put such spec details up
