Great sounding speakers! They aren't the best, but awesome for the money. You can build a very high quality sound system with these since they are completely full range.

Generally speaking, gushing reviews of anything are kinda hard to believe - and even harder to trust. That said, I will reign in my review of this delightful FR speaker. I bought 4 of them (along w 2 134; tweeters) with the notion of building a.... hmmm...? Call it a line array/MTM/MTM active semi-portable bluetooth speaker thingy. That's close enough, I suppose. Anyway, to the point. This driver hits on every mark. It is accurate, detailed and very nimble - even at low volume. Bass notes are warm (not booming, of course) and possess a pleasant timbre that is nearly impossible to describe, but you sure as hell know it when you hear it. And all in a 3.5 FR driver for $15. This is gospel: if you are a DIY speaker builder/designer, you owe it to yourself to experiment with this driver.
