#40 Sony GTK-XB90: $429 Discontinued eBay

Pros: Deep punchy EXTRA BASS technology for party use. 3x 2.36” tweeters + 2x 7.09” woofers, built-in LED lights sync with beat. 16 hours battery claimed (9 hours real-world at moderate volume with lights). Built-in handle, portable one-box design. Fiestable plugin controls party settings and DJ effects. Three-device simultaneous Bluetooth pairing. Measured bass extension of ~50Hz (-10dB).

Cons: Bass is muddy and not deep, weird midrange peak, rolled off treble and overall strange tuning. Discontinued.

How it compares: Just above it: Soundcore Rave - $209 cheaper, 8 more hours of battery life. Just below it: Sony GTK-XB72 - $80 cheaper, 7 more hours of battery life.
