Short answer: the Sony GTK-XB90 for better sound quality, the Sony GTK-XB72 for the lower price. The Sony GTK-XB90 ranks #46 of 50 party speakers at $429. The Sony GTK-XB72 ranks #47 at $349, $80 cheaper.
The case for the Sony GTK-XB90: Deep punchy EXTRA BASS technology for party use. The tradeoff: Bass is muddy and not deep, weird midrange peak, rolled off treble and overall strange tuning.
What the Sony GTK-XB72 offers: Exceptional sound quality, powerful bass, vibrant multi-colored LED lights. Watch for: No deep bass at all, weird midrange peak, rolled off treble and overall strange tuning.
Buy the Sony GTK-XB90 if sound quality matters more than the price. Buy the Sony GTK-XB72 if the price matters more than sound quality.
If sound quality matters at all to you, skip both of these and look higher up the 50 party speakers instead.
