Impulse bought a JBL PartyBox 520. Found it on eBay with a $128 coupon discount (so like $511) so the price was right. I can probably sell my 100 for over $200 (which is what I paid like 5 years ago) so there's that. We'll see. It is a heavy sucker at like 58 lbs. 400W when plugged in. Removable battery. Dual 7.5" woofers + dual 1" tweeters. Sweet.
I still like my 100 but I guess I want to annoy my neighbors more.
And if I ever do my outside movie fantasy, I could buy a second and probably have some pretty damn decent stereo audio.
