HELP MB Quart Tower Speakers Q-100 nr 1000?

Someone in town is offering these speakers for $150. I can't find any info online... Here are the specs he posted:

•Impedance: 4 Ohms
•Frequency Response: 33Hz - 32kHz
•Sensitivity: (1 watt @ 3") 87dB
•Tweeter: 1" Pure titanium, dome utilizing D-Link Isolation mounting
•Woofers: Dual 6.25" polypropylene cone/composite cast basket / butyl rubber surround
•Power Range: 110 - 180 Watts
•Crossover Frequency: 33kHz - 32kHz

Any help would be great!
MB Quart has made some nice sounding speakers. If they are in good condition I don't see how you can go wrong for $150. There isn't much out there for that price in a speaker with those specs.
Be careful and make sure they aren't automotive speakers. MB Quart makes a lot of car speakers. The rubber surround is less likely to degrade but may have issues. Can you audition them before purchase?
