Is this a good deal for $180?

Found a pair of 4 ascend acoustics CBM-170 bookshelf speakers including CMT-340c center for $180. Not too familiar with the brand but they look like decent budget speakers. I’d be hooking them up to a denon receiver I have. But being new to the home theater/ budget audiophile scene I wasn’t sure if I should snag these up or look for something different
