DENON Subwoofer DSW-5L-M

Purchased new approximately 22 years ago. It was used as a subwoofer for 5.1ch surround sound, but I am now selling it as it is no longer in use. There are almost no noticeable scratches or dirt. It is in perfect working condition. The bass sounds great.
How about using it as a subwoofer? Please understand that this is a used item before purchasing.

A bass-reflex type subwoofer equipped with a digital amplifier with a maximum output of 140W.

Crossover frequency: 50-200Hz
Playback frequency range: 30Hz-200Hz
External dimensions including the base are 220 x 380 x 510mm (width x depth x height), and the weight is 11.4kg.

Thank you for looking.
