As a vintage audio lover, I’m legally obligated to ask what the speakers and amplifier are.

There's a pair of bookshelf speakers above the Luxman that are probably what it's driving. Very generic looking, those speakers could be almost anything. Maybe Tannoy Revolution R1 based on what appears to be an oval badge below the grill cloth?

The two speakers on their side are subwoofers, likely with JBL drivers, possibly in DIY cabinets. The Luxman can't possibly be driving them (not nearly enough power). The subs may not be functional and the cabinets are just being used as a table?
Here's a similar DIY subwoofer cabinet and drivers for sale:
