Mine is similar, a 32" Trinitron XBR, circa 1998. The front speakers are built-in on the sides of the screen, and it also has large woofers on the rear 'cone' of the case, but instead of facing up like yours, they are on the sides. Sound from it is awesome.
You can kind of see how the front speakers look here: http://www.atariage.com/forums/index.php?showtopic=147404
Got it the year before they started making flat-tubes. The downside is it's not a flat-tube, the upside being the flat-tubes used like 50% more glass, so they are ridiculously heavy.
And I agree, the Sony tubes are amazing for classic gaming. Plenty of inputs, (Including a front composite and S-video) and even a component input (which baffles me, since HDTV didn't exist yet)
