Today, let's have a look and listen to the speakers you see above.These Tannoy REVEAL 501a, though discontinued now and replaced with the newer Tannoy REVEAL 502 released in 2014, have been well-regarded over the years in home studio use (check out some user reviews here and on Amazon). They were first released back around 2010 and there's a good Sound On Sound write-up from mid-2011. These were budget priced at <US$500/pair on release (typically sold as individual speakers) although over the years, could be found for a relative steal down at US$200/pair.
These are biamped powered speakers - 40W mid/bass and 20W tweeter, unknown without opening them if these are Class A/B or D amps. There's a 1" soft dome tweeter, 5" mid/woofer, flared front port, and the box is MDF with curved front baffle. Dimensions are 11.9" x 7.3" x 9.4"; relatively small speakers. Each box is individually powered unlike the AudioEngine A2 or Edifier S2000 Mk III previously discussed where there is a cable tethering the speakers together, weighing about 6kg and quite solid in the hand.
