My pair of Heybrook HB3 Mk2s, in black ash. There is little or nothing at this price that sounds as good as these, especially the definition of the bass. As they are a sealed box design there is no boom or overhang, they just don't go as low as some ported designs. But you can place them close to the wall behind to reinforce the bass without compromising the clarity.
The mids have been refoamed, and the electrolytic caps in the crossovers replaced with Mundorf polypropylenes, so should now last forever.
The cabinets are in good cosmetic condition, with a few scratches that I managed to make almost disappear, using black wood dye (not woodstain).
I made new grilles with acoustically transparent polyester material on MDF frames with rounded edges. You can see though them slightly, depending on the lighting. They are held on with velcro, so come off easily.
There is also a pair of 21cm high stands, made with solid beech wood legs and MDF tops. The bottoms of the legs are threaded, for spikes, which you can also have. Also a couple of cardboard boxes made to fit them for transporting them, but not suitable for trusting to a courier, so pick-up only. I am in Plymouth, but I could deliver them for the cost of the fuel, within a reasonable radius.

I am asking £300 for them.

(I am raising funds for a Townshend Allegri+, trying to simplify my system. It's too complicated for my wife at the moment.)

Those look very nice. It's a lot of speaker for the money. Good luck with the sale!

A little anecdote, for your amusement.
Although absolute phase/polarity is something that many don't believe in, I have heard it. But only once, many years ago, and it was with these speakers. I had been moving things around, and playing a particular record something sounded off. The bass just didn't sound as it had before, so I re-checked all my cabling and found that for some reason I had reversed the speaker cable polarity. Both speakers, obvs, so I returned them to their original orientation. And the bass was back to normal! It was on bass transients* on kick drum, and what had sounded like "foob" went back to "boof". Weird, but repeatable and heard by others too, once it was pointed out. Sealed box bass: not as deep as some, but very clean. Never heard it with any other speakers, or any other music. Different house, amps, source, etc. now, so I can't replicate it, but they still sound so sharp in the bass.
* Transients, of course, are higher in frequency than the bass, but make the bass sound fast, or slow, depending.

Withdrawn. I have decided to keep them, as they sound too good!
