There's a popular YouTube video that compares this cab to a Mesa version with the UK Vintage 30's, and it is 100% clear to me that the Harley Benton cab had the two speakers wired out of phase, robbing them of all bass. In fact this cab has enormous bass when wired properly in phase. I will leave it to you to decide whether that was accident or intention. But I insist you disregard that video. They wouldn't sell any of these if they sounded like that.
These Vintage 30's are made in China, but they sound excellent. I had a pair of UK Vintage 30's for a decade that were a bit chimier than these in the mids. But I wasn't a huge fan of that chime. The Vintage 30 has become Celestion's flagship speaker. It's full range, well balanced, punches nicely, has decent detail through the mids...sounds nice on virtually any amp. The amp and guitar have controls that some players seem to have never discovered, and they hope somehow the speaker will compensate. No, learn your instrument. The speakers are a fairly subtle component of the chain, typically, and if not, they're tying your hands. The Vintage 30 is a genuinely all-purpose speaker, love it or not.
These cabs used to come front-loaded with the grill velcroed on. Here at the end of 2022 they are back-loaded and you will need to pull the back off to swap speakers.
For this absurdly low price, we can't have any other complaints. The cabinet is solid enough, the tolex not terrific but acceptable. They assemble these so fast the glue wasn't dry when they put the back on mine, and taking the back off required taking off the handles and using a soft hammer to tear the glued tolex (which even a razor couldn't reach). The grill cloth has waves in it. But no big deal, I already have the tweed and oxblood replacements ready to make this a much nicer look. They did the sawing for me for free, thanks.
The stereo/mono switch is handy not just for stereo but for easily converting this into your choice of 1x12's. If you load with different speakers, you can instantly hear just one of them, and swap to the other just with the jack. Great for recording versatility. Or you could do a fake Leslie if you have a stereo amp to run a plugin through.
I can understand the video as a desperation tactic to keep the cabinet industry going in light of this absurdly good deal. But go ahead and get this deal. And get the nifty Laney 2x12 as an open back option as I did. You have all the cabs you'll ever need then. And a nice set of speakers to start with.
