Edited after using the cab live a lot :-)
There are many better cabs out there, but none for the money. If you aren't a gear snob or tone hound and have realised that probably 99% of your audience really don't give a monkey about the nuance of sound but just want to dance like loonies and don't want to wince with any harshness in the sound.
Welcome to my world. Boutique cabs cost more before they start earning. My gear has to earn. I needed to reinforce our sound. Not 'make louder' but reinforce.
Combo on a beer crate behind me, extension cab on the other side of the stage on a beer crate. I'd been borrowing a Marshall 50watt combo + 1x12 which sounded no better. If we need louder, we mic up.Seems gear snobs and thieves like Marshall. I'm HB-80R+ this cab now and we still sound AWESOME! for less than the cost of just the stolen cab.
Construction wise, it classes as adequate. It's an MDF chassis and mine had a footprint on the inside...Who cares! It is adequate. Interesting to note how the audiophile hi-fi lot used to witter on about how much better the sound from MDF cabinets compared to ply was, yet in the guitar world, MDF is treated as a joke. There's MDF and mdf I guess. This passes muster for MDF as opposed to barely compacted wood dust in glue.
The speaker has no identifying marks on mine. It makes a sound. Not a very nice one at first, but run full power for 10 minutes and it smooths out.
It has now spent some hours making some very high volume levels indeed, and those volume levels have been unperturbed by unwanted cabinet colouration or speaker distortion. Think of it as running the cone in, like you'd an old engine that'd been reconditioned. As it has softened up, so has any brittleness about the edges of the sound. The speaker is a good match for the Celestion Seventy/80 in the combo. Less bass and perhaps a little harsher but nothing of consequence. There are no strident overtones or pockets of missing frequencies, just a damn fine sound. No nasal honkiness when chunking and chopping either.
The cab is open back and reflex ported. There are no tubes, but is ported. This is a hint. You can place the cab near a wall or even gaffa stiff card at a pinch to make it a closed back. Bass beefs up as a result.
Same with open back combos. Make a closer for tighter bass.
The corner guards aren't fitted too neatly, but really, it makes a nice sound so who cares?.
For playing with amp heads for practice. As a cab, as an amp extension speaker, you'll not get better without spending big coin. The Vintage model may be more refined, but this has cojones. If you sip tea from a cup, go vintage model. Me?, I gulp from a mug
