tiny little tube amps through great big cabinets

I've really been enjoying my Vox ac4HW1 plugged into this old "super musical products" closed back 2x12 from the 80s that I have loaded with greenbacks at 16ohms. Its an oversized frontloader that I had been using with my HC30 for a while laoded with a Celestion Blue and a WGS Reaper30/55hz, but it was kidna boomy so I gutted the speakers for one of my AC30 combos and traded it. A year later she came back to me with greenies and now I am really liking her again. The boominess has been tamed a bit and she helps put some crunchy-cripsy-marshalliness onto everything she touches.... For overdrive this oversized, sealed cab driven by a cruddy 4 or 5 watts of single ended, class A power really sounds bigger than running a more powerful push/pull head (even an 18 watter) through this same cab and dialing the master back some to rein in your overall volume.... the whole exercise is making me miss my oversized marshall 4x12 cabs. I wonder if I fill one with 15 watt speakers if 5 watts will drive it alright? I am pretty sure that with greenbacks a 5 watt amp won't really tickle the voice coils enough to coax any tone from them, but blue or silver alnico speakers are pretty sensitive. Tempting to buy another TV and slap a buncha weber silver bells in there.... anyway!

Is anyone else running a really small tube amp turned up a lot through a bigger, closed back cabinet?

I acquired a new Vox AC10C1 a couple of months ago and I am happy with the stock 10" in the cabinet. This thing gets pretty loud for a 10 watt 10" speaker.

an ac15 puts out a solid 18 watts, a vintage ac10 really puts out 15 to 18 watts. There might be a little less voltage on the plates, but really the only difference between a vintage ac10 and ac15 is the cabinetry, speakers and the output transformer. They are almost the same amp. I'll bet this new RI is really smilar to the current Chinese ac15, just with less features. It probably kicks out close to 18 watts without difficulty but I will ebt the speaker is REALLY LOW EFFICIENCY.

I actually am really into the old 60s JMI ac10 2x10 combos with those Goodman's gold colored alnico speakers. They are sweet. I had a chance to score one a decade ago for a relatively cheap price due to some idiots at a guitar center thinking it was solid state I guess because you can't see tubes hanging down on an old vox (and also the back panel with the s/n and model was missing, but goddamn if I didn't know precisely what this amp was at a glance), but like a moron I tipped my hand to a clerk. See, this idiot was playing through it commenting on how good it sounded for a vox 'transistor' amp while screwing around with the voltage selector because he thought it was some kind of fucking attenuator! I don't know what this moron was thinking. I very well knew that if he kept dickering with the thing the power transformer would blow, and he would probably cause some catastrophic tube failures that might cause arcing across the sockets and a possible flame out, so I told him what it was and he went and got his manager. But it was the only way I could stop this meat head from breaking a lesser known vintage JMI Vox tube amp! I said I was interested in buying it and the asshole just kept 'demonstrating how cool it the amp was' like I didn't already know. Anyway, I had to get that rant off my chest! The only thing that makes me feel better aout that incident is that I couldn't afford the amp at the time even at their low pricing. It had not been so long since I had kicked out for my 62 ac30 and maybe a guitar or 2, so I was on gear-purchasing suspension while I paid some fucking bills.

But I too, am curious how it would be with a 2x12 or any larger 16ohm cab if i needed to fill more space. I do plan on getting a second AC10C1 and going stereo. Anyone out there using a similar setup ?

I always run 2 vintage or boutique ac30 or similar amps anymore, always
