I had that 1533+1203 stack right around winter/spring 2018, and only for a couple of months. I moved the 1533 and ordered a Changeling 212.So if I’m going to go for overkill I should just stack another 1533 on top?![]()
The 1533+1203 sounded like a fine match to me. When I pressed bandmates for opinions comparing a Baer ML112x2 stack to the 1533+1203 (with the Ashdown ABM500 "flat", meaning shape and e.q. off), the most direct comment was "[ML112] sounds warmer, [Hathor] sounds more punchy".
I think the bright, high-mid heavy Baer was a better match for the kinda-dark sound I get with the Ashdown. That might be where he heard "warmer".
The difference I'm pretty sure we all know is that the 15 driver is more efficient than the 12. I think Duke's previous comments were something along the lines of "212 gets as loud...but takes twice as much power to get there".
I didn't feel held-back by the 1203 when using it with the 1533.
There's a glaringly obvious Hathor family vibe. The difference in voicing, I think, is that the 1203 is more even through the mids, but with more high-mid presentation. The 1533 seems extra low-mid heavy and darker. Duke wrote that what I hear as "darker" is partly due to reduced vertical dispersion with the stacked 3" mid drivers.
Maybe another factor is the flat ABM500 voicing with the 1533 could be a "too much of a good thing" scenario.
With the 1533, I got a strong and quick bap!-bap!-bap! effect with aggressive pick playing, where the 1203 might have been less punchy and a version of grindy that seemed to come from a higher frequency.
I used a Walkabout for a few years before the ABM500. Memory and guessing says the Walkabout might achieve better synergy with the 1533.
If I had to do it again with a Walkabout or an ABM500, I would add a 1203 to a 1533 (instead of another 1533), mostly because I prefer the 1203 sound. And I would like the option/variety of having two different cab sizes.
Also, there aren't many situations where I could really crank two 1533s. I'm basing that assumption on my experience with the 1203 and Changeling 212. Even outdoors (with a WD-800 or the ABM500), just the 212 was plenty.
However, even really pushing it (~300-400W), the 1203 alone wasn't enough on a small stage with PA support.
I liked pushing the Walkabout a bit into the gnarl. I can see why someone who wants loud and clean might opt for a second 1533.
It's worth mentioning again that my comments are based on 3-years-old memory and some guesswork.
