hi folks looking for some lockdown advice as I'm not in a position to test this out at volume for a while... I've got a nice pair of ABM combos as in the pic. Its an ABM 300 1X10 and a NEO 400 1X15. The idea is to use the 110 for practice, the 115 for most gigs and then if needed pair them up as a rig. I tend to overthink this kind of thing but in terms of unmatched speakers, the 10nbeing a bit weak and potentially excursion limited etc ... can anyone convince me this is a good plan?? Or that I should sell them both and buy something else 😂

Slight zombie resurrecion here but just adding this in case it is useful for others ... I've had this confirmed by tech support at both Orange and Ashdown, and have scoped the ABM to confirm it. 1) Ashdown's ABM series has a steep HPF as standard, it starts to work at around 30hz. I was only told that the ABM that has the HPF, but haven't had a MAG or RM series amp to test. 2) All of Orange's bass amps (and the new Bass Butler preamp) have a steep HPF which starts to cut at 30hz. Includes everything from the crush range to the big heads. I don't know what order (db/octave) they are but they are described as steep and the purpose is to filter out subsonics without interfering with your sound /tone. It is hard to scope & measure accurately down below 30z, but it does look like a steep drop off on the ABM, so my guess (and that's all it is) would be that it is at least 18db/oct. In general, the more I learn the more I respect amp makers who have been doing this for years (decades), many of whom have already dealt with cone excursion problems in their amp designs.

Same here, no complaints sound wise but personally I'd prefer a larger metal pedal for roadworthiness.
