Uh... How many different bass amp heads are out there? How many cabs? Preamps? Effects pedals? There is just as much competition for their existing products as for combos.I want to see the pedalboards of all these guys who claim a cabinet and a head and a speaker cable is too much trouble LOL.
If you want a combo, that's fine there are TONS of choices out there, but don't expect every company out there to make combos; you can't not hit one swinging a dead cat.
Just perusing the Sweetwater site they offer 31 bass combos between 250 and 1,000 watts; and they don't even sell MarkBass, Phil Jones, or GR Bass.
Add in these guys and you are probably at 50+ bass combos north of 250 watts on the market.
That's your answer why Aguilar is reluctant to do this, a LOT of competition at all price levels and you have to sell that product to someone who wants your amp AND your cabinet.
That's less of an issue for say someone buying a Hartke or a Bugera but at the price point an Aguilar combo would cost the buyers get a lot more picky.

I don't think it is a big stretch to find people who want both an Aguilar head and cabinet, just as it's not hard to find people who want that from GK, Hartke, MarkBass etc.
It seems like they (still) don't think there is a big enough market for an Aguilar combo. Or maybe they don't think it's worth the effort.
