Are big subwoofers viable for 2 channel music?

Hey sorry to revive the thread but now i am in the future space I mentioned. Its 32 x 34 feet x 8 feet basement. I am only doing music / hifi here no HT.

I am thinking of what subs to get. I got some dual gsg audio full martys for my HT and i love them. I wanted to know if I should go that route for this space or mix and match approach with multiple different subs. Looking to buy used to save money. I am in Canada. I have been all over canuck audio mart but can't find anything that I think is a good deal.

Normally I would say that if you like the gsg then I would go with the gsg. But your case may be a bit more complex. It appears that the gsg subs are passive so depending on what amp you use, you may not even have low pass capabilities not to mention any phase control. It will also depend on what main speakers you pair it with. If you are going to pair it with a full range floor stander that cycles quite low and use only a low pass filter then you will probably be not be using much of the subs potential. If you are going to pair it with a smaller main that doesn’t cycle low and use an active crossover then you should be good to go with the gsg, though I would go with the 18” over the 21”

Honestly I have thought of this same issue. I also have a large basement setup that is 95% two channel and 5% home theater. I have looked at large home theater subs (JTR captivator etc.) online and read up on them but almost no one uses them for two channel. I think they would be just as good for two channel but have no idea. I think there is very little crossover between the crazy custom HT crowd and the highend two channel crowd. I think you should let us know how it works lol.

Some subwoofer processing have multiple customizable EQ presents that can be set for HT and two channel as well as inputs for HT and two channel. While both systems can be connected only one system can be used at a time.
