Does your classical music listening have a lot of pipe organ? Neither of the subs you mentioned in your OP will give you true 20hz and below output. Each will roll-off much earlier and will be helped by any room gain.

If you really want low distortion, high output pipe organ you will have to spend a bit more money especially if you have a large room to fill.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
