Passive Sub? -- Renovating an audio system just out of storage

[T Moon]

I am in need of any advice on acquiring a passive sub that will be driven by a 360W dedicated amp. At this point, I <think> I am leaning toward 10" - 12" driver.

Room is a very hard surface 14' x 14'. One wall is primarily glass, one wall is open to another space, the other 2 walls and ceiling is painted sheet rock, floor is bamboo. Working space is approximately 7' (between speakers) and 8' (from the speakers to seating). Seating and speakers are placed on the 2 painted sheet rock walls. I am not interested in high volume.

I have been advised that I should be looking for a subwoofer that is capable of 500W peak power handling. My preference is used.

Not many prebuilt passive subs these days, unless you are able to go DIY. When you say "open to another space" you need to factor that in space wise. Is that total space a lot larger than the 14x14? The additional space may benefit you a bit, because 14'x14' enclosed would be a bad scenario; square rooms are your enemy for bass and require different considerations.

Most of the ones I see are In-wall variants, and the others are either super cheap or very expensive. Peak power handling isn't something you can figure until you know what the sub is, because that won't be as much a factor in determining the sub really.
