While two 8" would be theoretically be better, a single 10" would be better for your wallet

Thank you sir jhnkvn!
I end up buying a used RE se12d2 with ported box. Ok naman sya puno ang jazz pagbumira hehe kaso almost puno din cargo area ko hehe. 11x28 ang nasakop. What if i use a rectangular 1cuft sealed enclosure para sa RE? Maganda pa rin kaya? Solved ako sa performance now but masimportante ung space eh. For the meantime inienjoy ko na rin ung medyo gapang na bass haha but i need a mono amp masusunog ung c160 amp ko underpower sir. Planning to buy used sound magus x or vs 1500 pagmaybudget na. Any inputs about this amp? Thanks po again.
T/S parameters of SE and the *** series are the same so you should check that series out for your enclosure recommendations (woofers). The *** is the direct successor of the wildly popular SE-series. I still scratch my head on why you went for a secondhand RE Audio though.. in general I dislike secondhand subwoofer drivers on the basis that most people abuse them heavily

Just get a 1 cu. ft. sealed enclosure. But if possible, stretch it a bit. What you want is to stretch the internal dimensions as much as possible while it's conforming to your size restrictions. For example, if you can still stretch it to a 1.4 cu.ft sealed, go for it.

Reason for this is that a bigger box lessens power handling because box = efficiency. If you needed 500W in a 1.0cu ft box to play a certain sound level, it'll probably need around 300W in a 1.5cu.ft box. I would recommend the best of both worlds, get the ported 1.5cuft box * 35hz. +3dB on the port is not a laughing matter especially if it's +3dB.
