^^^ Absolutly, it depends on how much your going to spend.
The intergrated tube Subwoffer systems are cheaper; however, You'll gain so much more with a box setup in areas of better sound, running a bigger SUB and room to grow your syetem in the long run. The down side to boxs (especially if your going the Bandpass, ported box or huge SUB in a sealed box setup) is the loss of trunk space and the pain of routing/packaging all the equipment neatly (with the wires all being stealth). IMO i like the sealed box setup. It has the nice extended lows verses the bandpass or ported where all the sound is tuned by the port design of the box (at a EQd like setting). Good Luck Bro.
