[QUOTE="seanjammy, post: 1096985, member: 17457"] Qts of 0.27 is not going to work well sealed. Aside from the box size you need, you will need a monstrous amp. Use a vented enclosure, tuned at Fs or slightly higher, will give you your best first guess results. As for your overall objectives of running a HP on your main speakers to achieve higher overall spl levels, in my experience you will lose resolution through the processor. Further, using subs to augment LF for 2 channel has been something that I have experimented with a lot, with massively varying degrees of success. My personally held view is that best results use low spl, small motor woofers which are light. Finally, the amplification you run on the woofer is a huge determinant factor. Big power can ameliorate a lot of the issues described above, along with some DSP, if you have the budget and ingenuity to design as such. [/QUOTE]
