Are there any good downfiring passive subs to consider?
Currently looking a building a PE 15 Ultimax kit paired with the B side of a Behringer NX6000D to round out the lower end of a pair of front facing 10's powered of the A side of the amp. It would sit behind a pair of reclining seats in a high traffic area out of sight with little ones. Frankly, I don't ever want to buy a sub with an integrated amp again with cheap flexible DSP power available. That said, I don't see many options out there that are not DIY projects.
