Is the rms 450 watts or the peak output?I want to know the rms of the sub

Specs say "450 Watts RMS built-in Class “A/B” amplifier". Unfortunately there is nothing in the documentation that mentions peak output. This thing is surprisingly loud for its size.

Does this sub come with a grill to cover the front?

Yes it comes with grills for front and back speaker. I have 2 of these subs and they are great!!!

What would you recommend this subwoofer or a klipsh i already have a klipsh towers and large center, but have an onkyo woofer

I have always used Earthquake subwoofers for 3 different setup I have in my home. Earthquake uses SAPS technology which gives heavy bass and is great for action movies. This is powered sub with input and output so you can connect another sub if you need bass to be coming out fro another source.

is this dual driver sub

Hi You can look the specifications up on the internet but no, there is one active and one passive driver.
