Onkyo HTIB Subwoofer?

[bigbirt]

Okay, so I bought the HTS-780 a couple of years ago and I have never been too impressed with the subwoofer output when the action really gets going in movies or when playing music at or near half volume. The sub just sounds like it can't keep up with the audio.
I just bought my first HDTV (Samsung 50" plasma), Blu-Ray DVD and with the HTS-780 I am seriously not happy with the sound. So I ordered the Onkyo TX-SR606 (have not received it yet) reciever to replace the standard HTS-780's...but I am worried that the sub will still be a weak link.
So my question is: does anyone know if this popping is due to a weak amplifier built into the sub or if it is an inexpensive speaker in use??
I have a set of Infinity Kappa perfect 10.1 subs. I know that they are 4ohm, but if in fact Onkyo used a quality amplifier and cheap woofer would I be able to install one of them in the onkyo subwoofer enclosure?

The Kappa Perfect woofers are of 1st rate quality, at any price. However, to get the sound quality, they need some very specific cabinets built for them; you can't just throw them in any old cabinet and expect good results. In addition, for HT use especially, you should have a clean absolute minimum 250-300 watts RMS to each driver. Ideally, 500-600 watts. If you can cut wood, I would recommend you go for your first DIY project and build a couple of matching sub cabinets(one for each Kappa Perfect). I can help you with the appropriate cabinet design to get the most performance out of the drivers. If you build to my specification, and use an appropriate power amplifier, your subs would match the measurable output and distortion/compression(sound quality) of commercial units costing thousands of dollars. I kid you not.

Thanks for the reply. I am a big DIY...and I have some know how with wood working. What would you suggest as far as building the sub boxes for the home??
