Currently my HT system consists of (5) Infinity Primus 150 speakers and a DIY subwoofer I built some time ago in a 5.1 configuration. In order to satisfy my DIY bug and to also conserve some floor space I would like to build a Natalie P style small tower enclosure with a partitioned section for the subwoofer integrated into the bottom of the tower. I would basically take the Natalie P design and integrate it into a ~42-46" tall tower with a solid partition 22" from the top where the plate amp and the subwoofer would be housed. Would there be any drawbacks to doing something along these lines? It would be something similar to a Polk LSi15/25.
Also, I just bought a Denon AVR-590 to replace an older Yamaha receiver (wanted the HDMI and Audyssey EQ). It is rated at 110W @ 6-ohms. Would it be able to handle a Natalie P speaker setup without overheating? Another option would be to do the same with the TriTrix design that has an 8-ohm impedance should the Denon overheat.
I'd appreciate any advice that anyone could offer.
