IF receiver on the PSW-I225 and other questions

[calivette2003]

I recently bought the I225 and was very pleased with the ease of setup. No wires to route through walls and ease of placement, can be repositioned in two minutes without having to go back and re-route wires, spackle wall holes etc.
Q1. The performance is surprising considering it's a 8" woofer and I previously had a 12" Sub. The porting design works great but I believe the design of having both the woofer and port firing downward makes the difference. So the question is how do the forward firing woofers, non boxed in the floor, or in the wall work if they have no floor to bounce off of? I thought what re-enforces the base is the fact the sub fires directly down onto my hard wood floors and adjacent wall which also redirects (bounces) the bass along the floor and all over room. If a woofer fires into the air (in the case of forward firing, floor or wall mount) then the bass should be thinned out as it transmits through the expance of the room's air.
Q2. I have looked all around the I225 box for a IR receiver window. If the receiver is inside the box isn't the signal "drowned out" passing through all that wood and metal? Where is the receiver and how does it work?

P.S. When the sub arrived it has a Polk Audio advertisement for the below floor units which I had previuosly wanted (no speaker to take up space)but choose not to becuase it has no floor to bounce off of.

Bass is omnidirectional and travels in all directions. Floor loading(down firing) as well as back an corner loading can increase output, but can also exaggerate bass output, and make it become boomy. The little i225 is very well behaved and has decent output for it's size. Ideally you don't want the sound bouncing off of walls an such. Properly set up in wall subs can pressurize a room well, as well as an IB, with the IB usually being able to dig lower, but not handle quite the amount of power. No being able to have a floor to bounce off of should not be a consideration. The receiver and transmitter as RF(radio frequency) like your tuner, or TV. RF can pass through walls, think rabbit ears on a TV picking up signal from out side of your house. The antennas are internal as they do not have a long distance to travel. Enjoy your sub.

i had that same ad on mine when it showed up. that floor unit looks sick, but $$$$
