Ok, so here is my update. I received my 2 RW12-D subs yesterday. The boxes both had slight damage (see the pic) but the subs themselves were perfect with no damage. Both subs had disconnected ports. I think it was warehouse forklift tines that did this, not UPS.
Today, I fixed the first one. I removed the amplifier panel and used some standard duct tape. I put several pieces around the inside of where the port mounts (I don't have a hot glue gun) and then re-inserted the port tube. I then used several more pieces around the outside of the port tube/port junction. It is now nice and solid in place. I can glue it later if I need to, but I think it will be fine. I just had to test it out!
So I pulled my HSU-STF2 sub. Here is a comparison shot of the 2 side by side
I used the same single LFE connection to the RIGHT RCA input. Seemed to work fine. I plugged it in and powered it up. Everything looked good. LCD screen was fine and the proper power cord was in the box.
I set the sub to DEPTH, 0db on the volume, set the crossover to 80hz and left the rest. I think put in the HD-DVD of Transformers just for a quick test run.
I have to say that the Infinity is different than the HSU. The HSU output is tight and very controlled. The soundstage is narrower. The Klipsch output is much broader. You can really feel it and it does a great job of filling in the lower end. I think it is sloppier than the HSU, but I only had about 30 minutes to goof with it before I needed to get my son at school so I will have to play with it more to get a better idea. It is in the exact spot as the HSU (8 inches from the back was and about 2 feet from the side wall).
Here are the stats of my system currently.
Front Left/Right - Paradigm Titan V2
Center - Paradigm CC270 Center V2
Rear - Paradigm Atom V2
AMP - Marantz SR5002
Toshiba HD-DVD XA2
I bought the 2 of them for my new dedicated theater room build I will be doing over the next 8 months or so (while doing other parts of the house at the same time). My gut is telling me that 2 might be too much for my room.
My Marantz is a great little receiver, but does not have the benefit of Audyssey for correcting, nor did I do a bunch of setup with an SPL meter etc. It is just setup with my Video Essentials and my ears. I think that it will make a great sub once I get it tuned.
I might return the other on after I play with this one tomorrow. See if I can get it set just right. I can say that there is a noticeable difference between FLAT, PUNCH and DEPTH. I think PUNCH might be the best choice if you like your base tight. But again, without really digging in, it is very subjective at this point. My room is quite large with the theater being a 12x25 section of a 35x25 family room. The new theater will be about 15x22 with acoustical treatments, riser etc along with base traps, so that will make a difference. I will most likely just keep the other one just in case.
I will report more tomorrow.
