So, verdict is in. ALWAYS go with two subs if you can. Played with different variations and placement of the 115sw and the 112sw. I've ended up with the 112sw behind the couch and the 115sw up front. The difference between the single 15" and two subs being used at once is staggering. Love being able to feel the couch shake with such clarity and encompassing bass. Thanks for all the assistance.

I hear this during movies and also with this test. The max was ~ 83dB measured about an inch from the front face. Thoughts? https://youtu.be/M5nfB-TDX3I

dB would depend on frequency as well, right? Lower frequencies would require more movement of the subwoofer cone in order to generate "x" volume. I'll play with the receiver settings (calibrated with Audyssey, gain set in the middle, XO at ~60Hz) and see if it makes a difference.

It's totally under warranty, the sub is less than 6 weeks old. I just don't have to pay for shipping (totally on principle)...

Honestly, when i first heard it i though it was the TV stand rattling, so relatively subtle, but noticeable. I would consider it a higher frequency sound. I got closer and noticed it sounded like it was behind the subwoofer cone. Moved the sub onto carpet to see if it was a base/hardwood issue. Same thing.

I'm hearing a rattle with the R112SW, calibrated the system with the Marantz 5010 using Audyssey, music, TV all sound great. I've noticed something that sounds like rattling (almost like something loose) coming from the R112SW behind the subwoofer cone only for really low frequency effects like a shuttle take off or an explosion. Some movies tested include Wall-E, Transformers, Mad Max. I'm wondering if i'm overdriving the sub the cone does move a lot but again not exceedingly loud volume? I can't imagine that i am, given that the whole system at seating position doesn't exceed 85db (Marantz volume is at 66-70). The sub will rattle using a test tone (Wall-E disc) has the GAIN at only at half or less and cross over at 60Hz the spl meter read 75db right in front of the sub. Plus, the R112SW spec sheet says if should be able to output 118db (not that i'm trying to get there) Any advice if i should try specific Hz or target db? I've never heard the rattle outside of movies. It's definitely not the subwoofer chuff i've read about from the port. Perhaps the R112SW wasn't the best idea for movie LFE....the R115SW is on it's way so i'll have to compare. I'll see if i can't post a video with sound... Edit: Video: https://youtu.be/M5nfB-TDX3I

I'll probably repost as a separate topic, but i'm glad i ordered the R115SW. I'm hearing a rattle with the R112SW, calibrated the system with the marantz 5010 using Audyssey, music, TV all sounds great. I've noticed something that sounds like rattling coming from the R112SW behind the subwoofer cone especially for really low frequency effects like a shuttle take off or a bomb explosion.

I can't imagine that i am given that the whole system at seating position doesn't exceed 85db (Marantz volume is at 66-70).

Thanks for the replies and the information. I think i will end up getting the second sub. Now just have to find a day off to receive the beast. Robo, the 250S are really nice, I have them sitting as the rears and the sound back there is really enveloping and diffuse. are they worth 848 for the pair, i don't know. I was considering them for the L/R surround, but then decided to save some money and get the 250F towers. Love the current setup and the 7.1 setup for music is amazing! I may end up swapping the side tower for the rear and see if it makes any difference, at some point, but i'd like to break the speakers in first.

MLP - middle listening point? FR/TR - functional/torsional resonance? Sorry new to these abbreviations, totally making stuff up at this point. XO i got Appreciate all the input thus far, 115SW is coming to fruition! any difference in sound quality of using the WA2 vs LFE subwoofer wire?

Hello all, I am currently running a 7.1 setup with RP-280F, 450C, 250F (surround L/R placed higher) and 250s rears with a R112SW. I watched Mad Max and Kingsman the last couple nights and absolutely was thrilled with the sound. The bass was amazing. Which got me thinking......could it be better!!?? The R112SW is doing great by itself, but I was wondering if adding the R115SW would be of any benefit. I was thinking of running crossovers on the 12 a little higher and perhaps putting the 15's crossover at its lowest setting - 40Hz for more earth shaking/tactile reasons. That versus getting a second 112SW Anyone running different sized subs and happy with it? Does the larger one drown out the smaller? Thanks for the help, the HT is only up and running less than a month so any assistance will be much appreciated!

Thanks for the recs. I ended up doing the RP-250F as the surrounds, placed on some old pioneer cabinet speakers so above ear level when sitting. For the receiver I'm really happy with the Marantz SR5010. I couldn't be more thrilled. I started with the opening sequence of "Dark Knight Rises" and went on to watching "The Martian". The audio from rear to front is seamless. For music, wow! Especially with all channels driven. talk about room filling sound

Thanks, appreciate the input thus far! any thoughts on surrounds? even thinking about replacing the existing bose towers with RP250F for side surrounds instead of the 250s/160m.

Hello community! Newbie here building my home theater system, have read through the forums and have assembled as follows: up front sits two RP280F, RP450C, and R112SW (more for musical taste and have neighbors). Current rear surround RP250S. Looking to expand the setup. As it stands, my bose 601 IV are my side surrounds. Pales in comparison to the rest of the system. So question is do I get another set up RP 250S for the L/R surround, or move the current 250S to side and place the 160M bookshelf speakers as rear surrounds? Room has high ceilings and is open in the back to the kitchen. Lastly, looking to upgrade receiver. While music will be primary, I do watch a lot of movies. That said, I'm not looking for any crazy setups...7.1 or 7.2 is probably where i'll max out. I'm not looking for power, just good clean audio with decent features. This is what I'm looking at: Denon AVRX4200W Marantz 5010, 7008, 7009 Onkyo TXNR838 Currently running on a Onkyo TX-SR606 for the last 8 years or so, have loved it thus far. Appreciate the help!
