Below 20 HZ Notes/Instruments

I tried my strata in the corner and it sounded absolutely terrible. It's now sat just in front and to the left of the right hand speaker ... nearly in the middle of the room, with the volume turned up much louder ... and it sounds tremendous. Corner loading was certainly efficient (read loud) but very boomy and resonant. I have read that the REL crossover is not a steep slope, and so it will still produce output significantly above the xover frequency. So if your mains already go down to near 20Hz it may not work. However my mains (Spica angelus) are rather bass shy below 40Hz so it works just fine for me (crossed at 28Hz).

I have stereo rel subs like suggested by Nilthepill and if it is finicially possible for you I would recommend it. Stereo subs are amazing and it has benefits like clearer and deeper soundstage. Better seperation and of course a ton more bass. I was amazed on how much it cleaned my sound stage up.

Seandtaylor. You could be right. The dealer that sold me the Rel, who has never steared me wrong, told me not to put it in the corner and to put it exactly where you have yours. Sumiko claims that Rel is designed not to sound boomy in the corner. I also have a different model but Im not sure if that makes a difference.

I did find that it was clearer in the corner but maybe that has something to do with the room too. Im not sure.

I know you just cant throw it in the corner and you have to try different distances and even try turing the Rel the other way. Sumiko told me to put the Rel tight in the corner and with a continous 20 hz signal back it out an inch at a time until it gets clear and then when it just starts to get boomy again back it up an inch.

I was persuing the Dunlavy Tower subwoofers option futhermore. ( They have info on their web site- spec and description summary and some owner systems). The description mostly talk about the bass notes that can be heard from the movies. The built in cross-over 20-100 Hz tuned similar to the V's and that the DTS's should be placed right next to the V's. No mention of music! I am skeptical about musical merit of this arrangement. Of course I will have to call them tommorow to find out more. If this works, man that would be one heck of a stereo!!!

Even if you cross over at 21 Hz you will still tend to blurr the imact of the SC-V's on music. The ears sensitivity increases enormously as the tone goes from 21 to 42 to 63 to 84 based on the Fletche Munson curves. This effect will be magnified by half wave length standing wave room modes.

You didn't say what kind of room treatment and placement you have but it also takes very careful placement to not just load the room. I used a RTA to first position the speakers and then the Sigtech to align them for very smooth low bass. You can easily ear the difference on good organ and electronica recordings.

If you just want the explosions to jolt your house, these niceties don't really matter
