    Hey guys, I'm new here, and i have a question. I have a Sony SA-WX700(really impressed by this one), and I need to figure out a way to get this thing crossed over to like 30hz, what kind of crossover will do this?? This thing goes very deep, but my main speakers go deep enough, and I just want this for the subsonic levels, my main speakers are Mirage M-3si 30-33,000hz +-2db. Thanks.

    I wouldnt cross the sub that low. Leaving your fronts playing that low will eat power and unless your fronts have a dedicated sub the extra low frequencies will take away from your midbass/midrange area.

    I would cross in the 40-50hz range.

    Welcome to the HTF,

    I agree with Andrew, set it around 50 Hz. You could build a low pass crossover but it probably isn't worth it.

    This is for music only guys, sorry i forgot to mention it earlier. I know that a hometheater setup won't work as good for music. Any ideas??

    I would double my emphasis on this for music. Music has a lot more subbass. If you let your mains play this it will stress them a lot. Not to say it couldnt be done but it will be easier and sound a lot better with your sub crossed higher.

    What are you driving these speakers with? Does it not have a built in x-over? The sub has a built in X-over as well, i'd just set it to it's lowest point and adjust the gain to taste. This sub is probably adding a lot of oomph, but in reality, likely does not truly reach down to 20Hz with authority. Sony does not list the -3dB for the sub, so there is no way of knowing from the specs, just a guess, meaning if you filtered it at 30Hz, you probably aren't going to get much out of it.

    You need something that can go to 20 clean, with extension below that. SVS PB2 or 20-39, HSU VTF-3 or TN1220, DIY.

    Yes, if you are open to DIY, then a Sono/tempest is going to get you the most bang for your buck. A friend has one tuned to 17Hz [​IMG] It reaches well into single digits. The 20-39 will already go very low, and the 16-46 will obviously go lower, if that's what you are looking for. Even the 25-31 is extremely impressive in volume and depth. The larger cylinders are not to my liking though, visually anyway [​IMG]

    Well, there is just something about a sub that does wonders to the soundstage, even though if its just playing the really low frequencies, it adds life to any speaker system if done right. I just wanted to add something for the really low frequency, sort of like how a REL subwoofer aids in the subsonic levels, where they are crossable to like 22hz, if you understand what i'm saying. Will a boxed Tempest be able to reach into the single digits as well? Thanks.

    I can't answer that, but if you ask in the DIY area, someone can probably help you with specs for a box for the tempest that will reach single digits (or close).

    From what I have read CDs do not contain any information below 20hz. Maybe someone else can confirm/deny this.
