View Full Version : reducing localization of bass from sub
01-06-2003, 01:43 PM
My sony 50 watt sub with an 8-inch cone is currently behind a chair that is next to the right side wall in my HT room near the front. I can't put it next to my front speakers because of lack of space. Yesterday I was watching "XXX" with vin diesel, a movie with lots of bass, and noticed that I could very easily tell where the bass was coming from. (Also, it sounded like the sub was having a heart attack, but that was probably from cranking it up too much. In the future I think I may get a larger sub, because I originally purchased it for my much smaller bedroom, where it worked just fine. ) Anyways, does anyone have any ideas on how to make the location of the sub less obvious? Thanks for your help.

Never mind Gonzo. I found it in the flea market forum. A 12 is just too big for me (that's what she said):p
A like a firm low end, I have an 8" now, and flip flop all the time on going to a 10", but the 12 would be too much for me. Good luck.

ronaldo, 50watt 8incher that is mostly your problem. Doesnt drive loud or deep enough. That is what you are strugling with.
Best advice is to put it in the nearest corner to the TV. You will get more bass and less localization. Also lower the freq. if possable.
but the 12 would be too much for me.
Sorry about that Zen, give it some time. Once u have one u don't have to use it all the way - just a little at a time until you get used to it.;)

Agree with Scott - crossover frequency is probably too high.
Also, if the sub sounds like it is "having a heart attack", it is most likely producing vast amounts of 2nd and 3rd order harmonic distortion, which is easily heard and localized because it occurs at multiples of the source material frequencies.
BTW, there is nothing inherently slow or overly powerful about a 12" driver in a sub. Properly calibrated, it will blend seamlessly into your system, dig much deeper, play with much less distortion, and will not be easily localized. I highly recommend you strongly consider Ganzo's offer on his Velo.

thanks for your help guys. I will tinker with the sub a bit more this weekend and come back if the problem doesn't go away.

Agreed with above, 18" properly calibrated would not be too much. Turn the xover down on the sub, set your mains to large (if they can do it), and place the sub between your mains.
With those corrections, the sub should blend *better*, disappear a little more, if you will (assuming the sub isn't being over-driven).
Ps, what ARE you running for the rest of your rig?

my ring includes: Fronts: Wharfedale emerald 97s, Center: Polk CS 40, Surrounds: Wharfedale diamond 7, Denon AVR 1803, Panasonic 47 inch widescreen. In other rooms there are: a pair of Monitor 7s, Monitor 10s, Snell K-IIIs, and RTi 28. Originally the RTi's were my surrounds but then I moved them to the dining room. And I know that it's important for the front soundstage to be timber-matched, but it sounds fine to me so far, so I'm not going to bother with it.
