Axiom Home Page Forums General Discussion Home Theater Oops.

I just discovered that my couch is in a bass null. Guess that subwoofer placement does matter, doesn't it?

Just move your house around a bit. Easy.

I need to work on my sub placement as well. I notice as I leave the room towards our front entry way to the house, the low bass seems to be much more emphasized in that location. I don't notice it as much when I'm actually in the room.

Yeah, I'm not sure exactly what it is, but when I get a few feet closer in the direction of the sub, it sounds much more full. Maybe our resident room/sub expert will hop in here... John... I promise I'll try to read everything you say instead of glazing over!

my bass is located in a closet. if you want to see i can show you a picture

Willso7, aren't you sacrificing quality of Sub sound by enclosing the sub in a closet? Alan, from Axiom and others have mentioned many times that subs should normally not be enclosed in anything.

My bass is also kept in a closet. I keep it in it's case though with its strap and a spare cable.

Sir Quack,

Yeah, I have a long narrow bathroom, and if I leave the door to the foyer open, which opens to the living room, the deep bass from the EP500 is spectacular anywhere in the bathroom. It's obviously a standing wave, which may boost the bass at some frequencies by 10 to 20 dB, but I also think that the dimensions of the bathroom somehow "load" or tune the frequency making it seem more powerful.

I used to believe that you had to be the full wavelength distant from a subwoofer to hear ultra-low frequencies, which would mean 30 feet or more for really low stuff, but, as it turns out, that's not true, because a good car subwoofer will pressurize the relatively tiny car interior (as long as you keep the windows closed), making frequencies at 20 Hz and deeper audible.

It's always a compromise with furniture layout, listener location and subwoofer placement, unless you have the funds and the space for four subwoofers, or even two subs. (My old mentor, Dr. Floyd E. Toole, found that four subwoofers produced the most even distribution of deep bass for a variety of listening locations in a typical living room.)

Regards,

It's time to throw your bass a coming out party.

Alan just put quotation marks around the word "load" while talking about the "bass" in his bathroom...classic stuff, really.

Capn,

Ha, ha. Someday I'll do a search for all the scatalogical references on these message boards. There is a grade-school-humor part of me that I can't resist at times. Perhaps it is because my formative years were in the repressive 1950s.

Of course it was you who pointed out my reference to "load" in the context of the bathroom!!

Regards,

Scatalogical. I learn not only about home theater on these boards, but my vocabulary improves as well! I'm sure that word will come in handy, especially because of the predilection of some of my co-workers.

Alan,

With regards to your car stereo analogy, what you typed seems most logical, but hasn't always seemed to be the case with what I've noticed in practice. I've never really thought about why it happens, but I distincly remember cracking the front windows just a few inches and listening to the bass become much more full and natural sounding. It would appear to go deeper and with less effort. I've noticed this in different cars with different systems.

Is it because there is too much pressure in front of the woofer cones? Is it because the waves can escape before there are too many wave reflections that could cause cancellation (this is blatant speculation on my behalf and very well may make no sense whatsoever)?

I have a 1999 Dodge Intrepid right now that I replaced the stock speakers with Polk Momo coaxials, and I replaced the factory deck with a Pioneer model (that I love). I put in a significant boost at 40 Hz and can notice what I'm talking about even without a subwoofer.

Any ideas anyone?
