Subwoofer placement help needed please!

post #1 of 13
Thread Starter 
I have read umpteen articles regarding sub placement and what I get out of having read all of the viewpoints is that this is a VERY subjective matter. I will be getting my new sound system in about 1 week or so...and I really only have 2 options as far as placement. The place in which I have my current crappy HTIB sub is the ideal place given my room set up...but now after having read everything on the web about 'ideal placement' I am wondering if placing it in the corner where I had planned will ultimately cause to much bloated/delayed/un-even bass response + sound. The sub I am getting is the Aperion Bravus 10D, it is 500 watts and so should be adequate for my listening environment which is quite small. My issue is that I am not merely facing corner loading my sub, and not even tri-corner loading...but something more along the lines of quad-corner loading based on the walls and couch that will surround it!! Does anyone have any idea as to whether this will adversely impact the acoustic integrity of the sub...or will setting for proper crossover, level and LPF help to mitigate any un-wanted sound effects that may otherwise be induced by the configuration I will be employing? I have attached some pics below of my listening space, and where the sub will be located...any helpful advice or commentary would be greatly appreciated!
The third pic below is really my only other option (to the right of the baseboard heater) aside from the 'corner sandwich' as shown in the second pic. Not sure if this would be a better option...I intend to try both locations but any advice about what will likely yield a better result is welcome...

I have no idea what this means, can you elaborate please?

No offense, but a sub that small needs all the help it can get. The last thing you'd want to do is not to corner load it. cool.gif

No offense taken.
The sub you see in the picture is my old sub...as noted in my original post, I have purchased a 10" sub from Aperion.

That's still too small to deliver high output, let alone pressurize a room. Unless you can verify by measurement or the sub crawl that it works better elsewhere I'd leave it in the corner.

Yes understood...my viewing area is quite small, I would say the room in total is no more than 275 sq.ft. Regardless, eventually when I move to a bigger house I plan to add another 10" to the mix to add some low fequency 'umph', but for now the one 10" is all I have to work with. Do you think the fact that I have the end of the couch near the corner will negatively impact LFE, or would this actually enhance the overall effect seeing as I only have a 10" sub? In essence I am 'trapping' it in the corner. That said, should I point the speaker in to the opening (across the front of the t.v), or would I be better served pointing it in to the wall, or end of my couch?

Mains volume is distance dependent, subs, not really. In the range they operate in impact is dependent on the output relative to the volume of the entire room. For a room the size you have I'd say at least two of the subs you have would be required for adequate room pressurization. In a significantly larger room, four. The direction the sub faces doesn't matter, its output is omni-directional.

Thanks Bill, the feedback is much appreciated. I guess my best bet is to set it up, see how it sounds and then tinker with the settings (level, crossover, distance from the wall etc.). Being that my room is not ideal for optimal sound reproduction, my goal is to simply achieve a 'passable' result...which would involve the bass not being too far down the line on either end of the spectrum (be it too boomy or too understated). I cannot afford another sub right now but I will keep your advice in mind and pull the trigger on another one when its feasible. My receiver is only .2 capable so running more than 2 subs really isn't an option for me.

A simple Y will take care of your .2 issue if you move forward.

You only need .1 to run any number of subs. In a huge room the independent BMS that some .2 and higher AVRs offer can be of some benefit, but for the most part the only necessary independent adjustment required of multiple identical subs is volume, which can be set on the sub amps.

+1.......I once ran four subs off .1 signal. Your y-cable is your best buddy wink.gif

Gotcha. To be honest though it is a moot point for me as my Marantz SR5008 has 2 LFE pre outs - which will be enough as I have no plans to do anything beyond a true 7.2 configuration. I am a videophile at heart, and while the audio portion of my arrangement is important - I am not striving for the ultimate audio experience - just one that gets the job done well, and is properly balanced / calibrated. I suppose that may change over time...but for now it is the way I look at it. I am rather new to the audio end of things...this is my first proper audio set up...have been using a Sony HTIB for a decade now. Terrible system really but I couldn't afford anything else at the time when I bought it. To be perfectly candid - I am finding the sheer amount of variables and audio adustments/configurations to be a little overwhelming...the Audyssey Multi EQ XT come with my Marantz SR5008...and I have been reading through the official Audyssey set up guide. I now have to run out and buy a tripod so I can run the damn thing and get good results...lol
My wallet already hates me...and my wife will too after a few weeks of my taking up refuge in the basement tweaking the living daylights out of my new system.
All the gear nowadays is wonderful in its own right - but I do miss the days of plug n' play...our parents had it easy - they bought stuff, brought it home - plugged it in and then enjoyed it. I feel like you need to be a master researcher and part-time calibrator now to enjoy optimal results from your home theater equipment. Though the end result if done correctly can be awesome...sometimes the road to said awesomeness is intimidating...and taxing.
