Subwoofer Inquiry

second, why if you dont mind me are you planning to get a second subwoofer? im sure the obvious why not answer will come up, but is it because you feel that your current sub is not providing the ample volume, is it not covering the entire room, or are you like most people, who want things in twos?

kidding aside, im curious about your room space tho too. you sure about that? hit us up with room dimensions, and if ever, a picture so we can gauge what may work well with your current setup.

lastly, to answer your inquiry, if i had no other variables (readriorities or responsibilities to answer to) i would consider selling the current subwoofer, and going with two identical subwoofers. at a cap of $1500 there are many options,

-the new SVS PB-1000 or SB-1000 for a grand, better yet get dual PB12-NSD's for a tad $38 dollars more.
- PSA has the XS-15 for $749.00 each,
- HSU has the VTF-3 MK4 available too starting at $699.00 each....

of course, your current sub, paired with another subwoofer is also an option, but may be a tad difficult to calibrate for them to work 'together' so to speak. it aint hard, but im not saying its easy either. besides, wont it bother you seeing two different looking colors and sizes?

best of luck on your quest, and if ever, you know where to find us.

what would you suggest for my basement room

20 x 12 x 7 one small 2 x 3 window back wall top center, one door, back side wall..

concrete floor with carpet.. 1 big sub or 2 smaller identicle subs

input would be great thanks

i like the svs cylinder subs fore easier movement im a bit handi capped in the legs. to get those sweet spots.. would like projection too so front
center placement is out..

maybe placing opposite middle side walls or opposite front and back corners..

thanks

Give SVS a call, they will tell you what will work best for what you are planning. HSU will to. Another company you might want to consider is Power Sound Audio?

with all due respect to nitro230 i have created a new thread for you.

its difficult to say because we can give room dimensions all day, but dont know how the room would interact with the subwoofers per se. the cylinder subs are great as a pair, but im not certain if they would work for you if you consider front projection as your ideal setup.

given the fact that we also dont know if its going to be a dedicated closed space, if its a living room with an open floor area etc.

with the dimensions you have tho, two subs would definitely cover a good general even area. one sub can probably give you a good amount of output, but not as smooth as two would so to speak.

2 Subs would be my advice also - Easier to balance out the low-end throughout the room.

Rythmik has a new rear ported 12" sub for $549 or $1098 for a pair. They have a solid reputation as do SVS, HSU and PSA. http://www.rythmikaudio.com/LV12R.html

Since bass is so particular meaning you literally have to catch its wave, put the sub in the place you normally sit and watch movies the most, move whatever you have to, to get the sub in your listening area.

Then, go to the area where you think you want to place the sub. Play LFE scenes or tones through the sub (that is now in the place you sit).

Now go move around the area where you want to place sub and find the spot where the bass is most responsive. That is your sweet spot. Now logic dictates that if you put the sub back where you found the sweet spot, when you sit where the sub WAS, then the sweet spot will be there.

Repeat (without other sub on) for other sub placement. You can configure for a guests sweet spot or double the one.


This worked great for me when I changed subwoofers.

Good luck and if you have cement floors you'll ned risers.

This thread will help shed some light on risers. I chose to go the DIY route as there weren't any being made that my Velodyne would fit on properly.

how are your risers working out for you?

seems like a good idea from big daddy eh..

why didnt you build your risers higher tho? did you read about the 25% rule
at the end of the theory part?

did you put any rubber isolators on the bottom of your risers?

sure would like to find some good info on how to acoustically treat a concrete floor in a HT basement room..

thanks and cheers

In my gallery I have pictures and descriptions of the build. It raised my sub a total of 6". The rear port is on the lower right side, when I had it on my carpet, it was slightly boomy sounding and the carpet absorbed some of the frequency. It doesn't have any feet on the bottom, it has two sheets of 3/4" MDF and 4 pieces of a 2x4 in the center. I filled it with spray foam insulation and poly fill and covered it in black automotive carpeting. The bass became tighter, and gained a little more impact in the process. When I watch movies or listen to music everything sounds like it's coming from the front of my system and blends in nicely with my Ascend's.

great to hear it improved your sounds.. after reading big daddys post
i was thinking of making a riser 18 inches high.. maybe the bass would be even tighter and punchier sounding getting it into the verticle and horizontal planes eh..

i saw big daddy using rubber isolators as well,, and a great use of your hockey pucks in the summer time.. when winter rolls around and u lose your
pucks in the snow you always know where you can get one eh!

whats the foam do in the riser? i didnt see foam from big daddy..
think when i build some i will using roxul sound insulation ( mineral wool)
with some rubber isolators off the floor.. rubber is an excellent isolator..

thanks

thanks for motivating me .. I just made my 1st sub riser today wanted to check it out.. i just use my collection of scrap stuff..

2 10 x 2 18 inches

2 1/2 plywood 18 x 18

3 roxul afb acoustic fire bat cut to fit.. 3 x 15 x 18

drywall screw and glued the ply to the 2x10 which where 9 inches really
so 3 layers of the abf fit perfectly.. left the 2 end open and wrap and staple so black fabric around the whole thing..

wow really improved the bass out of the sub can turn it up about 3 db louder..

cheers..
