Looking for subwoofer/s for this room. 50/50 H/T /music. Mains are Athena F2s , Surrounds are ARX A1Bs Center is Athena AS C1-1 and AVR is Yamaha RX-830 if it makes any difference. Speakers were purchased from recommendations from members on this board and i have been happy with them. Now looking for some subwoofer/s , open to suggestions and placement, dont know if 1 large or 2 smaller ones would be better.

Max budget $1300 including shipping
not opposed to B stock
considering 2 Rythmik LV12R or
1 Rythmik FV15HP
other suggestions welcome:)

Blocks A,B,C,D&E are my possible locations for sub

I think 2 LV12R's will work good for that size room. I guess it all depends on how much output your looking for? Are you a extreme bassaholic? The LV12R's should get you into the reference level range.

I like locations D & E for sub placement.

I like the dual Rythmik LV12Rs idea myself, although the 15" did very well in Audioholics subwoofer faceoff not too long ago. HSU, SVS, and PSA are also worth a look.

I'd go with the dual LV12R's from your choices. I would either do locations D&E for dual near field placement OR B&E for opposite corner loading. D&E might give best sound and feel at MLP BUT B&E may pressurize the room more evenly.

On location D would you face the driver towards the wall or the hallway? And on location E would the LV12 be able to be positioned as down firing with port up? How far of a distance need to be maintained from wall to rear port?

Thanks, Dennis

OP, since you're eyeing an FV15HP ($1,274 + shipping), I'll assume that dual PSA XV15s ($1,518.10, shipped) aren't too far off the budget cap mark. smile.gif

Given the sub's size (17" wide x 22" deep), location E is most likely out of the running. To avoid blocking the sub's rear-facing ports, the subs should be moved a bit away from the wall, so location A might also be out of the running as a sub placed there might interfere with pedestrian traffic.

So, I would try locations B, C and D and go with the ones that work best for you. smile.gif

Without room measurements, nobody can say anything with certainty. If going with a single FV15HP, it would be advised to buy the subwoofer, obtain room measuring capability and after integrating the subwoofer into the room's acoustics, with accompanying measurement graphs in hand, then decide how many more subwoofers you'll need.

Not out of the question, id just have to save a little bit more. If it is what I need I would rather cry once and be happy than cry twice and be miserable. The FV15HP is currently $1274 shipped.

Could measurements be taken before purchase by using current sub although not a good one onkyo SKW520?? I assume I would need a SPL meter and a frequency disk or could you use test tones on the receiver. How would you go about getting these measurements?

Thanks Dennis

Funny, I just added an FV15HP to cart and both "Texas" and "47 Continental States" show shipping charges. confused.gif

yea as eljay stated, dual xv15's would be a bump up in performance...they would pressurize that room nicely. Imo dual LV12 or dual xv15's are probably the 2 best bang for buck subs out right now.

You'll need to acquire a measuring microphone and a freeware copy of REW.

I would put the FV15HP in location "D".

Personally, you're better off, buying a single subwoofer, learning about subwoofer placement, get a sound meter to help with setting the subwoofer gain, learn about using your AVR's EQ program and then consider room measuring gear and a second or third subwoofer.

Yea but with all your seating areas I can gurantee you that one sub will not offer even bass coverage. you might as well start with a pair and possibly look at a third...something like 2 LV12's and 1 FV15HP. You can start with one, but expect only a couple seats to have a good response.

Just wanted to add if all your concerned about is one or two seating areas, then the FV15HP would be a great choice for a single sub as beeman suggested. This is a critical detail most leave out when sub shopping. More subs help smooth the bass response and coverage over the entire seating area, but again if your only concerned about one seating area, then a single should do fine.

And then again, phase alignment (nulls) of three subs can be a bear. The point being, there is no easy button.

while looking at data-bass CE2010 charts The FV15HP is about 6 DB higher across most frequencies vs a single PSA XV15. How much would 2 PSA XV15's close the gap to the FV15HP??

If i could get very close output to the FV15HP and even room pressure this may be a very good option.

Ive been doing too much reading my brain has gone to mush:eek:

. Is it correct that a 6 DB increase in output sounds double the volume to the human ear??

FV15HP $1412
PSA XV15 $1518

colocated they would slightly outperform the fv15hp from 16hz to 30hz and 40-63hz they would out perform by 3-4db. non colocated they would have slightly less in the lower region and similar midbass. This why I went with XV15's for a smoother response with similar output. dont forget to add 1.5db across the board for the xv15 data bass measurements due to how the mic was placed.

Been working a rate job and quite a bit of overtime so budget has been able to go up.

Option #1 2 Rythmik FV15HP locations A&D

Option #2 2 PSA XV15 location A&D and 1 SVS PC12/NSD cylinder location E

no sub room correction on Yammy RX-830 looking at mic UMM-6 or UMIK-1 from cross spectrum for REW and possible mini-dsp

Thoughts on options , mics and mini-DSP

Wow, go for option 1, option 2 does not compete. Option 1 will have a lot more output and be a lot easier to setup. It will probably have much higher sound quality as well. The most you could hope from option 2 is a bit better room smoothing, maybe, but it wouldn't be worth the trade-off for that kind of firepower.

Based on all the graphed situations I've looked at, rooms need that third subwoofer to bring the other two subwoofers together.

I'll opt for option #2.

Now if one were to order up a Rythmik, F25 and an E15, they'd have the three driver solution in a two subwoofer box but without room measuring capability, one will never know the truth of what's what with what regarding their room's acoustics.

Yea thats a good point bee, im almost set on adding a third myself, just so i can fill the entire room with bass +/-2db... even tho my seats are covered well. I dont like the pesky mid room drop of -8db. Its a small area about 2' x 8' dead smack in the middle.

Whatever your goals are, they are a great choice imo. If you go bonkers you can always ad a third. cool.gif
