SVS sound path

Two PB-3000 incoming. Home with tile floors and no neighbors that are closer than 100 feet away

Soundpath or no?

try'um, don't like them send them back. I like them on my 2 SVS subs on a suspended wood with carpet floor.

Soundpath or no?
Depending of your floor.
If on a hard wood floor, they should help by decoupling the sub from the floor.
If on a carpet over a hard wood floor, not so much or help a little. Only trying them would tell if they work for you, SVS do have very generous return polices.
That said if the subs are on carpet over a concrete floor. There should be no difference at all other than a look thing, that you want to achieve.

I once got some fancy outrigger for my main speakers, and the center speaker stand.
https://soundocity.com/product/outri...h-brass-cones/
Not that they needed, since my speakers are a heavy carpet over a concrete floor,
Just a look thing, and to make-it worst. Change my mind about the finish, and re-order a set of three with dual finish color
The Chimaera theater
Page 1, post 2 ant the picture #9 show the dual finish nicely.

Tile floor? Forget it.
Wood floor and creaking? The soundpath will help.

That said, neither would the soundpath eliminate rattling with your ceiling, doors, windows or those kind of stuff.

If the flooring is tiling over a concrete slab - that flooring system will not absorb/transmit mechanical energy - so the stock OE feet will be fine.

If the flooring system is wooden plywood/rafters over an open space (like a basement), the SoundPath Subwoofer Isolation System will definitely cut-down on transmitted mechanical energy - which in-turn reduces floor boom and buzz/rattle.

There will always be some buzz/rattle result from the acoustic sound pressure of the subwoofer - and the Isolation feet will not help with that. Any SPL related buzz/rattle needs to be treated at that location using Blu-tack or similar products.

Set the subs to -10 volume and run Accu-EQ. Report back with bass management results for each channel and the subwoofer, along with the subwoofer channel level.

Also provide the brand/model loudspeaker at each channel.

Hi Ed, not to disagree with you on your own products, but I can attest to the Soundpath feet minimizing the rattling throughout the house with my dual PC-12 Plusses. I had stuff shaking all over my master bedroom which is on the other side of the the subs. After installing the Soundpath, it quieted everything down and did make a noticeable difference.

Ed stands correct and I like to add that he is a very honest guy!! I also called to purchase the feet and he told me not to spend the money on them since I was sitting on concrete and it would not make a difference. Now upstairs I am sitting on a wood floor and the difference is noticeable. Thanks again Ed

You're very welcome!

DJ_JonnyV may have simply misunderstood my post above. If he's on a wooden floor over an open space - the SoundPath Subwoofer Isolation System will definitely help. If he's on a concrete slab - they are not needed because concrete doesn't transmit mechanical energy in the subwoofer bandwidth. Regardless of the flooring application, there will always be an acoustic component to buzz/rattle which the feet obviously will not change. For acoustic buzz/rattle - attack it at the buzz/rattle point.

Apologies for the delay in response as late evening is the only time I can really check the site. This is on carpet over a wooden sub-frame with a basement underneath. The PC-12+'s are on one side of the wall separating the bedroom from family room. As soon as I put these on them, stuff quit rattling as much in my master bedroom. Definitely worth the investment for me. Heck, even have them on the SB12NSD in the master bedroom.

The wooden flooring over an open space (like a basement) is the primary target application for the SoundPath Subwoofer Isolation System and you will definitely experience a reduction in buzz/rattle and floor boom.

The fronts should not come back at 200 Hz for that model speaker - it has three 6.5" woofers with rated extension to 26 Hz (no dB limit specified).

That speaker should come back at full-band or 40 Hz.

A crossover of 200 Hz for that speaker very likely suggests a bad/defective set-up microphone.

What is the subwoofer channel level in the Onkyo after Accu-EQ ran? (this was with the subwoofer volume set to -10 at the subwoofer).

It keeps setting it to 200. I went in and selected full band again but each time it goes to 200hz.

The subs were set at -10 on the app and the onkyo has them at -2.5 after the EQ

Weird

I would contact Onkyo for support on why the fronts are coming back at 200 Hz. I suspect it's a bad/defective set-up mic, because that speaker clearly has decent bass extension.

I would go with 60 Hz considering the subwoofer in your system. If you select 40 Hz, the subwoofer will get very little content on most music.

A bad mic will also result in a very wonky/bizarre FR from the loudspeaker channels and the subwoofer channel - and also the subwoofer calibration level will be too loud.

I'm not saying that is the case definitively with your set-up - only that very high crossovers which are inconsistent with the actual bass capabilities of that speaker are certainly a warning sign worth looking into.

very much appreciate the help.

When I change it to 60 it sets the speakers to small. Is this ok?
Also, the LPF of LFE is set at 120hz. Seem right?
Center is 100hz

Also, for the app. should I change it to movies for a the preset?

If the Onkyo has Audyssey - it will still use large/small and yes - small is appropriate for any channel which has a crossover assigned.

Newer Onkyo AVRs with Accu-EQ simply use the terms full-band or state the assigned crossover and don't state speaker size as large/small (at least not to my knowledge).

Yes the LPF/LFE should be set to 120 Hz and is typically the upper limit used by the mixing engineers for the LFE .1 channel.

Ed, do you recommend any of the presets like Movies on the app once you have run the EQ?

Movies preset has no EQ (from the factory). Default volume is -10.

Music preset has a mid-bass bump (from the factory). Default volume is -10.

These are just place holders - you can override the factory preset and change it to anything you want.

I personally don't use any PEQs for movies.

HI Ed. I went out and got an RZ830 as I am planning to add 3 sets of Prime Elevation so needed the extra channels.

I reran the calibration and much better results. It put the mains at 40hz and LFE the same at 120hz.

Cant wait to get my primes all set up and appreciate all the help.

This is much better - an expected crossover for that speaker. 200 Hz definitely indicated a problem with the previous mic/AVR.

Where did is set the crossovers for the other channels?

right now all is have is LCR and the two subs. Center was set to 100hz which I may teak as dialogue seemed a bit low. Should I set the center back towards the tv or bring it out even with the mains?

I am also considering buying a pair of SVS mains as well and possibly a center to have a full matching set.

Generally, I recommend pulling the center channel forward to avoid diffraction from the shelf or cabinet it's mounted on/in.

Here's some simple instruction of how to properly install a Center Speaker for the OP @toomanytvstosee;

-First, go get yourself a cheap laserpointer, a flat one if possible.
-Then put-it on top of one of your main (does not matter which one, since they are both the same height).
-Point at your listening area.
-Put a piece of tape to mark the position.
-measure with a ruler the distance from the top of the speaker to the center of the tweeter.
-Go back to your piece of tape at your listening area and subtract thatdistance going down.
-Put a new piece of tape and remove the first one.
-Now do the same for the center speaker with a little difference.
-First measure the distance from the top of the center speaker to the center of the tweeter.
-Go back to your main listening area.
-Remember piece of tape #2
-now take the distance from the top of your center to the center of tweeter and go up from the piece of tape #2 to that distance.
-put piece of tape #3 , and piece of tape #2 can be remove if you like, since it was the distance of your main tweeter.
-put the laser pointer on top of your center
-adjust angle until the light hit that piece of tape (#3 ).
Now you're done, all tweeters should hit the main listening position at the same height(for the main listening position)."
Also, Make sure your center speaker is sticking out of the cabinet by about an inch.
Sound reflection from the edge of a cabinet can play havoc on your sound.
