Called SVS, we went thru AVR to make sure settings ok
the only change was LPF to LFE from 80hz where I had to increase to 120hz

they saying possible damage to amps? Both of them?? Seems nearly unthinkable but I guess its possible....


Going to take @Montucky suggestion and turn off one Sub

After PB13 Ultra's delivered on Monday, had to wait for my son to help when he got to house yesterday.



Finally, set them up and started to play with them. I had the HSU VTF2 MK5s. These subs do create some difficulty now in my configuration with the Emotiva T2 towers due to their size.

(See pics)

Before I could fit the HSU and EMotiva's in the corner, now I cant rather have to put the T2s in the front of cabinet



But, I am not seeing that big of a difference in sound vs. HSU's
. A little bit yes, but not dramatic enought for the $3K cost for duals. I'm going to play with them a little more but now I'm thinking about ordering the Monolith 15s while I have the SVS PB 13Ultra's here to do a head to head. Is there something I'm not doing right? My florida room also is a nightmare with all the glass but HSUs just seem to be more efficient.



I had the SVS volume at 0, and now calibrated to -10 but haven't played them since changing -10 as I will this weekend.

Also have all crossovers at 80, lpf>lfe at 80



Option 1, just return the SVS subs and keep the HSU's be happy with those subs as they do make the room less crowded and aesthetically more pleasing.

Option 2, order Monolith 15s do head to heard (little worried in Mono's not better now have to pay $300+ for shipping back)



I didnt want to spend more than 3K on subs because its not worth it with the little bit of HT usage per month....but I do want that awesome experience when I do.

Im not a big user of subs, maybe 4-6x per month for movies...that's about it.



I'm asking for any suggestions?? Help? Opinions....



Thanks





NOTE: Pics 1st is back of Florida room which is like 35-40 length, 14 feet wide

2nd pic- up closer to see configuration


There are a lot of things to look at here but if your receiver set the subs to -10 it’s very likely you will want them about 3-8 dB higher than that to have any fun at all.

For a room that size the smaller diameter woofers in the PB will not be able to produce that Thor’s hammer effect when explosions hit, monster footsteps etc depending on where your bass nulls are located.

Room placement makes a huge difference as well. Manual EQ can help smooth out the response and I generally find I do not like the way my subs sound letting Audyssey or other “auto” room correction algorithm EQ them.

Anyway for now I would suggest looking at JTR subs for your room. The 18” Captivator S1 are quite small for an 18” woofer”. Other great brands with very high performance are Seaton sound, Funk Audio and Power Sound Audio.

If space is your primary concern, dual JL Audio F113 are awesome but very pricey ($6,000 each?).

Welp, that didnt work either. 1 sub off still produces mediocre performance from the one sub on.

i may have missed it earlier but are you using RCA or XLR cables?

sounds like a pre-out voltage issue if your not hearing any output
I have some output, just not at a decent level, rather mediocre.

Try just one of the subs. Up the trim in your AVR to about -4db, go to youtube and play some of the bassotronic or bassmekanik stuff or even the EOT intro. Walk around the room to see if there is any difference. Maybe move that one sub into the middle of your front wall in front of your stand just for the heck of it.

If still no joy then return them. Too bad there are no PC13Us in the outlet. They would have fit in the same spot as your HSUs.

Maybe get another pair of the VTF2s and place them on top of your currents VTFs. You'd get a really nice overall gain above 20hz for just another $1200.

if all settings in avr correct...double check sub cable connections and/or try different inputs like lfe in or line input...otherwise I guess send em back....do the hsu subs still work?

Yes no probs with HSU subs. Prob hook those back up.

You can look at data-bass.com in the measurement section and compare response graphs of many, but not all subs. You will notice how well JTR perform. I think the Captivator S1 is $2,400 plus shipping.

That might be good idea. Go with 4 VTF2s. These VTF2s hardly used only like 2 mos total.

Did you try cranking the sub level in your receiver ? Are you sure you don’t have dynamic range reduction on or any other processing in your receiver that could tame the bass output?

@madhuski yes I have the right cable, input from sub pre out, to the left input on sub


Anyhow, its all done!! Something was wrong with both subs, they were outlet specials so who knows?? I literally just plugged in the HSU VTF2s, the whole room shaking and AC vent in ceiling next shaking.
I definitely should've heard that minimum with PB 13s

We packed up the PB13 Ultras, I'll call SVS tomorrow to pick up.

I've decided what I will do is get 2 more HSU VTF2s and stack them. This will actually work best because I can fit the towers and VTF2s in the corner and not have to worry about the Emotiva T2s placement.

This was a total pain in the ass, but I just want to thank everybody for trying to help me. Trust me it is greatly appreciated.

Sorry to hear nothing remedied the situation. Still think something wasn't set correctly. I believe those outlet PB13's were new stock close-outs. The chances of getting two of them that exhibited the same amp issue are probably slightly better odds than getting struck by lightning.

I’ve had a similar problem. When I got my first PSA V1500 the performance was incredibly underwhelming. My 20 year old 12” velodyne smoked it. For days I went through every setting there was, ran Audyssey a dozen times, moved the sub all over the room. It just wasn’t working properly. I got all the same advice you’re getting now like “your subs are canceling each other out”. Out of pure frustration I started flipping through listening modes on my AVR (stereo, Dolby, dts). When I flipped it to DTS X Neural the 15” roared to life and never had an issue like that again. There was something funky about the signal my AVR was sending to the sub - to this day I really don’t get it.

If / when you get your subs dialed in I would strongly recommend putting them nearfield behind the couch. That room looks like a place that bass goes to die. I have an even larger and more open floor plan so I can relate. I resisted nearfield placement for a while but in a room like that, it’s the way to go. Leaving the subs up front and putting the HSU subs behind your couch would also be a good option.

The comment a few pages back about the cone material being to blame is AVS comedy gold, btw.

Good luck. Try not to get overly frustrated by this. It’s a minor setback that you’ll get past. If you do end up returning the SVS for whatever reason I’d strongly recommend looking at some 18” subs for that room. You have the budget for some serious firepower from a smaller ID company.

I agree. It is extremely unlikely that both subs are not working properly and I bet it is a setting in the AVR.

sorry, not to belabor it, but you had the right input selected on the selctor switch on th seldge amp? ("normal" iirc)

Curious if you can confirm good driver movement in both SVS's?? If there is then amps are probably just fine and its some sort of set up issue going on. If little driver movement, that would explain lack of performance. Hard to believe two bad amps, but hey anything is possible.

Minor driver movement. I could feel vibration but no noticeable driver movement.
