My XS30 plays via Denon 4300. I believe I have a number of oddities with my room, based on feedback in another thread and my Audyssey EQ results. Today I decided to increase my XS by 3dB and DEAR GOD this thing is an entirely different animal now. I also ended up INCREASING the crossover on my fronts to 80hz (I know that's standard but was running 60 based on my RP280FAs and 450c) because the sub just came to life and wanted to send more opportunities its direction. REALLY wanted another sub and then I did this.... Now I'm not sure how long I can wait. It's burning to get more bass in here. Not sure if I buy another XS or trade up for a pair of 18inchers. I've only had this thing a month but I'm madly in love.

Welcome to the AVS forum! The 18 inch league is definitely tempting but the PSA 15 inch subs are no slouches either as you have come to experience. Very happy that you are enjoying your sub and experimenting with what you like.

Hi Darrell,

You have the tracking already but here's a couple shots of yours going together this morning. Also, anyone waiting on S1500 in wood veneer they dropped off all of those around 6-7pm this evening. We'll have tracking off to you tomorrow. Thanks again to all for your patience!

All I have to say is the dual 15v's and v1500's killed it today while watching Wind River!
Only -28 and my pants were flapping during the bass scenes!

I have been running 100hz crossover for a couple months now. I have found by running a higher cross, you can dial the subs back a little on trim and it tightens up the bass. In the past when I tried higher cross points, I had the subs too hot and it sounded boomy. All about proper calibration!

Ok, question for the audio scientists. I was A/B-ing the SVS PC Ultra (12" ported) vs the s3000i (dual 15" sealed) with a couple of movie scenes. Both subs were in the same location (at least as close as I could get them without moving each after each test) and dialed to the same levels. My observations were that s3000i went dug deeper and gave me more discernible notes in the 20 hz - 40 hz range. The SVS however, definitely gave me much more tactile response. I could feel it in the seat of my pants through the couch and my legs through the coffee table. The s3000i does give me a rumble and you can feel it in the floor, but just isn't the same impact as the SVS. The couch doesn't shake and the coffee table isn't jumping.

Maybe I am naive, but I thought dual 15" drivers in a sealed cabinet would give me the same tactile sensation that a 12" ported would, even without any room gain to speak of. Am I being naive? The room itself is about 40' long by 13' wide opening into a dinette, dining room and living room with 8' ceilings. Essentially 2/3 of the 1st floor is open either directly or through large door ways to the family room where my setup is. Sub location is mid-wall, right next to the large opening to the living room. Could it be perhaps the configuration of the subs with the SVS being down-firing? Would that give me more gain than a partial wall?

I know everyone will say I need dual sealed or a large ported to pressurize the space, but I am not looking for foundation cracking bass. I am just trying to match the SVS 12" PC from a tactile sensation. Is that realistic from a single sealed? I guess I am surprised a 12" driver is outperforming 2 15" from an SPL output perspective.

I am no expert by any means but this topic is something I have experienced myself. There are few things here. Firstly you are used to the sound of a ported sub. The sealed sub will play much cleaner and tighter bass that you are not used to. The ported will have more output around port tune and so depending on the content you may experience to be even more different. Were you listening to music or just movies? You may want to listen to the sealed by itself for a few days and get used to the sound. I did this myself and ended up coming back to ported as to me the violence of bass was more appealing than clean and tight notes.

Hi,

What you are experiencing is not entirely an output issue. As Ray said, the PC 12 may have a little more SPL near it's port tune. I haven't tried to do a comparison of the two subs, but let's say hypothetically that it is possible the smaller sub has more SPL in a very limited frequency range. But, what you are describing is not specifically SPL-related. Tactile response is the body's reaction to vibration, literally air moving in this case, creating particle velocity. It is easier to visualize this phenomenon with forward firing ports. We can think of air passing out of the ports in the same way that it does from a fan.

But, even with a down-firing ported sub (where the port faces upward, rather than directly toward us), there will be an increase in particle velocity, and that increase in PV will become most intense as the ported sub nears it's port tune. The nature of the air moving through the port is an important factor in the bass tactile sensations that we feel. As the recent discussions of tactile transducers suggested, even using something like Crowson TT's can generate tactile sensations which are hard to distinguish from those produced by subs. Our brains interpret the tactile sensations as more bass.

You may need a little time to get used to the slightly smoother tactile sensation of the sealed sub, or you might find that you really do miss the TR of a ported sub. In that case, you can always go to something like a V1801. There are some obvious trade-offs between ported subs and sealed subs. Sealed subs will typically have more mid-bass SPL and may have a smoother sound to accompany the smoother tactile feel. Ported subs will have more SPL below about 35Hz, and down to their tuning points than equivalent sealed subs. And the sound/feel of the subs may seem more aggressive in the way that you are describing.

I believe it is strictly a YMMV issue. But, before deciding one way or the other, I might give myself a little more time to experience the differences between the two types of subs.

Regards,
Mike

I have had it for about a week now and have listened to a variety of music, movie, and tv. I prefer the PSA for 90% of the material I have listened to as I enjoy the smoothness and blend with mains, particularly with music. I am missing that raw power for those movie scenes that call for it. For example, in How to Train Your Dragon, the wing flaps of the big baddie and subsequent crash after the fight really get everything rocking with the ported. You can tell things are happening with the PSA, but it isn't imparting that raw explosion feel. I guess I want to have my cake and eat it too.

Not sure if you answered this previously , but are you on a concrete foundation? I believe that was always considered one of the no-no's when it came to sealed , large room on a concrete slab. I went against it anyways going from the V1801's to the S36's, and there are some differences in the TR between the 2. It seemed that the V1801's always had some sort of TR going on during anything , kinda of like a mini chainsaw buzzing away at the couch and definitely more buzzing during the right scene. The S36's do provide TR but not as constant as the V18's , which can lead to some more surprising moments when it catches you off guard. The biggest difference I noticed was that there was buzzing on the couches , but when the right scene hit it was like the whole room wobbled and actually became a little disorientating at first and scary living in an earthquake zone lol....So yeah , I think ill be adding another

As the recent discussions of tactile transducers suggested, even using something like Crowson TT's can generate tactile sensations which are hard to distinguish from those produced by subs. Our brains interpret the tactile sensations as more bass.

You may need a little time to get used to the slightly smoother tactile sensation of the sealed sub, or you might find that you really do miss the TR of a ported sub. In that case, you can always go to something like a V1801. There are some obvious trade-offs between ported subs and sealed subs. Sealed subs will typically have more mid-bass SPL and may have a smoother sound to accompany the smoother tactile feel. Ported subs will have more SPL below about 35Hz, and down to their tuning points than equivalent sealed subs. And the sound/feel of the subs may seem more aggressive in the way that you are describing.
Hey Mike ( @mthomas47 ), Hop ( @Hopinater ), following previous discussions on Crowson TT and quoted post by Mike, aint it the way to get best of two worlds for most applications (set aside cases when you want real ear pressure in small sealed room) if you take sealed and supplement it with TT so to increase TR in <30Hz range, so to compensate the roll-off in that region?

Hop, have you tried Crowsons with S1801 in your living room or HT? Do they put your closer to ported in overall impression and TR in particular?

Thanks Tom, they look awesome...can't wait.

I had one other quick question. I'm going to drop a separate 20-amp circuit to run the subs. I plan to use a wireless rca-extender, so hopefully I won't get ground loop issues by running my equipment on two different house circuits. My question is are there any advantages to running the subs on 220v for the new circuit?

Thanks,
Darrell

Nah, might be a small fraction of a dB in terms of max sustained output. Nothing audible. Now, if you plan on trading in the pair of S3000i for say quad S7201 down the road...well...

Everyone keeps talking about tactile response only in terms of SPL. I posted the following a couple of days ago in this thread which includes links to a couple of other threads that go into great detail on what increases tactile response. Note that last time I posted this, I mistakenly linked the last page of the nearfield MBM thread instead of the first page where all of the important info is.

https://www.avsforum.com/forum/113-su...st-thread.html
https://www.avsforum.com/forum/113-su...-response.html

The main conclusion of these threads is that sound intensity (= sound pressure x particle velocity) is what causes things to resonate, including ourselves. Sound pressure is what is commonly discussed which is what our eardrums and microphones respond to. There are also ways to directly measure sound intensity and TR which is also described in these threads.

-Darrell
These threads discuss many experiments with both SPL and vibration measurements using sealed and ported subs with different port tunes. They also contain a lot of anecdotal accounts of particular subs and their ability to generate TR. One thing to note is the particle velocity part of the sound intensity equation is very dependent on proximity and direction of the particle velocity, ie, the closer you are to the sub and the more you can point the port directly at you, the more TR you will get.

There's also been a lot of discussion about using Crowsons to supply TR. While they certainly do that, they only contribute ULF TR. Although the Crowsons can be used at higher frequencies, most users say that Crowsons at higher frequencies don't seem natural and have settled on using them with a 40 Hz low-pass. That leaves a lot of open territory for TR in the upper frequencies (your chest resonates between 50-100 Hz which is where the kick-drum punch comes in).

I still plan to try this for myself eventually, but from what I've read in order to get the best of all worlds you need: 1) a good sub with accurate high dBs and extension down to at least 20 Hz, 2) good tactile transducers (like Crowsons) for ULF TR, and 3) a strong ported MBM located next to you to get the mid-to-upper bass TR. The NF MBM thread also has instructions on how to tune all three of these elements to an overall balanced SPL room response while also getting a natural blend of TR (which is subjective, but it's important to have enough broadband TR capability to play around with to see what suits your taste).

EDIT: One thing that is missing from my 'best of all worlds' is ULF pressurization. For this you need lots of ULF subwoofer displacement (tactile transducers have nothing to do with pressurization). From my own personal experience, I do not like the sensation of ULF pressurization. It feels like you're at the bottom of a swimming pool. Also it's probably not good for your auditory health or your house, not to mention pissing off the neighbors.

REALLY wanted another sub and then I did this.... Now I'm not sure how long I can wait. It's burning to get more bass in here. Not sure if I buy another XS or trade up for a pair of 18inchers. I've only had this thing a month but I'm madly in love.

Before you go and throw money at another sub, turn up the XS30 another 3dB...if not enough, another 3dB...lather, rinse, repeat until you hit the limiters on the sub.

Hop, there's the logical conclusion into your sealed sub venture. Just do it already.
LOL... Oh no, that's got your name on it... I saw that yesterday and that's a bargain at that price so you can't afford NOT to buy it.

That's a really good question. No, I didn't try the Crowsons with the S1801, never even thought of it but I wish I had, it would have been fun.

But motion actuators work just fine with sealed subs and I'm pretty sure that a number of the guys running Crowsons have sealed subs. If I had sealed subs in my HT I would definitely get Crowsons to increase the tactile response of my system.

Truthfully, I think everyone would benefit from motion actuators, whether you are on a slab or suspended floor or have sealed or ported subs... it doesn't matter. Knowing what I know now, if I were putting together a system from scratch I would start by buying duals of the most powerful subs I could afford and fit in my room (no more upgraditis) and then I would buy motion actuators.

But you have to get the subs in place first, they are the back bone to your setup.

Just was poking around the site a bit looking at legacy products, outlet, etc and stumbled on "Tips and Tricks." Good number of write ups there that I think *most* people diving into HT and especially subs like PSAs could benefit from. I know I did. Not sure what topics I'd like to see but definitely would dig more of that Tom!
