If you think the Triax is only capable of 110db you would be mistaken. I have yet to see a LTC sweep actually measure higher then max burst output simply because we are discussing long term power vs Short term max burst. So no that is not correct...Short term burst 99% of the time shows higher numbers even with distortion limited tests. CEA2010 max burst testing simulates source content, LTC testing is geared towards showing how well the sub is designed and holds up to abuse...that is why there are no distortion limits for that particular test.

I am just talking 10hz here, you can clearly see the Triax is NOT compressing with that sweep above the ULF region. It behaves like the Sub2 as compression is concerned, is there a limiter? Ricci usually disengages limiters when possible.

This is the first time I can say: It's too loud.

No EQ, No Smoothing


128.6db with just 300watts
0.013% power of out 100% LOL

These nearfields kick some butt.
I've had nearfields in the past, but nothing like this.

130db+
How do you people withstand these SPL's without hearing loss? LOL!

Yep.
90% of the SPL is coming from just that one cone. LOL
They are stacked but the bottom one is further away and thus a lot weaker.
If I built a 2ft stand table I could have both up top covering 42inches of seats at well over 130db.

I don't even know what the max SPL is. I'm too afraid to find out! and this is a guy with 14+ subs talking, so you know it's loud: when... (LOL)

Nice! Me too. Although I am far limited in power at the outlet. Otherwise I might try. No need to trip the breakers if the situation is futile.

Got 14 18's myself, six of which will be nearfield.

Make sure you have them at head-height and facing forward and as close as absolutely possible, instead of on the ground etc; you'll gain 20db; which is the equivalent of buying an amplifier that is 100x bigger. LOL
One skull-subwoofer per seat\guest.
Putting the sub anywhere else is a huge waste of money and time/effort by comparison. (But don't take my word for it, anyone who tries it will see first hand.)

I could literally limit the power to 1000watts to that drivers and apply a crazy ULF-tard house curve to it to counter-react the nearfield response, which would turn it into basically a ported-sub of sorts; but with extreme efficiency, output and cone control.
How deep I could make it go and how many db's I'd lose above 40hz I'm not sure; that's the trade-off though.

I think I might be able to force it down to 17-20hz because the 21 has a lot of excursion and displacement, which is the main limiting factor at those frequencies. Sheer brute-force might just work. I'll have to give it a try tomorrow.

Whatever the SPL I will get above 40hz, would probably STILL be too crazy to withstand, so it's like: "who cares what it is, it's too-much is what it is". We aren't looking to burp +180db here, we are here to listen to music and movies instead. LOL!

The video of that sub at ear height is priceless! "Sub headphones"...I love it!

Interesting comments though about how big of a difference raising your subs to ear level like that...20db gain? Is it that big of a difference then them being in the same position, but on the ground?

Do you get better pressurization/weight with them ear level like that? Are they more easily localized with them up high like that (assuming your perception would not be influenced by that 18in driver by your ear...)?

Version 18.0 of the ULF Calculator is now available here.

  • Estimates added for the Reaction Audio PS-18X and PSA Triax T-18
  • Corrected rounding issues when adding multiple subs. No rounding exists now in calculation. (Thanks@Pain Infliction;!)
  • @mktheater back so all sealed alignment
  • @Sibuna; added
  • @d_c; Tactile Feedback FX added (suspended floor)
  • @ahmedreda; added 5 crowsons to TF FX

My subwoofer crawl, predicted this:

Haven't measured the actual of the bottom sub yet.

With my clone at somewhere between 10-50% power (or 300-2200watts) I got this SPL @ 38hz in the golden seat ear-level.

This isn't all of my subs, nor at full-power.

Hey, Dom... just noticed. You've had me down for six JBL's when I've had twelve for the past year.

Don't worry yet though, I'll be moving some stuff around and will have a whole new score (with nearfield/tactile upgrades!) so I'll just notify you once I've done that and then we can update me scores.

Here is the actual:


A 6-20db difference by putting it near your head, instead of on the floor.

That is the equivalent of adding somewhere between 4 to 100x the wattage; it's a major efficiency advantage.

BTH, have you ever thought that the original position was just bad? Raising subs don't add SPL unless they were in a null, it does help with smoothing the response. If it were a fact then anyone who raises their subs should get more SPL and that is not the case.

Rasing the subs will effect the vertical room modes. This may cleanup the sound a bit but, should not add spl unless the previous location was a null as mentioned.

So you are saying that there is a 7hz to 200hz low-Q null? Sounds highly unlikely to me...
I have never seen a null span much more than 20hz; and I have eq'ed 8 different theaters over 14 years of experience with 31 subwoofers of 10 different brands.

It gets louder because it is closer to your eardrum, in my case 1/4 the distance.
And every halving adds 6db (up to a point I'm sure...)

That's the only explanation I can think of.
The UMIK-1 isn't lying to us... hehe

There is no magic, you are removing interference, moving the subs closer and getting a better close mic response, not very good for ULF as you are removing the room. Having much louder 20hz and up is like every sub out there. You had a null down low to make the differences seem greater. Try measuring all the locations on the floor and see where it gets smoother. I can imagine the localization of a sub being at my ear drum.

I think it would raise spl because the driver would be so much closer to the mic that is measuring said spl.

If you put a driver right behind your head it would have to be louder to your ears than the same driver sitting on the floor right?

Of course, but how does one sit with subs at their ears and not know where the bass is coming from? It would be like someone blowing in your ear all the time, I would need to slap someone eventually.

Haha, I didn't say I would like it. However... I haven't tried it so who knows.

I do know that I'm loving my new nearfield SI 18. That combined with the Crowson makes me no longer wish for a suspended floor. I wish I could have a 24" back there but no way I can fit that with 2 rows.

Using your SI 18's? How many?

I do wish I had some more headroom on the nearfield sub but some of that is due to just using one channel of an inuke 3000, I bet I could get 3 more db's just by giving it more juice. The rest is because I only have the one driver. It's a trade-off but I like the one driver because I can crossover almost wherever I want and the bass sounds/feels like it's coming from in front of me. If I had multiple drivers to the side of the one driver the bass would be much more directional from what I have experienced.

I thought about going with a uxl or HST 18 but at 149 shipped B stock there was no decision to be made.

I am loving my SI drivers! They are really great at the low stuff, under 20hz.

Scott,
Knowing how the JBL drivers sound and knowing how the SEOS sounds along with the SI's all you need is tweaking. Your system is second to none! I have the luxury of a small room so I don't need that many 15's if any. I am putting togther that new JBL speaker and let everyone know how it stacks up. I can tell you guys switching to sealed and adding the LT to my IB type enclosures is the best yet! Better than the ported 7hz. I have 24 inch cubic foot boxes for two sealed 18's. So 4 nearfield and they dig very deep!

The rest is because I only have the one driver. It's a trade-off but I like the one driver because I can crossover almost wherever I want and the bass sounds/feels like it's coming from in front of me. If I had multiple drivers to the side of the one driver the bass would be much more directional from what I have experienced.

I thought about going with a uxl or HST 18 but at 149 shipped B stock there was no decision to be made.
Hell yeah, man. I like the way you're moving. Though if I were you I'd work with what is there and then consider more/bigger subs. Yeah, you could juice up the power. Are you doing low end boost on the nearfield? If not then you should have some ample headroom to power up >30hz for more punch with no worries of overdriving the HT18's. Could get >3dB if played right. Just one of your options.

So for the past year I've ran eight HT18's and four RLp18's all of which are up front. I'll be moving the subs around this or next week (as soon as I build this new screen I've been wanting for half a year. Oye!) and they will be in other places. I'll keep the eight HT18's up front and move four (two DO enclosures) RLp18's to be nearfield in the rear corners. For a while now I've had two extra RLp18's just sitting on the floor doing nothing. I think I've decided to build a riser and incorporate the extra RLp18's into it. I thought... "well, four 18's nearfield should help punch up the bass some. Yeah, well... I think I'll build a riser too to really get some shake. What the hell am I going to do with these extra 18's? Eh, why not put them in the riser?!" Oh man. Six 18's nearfield with two of them right under my butt.

If this doesn't do it for me I don't know what will.

Scott,
Knowing how the JBL drivers sound and knowing how the SEOS sounds along with the SI's all you need is tweaking. Your system is second to none! I have the luxury of a small room so I don't need that many 15's if any. I am putting togther that new JBL speaker and let everyone know how it stacks up. I can tell you guys switching to sealed and adding the LT to my IB type enclosures is the best yet! Better than the ported 7hz. I have 24 inch cubic foot boxes for two sealed 18's. So 4 nearfield and they dig very deep!

Aww, thanks.

Not like yours is any slouch, James.

My room isn't that much larger than your room. Taller definitely. Lol and I'm so short! You're the one that needs the tall room.

Yeah, the SI's while not touting as IB drivers really lend themselves to a proper installation as such. They have a pretty low natural Fs which should give you a nice, wide impedance peak in the 10-30hz area. Effortless deep bass and with so many... hell yeah.

Interested in what you think of the comparison of speakers, fo sho.
