It's not a need.

Just nice to have on tap for those really demanding scenes or a wind down session after a stressful day at work.

It's one of those scenarios that's hard to explain to someone who hasn't experienced it.

Personally I wouldn't even see a movie in a multiplex because the experience is rather miserable. Crappy small screens, bad sound, mall atmosphere, just kinda takes the magic out of a movie. Popalocks home theater would get me excited to see a movie in his theater....your local mall? Never.

18,000 Watts is what you'll find in one amphitheater at a multiplex, even more if it's an IMAX... and the bass in one of those theaters will cut off long before it ever reaches the infrasonic lows of a home theater like this one. It's been explained a few times already, in these comments.rolleyes.gif

Under 20Hz, feeling the notes is all a human can do, as the sound itself is not audible. That's the whole name of the game with systems like these. If you "hear" a sub 20Hz tone and think it is audible, that "sound" is actually distortion. cool.gif

My miniDSP has an IR function that allows me to adjust my sub trim realtime at the touch of a button.

Here is my current house curve for those interested:

Don't mind the dip at 70 & 100Hz. IIRC that cuve was accomplished without my mains engaged. You can see that I do have a preference to boost my lowend. With that said, I can adjust it down for a flat response in literally two seconds!

As far as frequency response itself is concerned. For comparison, here is the response of my old Definitive Technology Supercube Reference:
CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), default quality

Note that response is NON EXISTANT below around 20Hz. I was very close to adding a second Supercube to because I thought it sounded great in my room. However, I took the time to research and quickly discovered what I was missing. Even still, reading about infrasound reproduction and experiencing it for yourself is totally different.

If I would have simply added a second Supercube, I would have seen a +6db boost above 20Hz, but basically no improvement below that threshold.

I have been eye ballin' the SI-18s thinking I am going to build a pair.

Bring it on! We are here to help.

Thanks man. Next space I will build is going to have the aesthetics to match the performance. I'm sure my next space will likely be MUCH larger, so...well...you guys know what that most likely means.

Question,

Do you knock your projector out of aim ? After a good bass heavy movie I need to readjust mine slightly. Also, the ceiling moves enough to cause visible picture shake on the stuff near 10hz. (My setup is flat to 10hz)

popalock, I'm trying to do a similar setup when my wife and I move into our new house. Around how much was that setup just for the equipment (speakers, subs, projector, screen, receiver etc...)? If you don't mind sharing of course smile.gif

I had a contractor come out and build a shelf for my PJ. It will viborate like crazy, but for the most part I hardly ever have to adjust it. I've seen my ceiling flex pretty damn hard so I could imagine if I had it ceiling mounted I would constantly have to readjust. However, I'm good at the moment. I'll try to get a pic up of the shelf soon for your reference.

Could it be what I have heard good ol Bill Fritz call 2nd and 3rd harmonics? Like the infrasonic sounds interacting with the physical walls or other materials rather than distortion?

As far as the gentleman making the negative remark about it not being flat. Technically the more subs you add the less distortion you get. Yea, there is a point of diminishing returns. But I don't understand why criticize. People mock what they don't know, especially when what they don't know is on the radical end of the spectrum. But anyone can hide behind an ip address and a keyboard. Popalock, I love your system, its BADA..! And thank you for all your help for many people here on AVS. You have always carried a great attitude and add to the culture of all us nuthead sound and BASS lovers!

Sorry for the slow response easycruise. Tell you what, I guarantee you that the CHT SHO-10's you picked up from Gorilla were pretty much the deal of the century! I really doubt that the Titanium diaphragm CD of the RF-82's would add much (if anything) to the upper end. Seriously, the SHO-10's are awesome. The RF-82's will undoubtedly shine when played full range compared to the SHO-10's, but realistically I think an addition of a good sub to your SHO-10 setup would do the trick! If you had a good sub you would not need to play the RF-82's full range anyway, so it pretty much negates the advantage of the RF-82's over the SHO-10's regardless.

I have no comment on the SW-310 sub. I'm sure it's "enough" for most casual enthusiast, but I can't give it a recommendation because I haven't heard it in person.

Is $1,214 a decent deal? It might be a good deal if you buy the set and it cures your upgraditus itch. Meaning... it's all relative buddy. Try to give the RF-82's an extensive demo before you make your decision. AVS sells Klipsch and I understand they are very competitive with their Klipsch offerings. Good luck my friend.

Thanks Austin! Actually, I have 2ch needs and HT needs, different rooms, got 4 kids, teens and college kids, so the man cave(s) is under constant invasion! Not sure where to put what speakers, especially my long range plans to get the Seaton Cat-12's, as everyone loved them at Gorilla's GTG.

You could pay a lot more for subwoofers, but you wouldn't be getting better performance. That's about as high end as it gets for bass.
1) Plenty of quality drivers
2) Plenty of power
3) DSP for calibration

Realize that 2 18" subs have to "work" less than 4 12" subs. Less heat, less distortion. Effortless and low bass.

Ok, now I'm even more impressed now that I've seen the small size of your HT. Great job crafting such a massive system. Obviously from the feedback is sounds as awesome as it looks.

I got into the ULF game earlier this year with a couple DIY 18's to go with the 12's I had already, and those 2 additional subs have completely transformed my movie watching experience. So I can kinda imagine what your room would sound like, but not really.

Then there are "beer budget" sound systems...

Not mine, but -

These are folded horn subs, with split folded horn midrange speakers stacked on top.
