When you plug the ports, the driver will have to work harder to produce sound because now it is working against an internal vacuum effect instead of being able to easily push and pull air out the port. So it can no longer play as loud before distorting or potentially damaging the driver.

This speakers are setup to work ether way if not they wouldn't include port plugs and they will explain that on the manual.but is good to be careful because the internal air pressure can effect the response and excursion of the woofers,but If you dont listen to movies at reference level you shouldn't worry at all.


I personally never had any problem a loud volumes with the plugs on ,but I can notice right away their limits and I wont drive then over their limit with plug or without plugs.

But i hope watching bluray movies at RL will be fine? Thats the loudest MV i can go. Never listen to music at all.

Sorry. I don't know much of a difference plugging the ports makes in changing how loud a speaker can get before reaching its limits. I just know that it does.

.....and nobody wants to try to figure that out at the expense of their own speakers smile.gif

Okay. How much you guys set ur MV while watching bluray movies? With port plugs or without?
post #46717 of 51483
just be careful and use your instinct if you think the source material is pushing the speaker too much at 0 level, lower the volume a little bit.

I think you wont even achieve a true reference level without distortion with your gear.

I think you said you don't listen to music much, but find a couple songs you do like and listen to them at different louder volumes. Get a feel for where your speakers are starting to sound less good. Then back the volume down from there to where you can tell the volume is reduced (audibly) and listen. Figure out "how loud" your speakers can run where they have a very clean sound.

The reason I suggest music to get the hang of that is because movies can vary widely in volume. You will have to feel it out again with movies, but at least you would have a baseline sense of what volume your ears perceive the speakers as getting too loud.

I have my volume maxed at -10dB as well. I'd hate for the kiddo to sit on the remote and blow up my house! Also on the port plugging, I will have to do the same with my FHs...switched RC-10s to height duty after getting the VSs and audyssey set the xover at 40 hz! There's that corner placement I suppose.



Also I have to just say how much I love AVS...I saw the posts earlier about those posters using manufacturer logos and made myself a Walmart special in about 20 mins. I love it ..please excuse the off angle photo though. Too much glare with the direct angle.

What size print did you do at Walmart? I found that site and talked all about printing one, but haven't done it yet.

20x30...$10 same day pickup coupled with a $20 same size wood frame off amazon. Can't beat that!

  • An even more "full" sound for all types of music. This full sound isn't like when talking about speakers that sacrifice clarity for fullness. This just adds a fullness to the clarity already there.

Movies: (So far have watched parts of Transformers: Dark of the Moon, The Tigger Movie and currently watching Polar Express)
  • With the Transformers and Polar Express the bass was PHENOMENAL! The transformers when shooting or crashing into things hit LOW. The train when it first pulls into the neighborhood to pick up the boy shook the walls of my apartment and if I wasn't in awe I would have gotten up to turn it down. BUT didn't smile.gif
  • My daughter begged to watch The Tigger Movie last night and even with a kids movie, the bass made me smile. Again, like the music, the fullness really made it feel more "theater-like"
  • My brother came over to hear the new sub duo and we also watched the intro song to The Lorax. Great demo material by the way. It is a song mixed with the beginning of the movie where the entire city sings, so you get highs, lows, VERY LOWS and just a mix of everything. Plus it is an entertaining, cute movie.

Video Games: (So far just have played NBA 2K13, Halo 4 and Skyrim)
  • NBA 2K13 is one of my favorite games, but the only thing I can't stand is how loud the game is at low volumes. The bass is also a bit intrusive anyways, so the added decibals from the extra sub kind of made it unpleasant. BUT as I said, it already was that way even before the extra sub.
  • Halo 4 was fantastic when playing solo. With the dual subs and added volume things like grenades and the jet pack actually rumbled the apartment and it was fun trying out all the weapons and items just to see how they'd sound with a bit of extra "oomph".
  • Skyrim I just played for a few minutes but was fortunate to find a dragon in that short of time. This was both funny and not. The funny part was my daughter got scared. The not funny part? My daughter got scared. The dragon flew overhead and when it roared, the apartment shook. When the wings flapped, the apartment shook. It was absolutely incredible. The only thing ruining that experience was me having to pull my daughter out from between the couches who was curled in a ball and crying.

Great job. It must be a real joy popping in a quality flick and feeling that immursed.

Sounds great. Here's some unrequested recommendations from another dual sub apartment guy (S10.3's):

Movies: How to train your Dragon, Percy Jackson and the Olympians, Super 8 for one scene (train crash).

Music: May not be your taste, but for percussion I like Rye Rye (artist name) - "Bang".

Fun stuff.

Thanks for the recommendations! I have 2 of those movies you listed on bluray, with the 3rd being on Netflix so I will try them all out!

As far as music goes, I love pretty much anything, sans hip-hop that has only 3 lines in the whole song (repeating) all about some guy's money, girl, car or drugs smile.gif It gets old. But I still love hip-hop, just original ones.

It is new hip hop, but really interesting. It has a lot of different types of drums - it's a girl rapper, so it may be about guys, no drugs and there may be a car. Also try Karsh Kale - "One step beyond" is more of a world music / dubstep thing with asian drums and really deep eletctric bass / drums.

Macstatic: if you want to test loads of subwoofer-worthy scenes, and you have a high cap on your internet connection, I suggest you take a look at the Ultimate Bass Demo Disc thread. A 50 GB torrent download, but with about 50 scenes and demos. It can be burned on a blu-ray disc or played with the appropriate media player on a PC (XBMC, VLC, etc.). Volumes 2 and 3 should be ready shortly as well smile.gif

EDIT: AVSForum actually censors the name of the torrent protocol? It's a bit ridiculous.

That is awesome, and super affordable. You get to customize it while getting it for $30! Sweet!

Oooh I'll have to try that if my computer will handle it. I don't have a bluray burner, but I'll figure out a way.

I have my S10.3 in the family room, laminate over a cement slab. Would I benefit from a subdude or rubber isolation feet, orr do I want my sub to remain coupled with the floor?

You absolutely will not damage your woofers by playing them loudly with the ports plugged.... the Energy RCs can handle a lot of power,.... so what is more likely is with a typical receiver with it's limited power supply, is that it will start to clip when pushed really hard. This will take out your tweeters before your woofers. The woofers couldn't care less whether the ports are plugged or not. You are simply removing the extra bass response/boost in the frequency that the port/speaker was tuned for...

I have one subdude (now not used due to having the two subs). The subdude I found to be beneficial for two reasons in my apartment. First, I was in an apartment and I felt it reduced some of the "boom" from the downfiring sub I originally had it on. Secondly it raised the woofer off of our thick carpet which was up against the woofer.

Since you have a solid floor, the only benefit I would think it would serve would be if the sub rumbled and actually moved across your solid floor. But I have only seen super powerful sealed subs (like the sunfire) do this.
post #46733 of 51483
Thanks for that information. I kept reading how everyone was recommending them, but I'm sure there were specific reasons that I may have been missing.

Thanks for clearing that up.

No problem. I might even say it clears up the sound a bit, BUT again, that was a downfiring sub that was firing down into super thick carpet. Once on the subdude it had a hard surface with clearance between the woofer and surface.

If there are any sound benefits it definitely isn't worth $50. But if you have the need for one (like the sub scooting across the floor) and you don't have the patience or know-how to build one yourself, then it is a quality piece and one worth getting to fix issues like that.+

this is good to know. i just scared about the port plugs on while watching at reference level.

I recommend XBMC. It's free, beautiful, handles everything, and can bitstream lossless audio to your receiver through HDMI. This demands some tweaks but it works well. It can read DVD and BD ISOs, and have full support for DVD menus but only partial support for blu-ray menus (supports 1 of the 3 blu-ray menu types). You can also just select a .m2ts file and play it without using the menu though.

+1 to that: the RC-70s can take 200W RMS, so unless you have a very beefy separate amp, I doubt you'll reach that limit. Damage to the speakers could be more likely done if the receiver clips or distorts heavily itself. As far as plugging ports goes, it actually *protects* the woofer by increasing internal pressure (i.e. providing back-pressure which limits the driver movement).

Decoupling from the floor is one reason to get a riser such as a subdude. You probably don't need much decoupling from your floor though. Raising the sub can be beneficial (i.e. to distance it from the boundary that is the floor). A riser stuffed with absorbent material also acts as a bass trap, which is good. But you can build a riser for much less than the price of a Subdude if you're half-good with your hands. Not that the Subdude is a bad product; it's just probably not critical to your setup, and you could buy something that performs as well for a fraction of the cost.

I think the concept with plugging the ports is that it takes more power from the receiver or amp to create the same amount of volume. This would make the amp or receiver more likely to distort or clip at a lower volume which could damage the speakers.

Now, the question is how much of a difference does it make? I dont know. But I think it would be a pretty minimal difference and likely would only be an issue when getting into the +5 to +10 range.

But I think the same rule still applies......if it sounds good and clear, you're fine. If you start hearing distortion, turn it down.

While it indeed may be more likely that a given amp clips or distorts, plugging the ports is not simply to lower the volume. The ports create a resonance at a frequency that depends upon the air mass inside them (and thus their total volume). Plugging a port will lower both the frequency and the amplitude of the resonance; plugging both ports will effectively seal the speaker cabinet and cut the bass reflex resonance. The absence of resonance is directly linked with the added resistance the driver encounters when air behind it cannot exit or enter via the ports. Sure, there would then be more strain on the amp if we require it to drive the plugged speaker at the same frequencies and volume as before, but that would defeat the purpose of plugging the ports in the first place. Anyway, the frequencies for which the driver could be damaged (very low ones that require very large displacement) are taken care of by caloyzki's subs.
post #46739 of 51483
Well there's really two separate "issues" at play....

1. Reduced sensitivity
2. Potential additional mechanical load on the woofers

I'm not sure how much of a "risk" either poses in a practical sense, but like you say the common sense rule is "if it sounds good, you aren't hurting anything".

Congrats on enjoying your dual subs. It really does make a huge improvement IMHO!

Keep a eye out for a couple of extras to pic up if you get a chance. My experience with quad S10.3's had been fantastic! I know the whole argument about you can't localize below 80Hz blah blah blah. But' when I compare the quads or even duals to my larger sub that goes below 20Hz, it's not near the same experience. The best way I can describe it is with the quads it's like the bass just exist independent of a location or source. With the single sub by comparison, I always seem to be aware of the sub calling attention to itself. maybe I have a bias in the comparison, but that's the way it seems to this guy. smile.gif
