post #7951 of 18718
I think I understand what you are trying to accomplish - you like exaggerated boosted bass below 60 hz ish - nothing wrong with that. Yeah, the 212's (or probably any of the SEOS DIY speakers) will have no problem being crossed at 60hz with no stress even at crazy volumes.

However, maybe there would be a cheaper solution. If you had a minidsp or sms-1 you could cross over at 80hz or even 100hz and just pull down the bass in those higher frequencies so that you don't get that boomy sound from the sub that you don't like. Then you wouldn't be stressing your speakers and you'd still get that boosted exaggerated lower bass that you like. Could that be a possibility? I'm not trying to talk you out of buying speakers but if you really like how your current speakers sound and the only issue is they can't be cranked up down to 60hz maybe my idea would work?

Had thought about that, but I start to localize my sub on some stuff now at 80hz, and that may be because of the boosting I'm doing...or it may be because of my room..... I really don't want to take the sub up much higher to compensate for inadequate mains. Plus, at some volume levels, there is compression and distortion from my mains even in the midrange frequencies -- while they still sound tolerable, there are certainly still songs that I want to push a bit harder, and can't. End of day, I need new mains, lol. It's just finding ones that work for me in a budget and package both my wife and I can swallow.

If I still can't accomplish what I want, I may look into the sms-1 or minidsp or some solution -- but I have this...OCD...about me when inserting unnecessary A-D/D-A steps in my chain. I suppose for bass frequencies it'd be very much less obvious, so I'm less opposed there, and even in general the range where those steps (HF) could even theoretically degrade (if at all) the signal I probably can't even hear any more, lol. But, still fitting yet another piece of equipment into my chain is less than the most desirable, for me. I'd like to just get the x-over and room EQ right, and then be able to set the gain on my sub for my nominal case (tv/movie viewing) and when I listen to music that I want a nice boosted bottom end (like, when I'm treating my house like a nightclub, lol) I just have to reach for the Denon remote and crank up the sub channel level. That'd be ideal.

Of course, in my competition car, I had a few extra steps to enter "that mode" where the bass blew my socks off. Disengage both the L/R channel 1/3rd octave EQ's (which had the effect of making the horns slice off my face) crank the x-over to the sub from 40hz to 60hz, then boost the gain on the sub channel and lower the gain on the high x-over channel to assist the horns ripping my face off. I knew the system curves for flat were way out of whack, but for that music I just cared less about overall SQ, and more about getting a back massage while grooving out driving, lol. Course, it really got excessive when it was loud enough that my glasses would bounce around on my nose and my vision would blur....but...hey, lol. At least now I don't have to worry much about frequencies above probably 10kHz, lol.

Jim I ran Audyssey and Audy set my 212's at 60hz. Should I bump it up to 80?? I have them set to small and set them to 4ohm.

Is there a setting for what ohm the speakers are? I've never seen this. I have a denon, what receiver are you using?

They are capable to 60 hz so I would try 60, 70 and 80 hz to see what you like better.

Some receivers have a 4 ohm setting for speakers. Typically this setting limits output to avoid blowing up the receiver. These speakers are so sensitive, it probably doesn't matter.

Hey, it's the South Jersey guy with the 212's.... I was told I could invite myself over to your place to hear them, lol eek.gif. (See above a few posts, lol).

Guess that depends what the impedance/phase looks like, seems that's a pretty good tell how hard they may be for an amp to drive. Don't know that I've seen a graph for that.... But, I'd suppose that in most rooms, you're very right -- they'll make your ears bleed before a good receiver runs out of steam.

edit: But, I'd still make darn sure it has more than adequate ventilation, because it'll certainly be drawing more current, and need to dissipate that heat...if it can't it may protect itself, or just release the magic smoke.... I've done that to a previous Denon...wasn't fun.

They're down 3dB at 60Hz, so you'll be fine set like that. What sub(s) are you running? I don't recall if you mentioned that on Saturday. Depending upon what they are you might want to try 70 or 80 as well, but at that point it's dependent on your own preferences more then anything else. With 212's for mains I would tend to put the crossover as low as I could, so the sub is just handling the deep stuff, but you may prefer the opposite.

How are they doing in your HT? I would imagine you've thoroughly broken them in by now.
post #7958 of 18718
Here is my 212's with no sub. With subs and mbm I can get that dip at 100hz out of there, but I think I'm getting cancellation due to the distance of the speakers from the front wall. Anyway, that's not the point of showing the graph, I just wanted to show how low they go.




I can crossover as low as 50hz with no problems but I prefer the sound of a higher crossover.

I thought I was good to around 55hz, but I remembered it wrong looks like I'm good into the upper 40's.

Honesty Jim, I have really been to busy to work them out. Watched two movies this week, but mostly dialog. (Django and the Town) I have dual Power Sound Audio XV-30's I moved the XV-30's to a new spot, (Front Corners of the room) considering the 212's are massive beast and I had to make some changes to fit them. I have to say I am quite impressed with the subs. They are like new subs, bass is much deeper and richer. I still want those S2's biggrin.gif

Look what just arrived from Deutschland.


Interesting but effective packaging.


Initial placement ...?


I like it ... cool.gif

You have dual XV-30's and 212's? eek.gif It's probably like Andrews GTG every night at your house. tongue.gif

Looks good Rob! I plan on ordering one after I get my 228HT's.

I have 228's and an S2 in a well treated 1500 cu foot room. I have never experienced 212's, but I imagine that, in my small space, I am getting pretty close to what you guys experienced.

Once I get my 4 Triple 8 surrounds installed I will be in audio heaven.

So in the end you'll have three 228's, four Triple 8's and an S2 in a room that's probably somewhere around 13x15x8? Not sure you'll be is audio heaven though, more like a doctors office getting your tinnitus checked. tongue.gif

Those are pretty much the dimensions. The surrounds will be hidden in the walls and the LCR and sub are already behind a 110" AT screen. It is a fun room to say the least.

Looks great! Ours have not arrived yet, not sure when they will. All it says tracking wise is that the package is in it's destination country.

Yeah, not bad. I kind of surprised myself ordering them and they are the only thing like that in the room. Not really a bumper sticker kind of person but since I have the full JTR setup (9 speakers and two subs) and, they are such a straight forward, no frills products, I thought it was appropriate.

Good conversation starter as I can tell the story of Jeff, Mark and Tom Danley all working together at ServoDrive back in the day. Kind of interesting that those three worked together and now they have three companies that compete with one another yet, they are still good friends. To me their products represent the best of what's available for home theater audio ... and they're good people. cool.gif

In my room the Noesis 212's play strong to 50hz but I too use a higher xover (currently 70hz for the LCR's). Omnimic is a great tool to help understand what is going on in your room. With all my room treatments and the asymmetrical dimensions of my HT space makes it easier for something simple like Audyssey to provide a decent FR at most seating locations in the room. If I was really anal, I'd get a manual EQ and tackle it but the system sounds great to me and I have better things to do with my time. No long cold winters here in sunny California ... wink.gif

Anyone have any suggestions on how to stop light fixtures from rattling? I've noticed recently that my light fixtures seem to be rattling with a lot of bass. They are tight in their slot, so it isn't the fixture really rattling against the drywall ceiling. It is more of the actual thing that the light twists into. The lights are in their tight too, I made sure they weren't rattling loose. But like if I kind of "fling" the light and let it go, it kind of springs back/forth real quick and makes the rattling noise, if that makes any sense. I can take a video if it doesn't make sense what is going on here.

But I'm pretty sure that is what is making the rattling noise that I have started to hear sometimes.

Any suggestions on how to fix it?

i had mfw-15s years ago, and used a auralex gramma under them, my glasses in my cabinets stopped shaking, nowadays i have 2 under each of my dts-10 subs, works wonders.

I use an MRX-500 to drive 3 vented Triple-8HT's and 4 Single-8HTLPs. I have 2 Submersives for the low end. This is in a dedicated theater with a lot of bass trapping and some broad-band absorption at first reflection points. I'm very happy with the performance of the system. One important positioning issue for me was toeing in the left and right mains about 45 degrees, that significantly improved the imaging. I had a home automator install all of the speakers/subs (they had done the wiring and integration already), and while I directed them how to place everything, I never saw the placement of the speakers/subs behind the AT screen. It sounded okay, but not great. So soon after that I took the screen down and moved the speakers out laterally and toed them in, then re-ran ARC. Big improvement. If you take some time with the system optimizing it, you'll love the result.

You can probably fit an actual banana in one of those beasts.
