http://www.avsforum.com/avs-vb/showt...5#post14456895 This is a good audessey setup guide, helped me alot when i had no clue lol. I also have Monitor 70's and it does set them to large in autosetup, i change them to small and x-over them to 60hz, all the rest are set to 80hz and sub to 120. My avr has me set my sub volume before it runs setup, cant remember what level its at atm. good luck!

Is the LPF of LFE set at 120Hz?
Are any of your speakers set to 'full range'?

With your speakers I would expect Audyssey to give you numbers in the 40-50Hz range, raise these to 80. If any measure higher than 80, leave them.

Also, your brand of Audyssey is '2EQ' which doesn't add any filtering of the subwoofer only the sats.

Ha thanks, you guys are awesome. The music sounds a lot cleaner. (I was testing it with the television music stations via component in, Pandora(iPhone), and MP3(iPhone).) I am getting a lot more bass from the woofer with it set to 120hz as well during HT.

Audyssey had the sub set at -7db with the knob at 50% volume. With all the speakers at 40HZ and the sub at 60HZ.

So with the 2EQ would it be better to or is a option to not run the LFE and run wires/RCAs since I have open channels available. I am confused by the negative effects of the 2EQ not offering any filtering of the signal to the subwoofer.

You all might get me hooked just yet. lol

-7 is fine. If you want to juice this up or down, do it in the recever and never touch the gain on the sub after calibration.

I would run it with the LFE input as this is a direct input and takes out the crossover and any delays that might be present. If you decide to go with the LFE, you'll have to rerun Audyssey and after the calibration go back in and change the speaker/sats c/o's again to 80Hz. The LPF of LFE should stay at 120Hz.

You all might get me hooked just yet. lol

Has anyone run into any issues with the auto switch not automatically turning of the LSP12? Also, has any had any issues with their sub becoming very hot? I just bought the LSP12 for my father and he claims that the auto switch is not automatically turning off and that the subwoofer is abnormally hot. Any thoughts would be appreciated...he's going to call technical support on Monday to see if he hasn't set up the sub properly. Thanks.

Is he putting the 'auto' switch to the center position? Setting it to the 'ON' position will leave it on all the time.

I have two 12 inchers and one does get rather hot to the touch, the other one doesn't.

Second sub arrived today. Packing was done very well. No issues with the box. Cosmetically perfect and the tubes are fine. Hooked it up to the sub 2 output of my rx-v765.

Right now I have them next to each other under my center channel speaker. Both are set with the output at about 11 o'clock. I do have a question about phase. Should I leave one at zero and one at 180? Or both to zero? They will be eventually stacked in a corner but for now, this is how I have to run it.

Thanks and well done Lava,

I ordered two LSP10s early this month and at first I was underwhelmed with how they were performing separately in two different HT systems. I had to raise the volume quite a bit to get something I liked and even then I was underwhelmed. I was having second thoughts and was actually thinking of just sending them back, I had loose tubes on mine and well was a bit disappointed.

Then last week I ordered a BIC PL-200 for one of those HT setups and decided to put the two LSP10s together in my small bedroom HT to see how they sounded and wow! What a huge difference the second sub made to my room, now I don't have to put it as loud and it sounds much better.

I get nice punchy bass coming out of these bad boys and now that the tubes have been better glued on there, I'm a happy camper! These things hardly sound muddy and you get that nice clear bass on music especially. They don't shake my room like the BICs do, but these subs together sound really awesome and you can still feel that nice clear punchy bass.

ratm, some people on here said that they like them with one at 0 and the other at 180, I tried that with my Lavas and found out I liked them both at 0, so I guess its just what sounds better to you.

I turned both of mine to zero. wow. Major difference.

As a beginner to the subwoofer scene, I would like some advice on where to put the frequency and volume knobs on the lava 12. I don't have an SPL meter or anything to tune to exact frequencies but can anyone give me a general position to keep the knobs at so I don't end up damaging anything, or should I just go by what sounds better? I will be listening to music on this one, so if that makes any difference on where I should set the knob, please let me know. Thank you.

With loose tubes, do you hear a rattling sound? Also for the ground loop issue, has anyone noticed this with the new release?

Never had an issue with loose tubes, and I dont have an issue with either version. Both are set at the 11 o'clock position.

Both of my LSP10s came with loose ports and I got them about a month ago, I guess that was an older release? I glued them back on and at first they rattled for a bit, but I don't hear the rattle anymore and they sound pretty awesome today. I still hear a small hum on mine, but its barely noticeable and you can only hear it when the volume is raised really high and you put your ear next to the sub.

What receiver do you have?

I would not put the volume on the sub greater than 50%

The frequency knob should be set to max around 160hz

Im not using a receiver. I have it hooked up to my computer sound card. And as far as 160 hz, where is that on the knob, say in relation to a clock. At 12 o'clock, 1 o'clock?

Craziest thing is I just made this discovery last weekend while recalibrating my system. I was gain matching my pair of LSP10's when I noticed that if I dialed the frequency back to about the 120-160hz range the SPL would register a 5-10dbA boost. Up to this point I had them dialed up to 200 hz but now I have then dialed in around 155hz... :shrug:

about 1/4" (1cm) back off the 200hz marker...

Yeah well its acting as a low pass filter cutting the subwoofer above this frequencies off and letting the smaller speakers do the hard work. It can even work to clean up bass. If you have speakers that you cross over with a receiver at 80 Hz I recommend setting the cross over at around 120hz if you receiver has no low pass filter

i received both subs with ports intact and both producing a ground loop hum...once again this is NOT a problem with the subwoofers...it is with the electrical system in the house...mine is from my cable tv connection not being properly grounded...

That doesn't sound good as far as quality control. The AV-123 MFW-15 suffered from the same problem. Some of the "heat sinks" got over 115 degrees. Like everything else, hum, air leaks, defective veneers, the heat problem was pretty much dismissed as an isolated incident.

Good Luck

I don't know if I would blame it on QC as I wouldn't think that they test 'em before shipping. Could just be an anomaly as I haven't seen any other posts about it. Loose tubes ...that's a QC problem which I don't have...yet.
post #984 of 1392
I dont have any issues at all with either of mine.

No loose tubes, no hum (unless I turn the volume all the way up), and no hot amp issues.
post #985 of 1392
I had one port that rattled at very high volumes and found the pad underneath the port had come, put pad back under the port and problem was solved.
post #986 of 1392
i can say for sure, now having set up both subs properly, that these are performing way over expectation....i did a frequency sweep and they did indeed reach down to 24hz....pretty awesome for a two subs that cost me under $400....one of them was performing much better than the psw micropro 2000 it replaced and that sub has a retail of $1100

i have no bottoming out noise, as promised.
post #987 of 1392
Just thought I'd post a picture of the Lava sub and the one it's replacing. I does an amazing job of filling a 19 x 12 x 10 room. It wasn't hard to be better than what I had but for the cost vs how great everything sounds it's a homerun.

Hey we wanted to tell everyone thanks again for their patience as we redid our packaging. We have fulfilled all the back orders on the 21st of January and all subs should have been delivered. We are happy to say that even though some of the packages arrived beat up none of the subs did.

We will continue do everything we can to make sure we deliver a great product at a good price.

thanks again

Peggy/Eric

Thanks Eric! i am very happy with my 3 lava subs!
post #990 of 1392
Is this what I need to remove the hum? If I put my ear real close to the sub, I can hear the hum and would like to know if it is the ground loop issue people are speaking of.
