Close, two 10" subs were the other choice. Gonna try the one 12" first. If I need the two 10" ones I'll return this one and get those.
post #933 of 1392
definitely would have chosen the two 10's over a single 12.

Ok , so last night i did the crawl test with my spl meter and found three areas in my living room where the bass sounded the best. To make room i stacked the 2 tens for the night just to see what it sounded like and i wish i would have had them that way the whole time. They sound much better colocated. Going to leave them colocated when the 12 arrives.

With my size room and the distance to the listening area it was unnecessary. I also had very limited space to place the second sub.

Hello everyone,

If you look at the product pages for both these subs they have almost identical specs. With the bigger box and woofer in the 12 I had thought it would go down much lower, but it seems like it's main advantage lies not in extended frequency response but in more SPL across the board?

I would be using the sub mostly for music/music production to complement my 5 inch stereo monitors (M-Audio BX5a's). My audio interface/preamp has dual outputs and the one left after I hook up my monitors to the 1/4 inch L/R out is a stereo 1/8th inch line out. Luckily the lava subs have a stereo line in. It seems that subs from other IDs like HSU and SVS assume a 7.1/movie setup and don't provide line level inputs and so I couldn't buy them even if I wanted to!

The room size is 10x10x8. I guess I will be seeing the 40hz boost since I'm using the RCA inputs and will have to EQ that out to flatten the response curve?

Thanks,

Dan

From speaking with Eric at Lava when making my order the 10" sub is better for music. I also think in a room that size the 10" would be plenty.

I'm getting my 12" on Monday and will post a review after I get it.
post #939 of 1392
Thanks for the quick reply Fencer!

I have another question,

If I stuff one or both ports of the sub am I right in assuming it would make the bass tighter/quicker at the loss of some SPL and frequency response?

Dan,
I'm not sure about that, I can say that if you call the company you will more than likely get Eric, the owner, without going through any crazy wait. He is a great guy that will tell you anything you need to know. He was extremely helpful when I made my order. You also get a 15% discount for being a member on this forum.

Got mine yesterday. Everything looks good on it.
post #948 of 1392
I received my lsp12 sub tonight. Packaging was a lil dinged but the sub was perfect. Unfortunately with it being so late at night I can't crank it up but at normal levels it sounds great even in my 3500 cubic ft room. I do notice a very slight hum if I put my ear next to it so I will have to purchase one of those plugs but I don't notice it more then 2 or 3 ft away. Very happy with my purchase and think this sub was well worth the wait! I'll post more tomorrow after I get to play with it at higher volumes.
post #949 of 1392
So, I havent been able to listen to my stereo at high volumes yet but i will say at lower volumes the 12 is hitting lower then the tens did. The 12 and the 2 tens seem to be blending in very nicely right now.

Ok, I received my lava LSP12 on Tuesday and finally opened it up yesterday, but since then I have been trying everything I can to get this thing working. I think my sub might have something wrong with it, but the exterior is perfect. My box was a little dinged up like sddeck's box was, but the sub itself has no noticeable damage. My question to you all is what methods can I use to make sure this sub was not DOA? I have tried many things and I have yet to hear any sort of sound come from the sub. No feedback when plugging in connections, no humming, nothing. My previous subwoofer works fine and I did not change any connections in the way I hook each sub up. I tried the lava with both my computer and HT system and I have yet to hear any sort of sound come out of it. I don't own any sort of SPL meter or any testing equipment to see if I am getting anything out of it. Whats weird is the sub turns on and the red led lights up. I don't know what I am doing wrong. Anyone have any advice?

What ht receiver do you have? What have the knobs on the sub woofer set to?

Well I am not home right now and don't know the exact model of the receiver. I believe its a Yamaha. It's been awhile since I have messed with any connections. But that should be irrelevant since my previous subwoofer works fine to this day on it. The knobs are set low cause I didn't want to it to be super loud and I tried adjusting the frequency and volume knobs while playing a song with my computer and nothing came out of the lava sub, but my energy sub played fine through the rca connection. And this lava is supposed to be for my computer, so I was just testing it with the HT to make sure something wasn't wrong. But I have tried playing with all the knobs and switches on the lava and have yet to hear anything. But I leave the volume knob low when testing cause I don't want to blow up anything on the first day. I have tried adjusting the frequency settings knob too. Still nothing.

Did you put the 'auto' control to the middle (auto) or to the far right (on)? It's the bottom switch on the back of the amp. Did you plug the rca cord into the LFE jack?

Ok thanks. This was it. When reading the manual, I kinda skimmed through it and only glanced at the auto on function. I thought there were only two functions on or off, so I just left it off because I didn't think I would use the auto on function. I didn't know there was a middle function. The tip off was probably the red led. When operating, the led is supposed to be green. My old sub didn't have any of these features, so it was all new to me. Thanks for all the help. Now I can start enjoying the lava sub. As far as build quality goes, I don't think anyone will be disappointed, except for maybe the ports if they fixed the glue problem or not, but I can't say anything bad about it. And by the way, to answer your question, my RCA is in the red and white. It's not supposed to be in the LFE jack right? When I tried this, it played my music that was supposed to be coming through my speakers but very muffled. I'm guessing that would not be the correct input.
post #955 of 1392
Putting it all the way to the right (ON) will leave it on all the time. Putting it in the middle will allow it to only come to life when a signal is being input to it. Kind of like a sleep setting.

If you have an LFE (subwoofer) out on your receiver you could put that in the LFE input on the sub and then the AVR would do the bass management if it's capable. How old is the receiver?

Ok so I had a chance to play with it today. Now this is purely based on my complete inexperience, FYI. I am running a 5.1 setup with Polk Audio Monitor 70s series II up front with the CS20 center. In the rear i am running Monitor 40 series IIs and pushing it all with a Onkyo HT-RC260. All is calibrated with Audyssey. So the LSP 12 (via LFE) fills in quite nicely for HT even at higher volumes. I did find that in scenes that do have deeper base and explosions for instance, it does leave more to be desired but as I have gathered this is where the higher dollar subs come in. But it is worth noting that it doesn't ruin the experience as others have notated, the "bowing out." Overall I think I have to say for HT which was the primary reason I purchased this sub it has exceeded my expectations even with my large room (3.5-4k cubic ft). It even vibrates my couch which is located 13ft away at modest volume levels.

Now when I tested it with various hip hop music at higher volumes I got a lot of chuffing(sp?) from the ports and that mechanical clanking sound. Alternative and classical rock did not produce any/much clanking but did have some port noise. For those looking for the loudness factor it did rattle the picture frames and other items throughout the room some but i doubt the neighbors across the street will hear it. At modest levels of music though again it sounds more then adequate.

Overall my usage is about 80/20 HT so again I have to say I am very satisfied with my purchase. I have yet to move it around to other areas in attempt to take advantage of my rooms resonance. But I have to say compared to some of my friends' subs I definitely got the most bang for my buck here. Will it fulfill a "audioholic?" No most likely not, but for your average joe who is looking to complete/build a good system I think it will fill in very nicely and still present some "wow" factor. It just wont go over the top.

Again this is all based on a complete amateur's observation but I do give it two thumbs up (for HT at least).

sddeck...It sounds like you are happy with your purchase, I would be really concerned about the port noise and mechanical clanking you discribed. I havent heard anything from Lava before so I cant say if what you hear is normal for their subs however I would test a few more offerings before ending your search.
post #958 of 1392
sddeck, did you set the gain on the sub correctly? almost sounds like it was too high. Rule of thumb that i have learned from reading here is to use the built in sub test tone on your reciever and set the gain so the sub is at 75-78db before you run audessey if your reciever doesnt have you do it in the auto setup. Just an idea to consider good luck

Were you playing mp3 tracks or CD?

A few questions;
What is the level that Audyssey set for your sub? -15 is the max and if it shows this you need to lower the gain on the sub and rerun Audyssey.
Did you set 'double bass' to OFF?
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.
