I would use the microfiber. The ones I have are all very soft -- until they get dirty!

My LSI15 main speakers have a piano black finish and a microfiber cloth has worked well for me.

I hope this may help a little (link from the bass master list thread):

The white gloves that come with piano finish subs/speakers seem to be ok but again that is a very small "cloth."
Thank god I replaced my SE piano finish with a matte black. wink.gif There's just too much "cleanliness maintenance" on the piano finish.

Any ideas on how I can get it closer to 0db? Thanks!
What's the position of the volume knob on the subwoofer? Do not start with 12 o'clock position. This is too loud to start with. Start with 8 or 9 o'clock position.

I have to stop pretending I know something about this because I read the numbers and go actually try it out. It's on my ToDo list now.

I've heard Popalock's dual LMS's, very nice, but's he's upgraded to something crazy. Something like 16 of the SI drivers eek.gif

In order to truly appreciate that scene, you need to play 7-8hz with strong authority. It's a very cool effect...like a 'wobble' effect. My FTW21s have some INSANE excursion for those brief few seconds. Not sure about the SI drivers, but one of my FTWs have approximately the same displacement as four 18" Dayton HO drivers...and I have two of them + the FV15HP in my 2000cf room.

 

You won't see that excursion or output out of the FV15HP because it just doesn't play that low. It's designed to have a steep rolloff starting at 14hz or so.

I know this may be a Stupid question but I have a question regarding fv15hp mcaac sets the db to -0.5 and the volume on the sub is 3 clicks above 80 I run my sub 6 db hot which is great for movies but not so much for music I listen to a lot of rap is it safe to turn the volume on the sub to 3 a clock or is that dangerous basically I would like to know how loud I can play the sub at?

If we just look at th graph (without actually listening to the track), for the good first 50 seconds, frequency band between 70hz and 80hz lights up red. So we need not just low bass, but also good midbass in order to play loud in this good 60sec take-off scene.
Then between 55sec and 85sec, we should mostly feel pulsating air moving.
Then between 103sec and 108sec, there are some strong low frequency rumbles. But again the energy around 35hz and 50hz is strong. A lot of houses and rooms have structure resonance around these frequencies which can enhance the experience a bit.

Start at -10 and as your hearing acclimates to the sound level, increase a few dB's until reaching +/- 0 dB's. I find it much more enjoyable to my hearing sense if I do this as opposed to just blasting my hearing from the gate.

I didn't realize that was really a strategy other folks use, I do that all the time. Thanks.

I've seen this a couple time, but this is the first time with duals.

My wife has sensitive hearing. If I start at -10 she places her finger tips on her temples. I experimented by starting out at -17 and found that when I saw her relaxed in the recliner, I could slowly inch the volume up and I didn't see her grabbing her temples. Unfortunately, above -10, she starts wrapping her fingers around her temples so -10 is the best I can do for movies like "Blackhawk Down."

Sniff, sniff. tongue.gif

For me, like most here, I enjoy it loud and have been known to go to +5 and due to my wife's temples, I find that I enjoy it more when I creep things up from a lower level.

This is a little awkward but... I'm actually rooting for a blackhawk to go down.

EDIT:
I take that back, it's been awhile since watching the whole thing and I forgot how real world and graphic this movie is. Definitely stirred up some emotions for me. Please don't go down blackhawk.

There are some very good bass scenes but some scenes could have gone a little more. It's like some explosions were huge and other were just not all the way there. Not the sub's, they did great, but the content. The helicopter blades are always nice. Also the bass really starts off slow and picks up later. I can see why smigro said underwealemed but then there are some bass jewels in there.

That is just it. I always thought that the 5 star movies had a lot of bass throughout the movie, not just in a scene or two. Now that I know it is just a few scenes here and there I am not concerned about my sub.

What else have you watched? Immortals (which is on netflix in 5.1 DD+) and war of the worlds have been my go to bass demos lately.

The helicopter blades infrasonic is kewl but it's below what we can audibly hear so it's a subtle feel thing. Crank one of those scenes up and watch your woofers. Another thing weird about black hawk down for me is the machine guns don't seem to have a lot of bass impact which some movies do well with.

I felt the same way about the machine gun fire in BHD.

I have watched quite a few movies...Avengers not being one of them yet. I would have to say the movie with a scene that most mpressed me so far is The Hurt Locker. That opening scene when the bomb goes off is some of the best bass I have felt yet. I was also impressed with the audio in Battle: LA. Not the best storyline but the audio was top notch.

I finally had a chance to set up my new system this weekend -- a 3.1 setup with CMT-340SEs across the front and a Rythmik FV15HP.

Something is very wrong.

I ran Audessey MultEQ. It set my front speakers to large and turned on a setting called double bass. I crossed them over at 80 instead. I tweaked the levels just slightly with a db meter (Audessey got pretty close) and ran the sub about 3 db hotter than the rest.

I ran a few movie scenes and songs -- very weak output at best. It makes my old Klipsch RW-12D sound like a monster. And that's not just from my listening position -- that's sitting right in front of the sub. I haven't gotten a chance to do a sub crawl or experiment with position yet.

I watched a bit of Black Hawk Down (5.1 on Netflix) and listened to Bass, I Love You (Spotify) and the sub was definitely on, but it was not good. On Bass, I Love You, the driver moves a lot but either produces very little sound or feel or even worse makes a farting/flapping sound.

I'm not ready to pack it up and send it back yet -- but what might be going on?

Doesn't setting the satellites to "Large" direct bass away from the sub? Try setting them to small. (even if they're not)

I did -- there's no small setting in my receiver, but when you apply a crossover of any sort (I set it to 80), you change from large to 80 and the speakers are set to small even though the receiver doesn't explicitly use that language.

What is the subwoofer level trim reported from Audessey?
Please download the installation guide at FV15_FV15HP_PEQ3_Installation_Guide.pdf if we didn't include that in the package. Please also make sure the rumble filter setting matches the number of ports being used. For instance, use ON/2 for two ports open and OFF/1 for one port open.

I ran Audessey with the sub volume at 50% and it set the sub level to +0.5 (I think -- it was really close to 0 -- I boosted it to 3.5 I think).

The sub did come with a manual. I left the settings as they were -- one port is plugged and the rumble filter is set to OFF/1.

Couple of good bass scenes I enjoy are when Souron is defeated in the beginning of the Fellowship also in I Robot when Sonny is captured outside the NS-5 robotics plant near the beginning.

Klipsch RW-12D does not hold a candle to what is in your room. Your issues are configuration. turn double bass off.

Process to verify your sub is redonk
level match subs to mains with no audyssey. turn volume to 0, play bass I love you.

EDIT: mains - small, crossover - 80 Hzish

That's exactly how it's set -- small/80Hz crossover (double bass is automatically disabled when a crossover is set).

I level matched the sub and mains using a DB meter and boosted the sub a few dbs in the receiver.

I've tried it with Audyssey on and off -- no difference.

FV12 ported owner since 8/31/11. Very Happy, for my small APT use. If anyone plays CoD, this one game type - called sticks and stones. The constant explosions just put a grin on my face (http://www.youtube.com/watch?v=bbzUTg8gVAk) it will put your subwoofer on a good work out haha

I see its out of stock now. The FV15HP looks good great upgrade hehe. What a monster!

Hmmm, I may have misinterpreted "I ran Audessey MultEQ. It set my front speakers to large and turned on a setting called double bass. I crossed them over at 80 instead. I tweaked the levels just slightly with a db meter (Audessey got pretty close) and ran the sub about 3 db hotter than the rest."

Definitely respond to Brian / Rythmik reply. They are smarter than me. What are your mains and what is your AVR? I stand by the Klipsh doesn't hold a candle to your sub though.

I, also, have experienced the "lack of output" when you first fire up the sub. After talking to Brian, I am convinced it was just due to the sub not being broken in yet, and the spider/surround needing some exercise. After a day or two, the sub started sounding much better!
post #7950 of 15160
I would implore people to not underestimate the effect of being out-of-phase with the mains has on the impact of the bass.. not to mention that auto-calibrations are not always optimal.
