turn loudness off... no matter what you think, turn it off. its only meant to be used on low volumes Why at 125hz? How about 80/100hz instead, cant imagine the subs enjoy playing that high. Sub level should be at 0. When I had that unit I could go 38 clean. Last few volume clicks accounted for more than 1volt of signal. reset everything with EQ flat, no bass boost, using -5dB or -10dB. you might have been used to a lot of clipping with your previous setup.

it IS a 4v headunit, thats not the issue. again, what are all your settings on the headunit

I see you have 4 subs with 3 homeade aeros...were the two directly under the port the 2 that aren't working?

Ive owned the mvh... what are the settings/volume you are using

pic of box? box specs? amp? sorry I'm unfamiliar with your build.

so they still work with no scratching noise, just read higher than expected on DMM?

Tinsels "messed up"? The only thing they will do is rip off from over-excursion, in which case there would be no resistance because you aren't completing a circuit. DMM would read nothing. Rare occasions they burn up from too much current (amperage) but I haven't seen too many of those. They would be discolored with a yellow to brown color.

anything dubstep/techno will peak around that range sucks you peak so high, kinda limits you to songs with kick drums and bass guitars

Won't know til you rip it apart. Might have had too much current, melted the lead wire first into the windings and it re-welded itself back, but with higher resistance. Just had that happen with a dc lvl5, coil was absolutely perfect except for the exact part where the lead goings into the windings. The sub would play/put amp into protect randomly but sounded terrible. Gas expanded from enamel heating up too fast and bulged the former causing the sound. Coils would read high 5s to 6ohm on one side, the other read ~.8ohm like it should have.

the picture above is a great example of how the mids/disappear during the loudest part of the kick drum. You can also see how the flat plateau is pretty long in duration... that is what you want to avoid. Notice how its not red and doesnt surpass 0dB, but those flat spots are what will warm up coils/amps faster than the wavelength below it... even if the waveform below is louder.

Examples of purposeful distortion would be "North Pole" or "In Love With A White Girl" An easy way to distinguish is fine the peak in audacity and generate a sine wave of that frequency. Listen to the pure clean sine wave, then listen to the song with the same note and you should be able to hear the difference. Even order harmonics(2f, 4f, 6f) add a warmth and usually pleasant matching quality whereas odd order harmonics sound misplaced, going against the grain or unsettling sounding. Tube amps are notorious for adding even order harmonics...often people say the sound of tubes amps is more natural and live sounding. So harmonics arent always a bad thing, but when u have low bass notes and the 2f falls within the subs passband(between subsonic and lpf) you get a rather unpleasant sound compared to a clean note. Most of rock has distortion, i mean comeon... they use a distortion pedal, lol. Dubstep mids are notoriously harmonic and can really give ur mids a workout. Most of distortion from sub bass can show up in the mids spectrum but can be masked by the sub trying to produce the same notes.

Ofcourse you can attempt to do that, but placing sine waves ontop of all the mids/highs is no easy task without finding each beat, 4 count, etc. you need something to base timing on. In audacity its very difficult to properly time the notes down to the millsecond. The above member has it correct that the mids/highs ride the bass lines. Picture the usuable data range of music as an ocean but with a ceiling at 30ft. If there are surfers(mids/highs) riding big waves they are fine as long as they dont go above the ceiling... once they get pushed into the ceiling you can never recover the lost body parts pushed outside the cieling. So yes you can remove the problematic waveform, but the distortion present from clipping will remain. Lets say you have a 30hz note with 2f and 3f distortion from clipping, or even just that the artist wanted that sound(lex luger for instance) and you highpassfilter it at 80hz... because the filter is sloped some of the 60hz will reside and all of the 90hz with reside with the mids/highs. So then you spend about 30min-60min adding in proper sinewaves only to combine them and it still sounds odd.... that is the remaining distortion you could not remove. The solution is to use higher crossover points but then that degrades balance if instruments were located within the filter slope. Lastly, if a song clips its not just the bass affected, any note during the surpassing of 0dB is affected. You can also have distortion/flat bass lines below 0dB, which is why Audacity's "show clipping" is not the best indicator of detrimental clipping. I'm at work now but i can post pics when I'm home to visual what I'm explaining

Music will always be recorded at different levels, that's why bass heads seek out the loudest songs. (this is why apple has the "check volume" feature, to lower all musics level so there less of a difference from quiet to loud songs. again, "check volume" will lower the overall volumes) The CD should be 1411kbps, so anytime you "Rip" it besides Apple Lossless/FLAC/WAV you are lowering quality, albeit a test tone. 320kbps mp3 is fine for everything, most cannot even tell the difference from 192kbps to 320kbps, the largest difference with be the subtle nuances present in the upper frequencies. I'm not sure whats going on but you shouldn't be able to up the quality, that makes no sense. you cannot create more data, you can only downgrade the quality. regardless what the program above does. If you plan on using a digital device I would download the tone from the website, or have a trusted individual make one in whatever format you want. I recommend ripping in 320/256kbps mp3, its the most versatile format and very few will notice the difference from CD quality. If you have bass blasting shaking your car to pieces you arent going to notice the difference, unless the CD source is louder than the IPOD/USB/SD/AUX source.

LOL@Kranny Just because you have more power going to a sub doesn't mean you can keep shrinking the volume and the power magically makes up for the completely different box characteristics. 100w over rms is nothing because. The above box is fine, stick with the 3cuft you have and don't forget to add any bracing displacement you have (will be minimal, a few dowel rods will be way less than .1cuft)

yes that site is legal finally got around to listening to this mixtape... sucks and won't make your subbies happy

nothing to bass boost, its already -6db each kick drum and the highs are already pushed past 0db throughout most of the song (typical with most dubstep)

this is the difference0dB for headunit/least distortion -5dB for amp gains/sq setting << what i use -10dB for amp gain/compromise << what most use -15dB for amp gain/spl setting << too quiet for rap music max would be volume 34 in this case

pianoroll on FruityLoops

color of fabric changes with the light Ill take pics of current install tomorrow

no they are rated @13.8v and you will only see 5600@1ohm if you wire low (.35-.5ohm) with very little impedance rise says this online and in the manual "Rated power([email protected]) BC2000 2150@1ohm 1100@2ohm BC3500 3875@1ohm 1950@2ohm BC5500 5600@1ohm 2700@2ohm"

saz1500 input side rebuild db-r received 1/16 i received amp back 2/02

yeah you shouldn't smell the amps, lol

zoom in, you cannot judge by the pic shown. did you rip it from youtube kranny? i just ripped it, its clean enough, my ears were just hearing the 44hz/88hz notes played at the same time, though it was worse distortion than it is. my copy looks like this

how warm is warm, do u have an infrared? -5dB is the first option for music, 0dB technically would be the safest but also the quietest... only test tones for burping are that loud
