If your always adjusting your subwoofer volume look here :)

[60ndown]

or maybe this is just another DIYMA 12 thread?

i have always adjusted the volume of my subwoofer depending on the track i am listening too, i listen to a lot of random mp3 ranging from reggae-death metal-rap-country .

well today, i took one of my DIYMA 12s and put it in a TINY box (13"x13"x4" approx?) inverted, and took it to my front room to compare it to my 'sonotube' DIYMA 12 (about 4 cubit feet, my attempt at I.B.kinda) that ive been listening to for a couple months.

i put a typical random mix on and began to cook dinner, after 20 minutes i realized i hadn't adjusted the sub level at all? i had too keep poking my head round the corner to listen more intently to the music because everything was sounding so 'articulate' tracks i would typically 'skip' were enjoyable?

i only have 2 ideas about whats going on,

1.The DIYMA is wasted in a car enviroment, in a tiny box at home its simply stunning!

2.I MUCH prefer very small sealed boxes (critically damped?) qtc .5? im still confused about the terminology even after that classic thread.

ive NEVER left my sub volume alone for more than a couple tracks, home or car. havent touched it in an hour and a half? everything sounds amazing, nothing is missing?

my have to cut the box for the arrrrgghhhh down from 2.5 to 1.3 .....and soon

if your always tweaking your sub volume, and you think (like i did) that it was the 'different production' on various material, i sujjest you get your moofas into a much smaller box.

ive sat in multiple cars where the owner never reached for the sub level controller regardless of what we were demoing, i always wondered why they didnt need to?

now i know, they use small sealed boxes.

or the DIYMA 12 is just THAT GOOD.

What I have always done in order to tune the low end, is to simply grab a very well recorded disc I am intimately familiar with how it sounds on my home rig, and other systems, one that gives the subs and lower mid bass a good workout. I do whatever EQ'ing and final knob twisting necessary to replicate it in the car.

My feeling is, if it's right as rain on that recording, then I'll be hearing whatever is on EVERY recording, good or bad. I do this for the entire frequency range. That way I don't go crazy chasing the holy grail on each and every CD.....just a precious few of them.

The unfortunate thing in our passion is that the more resolute our systems are, the easier you'll be able to detect the sorry sounding recordings out there.....and there are a LOT of them at large.

If you begin to attempt to futz with the EQ to make these bad recordings passable, you'll unfortunately not be getting the most out of the good ones that ARE out there.

Actually critically damped (.5QTC) is a larger box. The smaller the box, the higher the QTC is. You probably mean you prefer overly damped.

I RARELY adjust the sub and honestly play with everything else maybe 2-3 times per year! Yeah, when the windows go down and i want to romp on it I'll give it a twist but that's it!

Tell us more Lashonda, where is the sub in the room, corner, against a wall, etc? How much power are you giving it.

I'm itching to try a DIYMA and you have put it in everything from a paper towel tube to the titanic.

[GlasSman]

Shit I might try one ....or two in a paper towel tube.

2 DIYMA's and a Titanic 12 in the back for LFE.

I would think that you are enjoying the benefits of having it in a better listening environment vs. the size of the enclosure, personally.

600sqft L shaped room, subs in the corner of the L

all the above are approximate.

[60ndown]

basically ive gone from a huge box, 4 cubes, to a tiny one, .3 cubes?.

thats the only difference. i figured all the low end would go but it hasnt at all, things are just way more accurate.

You are corner loading that sub like asshole is going to put flares on the WO I'll bet it does well if you feed it well.

[Andy Wehmeyer]

If you're adjusting the bass all the time in the car, that's a signal that the frequency response isn't flat. There's a peak somewhere that is energized differently with different music. In the room, there's less reinforcement between 30 and 60Hz and similar reinforcement below 30Hz, although there will be less boost at those low frequencies.

Sounds like a parametric EQ in the car and some tuning will fix the problem.

I've already bought the flares

As far as cornerloading in a car goes....stick with the tweeters

I agree, but some people just like to fiddle with the bass knob.

I got rid of mine.
