Thanks TOLMACH,

10 liters is what I need to put an I6SW in a ported box, the advantage of a smaller woofer is installation, the But of the Peerless 830452 10" XLS is bigger.

But that's for posting this woofer looks like a great option for Yaris enthusiasts looking for a good and smaller box solution.

There will obviously be a difference beteen an IDQ 12 and a Hybrid 6 (even if it's ported). I would seriously look at the direction of "fire" on the woofer before makiing permanent changes.

You have to remember that the mid bass shouldn't be affected when your final plan is put into place. look at the difference in the enclosure of the IDQ and the Imagine woofer. You also should consider the tuning frequency of the sub woofer along with the resonant frequency of the car...and correspond the two so that they work together. At what point does your vehicle sound the loudest bass-wise? That will give you a VERY good enclosure and environment to allow the sub to play LOW and loud without even stressing the amplifier one bit.

I agree 110% with you.

I asume the IDQ out performs the little I6SW (a 12" woofer vs a 6" woofer?), but I'm aware that I'm not pushing the IDQ, I've seen videos and they move! mine moves just a little bit, my gains are very low, I never had the amp even warm up after one and a half our of playing continuously all kinds of music, the volt meter in the P99 shows 14.1v most of the time on the road, and at stop signs around 13.8v with music playing all the time.

I had a time of my life where I wanted my neighbors and friends to notice, hear and feel when I has coming around the corner (and I did, but boy my ears hurt and I really didn't enjoy music as I do with this set up), now it's all about sound quality, and it's just that little touch of bass (true bass) what I'm looking for. Low to moderate volume it's what I like, feel the music, be able to drive for more than an hour without fatigue or a piiiiiiiip inside my ears. I enjoy all the benefits of the time I spent deadening my noisy Yaris.

That is why I appreciate all your help, it's a learning process, it's an art, obsession and passion. After experimenting with the woofer up front there is no way back, it just sounds and feels beautiful (at least for me).

If I end up going with a vented box with a I6SW I know that it's the "vent" direction that counts, and maybe I'll to a dummy enclosure (ends up about a little bigger than a shoe box) and just play with "direction of fire" before glassing any permanent installation. I know there are many other issues to take in consideration, but I'm willing to go ahead, learn and experiment and like my mids... you told me in a very nice way not to aim them like I did, now I'm going back to re-aim and play more "off axis", but how I know this is the way to go... by experience! I learn from my mistakes.

Now I'm stuck with a problem at home.... "no heat!" I got to fix that first.

I'm trying to understand... is this the point where the bass sounds better at a specific volume level...

I would say if 1 is really low volume and 10 is super loud without distortion... the best is from 4 to 8 and some thing I found is that I really don't make gain adjustments on my remote any more between songs, the bass sounds great for all kinds of music at any volume level.

Some thing I found very nice, before I had to adjust one, two or tree clicks on the gain control, depending on the song to make it sound good.

Please correct me if I'm wrong with this question.

Okay...let's try this. Do you have a sine sweep from 100 to 20 Hz?

I'm working with a couple formulas to try to figure out what we can do with the ol kentucky resonator design on this woofer...

I'm working with one of the guys on the team who is actually fabbing up a ported enclosure to send it to Scott.

Yes I do!

I got these bunch of Test Tones, that I have no idea how to use them, I got them from AmpGuts.com

If you can find a 100hz to 20 hz sweep and burn it onto a disc...that would be good. Also, see if you can find the tones from oh, 36 hz to 50 hz in half dB increments... Burn those onto the disc as well. Something tells me we'll find the sweet spot inthe sedan around 38 to 42 hz.

Done!

what do I do now? just play them? what to expect? what m I looking for?


Thanks

[sqcomp]

what you're looking for is the frequency that sounds the loudest in the car. You're going to work the sine sweep until you get the general idea of where it sounds the loudest and THEN work the half dB tones until you nail it down specifically.

From there we tune the vented enclosure to work WITH the natural frequency of the vehicle to extend the "bump" of the overall response in the vehicle.

Thoughts?

OK,

Let me try in my way home. I'll let you know.


Thanks again

[derickveliz2]

OK, this thing it's hard for me, if I'm doing correctly it gets louder between 30Hz and 50Hz

Should I be looking at the graphic EQ display?

Sounds pretty good from start to end (feels good too). With a little low some where around 63Hz I guess this gap will be fixed once I install the L6s.



D.

[sqcomp]

The deck's display won't give you any pertinent info. At least we've nailed down the 20 Hz range. Now it's nailing the specific frequency to tune with. Is there one o those frequencies that "moves" the car more than the others?

...you probably also noticed that the Voltage likes to sink when throwing out sine sweeps...

I'M GETTING THERE!

In idle yes, and I haven't tried with the motor shut down; at highway speeds not much.


PS... I finished my taxes.... need to talk to your buddy... I need rings and a I6SW

D.

[sickpuppy1]

I hope you meant you need to talk to his buddy, lol

[sqcomp]

I remember the pricing for the i6sw...drop me an e mail of the time frame that you want this to happen with the woofer and the trim ring. I'll let Jim know...

See what happens when you post around 2am LOL
Zzzzzzzzzzzz

LOL, I figured as much. I just have a habit of pouncing on a weak moment. Its a short guy attitude thing.....

[derickveliz2]

Well,
I've been looking for a new job, there is one that may work out, we'll see.

In the last week I've been struggling with some tire noise from my snow tires, what caused the noise? you got it! the rear Camber kit I installed last Fall.

So after figuring out now I'm going to remove the camber kit, it's a pain but I rather have a quite ride than a good looking camber wheels.
