I understand,

"do what ever it takes so it sounds right"

and like I wrote once... everybody hears different.


My observation when I had my tweeters crossing low, is that it was harder to adjust center image due to reflexions from the windshield and matching with center image on Mids, going back to point source (with Mids) made my tuning easier, sqcomp knows what he is doing for sure and with a purpose. Some times I like the easy way.

But that's just me.

I have a question...with active filter...and 75W of output on the L1V2...do you need protection ?...75W seems a lot for those little tweeter :S

[_S7V7N_]

Tolmach I hope you're getting more info for that reply you just gave if not it was totally pointless. The guy can't just go and start cranking on dials and everything magically sound good. If I'm right he has 5V preouts we will need to see the input sensitivity on the amp he gets if it's 5V at the min position you have to be very careful with gain. We need a lot more info before we can give advice.

Packet please don't mess with any of your equipment until you fully understand how you are going to tune the amps and set you crossover points, eq's, we will get you a very detailed how to on setting your amp gain.

When that time comes we'll need detailed information on your equipment.

Clarification would probably read like this:

Adjusting the gain structure at the source and at the amplifier to not give off a clipped signal from the signal chain as well as a responsible crossover point for the tweeter is the way to go.

Think about it this way, Scott Buwalda is using a JL HD750/1 for each L3SE. He's not blowing speakers. I'm working with 240 Watts (@ 12V) on my L4SEs. I'm doing just fine. Why? Refer to the clarified sentence.

[sqcomp]

Oh! If I do change the pillar setup, I'll reuse these current pillars and do the entire pillar in ABS to reduce the stress points between the different substrate materials (plastic, fiberglass, filler, and MDF).

[derickveliz2]

Just to add more to the equation, I'm playing the I6SW a (Pmax Rated Power Input of 120 watts) with 400 watts. But Yes... I'm very conservative on volume, distortion and abusing speakers!

I know many people over power, but it's like Sqcomp's sample of the BMW vrs Prius, remember that?

Completely re aimed my front stage. Changed the crossover points and slopes. Now to get the pillars and kicks redone before June.

Tweeters or Mids?

D.

[sqcomp]

Yes to both. :)

It amazes me sometimes how far we come and yet how circular things are. I'm hearing that the tweeters aimed slightly into the glass are just a big winner for me. The issue I was having on the all pillar setup was left side width. With the mid below in the kick I have more width on that left side.

I'll have I e-mail you the camera shots of the placement where it sounded the best for me.

Yes! I'v been there! with tweeters it's hard with all the reflection either avoid them or play with them, my tweeters are kind of aiming towards the windshield.

For the Mid down on the left, I agree. Gives me more width that the a-pillar install and that's why I did the extra mile cutting the metal to push it as much as possible physically it's my speaker that sits farther to the left, both mids are off-axis but the left one has a slightly angle so if you see them from the pilots position they look almost to the same angle towards the listener.

My theory is that this way both drivers would give me the same off-axis response. I may be far away from a pro-install, but man sounds good!


BTW... I missed Why? for a "show off" we re-schedule for next week. That gives me time to start tuning each side individually like I stated a few posts above. Wish me luck. Will be waiting for that email, I'm curious to see how you end up aiming your mids and tweets now.

One of the challenges now is to find out what kind of plastic is used to make the a-pillars. I can't find an identifying mark on the back of either of my pillar sets...

Anyone have an idea? I'm hoping it's ABS.

This will help me figure out what I can use to meld plastic to plastic with...to make a new a-pillar entirely out of plastic.

[packetrace]

Someone already told me it was abs plastic...

[sqcomp]

If this is true then I'm set! I just became very excited. This means I already have experience with "cold molding" this type of plastic. Recall my conversion of the 2 DIN bezel into a 1 DIN for the P-01? *rubbing hands together*

This is very good!

...whoops...

I don't think I can stand up now! :P

[packetrace]

But verify to be sure but I remember someone told me this..:)

[sqcomp]

To update...I tore up the a-pillars:

















I know...it's rough looking...but it'll get there. It's all ABS so that means I can fill, shape, and mold with more ABS. Notice the ABS tube? It's already a perfect radius. You can presume what I'll be doing with that.

[derickveliz2]

Wow! that's nice, I can see how you are using the reflections of the windshield in your favor... that's what I call when you work with your enemy instead of fight it! (Spanish translation)

It came down to the center image. I was getting some funky phasing issues being on axis. I spent about 6 hours moving each set of speakers around, muting all the others, and searching for the center image. I found it. It turns out to be along the same aiming I had in my first iteration last year.

That's why I mentioned it coming full circle. The biggest difference is in the separation of the mids and tweeters. Still, even in the mids I have similar aiming as when they were in the pillars.

Some things are simply strange to me. I need to get this rocking. I have a USACi show on the 27th of May and on the 3rd of June. Then it's planning for a show at Streamline later in the year. D, I want to send you my ID8 in the enclosure I made for my wife's truck. I'm telling you, you'd LOVE the response from this little thing. This little thing is accurate...and downfiring?! It loads off the floor of the car and feels like you've got bass shakers in your seat without ANY slop whatsoever.

I'm sure the i6sw will give your ID8 some thing to talk about!

I just can't believe it's just a 6.5 inch woofer what I have.
