Fric Epic-urious build thread! People have cried...

I get paid as an Ironworker. But what I do usually depends on what type of tool is in my hands.

congrats on the new job.

this build is a blast to follow.

Thanks man! It'll be sad when it's over. LoL

 

[WOOSEY]

This will never be over... :P

progress?

progress?

good question. people have stopped crying.

Well I got tired of posting redundant boring tuning posts and I don't have any new photos or work done.

But if y'all want to know the tuning is going well. I've finally got good left/right/center definition while maintaining the tonality I like. Now I'm hunting after more depth and better resolution across the stage, in between left and right.

I think a limited stage width will be something in just gonna have to live with in the current configuration.

Well I just wrapped up a complete retune (about 3 hours).
The goal was to create more midbass impact while retaining stage image and upfront bass.

Nail. Head. Hit!
I achieved this through a combination of research and knowledge of acoustical theories, careful planning and measurements, and much trial and error (and LOTS of help from many of you clever gents). Every time I retune, I dial it in a bit tighter!

This time I even managed to improve naturalness, tonality, and depth! I'm a happy camper!

I'd also like to add that I started by trying to get my frequency response as flat as possible by just using clever crossover point and slopes and gain setting. That way non of my parametric eq bands were waisted on crossover gaps or driver capabilities. I wanted all if the bi-quad filters to be directed towards frequency response issues related to the acoustic space. It worked out quite well!

Also, everyone has been bustin my chops about a midbass needing the polarity reversed. Every time I mention a lack of impact that the response I get. Well a few people gave me the advice of raising my crossover point to clean up my midbass and let the subs do some of the work. Well this worked like a charm and I managed to retain my upfront bass by trying different slopes. I'm currently using 18db BW filters on my L8's HP and a 12db BW on the LP. My mids are HP'ed with a 24db LR filter.
And as it turns out my entire stage was inside out! What I thought was a decent image was messy and wide. I reversed polarity on the passenger side full range and everything tightened up. It's like my left and right are earphones and the car is my head. Saying my stage was inside out is the best way I can put it. I'm sure you guys know what I'm talking about.

So I had my amp clamped and Pyle subs metered. With my gains cut back the amp metered at 560 watts with around a 2ohm rise.
The subs peaked with 138.5db @ 25hz!

Not bad for $120 worth of speaker in IB on less than 600 watts.

25Hz, that's low! I bet the whole car rumbles. Was that measured with a sweep?

 

[Fricasseekid]

No. I used a tone generator of an RTA app on my phone.
