Got another addition to the family today.

I have all winter to build these...so its time to ponder enclosure ideas.

Building into 12"s.

Going in the trunk of a 04' Grand Prix

Thinking of allocating about 5 cubes to L port.

Box can be deep as long as its not over 15 " tall.

Was also thinking if a 4th order would be worth it, but its very hard to find info on successful sealed builds with these, So I'm taking a shot in the dark.

Sub forward port forward may not fit across very well. It will be tight. But probably would work. They are very heavy drivers however, and would like to have space for bracing.

Was maybe thinking aero port to driver side, or..

really want to load them off the trunk though. ugh

Great motors...

Spam

WTF!!! Spammer be gone

lol ^ trying to get post count up?

Might wait to run both.

Not sure if my car will be able to handle the weight.

F that I'll build. seal off. listen. repeat.

You trying to get your post count up by posting that?

 What is the depth and length dimensions you have to work with? I would recommend firing drivers and port to the plate..And would not go less than 80 Sq inches of port area..And tunning @35HZ..

Depending on whatever softparts you choose, the original specs had a higher overall Q.  They work well 4th order vented, but the box needs to be a little larger and tuned a little lower to get a flat response.  No big deal if you have the space...  Arbitrarily choosing a vent area without modeling is kind of pointless, you may need less than you think making box design easier or you may need more to keep compression down and it may cause you to re-evaluate you design...

 

They do have a really flat response sealed and don't require a very large box to get low with cabin gain, BUT they aren't efficient drivers to start with and going sealed is going to cost you some output...

Thanks for the input.

You trying to get your post count up by posting that?

and yes I am.

Thinking of building a box outside of trunk and sealing it to the frame leading to the back seats.

Can't be more than 34" wide and 14 tall to accommodate fitting it in from back.

I hope I have enough width to give it port.

And I would probably tune @ 30 with 75-80 sq inches of port.

In no way am I trying to be efficient, put up numbers, exc.

I will use a dual stiff spider on these and be over powering them a bit.

Curios on why you would tune these around 30Hz ?

Again, it has nothing to do with "chasing numbers" it is about optimizing what you have.  If you get OE style softparts you will know what the T/S parameters are and you can design a proper enclosure.  If you get a stiffer suspension set up than intended because you want greater mechanical power handling, you are going to raise the Fs and lower the Vas, both decreasing low end extension and efficiency.  

yes, understood.

 

I went with OEM coil and suspension.  Just ordered my first recone, on top of a frame, enough glue, and the dish dustcaps with original XXX logos Dave had laying around =]

 

Still need a battery and another run of 1/0.

 

Going to start planning the trunk wall..can't wait until I get my tax refund.
