Graphs! 

 

i should learn how to interpret these some day.

Same here. I understand most of the terms, but have no idea how to interpret what I'm looking at.

[Quentin Jarrell 671]

very simple actually.  The bottom value is the coil's movement out being right, in being left and at rest in the middle.  let's use inductance as an example.

 

Go to zero X(MM) vertical line.  Again this is the resting position of the coil.  The vertical hash marks is the true resting point of the coil as it is being altered by the suspension. But we wont get into that at the moment.

 

All the parameters are calculated at zero X.

 

Le or inductance is listed at 3.2Mh in the list at the top.

 

So go back to the X(MM) vertical line and go to the point where the "curve" meets this line. And you get 3.2

 

Try it again and go to the 20mm out position and go up to where the curve hits that vertical line ~2.5mH.  This is the inductance when the coil has moved out to 20mm.

 

Do this for all the graphs and you can see how the parameters shift throughout the whole movement of the driver.

thanks for the explanation. I understand how to read the graphs for the most part but I dont know what conclusions to draw from them (ie. is the bl curve good or bad). I probably need to read a lot more on speaker design as well. I won't clutter your thread up with this, gl with the sub.

when inverting these subs, should the mounting diameter be enlarged slightly?

 

I see the hole should be 14 1/8"..  should it be enlarged to like 14 3/16" when inverted?

you just don't want the surround to hit.  It possible it might be a good idea to round over the baffle hole

[shizzzon 461]

Can you check and see if this is right-

 

If i remove the gasket on all the subs, is the outer diameter 15.375" (15 3/8")?

 

I'm pretty sure it is, but gotta know so i know which "route" to take

[Quentin Jarrell 671]

The gasket is 1/8 thick so yes it should be 15 3/8.  I'd remeasure one of the eight you have just to verify just in case of manufacturer variations

I did but with a tape measure.. I use the specs in sketckup to get my router point locations to a T

Im up loading somem pics for you now

This is a 12 but same concept applies.  It is a trim ring for my install to cover the mounting holes on the sub.  The ring is the same ID as the cut out for the sub same applies to the 15.

 

 

 

 

The have been routed with a 1/4 inch round over bit

 

 

 

You can see when the cone moves it actually pulls away from the ring.

Lost a few pics on the first post

I moved my folders around in photobucket. I guess the URL changed.

Hey Quentin, I'm designing an enclosure right now. Can you shoot me the specs or post them here so I can get some ideas of how I am going to do it?

 

Thanks!

Yea they disappeared. I will have the 15 back up and I finally have 12 results as well.
