You want the DBK-212 for the 12" driver and home use. The Death box-II could could be scaled up for a 12" driver, but I recommend using the DBK212 plans on the site first.

Your second link was no good, can you fix the link?

Bob and Shreekanth thanks for the replies.

@Bob

I was able to find the plans here only for the 10 inch driver model(dbk10). I did not find the link for the 12 inch model. Can some one PM me the same....

The first link is for Pioneer TS-W307D4 model driver
The second one is for the Sony XS-LP121P 1200 model driver.

@Shreekanth

I am from Hyderabad. Can you please PM me your yahoo/Gtalk id so that we can chat on the same......I would have requested the same through PM, but I don;t have 5 posts here to send a PM and I don't wanna spam others threads

thanks

Here is the link to the DBK-212
https://www.decware.com/newsite/dbk12.htm

I think your thinking it is in with the DBK-10 plans its a completely different cabinet.

I built my DB II today.. Satisfactory results already...
But the mistake I did is I made Y shape vent, instead of D shape....

I actually did not understood the marking given on the Panel D about the D vent.

Is the marking X/Y inch is the height and the Diameter respectively for the D? or does it mean something else?

some one please reply, I will modify my DBII.

thanks

Thenvk,

If you are building a deathbox with the "D" shaped port you are building the 10" version, no? the 12" version has the bell shaped port.

Or am I missing someting?

He is building the DB 10", so he has to work on the "half moon" area 8-)

Thanks Shreekant...I thought I was loosing it, whats new right?

I was trying to post the formula but couldn't figure out how, the radius of the arc is 4" not exact but close enough.
