Ok its taken me quite awhile to get into this forum, but here I am. I have already built some of the boxes here (2 DB10s, the Wedge, and  a HW). My question is....I have a DB10 with a pretty massive 10 in it, I am extremely happy with it, so next project is either  2 DB12s with cheap subs or another DB10 and go and buy another sub? I have 2 cheap 12s, and would like a pair instead of a single sub because of imaging problems. My DB10 dominates the room. I have it in the corner, port facing back, but still a little to much highs out of it. I really dont see how 2 of the DB12s with cheap subs is going to keep up with the one I have.

two different subs in the same room in different locations would be a nightmare to make them sound good together...stick with the the same subs in one location

x it over @ 60, maybe turn it down a lil, and maybe move the insert down also.


you could build a db 12 with the 2 cheesey subs 'clamshelled' ?

thanks for the support all.....I been visiting this site for quite some time now. I have built the wedge and installed it in a 03 mustang...it wasnt a spl sound, but oh the low bass. I strive for the low end when it comes to building a system. I been putting together car audio systems for...well not quite the 8-track days, but I did have one. Steve has quite a few nice designs here, if only I had access to this site years ago.

This thread could very well be dead already- but I would vote for 2 DB12s vs. 1 DB10.  I love the DB10 when compared to a DB12- but 2 DB12s is an awesome setup.  Anytime I can do 2 subs in a room- or even a car- I always try.  The increase in displacement (usually- although a good 10 vs 2 crappy 12s may not be quite so big or might not even exsist.) and the ability to place 2 subs to better fill a room makes it a no brainer to me.

If you are deciding on building 2 more DB12s for the 12" Subs you already own vs. purchasing another 10. I would build and try the 2 12s.  The 12s tend to dig lower and 2 subs can usually fill a room better then 1.


XO point is definately something that varies greatly from install to install, but I never like a sub XO above 100HZ 12db/Octave. (80Hz 6dB/Octave is usually my favorite in home) I just can't stand the honkyness higher XO points or shorter slopes allow through.
