My sealed RL-P18


At last the box is almost ready. I only need to do the finishing touches (which I don't
have the patience to do... )
My first plan was to go vented (about 350-400 liters) but after I saw the big tube in my
room, I changed my mind and went on a small sealed box (about 110 liters). four times
smaller, but without the really deep stuff ( if I had a house with a basement I would
have went the LLT way, but I don't ).
Since this was my first go with a wood router I made a few mistakes, tried two different
routers and also did the outer circles with a jigsaw. my first go for a 43.2cm driver cutout
was a disaster and the cutout was too big . the second one was ok and actually smaller
then the "official" 43.2cm, however it was still bigger the the needed cutout. maybe it
just isn't 43.2cm...
My rl-p came with a loose rubber frame, which made the mounting very hard. I tried
without the frame, but then there were too many air leaks, and after a small effort I
managed to mount the driver with the frame.
Included are measurment before & after EQ in my room (4.5x3x2.7 meters) using REW
and the behringer. The amplifier I'm using now is the buttkicker amp, which in time I will
hopefully upgrade
After a small listening session the new sub is definitely more potent than my previous
sub ( a ported Shiva ). however since I have neighbors, I can't pump the volume anyway
