I'm going to get my teeth capped, but I am wondering what do those of you that have heard the Brahma ported, think this will do? I am primarily focused on SQ. I was just hoping for some more low end extension. Also, I feel due to cabin gains I will have to deal with the low end a bit. Should I use the HU EQ or just play some with an inline?
If you port it, tune it low. That will keep the SQ for you. You'll get a lot more output from the driver down deep. As far as EQ goes, if you want to get serious about it get a good EQ, like the AudioControl EQT or equivalent. A band or two really aren't enough to do much with, other than just bump the bass or treble. For serious smoothing, get a good 1/3rd octave EQ or a nice 5 band parametric. Dan Wiggins Adire Audio
That sounds real nice sandt.... I wish I could hear it Im thinking of a very similar setup with about 3-3.5 cubes and tuned to 24 Hz
sandt according to winisd ported at 30hz you should be up around 8db more than sealed at 40hz its going to be about 4db louder
I'm all SQ. I'm looking to create a deeper, smoother low end extention. I will not port over 24 Hz... Spl is really a non issue. Take a look at it at 2 feet tuned to 24Hz, with 20Sq in of port area.
no sandt there is no spike should i say it in reverese sealed box is DOWN 8 db at 30hz and DOWN 4db at 40hz the ported curve i have is nearly horizontal at 0db from 30hz its up about .8db until 55hz it should sound very good ported should sound better than sealed in this case at least thats what i get, itl depend a bit on cabin gain Last edited by Krelkor at Nov 3 2002, 04:06 PM
Cabin gain is part of my consideration here K. I want to do as little EQing as possible. I did my measurements and I came up with enough space for the enclosure to be 1.9 feet, tuned to 24Hz, with 20Sq inches of port area. I know, I would like more but that is all I can manage.I will use external ports to aid in bracing, and some threaded rod for bracing as well. I will put it in the same location as the current, and it will be inverted. In the big open spot I will be doing something a bit different. I will paint the enclosure a high gloss white, and I will cut the Brahma logo out of the carpet, alowing the white to show through on the enclosure. I may accent it with some blacklight, but I am not sure. I don't want to get too cheesy. The rest of the install will not change, aside from the things I did yesterday. I will also add a fill panel to the left side, near the trunk hinge, and a carpeted cover over the battery case to eliminate the eyesore really only apparent in pictures for some reason. The box will fill the open space you see below...
Oh, wait. I see what you are refering to K. Don't look the the SPL graph. Look at the TFM, and Group delay. Look at both the 30Hz, and 20Hz tuning. You will see the peaks lower within useable frequency range. More indicative of a more SQ based enclosure. SPL is of NO real concern to me. I know it will be louder than the sealed application, and the sealed application is too loud for me right now. I will tame the gains considerably for this enclosure, I assure you
