How about this.. After subtracting the port volume I have 2.16 cubes minus the .16 for the sube im left with 2 cubes at 39.9Hz
heres what he said "2.25 @38 will keep him in the lows if he goes 2 cubes at 40 thee is a chance he may unload the woofer by going below tuning" and about the new numbers: "those numbers look good, if he is worried about size, the trend from what memphis suggest would be tighter box, higher tuning but he should be fine there"
Okay i gotta be honest.. Im kinda confused here.. Is the new set up okay or not?? he said 2 cubes at 40 may unload the woofer (IDK what that means TBH) but then he said the current numbers look good.. So are the new numbers good or bad??? Oh and for the people asking about the calculator im using here it is.. Torres' Box Tuning Calculator - SMD Forum Make sure to and .exe to the end when you save it.. or it wont work..
"the 2 cubes at 39 is good before he was at 2cube before displacement at 36hz which would have caused the sub to unload." I think he had a typo issue. So the new numbers are good.
Okay awesome.. Looks like im going with this then.. Tell your friend I appreciate the help.. Now I just gotta build it this weekend and hope I can cut it striaght enough with a skill saw.. Damn i need a table saw this weekend lol
Im glad this helped, i was just the translator/ copy paster i have no idea what any of this is. Good luck with the box
Well its lookin like I might not get it done this weekend.. Still having to work on this blazer.. Everytime I fix somthing somthing else goes wrong..
Hey, TLS, are you using any acoustic insulation within any of the chambers? If so, what kind, and how thick? Old school speaker cabinets (KLH, JBL, etc) merely added insulation on EVERY exposed interior wood panel, so you might need to account for the reduced volume within the enclosure. I've seen enough of the cheap pre-built MDF boxes, most that have inadequate insulation, and you get more rattle than deep bass. Not exactly what you want within the cab. Take your time, ensure good seals on the joints, and add a rubber strip where the speaker frame meets the wood. Good Luck!
BTW, I once went to one of those tool rental places, and got a nice sized table saw with 12" blade for $20 for the day. Will make an easy job of that MDF.
Well after 2 months I finally got around to doing this tonight.. Planned on taking more pics but my phone died.. Anyway its all put together.. its not perfect since all we had was a skill saw a jig saw and a drill but we got it together okay for what we had.. It was suppose to be 2.20 ft3 after all displacments and tuned to 38hz.. But due to a mistake on my part with the port I lost 3/4 inch of height which makes the box 2.10ft3 @ 39hz oh well still gotta be better than what I got.. Sent from my HTC Inspire 4G using Tapatalk
