Posted May 29, 200520 yr someone told me to drill ~1" hole in the back of my kick to "vent" it into the floor...would it be better to do this or to actually port in to a certain freq? and if ported is better, what should i tune it to?
May 29, 200520 yr hollow? like boomy? i'd suggest slugging it first, lower the volume a bit and see if that helps...if not, and u want to go ported, then port it (i guess..lol..85hz??) but port it, i wouldn't just "drill a 1" hole"...that'll defeat the purpose of having ur mids enclosed..i would think..wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

LOLbut hollow as in around 100-200Hz, it sounds like all these notes are being played in a bathroom or something. its kinda like.....BOOM(echo,echo) see what i'm saying i was thinking maybe stuffing it full of some polyfill, might tone down the echo some....would you agree or disagree.

May 29, 200520 yr The only time I've seen ported kicks was in a kicker SQ car. The kicks were ported with a toilet paper roll he said. Said he could change the tuning by adding or removing some of the length of the roll. Makes sense.
May 29, 200520 yr aperiodic enclosure Actually been known to improve midbass response. Trying to find the article I read once about it.Also...Remember in the previous articles that enclosure resonation and standing waves destroy good sound quality. You should keep this in mind during construction. Make the baffles as solid as possible, make the enclosure walls thick enough to avoid flexing, and make sure the kicks can be very securely mounted to the car. Damping the kicks during installation is a very good idea (as discussed previously), and the use of DeFlex pads or polyfill will help control the standing waves and reflections inside the kicks. Even a form of absorptive damping material can help dramatically.
May 29, 200520 yr Found it:We have already gotten a handle on #1, will address #2 more vividly in the Tuning section but proper fabrication already has us on-track, and here is what I do for #3. Since my kicks use a floor mold, which is made to rest right on top of the vehicle

May 30, 200520 yr neon, thanks for the link...what if a person has rubber floors? (my bro-in-laws silverado has a rubber floor mat thru out the truck, no carpet)anyway...thanks for pointing jelly in the right direction..i stand corrected....wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
May 30, 200520 yr I personally feel it's a resonance isssue. I'd go to a habby store and get some modeling clay first and start packing that baby till it sounds better.

May 31, 200520 yr Resonance doesn't always mean flexing. Your kicks are probably a tad big, and the resonant frequency is high. Dampening material would help more than the hole I think.
May 31, 200520 yr Resonance doesn't always mean flexing. Your kicks are probably a tad big, and the resonant frequency is high. Dampening material would help more than the hole I think.Well put, and agreed. Simple vibration from electrical current can cause resonance. I have had several times where I actually had to add mass to the frame of the driver as the basket was resonating. I now practice this on all smaller drivers just as a precautionary measure.

I now practice this on all smaller drivers just as a precautionary measure.<{POST_SNAPBACK}>how big should kicks be???what kind of dampening material? what do you add mass to the frame w/?i do have another question off the subject...how do you adjust your eq? i got the 13 band on the h/u and i find myself constently adjusting it. sometimes it sounds good sometimes it don't...but i can never find that perfect spot where everything just sounds perfect. the BBE feature on the h/u...on or off? sometimes it makes stuff sound better, sometimes the highs just drown everything out.
May 31, 200520 yr I put the BBE onYou should be able to adjust it on a number ratingNo 2 songs will sound the samesome will be harsh some wont
May 31, 200520 yr Well, it's kinda hard to answer your questions really. When I build kicks, I generally build the enlosure to suit either:A. the flattest responseB. the best response throughout the specified frequency range.If you don't need a driver to produce XX.xxx frequency, why make an enclosure that will. Now this is easier said than done, and most likely just complicates things even more, so I suggest a simple modeling program like winISD or BassBox to get a general idea. Or simply calling the manufacturer.As for tuning the best way IMO is to use your ear. That's going to be the judge in the end I myself try to start out flat, so if I have access to an RTA and a mic, I will take advantage of it. Then I'll adjust from there. Everyone's taste will vary though. ME, I can easily do without a subwoofer and actually rarely use one nowadays. I like a very STRONG,almost overbearing midbass. Take it how you will, but the best way to do it is to just keep playing until you're happy
May 31, 200520 yr Almost forgot, I usually am very partial to the modeling clay for everything as it will conform to ANY shape, sticks in place and will add quite a bit of mass. And it's CHEAP.
May 31, 200520 yr funny..i suggested he lower the internal volume in the very first reply..noone agreed with me. of course i didn't use $3 words to describe what i was talking about.....i guess noone reads my posts anymore... bastages....wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
May 31, 200520 yr Author How does one go about adding this clay ?<{POST_SNAPBACK}>i believe you just press it against the wall. its kinda like silly putty...
June 1, 200520 yr Kent, noone disagreed with you either. MAtter of fact, the clay thing just happens to take up some space as a side effect. Hell, I don't even know if it is resonance, it was just a guess as I've had this exact same problem a couple times already myself.As for applying the clay, you are correct. Don't be afraid to try some on the frame of the dirver as well.
