There are several sick stereo installs here, I look forward to my install, but need to save some cash, and wait... 5 1/2 months.

not sure if i posted it, but old pic of my system

Nice pics!!!

Good stuff in here so far!!!! Hey GB, how often are you in Oly?

gravebox · 11-28-2009, 01:38 AM

^^not too often why?

update on system planning: sticking to the set of Peerless 830500's but going the passive radiator route and using a set of peerless 830548 passive radiators to go with it. makes for a REALLY small enclosure size, extension to about 18hz *just below the human hearing range* and will sound as if it was in a vented setup but without the vent noise and acoustic echo *flutter sound and muddy bass response*. with a little over an inch of linear excursion pure sub and only about 600watt of needed power shared between them it looks like i should be hitting mid to upper 120's and just barely scratching at 130 for a hifi sub system :P

^^^someone knows their $h!t..... omg!!

GB... I only ask because I'm in the Centralia/Chehalis area and would love the chance to gain some tips/tricks from someone who has them. How are you on speakerbox designs?

gravebox · 12-10-2009, 05:36 PM

i can design anything you want for any kind of application based on many different levels of needs

car, home, live, studio, club...
sealed, vented, isobaric, bandpass, horn, folded horn, passive radiator... it doesn't matter what it is.

Ok guys, i need some advice. Lets see if i can explain this ok..

I have 2 elemental design 10"s and a eD amp(ill have to look up what one..)

It sounds ok but not amazing, if i lean forward toward the steering wheel its crazy loud bass and you can really feel it, when you in a normal driving position its no where near that. Any ideas?

where do you have your speakers mounted and in what type of box? If you can move the box try facing the speakers towards the hatch or maybe even put some feet on the box and face them down. This will let them load up before you hear the bass and it might make it louder in your seating position.
My cars bass also get louder if I lean forward so thats not something out of the ordinary its loading up off the front window.
Hope this helps

actually, regardless of where you point / face the bass drivers, you will constantly be hearing the same thing while sitting in the front. bass is omni directional, which means regardless of where you put it, any signal from 90hz and down will be heard everywhere.

what you are hear when you lean forward is the spacing effect. while you sit back normally in your seat, you are listening to what would closest ressemble 1/2 space with the door window being the closest wall. when you lean forward, that would better ressemble 1/4 space which effectively doubles the bass specrum and increased the low end drop off. the small the spave factor, the louder it will "seem" to get. in a vehicle the spacing effect is actually a constant 1/16 space, thus why vehicles have such a high natural bass enhancement, when you lean forward you are simply getting a much stronger version of the effect because you are closer to the reflection zone where the bass sound waves are being reflected back at you and are striking against bass waves coming from behind you and are amplifying them selve's.

So you believe that no matter the position or placement of the bass driver(s) in the install you will hear the same thing?
Ive tested firing up, backwards, backwards at an angle and down and they all have a different effect. They also have a different outcome depending on the size and number of drivers and enclosure used.
My car even sounds different between the driver and passenger front seat and thats with the windows up or down.
Im not doubting you have some knowledge in the area by the way you expressed your opinion in your response.
This was in no way meant to be disrespectful Im just sharing what Ive learned from many years of trying different things and having the luxury of being friends with a very established installer.

he is saying that there is no way to place your subs in your car that leaning forward is not going to give a better response, less low end drop off. its just science! (of sound)

Im not trying to argue the science, what Im saying is that the placement can and has changed the way it sounds in the seating position in my car.

infeliciter · 02-09-2010, 06:07 PM

you are arguing a different fact. yes moving it can and will change the way it sounds but no matter where or how you change it, the sound will ALWAYS be louder/more responsive in a smaller space. thus leaning forward will sound "better" regardless of how you move them. therefore do not judge the sound that you will hear sitting in the drivers seat vs leaning forward over the dash.

gravebox · 02-10-2010, 05:30 PM

every aspect of any car that you test in will always give a different result in either side of the car due to the dash formation and the steering wheel and colume and so on. the only time you will have actually increased total sound over the original is by adding more moving mass and suface area, IE, more subwoofers / speakers. in no way shape or form will simply moving the direction of fire from a subwoofer for frequencies below 90hz ever produce increased sound in any part of the vehicle due to the sound waves produced from 90hz and down being 100% omni directional, which means anywhere you point the subwoofer *as long as it's play range is roughly 110hz and below* you will never find an increase of productivity based on the geometry of the vehicle. the only way to increase that productivity is by having more air pressure displacement which can only be done with either a larger subwoofer and or more subwoofers along withh the original.

i take no disrespect in what you are saying, i am only here to help. i've been in the audio engineering feild for roughly 11 years now, unless i say specifically "i'm not sure", i know what i'm saying.

as infeliciter here states, the same subwoofer in a smaller enclosed area say a small car than the original install will always sound "louder" due to lesser sized cabin space. because of this, the inner car air is easier to compress and responds much faster in say a honda to the compression vs. a vehicle like an SUV where there is nearly 4 times the inner cabin enclosed air. this is why larger vehicles require more powerful subwoofers with more surface area and in larger quantities to have the same effect that a smaller, less power single subwoofer would do in a rather small subcompact car. it's all a matter of air compression within the cab of the vehicle. the only thing that effects that is the moving mass, surface area and possible moving displacement of any giving subwoofer(s), the more there is, the louder it gets.

zax1stgxb · 02-11-2010, 05:51 AM

so let me see if i can make some practical application of what you are saying here....

if i have an underseat sub, it doesnt matter if i face it up, or face it down, i will still get the exact same bass......? i have been wondering this for a long time, but others in this very thread have said that down will get better bass sound... so i am a lil bit confused.

1s1ckbox · 02-11-2010, 03:26 PM

its awesome how this became an arguing thread instead of a showoff thread.... wait it is a showoff thread!!
