Theres alot of myth and hype in audio of all descriptions (I now work in the industry its amazing what you find out on the inside
) Most of what people take as FACT is marketing men hype and its amazing how many magazines follow this hype to the letter and have done for decades without any scientific proof or and Engineering (Acoustic, Mecanical or electrical) to back it up.
Cost? I can get most stuff for personal use at cost+10% so around 45% off rrp, so when it comes to the time i want to change something i don't normally loose anything come resale time
before anyone says im wasting money on mods lol. I admit i do loose money on the build mateials though lol.
Im currently waiting for the JBL MS8 processor to come out and one or two other bits and bobs i want to use.
The boot build is in progress and is a simple build like many others already shown here already, I want to keep the boot very practical and useable no painted fibreglass bathtubs here lol. So simply two builds one on either side of the boot one with the sub the other with the processor and amps as i said like others that have been on forums before with stealth covers so nothing stand out at the supermarket car parks etc.
The kickpanels are currently in prototype stage this is were i won't compromise the cars in danger here lol. Theres alot of not commonly known about acoustic theorys been used behind the sences on the frontstage that should improve things.
The key to good imaging is low PLDs (path length differences*) and very solid install with minimum vibration as vibrations cause sound at other frequencies that draw your attension to the mounting locations. Also high quality drive units with low harmonic distortion are needed if i could give one bit of advice to anyone whos building a system its get the best speakers you can don't spend lots of money on exotic amps, exotic wire, fancy source units spend it on things that make a measurable difference speakers and quality mounting.
*PLD In the frequncy range of ~100Hz to ~2Khz if you measure with a tape measure from the voice coil of the speaker on your right to your right ear, Then measure from the left speakers voice coil to your left ear. Then take the right measurment away from the left giving you a +# number if this number is less than 12 inch you stand a chance of getting some sort of image the lower this number the better. In otherwords the further away from the speakers you are the better chance you have of getting the system to image. Above ~2Khz you can compensate for a high PLD by using intensity differences in other words by angling the closest driver away from you more than the otherone. Don't worry to much about the height of drivers as the way our brain/ear system works we can fool it into thinking drive units are higher than they are thanks to us having ears on the side of our heads not on the top and bottom of it.
