Okay I built my first enclosure with the help of an experienced car audio installer who has been in the business for 25 years.
2012 Scion TC.
System: Pioneer Head Unit, Full dynamat sound deadening, 120 sq ft, Hertz Energy 3 way component fronts, Hertz Energy Coax rears, JL 300/4 amp, JL 500/1 Amp, 10W6v2 Sub, PAC LC1 controler for sub output, knukonceptz wire throughout.
Previous enclosure was a pre-fab tuned to 42 hz...
New enclosure is 38 wide x 13 high x 10 deep, 1.8 CF, Tuned to 31hz, L Port Length 22 total, 1.5 wide at back of box, angled from 1.5" to 2" at opening on the front of the enclosure.
Front speaker crossovers in door, neutral on tweeters, mid set to -2db.
4 channel amp crossover settings 55hz fronts, 60hz rears per hertz specs on speakers
Sub Amp settings, crossover 63hz subsonic 28, gain just bit over half, boost off.
The sub sounds really good but when first connecting it up the bass boost caused too much boom and almost seemed as if the sub was losing control, turned it off.
My initial crossover setting with the old prefab enclosure was 55, but when listening to the new enclosure which was lower tuned it felt like there was almost a gap between the mid and sub, so I bumped up the sub crossover to 63hz which seemed to let it blend much better.
Lastly when the sub level is too high certain frequencies in music seem to boom and lose control and almost have a delay, backing the sub level down seems to cure this, is this normal?
Is it okay, normal to move the subs crossover up a bit higher when the enclosure is tuned lower? Would this also be a main reason people add mid bass drivers to the front? Is it okay to have the sub crossed at 63?
Right now I'm at the listening and tuning phase which consists of driving to work and back and changing the settings slightly each day then listening again until I have things set to where works perfectly for all types of music I listen to and the only adjustment needed at that point is front the center position on the PAC LC1 sub level control to reduce or increase depending on music source.
Have enough material for a 2nd box was considering tuning it to 34 or 35 to see if this would provide better sq, but still thinking about that one and researching more. JL Spec ported box is at 37 with much smaller CF.
Any input, thoughts, advice are definitely appreciated.
