Kyblack76 Posted June 7, 2013 Report Share Posted June 7, 2013 Wanted to toss out the SLOPE.. Big time affect there... SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
BoomZoom808 Posted June 7, 2013 Report Share Posted June 7, 2013 I like a 24 db slope for subs. The steep fall off will help with the peak. I was having the same issue with my system playing real instruments. Kick drums would overhang too much. I had to go full tilt and tune a lot to get it to sound right both with gain + eq. Now if I do play decaf I just back off 45hz a bit nice thing about the PEQ. 2010 Mazda 3s 2.5L Pioneer DEH-X9600BHS Knu OFC 1/0 SS Platinum AGM / XS Power XP750 Alpine PDX F-4 / Morel Maximo 5 + Coax 5 IA 10.1 / SSA XCON 12 Link to comment Share on other sites More sharing options...

TylerParrish Posted June 7, 2013 Report Share Posted June 7, 2013 Would really like more info on tuning. Also, good luck Stang on getting your system sounding good, I know this is definitely a topic I'd like to know more about.

scoobywrx05 Posted June 7, 2013 Report Share Posted June 7, 2013 Like it mentioned in the video I used a pink noise sweep from 20-20k but that was after I played with the eq for a couple weeks. Remember that the app isn't very accurate without a proper mic and rta is only good for finding peaks and valleys and adjusting them properly. After it is relatively flat you'll want to adjust your eq again to your liking because a car that is flat on the rta sounds like ass. If you have any nulls in freq. response or "Valleys" that need more than 6db boost I would start looking at the components for issues. Setting gains properly makes a big difference as well. It is all well and good to use a dd-1 but the peak output of the amplifier isn't always what you will need to maintain the balance. There is also the possibility of it not distorting but still raising the noise floor. If you use PA gear it is much more noticeable due to the speakers sensitivity. There are several ways you can tune but I would go through this checklist. 1. Set the crossovers on the amp or in your case the HU. 2. Level match the gains so the output is even across the freq. spectrum. 3. Listen to just the tweeters and listen for how they imaging and stage. If it images low or to far to either side adjust the polarity and see if this improves staging and depth. 4. Repeat the process with your midranges and midbass if you run 3 way+sub. Once you have the staging and imaging down you can worry about tonality. You will tackle that with eq...and T/A should be the last thing you should do. Speaker placement should give you a good step in the right direction. 5. There are a couple ways you can do the next step but what I did was use the app on my tablet and ran the full freq. sweep and wrote on a piece of paper where the peaks and valleys were. I had two large peaks in the midbass region and 1-3.5k. Every vehicle will be different due to cabin size and shape and speakers used.but most cars have a midbass hump that will need some moderate eq'ing. It definitely made my system more articulate and cleaner. 6. Make small adjustments and run the sweeps again until it is relatively flat. 7. Once this is done put in a piece of music that you are very familiar that is well recorded and make small adjustments. I found that it is better to listen to this song or songs you use to do eq'ing on a pair of nice headphones or a home reference system before you start. Most of it will be experimentation until you get familiar with what instrument or voice corresponds with a certain freq. Since you have 15 bands per side I would mirror them until you get the sound you like. 8. The adjustments need to be 1-2 db at a time. I've tried larger cuts but I found that it "shocked" my ears and threw the whole process off. 9. Make sure you listen to the whole song and not just the dynamic passages that are giving you trouble. Write down any impressions that you have and record the adjustments so you can look back on them if you boost or cut something and don't like the sound afterwards. 10. After this you can do any minor time alignment adjustments that you want but it shouldn't be much. 11. There will be an "oh shit" or revelation moment after you do these steps and it will be like listening to all your music for the first time again but that will pass. lol There may be music that you liked before that you may not like now and vice versa. Sometimes hearing music the way an artist intended is a double-edged sword. You will continue to make small adjustments and there will be times that you will get back in your car and say "What the hell was I thinking"; in terms of adjusting something but it is all part of the process. It is important to take several breaks during the process regardless of listening fatigue and never rely on one song to do all your tuning. I used tracks like "Hotel California" "the tourist" by Sarah Jarosz "A call to arms" Glory soundtrack "nullo in pax sincera" from the Shine soundtrack. It's in my video ^^ at 9:05 "Blueberry Pancakes" by Fink Pretty spot on. Nothing really to add I can think of off the top of my head. Some other music I use is Seal(older CD) , few songs from Dave Matthews band that are done well and Korn MTV live isn't to bad either. Definitely no compressed music if you want the best out of it. Once you get it set up you will be surprised at what you have been missing. If ya have any questions Ken please ask away. I personally don't have the 80prs (have had the chance to set one up tho in one install, good deck) I actually am old school and use a Rockford epx2 with the 28 band eq in my ride.

michigancapri92 Posted June 7, 2013 Report Share Posted June 7, 2013 definitely only use CDs ... back to the topic of subwoofers ... whats great about the 80prs is the time alignment ... try doing everything at a 12db slope, with the 12db slope yes the sub will play higher into the range BUT .... with time alignment you can get all that sound un front of you on the dash ... you would be surprised at how well time align will get those subs playing in front of you ... in which case if the subs did play higher into to frequency range it will be ok because the sound will still be perceived to be in front of you. in essence also letting your front speakers not work so hard.

White Lightning Posted June 7, 2013 Report Share Posted June 7, 2013 For the most part of testing and tuning ... You will basically flatline your EQ and mainly concentrate on your time alignment, phase, and crossover settings ... Then make you a mixed drink, get relaxed (RELAXED ... not drunk LOL) and get ready to listen to your music ... Then adjust your EQ accordingly to how it responds to YOUR ears. Electronic devices help, but can not compare to your ears ... Kenwood / HELIX / Linear Power (For The Love Of Music) / Brutal Sounds / OverKill Electric Co Questions About Sound Quality ??
