I suppose since most of the folks I know interested in car audio are much younger than myself, I don't too often hear many systems tuned for SQ. Not that I wasn't the same way when I was younger, all I really cared about was how loud the system would play and the sub bass always seemed to have the biggest impact on SPL. It seems today that most of what I hear at shops and from the few folks in our area that have any sort of major system is SPL with the bump in the 40-60hz range. So... what's the best sub setup you've heard lately as it relates to accuracy and sound quality? Single or dual; 10's, 12's, or 15's; sealed or ported; etc.??
One of the most accurate systems i have done used a 15 inch jonah lamu fusion in a 3 cubic foot vented enclosure. It was fired up through the rear deck, both woofer and port, the rear deck was modded to allow unrestricted air flow. the low end was amazingly accurate on virtually all sources of music. the RTA proved this. It was a system that i wanted in my car! Another sytem I did was an Infinite baffle design, that was rather tedious, but the end result using 4 10 inch orion IB's on a 225 HCCA was also amazing. tight, fast and very smooth in its response. And believe it or not, years ago, I put 2 six inch punch 6" ina small vented box in the rear well of a 86 camero, those two little woofers running off an old punch 150 would hit fast and make the kick drums sound like they were in your chest. Lots of ways to get good accurate subbass in your car, just need to experiment some
That question really got me thinking. We did a bandpass box for my wifes Taurus that had 2 PPI C2 10 inch subs. We gave PPI a call and they faxxed us something like 6 or 7 pages of differant boxes that would work. It took us 3 full days to build it. The port was aimed through the rear armrest. Pushed it with a Fosgate power 550s. This thing sounded awesome with anything you would play, Rock, Rap, Classical, Jazz or whatever. It was quite loud as well. But wife got flat tire, called auto club. They could not get the spare out cause the box was so big. Wife not happy== no more box. Oh well lesson learned.
I'm still really impressed with the older JBL GTI series. They had basically the same basket/magnet as JBL's pro drivers. The problem is every vehicle is different, and different speakers/boxes sound better in some vehicles, than in others. That being said....watcha gonna put it in???
This was posted more out of interest than intention. I'm fairly happy with my setup I have now as far as accuracy. I'm so limited in space (gotta have that room for getting the spare tire out) and I'm so picky about keeping with as much of a factory look as I can, I'm not sure there is much else I could actually do. I may try out some other 10" drivers some day... if they'll work in the box I have installed right now. My box size is pretty much at maximum right now with 1.1 ft^3 per driver.
It would have to be a 93 Honda I built a bunch of years ago. It had 4 10-inch Polk Audio Momo's in it. The box was 4.25 cu ft and sealed. But for SQ competition, I always turned my sub in my truck off. My trucks door speakers and center handled everything very well. The RTA always showed a flat response with the sub off.
I think one of the most detrimental things that folks do is turn the bass up too loud thinking that it has to be loud to be musical., it dont!
I concur... I have tinnitis anyway and if you could hear what I hear when the bass hits... you'd say "where's that crackle coming from?" ... lol. I crank her up all along, but it's usually for just one song here and there. When I pop in a Pink Floyd song I just can't help it. But generally I'm at a lower volume and it's important for me not to have to crank up the volume just to hear bass. I definitely don't want the bass to overpower the mids and highs.
Especially in competition. I competed from around 98 to 02 and trophied 24 times (I dont compete any more, school work takes Precedence). My main advantage was the fact that I knew how it should sound. Most people have to mush bass, not enough mid bass and the treble is maxed out. If I ever build another SQ system (I'm dreaming) it would have 2 6 x 9 in Custom made Q forms and an 8-inch center. It would have three amps. One for each speaker. ( $985 per class and four classes a year prevents me from doing this and books for this semester was 360 dollars) My son starts college this year, donations will be accepted send to ........LOL
I could not agree more. I have all my sub settings aound the 1/2 point and then on my hu I have it at -2 for the sub. Once you turn up the sub too much you take away from the highs and mids. We must all keep in mind that you want to replicate actual live music which is a blend of everything. Not just bass. Under200
Dude, pink floyd has great overall sound. Great tight bass. LOVE to crank that **** when i'm cruising around town.
