Close - it's more like 15k and drops as you get older.

But your reasoning doesn't support your statement. Because you're deaf does not make his car sound any less good. Most non-deaf people would agree that it sounds good, so it does. And for that, a good sounding car is a good sounding car.

... wow you are working too hard at making a good statement bad

a trumpet will always sound like a trumpet and it will sound as a trumpet is capable of sounding irregardless of age related or mild hearing differences

a snare drum will always sound like a snare drum and it will sound as a snare drum is capable of sounding irregardless of age related or mild hearing differences

a SQ system that sounds like music will sound as good as music is capable of sounding irregardless of age related or mild hearing differences, the problem comes when someone doesn't know what a trumpet or snare REALLY sounds like

BTW the MTX car at CES sounded terrific good tone, staging, placement, height and I didn't listen over 80 dB ... sure MTX isn't the first name that comes to mind when you say SQ product but... you can get there from here

Not his fault. It takes dedication and desire to compete in that class and not a lot of people have both.



Why? Why do people immediately point and say "but but, HE'S got a WALL!! *snifff*" Hasn't it been shown that it doesn't matter if it has a wall or a conventional box? His car has a wall, deal.



Why, cuz it doesn't look and sound like ?



And there's lots of SQ cars that go loud but don't compete SPL.
And there's lots of loud cars that don't even compete.
And there's lots of good sounding cars that don't even compete.

The point is that there are very few that compete, and do well, in both SPL and SQ. 15 years ago a real comp car had to do both. Those of us who remember those days think that's the right way to build a car. Step up if you think you can.

Just pissing in the pot..
I dont see the point of competing both when you would have to have a compromise between the two and therefor wouldnt do as well in either category.

My vehicle isnt a burp monster...it plays music, and is daily driven. I could also compete in SQ with it but I personally dont see the point of building to a set rule book and what the judge is looking for rather than my own personal taste since Im the one who would be listening to it everyday. I also demo my truck at shows...something very few people do anymore.

I never said MTX wasnt reliable product...but I dont consider it high level gear for SQ or SPL. The jackhammer is the biggest joke ever produced in car audio.

It is difficult to compete and do well in both SQ and SPL and win at both. But my point is that the only reason he's winning is because its by default in SPL classes for the most part. In SQ he does very well however, thats why Im saying his vehicle is much more SQ oriented than SPL.

My point of it being more impressive without a wall is that then it would be much more challenging to do 151s and beat the competition on the SPL side of things because there would actually be people to compete against. Rather than just building a wall with a good amount of cone area.

Its clearly more SQ oriented than SPL because the world class guys are almost 20 db above in that class. Even street A competitors with a single 12" sub are 7 db above. The SPL portion of the car is not very impressive IMO.

The old school way of doing things is just that...old school. Its outdated and the way rules are currently it will get beaten in both types of competition. The key to winning and having an impressive score in SQ or SPL is having your vehicle dedicated for one or the other.

I would have to agree with Paul on some points if you have been around car audio 15+ years then you can appreciate systems that are "old school" with a certain nostalgia.

Its too easy to do just spl or just SQ if going by a set of rules. The real appreciation comes from building a system that is quite loud and does sound as good as it was on the recording studio monitors where the music was recorded in.

So I guess that would be my own definition of sq, sounding similar to the monitors in the recording studio. Take that sound now to a vehicle, eq it to the new enviroment and warm it up with some more bass and thats what I like lol.

Now how about them pictures.....

what makes me laugh about this thread is that 90% of respondants really dont have any idea about SQ or SPL. Gotta love CCA. This thread needs an educational post from loudlemans.

there are a few really loud systems around here that sound absolutly fantastic
but they have no interest in competing

I even know of one that can hold 143.6 to 147hz range from 10hz up to the X over
point of 70hz...that's like a 3db variance from 10hz to about 75hz (with four 10" ported)
and it is backed by more than equal on the top end...does well on the mic and sounds
outstanding with almost anything

just because they are not at the comps doesn't mean they don't exist

I personally think only about 1-in-10 Fully built SQ cars actually ever compete. 2 of my cars fit into that category and I do installs for at least 5-6 people a year fully oriented towards sound quality. The installs my not necessarily be to guidebook rules but as far as the listening experience and quality of install goes they sure could score extremely high in the subjective judging parts as well as on the RTA's... I'm really an SQ guy, but every now and then I too enjoy scrambling my brains and getting a free back massage bumping some oldschool beats

I agree trevor, and from what I know of ppl the reason they aren't competing is because they fear failure LOL... It took me spectating 3 events b4 I got ***** to make an *** of myself and hit the mic in StB @ 143.8db LOL I guess not bad for low tuning daily driver.

I also agree with you yuli, I dont have the slightest clue about sq and I am still learning about spl'z

db don you can check out my ride on members page. also check out my post called whew finally done, also all pics of my iasca usaci championship sq 03 honda civic and my iasca db drag sq and spl winning yellow car are on photoshop and my yellow mtx preped car is on mtxs web page as well. now the only other competitor that i know that can do what my car does is my main man in pg. BROTHER JOE!! we both hit over 150 db in DAILY DRIVERS, and due great................not well.......... but great in sq... all i have to say is lets get some skill in the design of the spl car or sq cars... just because you want to go loud dosent mean you have to do shoddy work, or because sq you dont have to design a loud and responsive box, or soundproof your car!!
