Not everyone is pro at making a box. A lot of people say oh i can save 50-100$ if i just make it. Then i watch them build a box that is completely done wrong and not ported correctly and then the subs sound like crap but are powered perfect...
you dont have to be a 'pro' to make a box. Im not a pro and i have been building hem since i was 12 years old lol. You get measurements, you cut them out, and then you screw and glue the wood together. Its nothing you have to be afraid of doing.
we will look at it this way.
Advantages of building a box yourself -
You can custom tune them
Custom fit them
Build the box to TS spec
Rip it out, trash it and start over if you dont like the results
Cons of buying prefab -
They cost an arm and a leg where as building it yourself only costs you a sheet of wood, glue, and screws.
They are not to TS spec in most cases, your often just trying to adapt a box to fit a sub
Very few cases where prefab boxes are the way to go, and very few companies are even worth a crap. Kaotic for example makes very nice boxes, but you submit the measurements to them, its all hand built, and is still expensive
My personal opinion is that a 12" is perfect because it hits the lows and highs amazing 10" is alright but i like more of the low bass so i prefer 12"+ subs it makes the music a little more enjoyable a 10" just doesn't cut it for the lows for me. with my 12" type r its like a constant back massage because of how nicely it hits the lows.
and when i give my opinion you don't have to comment on it. everyone likes a different sound and idk 10" subs just give me a headache and iv seen a friends car fall apart from a 15".
first off . . there are 10 inch subs out there that can hit the 20hz ranges.
There are no subs that hit "highs" thats what tweeters do, perhaps you mean to say higher end of the low range spectrum? I dunno. ..
the way a sub performs is all relative to the enclosure. has less to do with what size sub you are using. You can tune a 10" type R to hit the same low end freq. then even the 15" Type R. The only reason a 12 or 15 is louder is because it has more surface area thus moving more air. But consider this. You can install 1 x 12" and I can Install 2 x 10" and be louder then you. . .
And as far as speakers tearing peoples cars up..... its pretty much a shytbox you own if a speaker is busting it apart. Ive had a CRX with 8k watts and 4 15's to my last system which consisted of 4 18"s in my suburban and not once did my cars fall apart lol
why do you say ignore my entire statement going to an audio shop to get your amp tuned properly is a good idea for people who probably don't know crap about subs just want it for the bass. Don't assume everyone you talk to knows how to build a box or tune an amp.
If you are competing, yea, go get your amp tuned and dialed in.
But on here, i seriously doubt that anybody is competing. I posted up instructions a long while back how to tune your amp using a simple DMM. Its another thing that is just not hard to do, and if someone is so retarded they cant get on the internet and look up "help tuning amp" then they probably shouldn't own a stereo in the first place. . . . or be driving for that matter
