ive listened to the SA12, while it is a good sub the sound quality is a bit lower than the focal 27v1 (granted still much better than the "good" main producer's line ups aka alpine, sony, pioneer, jbl, jl etc) however it does have a higher spl output than the focal. However the 1.75 ft box is a bit big for me (sol) and i much prefer my 1.5ft box, soon to be building an extended shoe box soon to fit better and vent via the RQP vents. The SSA's however are VERY nice (the 1ohm 8") and they hit VERY hard, but they require a VERY well designed box to unlock their potential.


IMO while the Focal does sound crisp and clear, it just dont have the output that i look for, or the output for most of your typical street beaters. 6mm xmax and limited to a 4ohm VC configuration just doesnt do it for me.

and honestly, I think the SQ of he SA 12 beats your focal any day. . . not to take anything away from your sub . .. it sounds great and requires little power to do it, but . . . . . . BL^2 is just a much superior technology then the old school method of small gap and bumped back plates that the focals use. And with the uber low FS, the SA12 can get down on some lows while BL^2 keeps the curve nice and flat.

And, the SA12 works well in 1.0 cu^ft sealed if space is the issue, but even with 1.75 cu^ft enclosures, (that is not hard to build either) in the back of a hatchback!!!!!!

i dont think its going to take too much away from his trunk/hatch space.

just sayin

I want somthing moderatly loud (but not too loud) But sounds amazing so i guess sql

I dont need the space really, Im not loading it up

I can build my own but id rather buy


BUY a box don't build one i have seen way to many ppl mess up on the specs the sub needs for it to sound nice. Buy an
(Obcon box ported! 12" type R Buy a 500-600watt rms amp at 2ohms) can always turn the gain(power) down. i would sugest after you buy your system take it to a car audio place and have them tune your amp to what your subs specs are.
12" subs hit lows better and 10" get the highs better.
this is how i see it 10" = head ache 12" = perect 15" = your car is going to fall apart.
I own a 12" Type R and all my friends tell me it sounds better then my friends 2 10" subs. i recommend the Type R.

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...

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".

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.

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.

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

ok u proved my point u been building boxed since u were 12 what if its the first time and they don't want to mess up my friend was positive he wasn't gonna mess up and he did . i'm just trying to be helpful for some dumb blond that may read this damn lol... i don't mean like literally completely fall apart lol.
i know 2 10" subs can be louder. i was suggesting my because i love it and the box i have is made specifically for type r subs. and type r's have a nice sound in my opinion. and i didn't know if he knew anything at all about a system so if not i just said what my setup is and suggested it.

i started when i was 12, but i wasnt always a "pro" at making boxes, and dont consider myself to be

but even at 12, i made my own boxes and honestly, they have always worked just fine

that was the point I was making. . . i can build them at 12 (and im admittedly a dumbass on most stuff in life lol) then people here should have no problem with it

CBR, I like you haha

Derrick just GTFO, building a box is a weekend job at most, all you need to do is goto google, search for "sub box calculaor", it will spit out what you need for volume and port (assuming your sub doesnt come with said info, mine always have, but then again I buy my audio new).

Then just do a little HS geometry, cut, glue, screw, and carpet your box.
and PS your alpine type R's.... sound like doo doo butter. I know, i had them in my hatch, and sold them a month after I installed them.

you must of had the type r powered wrong or something it sounds hella sick. and i'm not saying i don't know how to build a box i'm just saying there a some people who are dumb as frack and would rather buy a box. or just don't have the time to build one.

I honestly for one can say, Type R's are good bang for the buck subs and can get very loud in the right application. I have seen people hit over 150 with a singe 12"

yeah but their image depth sucks, they hit a very narrow range, no good for SQ, but great for SPL (and im sorry, i like to listen to my music, not hear 2 notes)

yeah have you ever heard them in an enclosure spec-ed to each sub? I call BS on the type-R's specs, they have 2/3rds if not 1/2 their advertised range. Not to mention they sound like they have a layer of crap sitting on the cone.

I was actually looking at going with the type-r's before i found my focals, heard them side by side, there is a reason i spent the ammount I did on my sub.

Id say thats a pretty flat curve.

Im not accusing the Type R of sounding better then a Focal, but there is no denying that for the price, they are one of the best subs you can get for your money.
,
They have a great motor design and the CRC pole is outstanding on that sub.

Because of the way these subs are designed, they really shine in terms of output when set in SQL/SPL applications, but they (at least the new ones) hold their own in SQ setups as well with moderate power pushed to them.

To try to say the sub is a POS just dont do it any justice. This sub has the ability to excel in alot of areas where youre sub lacks. Take out the biased towards SQ and your sub is actually pretty worthless to the average consumer who is just looking for a daily street beater.

There is no special technology in ur subs that make them sound good to be honest. They just have well balanced soft parts, and Focal usually has really good control of the cone. But, thats easy to accomplish when you have small amounts of linear excursion. The output still suffers.

Where as. . . you can grab up for example. . a Stereo Integrity Magnum, drive the piss out of it and it still sounds crisp even with gobs of power put to it.

to cut this short. Your subs are designed and built strictly towards balance and the ability to be musical at the expense of output. You are a very small minority in the car audio world.

You say you like to "hear" your music, I say "I like to have fun" :)
