FR-S / BRZ Front Stage
 

What are you all installing in the dash and doors for your front stage? I was looking at these in the dash http://www.crutchfield.com/p_136C235...50x.html?tp=96 . I would like to do components up there if we can get a 4" speaker to fit. Then I can run a 6.5 or so midbass in the door.

Trying to decide this myself, i may end up with a wideband 3" in the dash and 6.5" midbass in the doors, no tweeters ;)

Just a note, these are available from Amazon for for $48.

I'm running Focal KRX2 mids in the doors and Dynaudio MD130 Tweeters in the dash. I would like to hear a quality 3 1/2"/4" in the dash and see what I think. As of right now I'm not convinced I like going too low in the dash. I'm crossed over at 4k and anything lower starts to get harsh. Not to mention, to properly run a mid up in the dash, you will need to make some sort of baffle, which will not be easy.
With my 6 1/2 in the door and tweet in the dash, my soundstage is high and centered, I'm not convinced the mid in the dash is worth the trouble unless you maybe compete. Just 2 cents.

Thanks for sharing. -max- , you dont think i could get away with xtc baffle in the dash? I've seen a lot of folks running 3 1/2" and I reckon that is the largest you can fit.

Joeboxer, that idea sounds pretty neat.

I've given it a lot of thought and I'll probably end up with some decent 3.5" coaxials in the dash and a 6.5" woofer in the door. I know that sounds low rent but it should be better than what is there if I improve on the existing install with dampening and such.

In order for the driver to work right, you need to separate the airspace if front of it from in back of it. You really need to completely seal the hole in the dash. I have not seen pics of anyone do it right on here yet. Not saying it has not been done, just that I have not seen it yet.

It doesnt seem like it would be too hard to just dremel off the back of the tweeter pod and build a spacer to fill that whole area.

Go for it man. I would love to hear a good 3 1/2" or 4" in the dash. See what it sounds like.

I'm going to be running the JBL MSBassPro SQ in the trunk and h audio trinity in the dash and h audio ebony in the doors, I will run them off the factory amp for now until I can afford the jbl ms-a1004 to run them active with more power.

Just found in the other thread the factory 6.5's are 2ohm so i will try to find some 2ohm drivers for the doors. In the dash i'm looking at the H Audio Trinity/Fountek FR89EX 4ohm or possibly the Dayton RS-100 which are a little cheaper and should fit pretty well.

Wow, 2 ohm drivers huh. I wonder if the dash speakers are 2 ohm?

If I got with 3-1/2" coaxials in the dash which ones should I get? I've thought about Infinity Kappas, Boston Acoustic, Focal, and JL Audio. Are any of these heads and shoulders better than any others?

I have Hybrid Audio L3SE's in the dash. 3.7" Wideband driver.
I am going to put in my L6V1's in the doors this weekend.

currently running off the factory deck, plan on installing my amps/carpc setup in a few weeks.

but with the L3SE's and no tweet the sound quality and imaging is fantastic! Can't wait for amplifiers!

The dash speakers are 4ohm, the only ones that are 2ohm are the ones in the doors which run off the amp in the back of the car.

How do you think that L6 is going to work off the factory amp which is only putting out 33w @2ohm? I'm tempted to put my Trinity's in the dash and leave the door speakers alone but i will wait on your review before i go any further.

Got Morel Elates's in the front bi-amped and it sounds wonderful. Using a DSP and it pushes the stage out very nicely. Without the DSP it still sounds very "good" to normal people. :) The midbass is VERY tight now that's I've matted both doors.

Yes, both the tweeter and mid in the dash are 4ohms but connected in parallel therefore the HU sees a 2ohm load for the pair.

It'll work for normal levels, but i'm not about to push it up higher in volume without better amplification.

When i talked to scott @ Hybrid Audio, he said to bandpass the L6 50hz-250, and Highpass the L3SE from 250hz - up.

should sound incerdible when all the processing is setup and properly EQ/Time ' ed..

Oh really thats good to know so how are the frequencies broken up for the mid and tweet? is there a cap on the mid or something? I think i'm just going to leave the front stage alone until i can do it right after seeing this info.

Zorro do you think i should try the Trinity's or wait until i can get an amp and do it right?

Wait for an amp, the stock one is a joke.

Yup, there are caps on the mids and tweeters.

Yeah i guess i am going to just install my MSBassPro SQ and go from there, i may replace the stock 6.5's with some 2ohm JBL Power mids if i can find somebody to sell me some seperately and then just sound deaden the hell out of the car.

Did you put the cap back on the L3SE or are you running it full range?

Full Range. (I do not push them) I did not move the cap over. I took the connector off the stock speaker, and connected the 2 wires to the L3SE. the tweeter was disconnected by clipping the leads, that way i could solder them back if i went back to stock.

i'd wait until you have a decent amplifier. I was just wanting to play with my new toys.

It's kind of like masturbation when you are still a virgin, fun in it's own right, but not nearly as good as the real deal :) HAHAH

Bahaha i appreciate all the info i'm still not sure what i want to do up front the sub stage is handled though.

I still have to do the rear quarters and wheel wells, but the car is twice as quite already as it was. Haven't even done the ceiling or floor yet either actually. The doors and trunk are very noisy.

I've added a little on the trunk lid and in spare tire well but not enough to tell a difference. I think i'm going to do the doors, the rear interior panels and do a better job in the trunk.

I've got my amp install kit ordered to hook up the JBL powered sub.

The distributor for H Audio/Audible Physics is going to put a cap on the 3" speakers i'm buying so they will be ready to drop in and i won't have to add an amp or separate crossover for now. Guess i am replacing the speakers now too and putting the Ebony 6.5's in the doors for the midbass.

The rear deck really sucks also when you add a little bass.

now that i got a FR-S under my belt, i can chime in.

stock locations 2 way, 6.5" mid in door, 1" tweeter in stock 3" location, full DSP, active.

it does quite well, i playd around on the rta for about an hour and then tuned by ear for an hour. center is very solid with GREAT depth, width is pillar to pillar but not beyond, height is a few inches above dash level whcih for me is perfect.

tonality wise, obviously i need more time, but with the stock locations, i can see some small reflection issues, on the rta, most notably the spike in the upper freqs, 16k to 20k, though its doubtful you can really hear it.

there are also some valleys and dips that i was able to correct pretty quickly with the eq...

here is a shot of the curve i got while i was wokring, this is before i finalized things...then i turned off my computer without taking another screen shot.

the bump at 80hz was easily fixed, i simply had the sub at a 24 db vs 12db.

the things to note that i think were a result of the reflection and location of the tweeter:

the 16-20k bump and there are some small spikes between 5k and 16k, but most were quickly toned down. (the final curve looked a lot smoother uptop)

of course the speakers also have something to do with it.

so basically, i would say, a dash mat of some type would definetly help in this car, though off hte bad right now, it still very good.

i was also surprised that despite having a closed off trunk with no rear deck speaker, the bass came through quite well :)

so i would say...stock locations works well for sq

if you want to make it better, get a nice plus dash mat

if you want to really make it be the best you can get, i would recommend molding the stock location to house a 3" driver tilted back at you a bit. and if you do a 3 way, mold the tweeter into the A pillars.

thats how i would do it if i were to approach a FRS/BRZ with highest possible SQ being the goal :)

Thanks Bing! I have ptetty much the same set up you are describing I've noticed some of the same things you mentioned. A bump at 80hz, some reflection issues. Tuning by ear so far, but trying to get some RTA time. I would have to say my stage is well above the dash and plenty deep also.
Will there be a write up? Waiting impatiently!

there will be a write from me on diyma, a two parter since i am doing two FR-S back to back, with slightly different budget levels and focus, both will be active DSP, the first is higher end stuff with a bit more power, the second mid line stuff with moderate power,

will have both up hopefully by the end of the week...

these cars are a true joy to work on...like all scions :)

That's pretty much what I was thinking of doing, except mold in a 4" instead of a 3" mid.

Which way do you think would be best to aim the tweeters, if mounted in the A-pillars?

I actually got another set of A-pillars already and will probably mold in the tweeters when I return from overseas.

with how steeply raked the windshied is, i would say you can go relatively off axis on the A pillars with a dash pad and you will be okay, most of the reflections may not reach you. but for the best results, yo can always experiment and do it on your own. there is no perfect way imo, it all comes down to speaker, car, personal preference

Nice to have you here Bing, Mark from H Audio/Audible Physics has some Trinity hybrids he is setting up for me with a cap on them to run 500hz and up, H Audio Ebony in door locations both off the stock amp for now until i can afford to get the JBL MS-A1004 to power them. Substage is the JBL MSBassPro SQ 10" powered sub. I will post some pics once i get them here.

Very true. My tweeters are swivel mounted anyway, so I can adjust their positioning some.

i would be intersted in seeing how the full rangers perform in the dash, my guess would be that it would be pretty nice. :)

maybe i will get a chance to do that in a FR-S soon

b

I paid for mine last night hopefully Mark gets them out soon and i can post a review. I've got the JBL MSBassPro SQ 10" sub that i can remove easily if i need to take it to the track also.

i know the Ram i did with upward firing stock dash locations worked VERY well with the XR3...

Can you post pics I am looking at going the Legatia Series front stage in my 86

Looks like I will be going the wideband route also. Stuffing some 8s in my doors and working on some xr3s for the dash.
