Hmmm.... what I can tell you so far is:

50V
Bipolar
Radial
105C

But, trying to find the actual OEM value is proving difficult for me. But, I'll keep looking.

Its a bass blocker. Probably around 22uf, 33uf, or 47uf ? The value determines the crossover frequency. A 2,000 Hz crossover @ 2 Ohms is around 40uf. 22uf would be just under 4K, 33uf somewhere around 3K, and 47uf around 1.6K. Although, I think the tweeter is 4 Ohm. Which would probably be 22uf for just under 2K.

BTW, uf=micro farad, pf=pico farad.

 

Thanks. Capacitance also depends on the impedance of the speaker. I'd like to keep the stock cross over point but use a better cap. Electrolytics degrade with time and heat, two things in great supply with my 00 black Celica. Swapping from new wet to audio grade poly something in a pair of Dayton speakers totally pulled the harshness out of the tweeters. That's my gripe with the Celica tweeters is they're a little harsh at times. It's cheap to try and I need to pull the door panels to fix door locks and a rattle.

 

Just be careful. They are NOT standard polarized electrolytics. They are bipolar (a.k.a. non-polarized) ones.

 

Yep. As are the audio grade from partsexpress.com

 

:thumbup:

 

I'll put a link up when I get home.

That's what I used on the bookshelf speakers, I was thinking of the same product but the correct value for the stock tweeters.

 

Should be fine.
Still haven't had any luck finding you an OEM value.

 

Yea. I'm going to see if someone parting out can check theirs for me.

 

Did that GTS have premium sound? If so can you do me a favor? I'll paypal you some $ for your troubles if you want.

What is the favor?

I need to know the capacitance value of the blocking capacitor on the Premium sound system tweeter.

I will see if I have a tweeter off of the car, I should have one. I can take a look. I don't imagine the tweeters are much different if at all than the regular system.

They're probably the same but the premium has that mid hung over the woofer so they may have crossed the premium tweeter different. I want to get my parts here so I can just work once instead of tearing the doors off multiple times for each thing one by one.

Here is what it says on the capicitor:

ELNA
CE-BP
50v
3.9mF(k)

Speck to the rescue!

So that would mean it's a 4 ohm tweeter at about 10,000hz cross over. If it were a 2 ohm tweeter that would be a 20,000hz cross over and....that's not logical.

PE has this, which is pretty close and drops the cross over about 100hz. I don't know if that's going to be harmful or not, I'll ask a car audio forum for help on that. I'll order them up once I get an answer to that question.

http://www.parts-express.com/dayton-audio-pmpc-40-40uf-250v-precision-audio-capacitor--027-226

 

9937.5 Hz Close enuf for gov't work.

Seems a bit high to me. Tweeters usually reproduce 2K-20K. Although, mids usually go up to 4k-5K.

Seems like there would be a hole in the overall range w/a 10K x-over.


Err..... and you don't have a mid if its the JBL. The JBL crossover will be different than the '00-'02.

 

Yea, but they probably have the mid with a cross over on it too....now that I think about it. (or is the mid filtered in the amp/head unit?) And the front woofers are on their own woofer channel I seem to recall, correct? The rears are full range though, right?


I assume that the tweet is 10K and up, the mid is probably 12K to 300hz? and the woofer is 300 to distortion. I'd love to know the actual break down on that.

 

Nope, no sub on the JBL.
The JBL fronts & rears are 2ways - woofer/tweeter combo. 8 spkrs - 4 Frt, 4 Rr
The '00-'02 fronts are Mid/tweet w/separate channel sub. Rears are single full range. 8 spkrs - 6 Frt, 2 Rr

*Although, there was also a 6 spkr std in the '05 GT-S. Which probably meant full ranges in the rear. But, those also were probably not JBL. I believe the JBL was strictly optional & w/8 spkrs.

 

Yea, I have the 00 8 JBL speaker system with the factory external amp. 6 up front and 2 in the rear. My understanding was as follows.

tweets and mids are on their own channel, front woofers on their own channel, rear 6.5's are full range.
In the front there's a tweeter, a mid suspended over the woofer, and the woofer, in the rear there's just a 6.5 woofer (per side of the car). I know that the other Toyota JBL systems process the sound into different channels for the speaker type, the Highlander system for example has mids and tweets on their own channel seperate from the woofers in the doors, I thought the Celica JBL did this as well.

'00-'02 Premium sound:

This 8 speaker system has 3 component speakers in each of the front doors. The tweeters & mid speakers are tied together with a high pass filter to the tweeters. The bass/sub speakers are driven by a separate output from the OEM amp. The rear speakers are single full range speakers. Making a total of 8 spkrs.

 

Yea, I have the 00 8 JBL speaker system with the factory external amp. 6 up front and 2 in the rear.

Doesn't exist. The '00-'02 were all non-JBL. You have the '00 non-JBL(Fujitsu) 8 spkr w/6 Frt, 2 Rr. Frt sub on separate channel.

JBL was only '03-'05 and the amp was only 4ch, not the non-JBL 6ch in the '00-'02.

 

I could have sworn something said JBL somewhere, but I guess I'm mistaken! LOL


SO anyway, do you know the cross over for the mids and woofers? We know the tweeter now for the 00-02 premium,

 

That's done by the amp for the front. The woofer/sub has a separate output channel from the amp.

 

I know it's done in the amp, I'm curious the points at which it rolls off at.

 

No idea.

 

Maybe when I have it apart I'll use my iPod app to figure it out. I can play each speaker one at a time and graph the spread of sound.

 

Back from the dead!

I have a pair of tweeters coming to me, one from a 6 speaker system and one from an 8 speaker system. They do use different tweeters, not just different cross over values.

86160P SPEAKER ASSY, FRONT NO.2
86160-2B470 6 SPEAKER, RH 1 $122.33
86160-2B480 6 SPEAKER, LH 1 $122.33
86160-2B520 8 SPEAKER, RH 1 $116.95
86160-2B530 8 SPEAKER, LH 1 $116.95

Physically the tweeters are different. The 530 must be a much higher frequency part than the 470 since the 6 speaker system lacks the mid driver over the front woofer, so the tweeter on the 6 speaker must be crossed lower and be a different part to make up for that lacking mid.

I have one 2B470 and one 2B530 on the way. Other interesting thing I found when looking up part numbers...

There's a 4 speaker option for the Celica somewhere somehow. I never knew that, must lack tweeters?

So why does anyone care? No one cars. Why do I care? Because I'm trying to figure out if I can just cut and paste these AMT drivers into the car. The power handling matches, the ohms match, and the size looks pretty close. I'll measure the tweeters when I get them and see what kind of cutting I need to do on the door panels if any.

Supposedly AMT tweeters sound amazing, which would be great because the tweeters in the 8 speaker system are it's weakest link. They're very shrill when the volume gets high and pretty harsh even at lower volumes.

yes

 

Sorry, I'm just kind of thinking out loud as I post. :rofl:

A friend of mine has those AMT pods in his BRZ (totally aftermarket sound system though) running at well over suggested wattage and he likes them. He says they're super clear without being harsh but very highly detailed that you can hear compression artifacts very clearly from lower quality sources.

 

The AMT should be plug & play for ya w/the cap value from the 530.

BTW, post the cap values on each.





EDIT: & yes, the 4spkr system uses the same spkr, that's in the rear, in the front.

 

I'm going to try to match the stock cap with an audio grade film cap, I'll spring for the pricier matched ones that are within 1% of each other.

So what cars got the 4 speaker system? :wtf2:

 

I'll do one better, I'll measure all the dimensions with my caliper and post plenty of details and photos and as much information as I can glean from them.

Also, since I now have most of my things I'll be pulling a door panel soon (next few weeks, driver side first) so I'll break out the trusty Ipod with it's awesome microphone and run the speakers one at a time on one side to try to find their cross over values and where they peak at. I should be able to just play pink noise from each and what the highest point on the graph is should be their sweet spot, then I can figure out where they cross over each other and roughly work out what the stock amp is doing.

What's it matter, the stock amp is weak. Well, Toyota picked those cross over points in the cabin of the Celica for some reason, if you can duplicate them with your aftermarket system it really gives you a leg up on dialing it in to sound good because frankly with the exception of the shrill tweeter and lack of strong bass below about 80hz, the stock system is well tuned and sounds good despite it's lack of power.

 

Must be, I've never seen door panels without tweeter locations. I mean yea, the tweeter is just a hole knocked out with an insert stuck in so it would be easy to make one door panel and just not knock the hole out I guess.

Holy hell, tons of options!

Ok, tweeters came in today.

00-02 Premium tweeter is crossed at 8457 hz. 4.7 uf cap with a 4ohm tweeter.
00-02 NON Premium is a 3.9 uf cap for a cross of ~9950 hz.

This seems counter to what I had expected.

Ok 2way, check my math!

 

00-02 NON Premium is a 3.9 uf cap for a cross of ~9950 hz.

Worse than you thought. The 3.9 uf has a -3db point of 10,192.31 Hz. Math on the 4.7 uf is correct. Note also that the 8spkr one appears to be a mylar dome/semi-dome and the 6spkr one looks like a plain cone tweeter.

I doubt there are any chokes in there.
