As many of you may know, I installed the Elduderino Speaker upgrade. Here is the writeup on that: TSX audio upgrade Phase 1 done

Well, I went back to get my sub installed, and Elduderino wanted me to try a new set of speakers in the fronts. These new speakers sound great! They fill in a bit more of the low end that the stock head unit puts out. Now, I'm not saying these sound better than the original Elduderino tsx upgrade kit, but there is a difference. The highs are not as defined as they were before, and I can hear the tweeters much more clearly than with the other speakers.

This is the first set of speakers that I've had that I don't think that a set of rear fill speakers are needed. This really surprised me. I still need to go back and get my subwoofer installed, and I'll have him turn off the rears so I can hear the difference since I'm far to clutsy to do it myself.

As far as the specs on the speakers, You'll have to ask ElDuderino. I'm no audiophile, i just know what sounds good to me.



[disclaimer]
This review is late and long coming. These speakers were installed about 2 months ago, so i do not know about the availability of these speakers. Between 2 kids and a data center move I've got very little time to just sit on the computer. Sorry it took so long for this write up ElDude.

Two months ago huh? That's about when elduderino disappeared from this site. Check your trunk, maybe he's locked in there.

 

^^^^^......the mystery continues........

Sounds like a case for the x-files!

 

from what i hear....hes doing really well with his new store that he opened. so thats why he hasn't been on AZ

 

That's what I figured. He was always busy when I contacted him.

 

Pilbox,

Are your new speakers 6-1/2" or 5-1/4"? Eldude's Avincar door speakers are 5-1/4" because he couldn't get the 6-1/2" ones to fit the TSX door. I wonder if he found another manufacturer with a shallower speaker. Theoretically a 6-1/2" would be better able to reproduce lower end than a 5-1/4".

jlukja, who is very happy with his 5-1/4" Avincar kit but is curious.

 

Cjams, who is very happy with his Infinity 6-1/2s that fit perfectly

Still think he's skerrd to show up here anymore.....don't think he tries to convince peeple that walk in to his shop to butcher their wires anymore

 

The new speakers are 5 and 1/4.

 

what do you mean by that.

 

Well my front pass. side door speaker sounds like it's blown so I was thinking of replacing it with the avincar upgrade but if he's not around...

 

check out his website at www.avincar.com and give him a call if you're interested. He apparently stopped frequenting this forum but he's still doing business. It can't hurt to call him up and ask him if he is still offering the avincar upgrade.

 

I hope Avincar is still shipping this kit (or an equivalent one), because I think it's a great solution. They definitely need some break-in time, but you can immediately hear the increased detail. After a bit of tweeking, I am *REALLY* enjoying them! I think they are a great set of speakers! I can't imagine how much you'd have to pay for better speakers, and then you'd probably need an amp.... I'm pretty happy with the stock amp; rarely do I want more power, but I can see where it might not be enough for some. But I think this is a fantastic setup for those who don't want to mess with an external amp but still want high quality and even low bass.

ed.duderino is over on the bimmerforums. lol

 

what a traitor!

 

Oh, I go lots of places...

Promised my wife I wouldn't spend any time on the Acura forum for a while. Didn't say anything about bimmer, G35, or 300C : )

 

He's alive!!!!!!!!!!!!

 

Hey man! How u been? How come the wifey says no Acura forums?

 

While 6.5s usually offer surperior low end responce, keep in mind that the smaller 5.25s generally offers better off-axis response. That means the midrange output from the smaller speaker is likely to be better.

 

Do your AVINCAR separates really just utilize a single cap on the tweets? Why not a second-order crossover? The only negative would be cost, but we're only talking a few dollars.

 

Why not 3rd or 4th order? What does it matter? One isn't inherently better than the other, and we don't even know the crossover point.

 

It's a reasonable question!

My understanding is that this is just if you are using the factory amp. Having a 2nd order xover would sap more power, and you only have so much power to work with! The single cap is a good quality one.

 

A crossover limits/attenuates the frequencies that a speaker will reproduce, it doesn't utilize any power. The order of a crossover in absence of a crossover point and a given speaker is essentially meaningless, because you have no way of knowing if the speaker can adequately reproduce the frequencies. Any particular order could be better than others it depends upon the speaker and the crossover frequency.

 

My avincar speakers initially came with the crossover capacitor for the CL. When I switched that one out and used a 4.7uF capacitor the sound really improved. I now have my settings flat whereas before I had the trebble set at (-2). Don't know what the crossover frequency is nor do I care what order the crossover is or what slope. All I know is, to my ears, they sound fantastic.

That number seemed way too small, but then I realized that these tweets are connected to the factory amp, which has it's own caps (now I'm gonna have to open it up again, I'm curious). Any idea what the CL kit cap was rated at?

 

Okay, I read it, but I'm sorry, I don't see what you're getting at.

 

 

If I understand correctly, Eldude uses just a cap (1st order crossover) so as to introduce as little loss in the signal as possible.

 

The cap is to set/adjust the crossover point and there won't be any signal loss within the passband, outside of it, yes, but that's the point. In absence of any other information (crossover point, speaker characteristics, etc.) a 1st order xover isn't any better or worse than say a 4th order.

 

As an example, inductors seem to have a DC resistance. Does this not affect inside the passband? Even a 1st-order low-pass would have to pass all of the signal through a lot of wire in an inductor, which should have some sort of effect even in-band.

With enough amplification, it wouldn't matter. Unfortunately, we do not have enough amplification in this situation, which is the point. How much is .3 ohms worth?

I don't think I would have thought/considered this point until I saw Elduderino's explanation of his speaker kit. So, if I am completely misled, I'm blaming him. ;-)

 

The one I took out had 335K stamped on it.

When I told elduderino that the dash tweeters seemed too strong (even after break-in) he asked me to look at the crossover cap, said that the TSX kit should be 4.7uF, and said that he might have shipped the CL kit by mistake. I assume, therefore, that 335K was intended for the CL kit.




On a side note, the TSX now has a better sound than my home system. Damn it. Having heard what good speakers sound like I'm now shopping for better speakers for my family room.

 

Ha, holy shit! Learn something new every day... I was about to write that, that sounds like a part number or something, but I figured I'd google it. Turns out that there is a capacitor code, much like resistors. I never knew that, I've only seen the value printed on them. Anyway, I didn't even need to do the math, it was at the bottom of the page, 3.3 uF.

Hey, thanks for posting that. I was hella curious about what 335K really meant.

This is the one I used

 

Do you even understand the difference? After all until just recently, you didn't even know how to read a cap.

 

The 3.3uF cap would give you an 8kHz crossover point, while the 4.7uF cap would yield about a 5.6kHz crossover point. You could get an even wider range out of that tweeter by using a 2nd order crossover (and crossing it over at 3.5-4kHz), but you might sacrifice some overall level depending on how expensive of a cap and coil you get.

 

Let me caveat that -- this is only true if the tweeter has a nominal impedance of 6 ohms (but there is a good chance that is true). If they are 4 ohm, then the 3.3uf would be 12kHz and the 4.7uF would be 8.4kHz.

 

Bit me dude. The caps I've ever seen/used have all had the value printed on them, not a code.

Also, in your crossover point calcs you aren't taking into account the 2 uF cap in the factory amp that is inline with the tweeter output, nor the actual crossover point from the factory amp ICs.
