new beetle convertible- crossovers

[cirus]

hello to everyone, I am Italian, not speaking English(google traslate;-).
I want to know where the crossovers are located (front) of NBC. Thank you.

anyone help me?

I think Crossovers is not the correct word. Can you try another word or translator?

Welcome to the org!

[cirus]

thanks for the welcome.
Crossover is a international word.
the Crossover is an electronic device;he divides the high frequencies to low frequencies end redirects them to the tweeter and the woofer respectively.
The simplest crossover for the tweeter is a capacitor, for the woofer is a inductance(6db/oct).

The crossovers illustrated into the picture is:
12 db/oct slope for the tweeter;
12 db/oct slope for the midrange;
6 db/oct slope for the woofer.
thanks.

Much better post! Sorry, I know nothing about audio equipment. At first, I thought you may have been talking about signal lights! Was I ever wrong! I hope someone here can help you.

I'm sorry, the crossover is not a graphic(numbers displayed are a form of graphic representation) equalizer. n an audio system there is always a chain:
source (for example the magnetic head of cassettes unit)-->
preamplifier unit (operate a small amplification of source signal)-->
equalizer unit(emphasize or de-emphasize high, medium and low frequencies depending on the tastes of listener)-->amplifier unit(creates the voltage/current appropiate to driving the speaker system)-->passive crossover-->speaker system.

If there is an active crossosver is positioned between equalizer and amplifier.
you note that the active crossovers work with small signal(0,6Volt to 6 volt) and passive crossovers (for car-audio) work with big signals(12V onwards).
the picture is a three-way system with passive crossover.

I'm not sure if there's actually a physical crossover device separate from the speakers for the Bug. If I remember right I believe the crossovers are directly attached to the tweeters and are just as simple as ones that are on a standard 2 or 3-way speaker (non-Component), about the size of a resistor. That is the way it was on mine, but I'm not sure how it's all done with the monsoon system, they might handle that inside the amplifier.

What are you wanting to do once you find the crossover? If we know what you're trying to do it might be easier to help you get the answer you need.

I think that the crossover is part of the Monsoon Amplifier.
On a non-convertible it is located in the rear hatch. I'll have to see if I can find a picture so you can check.

Check out this thread. It might have some information that can help. The location of the Monsoon amp in a coupe is pictured on page 2.

I saw another thread that stated it was in the trunk under the rear deck...but I really don't know where the amp is located in the convertible.

Hello,thanks primarily.

I understood. The system has a crossover for the tweeter formed by a single electronic component, which is a capacitor. It has a slope of cutting 6db/octave.
Instead for the woofer is exploited his inability to reproduce high frequencies.
For the woofer, in the picture above, the factory says the frequency response from 40Hz to 5000Hz.
For the tweeter the speech could be similar, except that it is necessary to cut, given that low-frequency it breaks.

What are you wanting to do once you find the crossover? If we know what you're trying to do it might be easier to help you get the answer you need.

I want replace OEM siste with the system in the picture above.
I want to know how the wiring is done. So i can decide whether to leave or replace the original cable.
Thanks.

I am glad to have found some information.Thanks thanks thanks

On every newer sound system you'll find crossover integrated inside stereo unit, and separate output wires for tweeters or large(r) bass speakers. Crossover is separating high, middle and low frequencies from speaker output signal and sending them to appropriate speaker. In the old days you would find crossover inside 3 system speakers, but nowdays they are "not that important" and low frequencies are being separated only for Sub Woofer while other speakers reproduce full frequency range and sound crappy. I miss the old days of real HiFi
Back to topic You can use any existing speaker output signal and add crossover for any size speaker and frequency you want. Where you will physically install crossover is up to you but I would keep them as close to the speaker as I could.
Good luck!

I do not have a monsoon system.
I have the OEM VW Blaupunkt Gamma (http://special type for NB) with integrated amplifier (4x20W) and cd canger OEM and 10 speakers.

thanks

I disagree! In car audio system with small amplifiers integrted in the source the outputs are only FR,FL,RR,RL.
If the speaker system is formed by full range speakers ok, but if have a system of components a minimal crossover is necessary.
Even in complex systems multi-amplified with external amplifiers
the cut of frequencies is operated by an active crossover and a amplifier for trebles, a for mid a for woofer and a for subwoofer. In home audio is the same. An example is the system 5.1(5=2 for front stereo speakers two for rear stereo speakers and one for central channel)(.1 is hte one subwoofer).
In high-end system exist only 2.0(front stereo speakers, each is made up from tweeter and mid-bass).

A good crossover ( active or not ) is necessary if you are going for high fidelity sound in any system. Integrated capacitors are a joke just like 5.1 speakers are You need 2 speakers to hear everything crystal clear ( use Yamaha NS10 for best results ).
The point is, you need to install crossover cause there is no proper one, but to actually hear how it works, you'll need super quite car interior, custom speakers setup, high end wires, very high end speakers, high end amplifiers, high fidelity analog source and a good pair of ears. Digital sound can't take you where analog would.
Factory 40Hz bottom frequency response for the woofer is a joke too You don't need a crossover for that. Heck... you need no woofer at all.

It's personal choice. I like to listen to my engine while driving and have some low level music in the background. No point in investing too much for that. At home it's a different story.

What I have done in installations I have done is use the existing factory wires. Since VW uses the speaker mount as the crossover position the wires are all there and the new crossover can be hidden in the dash. This was how I did the install on my Cabrio, have not done this on the beetle but it is the same concept.

Many thanks.
it is precisely this type of information that I tried.
For example the experiences of others who have installed aftermarket speakers.

In my system the only thing I'm using from the factory harness is the power wires, illumination and ground wires. From my headunit I have three pre-outs (front, rear, sub) and use those with two 600W amps. Front and Rear share an amp which powers a set of components up front and a set of 2-ways in the rear, All completely new wiring just for them. Then the other amp is used to power 2-10" subs. The way I filter the signal so only the right sounds go to the right speakers is. In the Headunit i can set filters for front, rear and sub, so i set them there. Then i use the highpass and low pass filters on the amps. Then finally the front ones have passive crossovers to filter between the mid and tweeter.

Your system is fantastic! yuo have posted 2 or 3 pictures?
I wont to realize a similar system.Step by step ...
First i wont to change the speakers (and crossovers), then the wires, then an amps 2x150+1x350 and a sub 250mm dual coil.
I already have the woofers and the subwoofer, I have to buy the rest.

[cirus]

OK, try to give some conclusions.
This is the original system with 10 speakers?
Grazie. Ciao.

[Basher]

That looks correct, yes. The only thing I'm only 97% sure is the cap for the front midrange.
