Hi all,

I was poking around my stereo system on my 1992 400e this evening. I am purchasing a new stereo and speakers and wanted to verify what will fit in the factory locations.

When I removed the two front speakers, they are 4 inch by the way, I saw a capacitor inline with the speaker. I knew that this was inplace to act as a crossover for the small 4in speaker. I figured that since I will be replacing everything, why not remove it and see how it sounds.

Well a simple snip and about 10 seconds of soldering and WOW. I could not believe how much better the stereo sounded. The speaker sounded much better.

The capacitor was a 33uf, so based that this was a simple 4 ohm 6dB crossover, I figured that the crossover point was around 1.1k or 1.2k Hz. If you plan on keeping your stock "premium" Bekker tape deck, you might want to give this a try.

Simple operation, but the results are very nice. The speakers have a rubber surround, so they should be able to handle the extra bass with no problem.

Thought I would just share with everyone my discovery for the night.

ACK NO!! DONT DO THIS !

The main speaker gets full range.... what that capacitor for, is, yes, a high pass filter at 1.1 - 1.2K.... for the TWEETER. Look in the middle of the speaker, and its a coaxial device with a tweeter in there.

1.2K is far too high of a crossover point for just a 4in driver, it must be for the little tweeter in there.

Hate to say it bud, but your tweets are probably roasted.

Brian,

Nope, the speaker is NOT a coaxial speaker. Just a simple full range driver. The cap is (or was) inline with the main speaker input.

But EVEN IF this was a coaxial speaker, the cap for the tweater would STILL be located further inside the speaker so it would only filter the lows to the tweeter and not to the mid/bass driver as well.

This is a US Spec 400e, so the stereo system may be different in the UK. But still, the location of the cap would still only pertain to the mid/bass driver.

Thanks for your concern, but I do know what I am doing. I don't just remove things without proper analysis of the affect it will cause.

Hmmmmmm odd that a 4in driver would have a 1.1K highpass.... its not gonna be doing a lot above about 900-1Khz.

The crossover cap for co-ax tweeters is often glued to the side of the speaker, and daisy chain off the main terminals, thats what it sounded like you removed.

Sorry for the misunderstanding...

Brian,

No problem mate! It is difficult to explain things in such few words.

Cheers!
