This thread is focused on the OEM HiFi speaker option - which admittedly your car is not equiped. GF

That doesn't sound like the 5.25" JL Audio speaker I tested. Maybe you do have the 6.5" version. I wouldn't be surprised.

Just curious which focal component that's being used............

Thanks for the welcome.
I have had a bit more experience on the non hifi option but have done a few cars with the hifi option.
So from the above the 3" is playing full range from 20hz to 20khz.
Should it not run from 500hz up. If not I would put some sort of xover on it.

I am running Focal KRX2 with a JL Audio 8W3 sub in the glove box running from a JL Audio 900/5. Even without the sub I get very good kick and sounds very clean. The sub is just there to fill in the lows below 50Hz at a 12db slope and does a great job.
For the hifi option it depends on if you are using the factory amp. If you are you need low power speakers around 50watts. It is never good to underpowered a speaker. Hertz do good speakers that will sound good in the original pods. If you go down the route of changing the amp and fit more powerfully speakers you will find the pods internal volume is a little small and will give you mid heavy sound and also resonates the door panel which will give even more mid. This can be improved by stuffing the Pod with Polyfill (the stuff pillows and toys are filled with) I'm not sure of the internal volume of the pod but you need about 16oz per Cubic foot. This will make the speaker think the pod is bigger than it is and give much cleaner bass response.
The brands I have tried and had good results are
1 Focal
2 JL Audio
3 Hertz
4 Audison.

Just a few tips on getting better sound from a 993.
Mount the speakers to a solid base. Dynamat the door pod to make it a bit more dense.
Fill pod with polyfill.
Turn off the loudness on the stereo
While setting up you system start with all you bass and treble at zero, use the volume to get the mid at the volume you want and then add or reduce the bass and treble to suite (yes you can turn them down. Lol)
Use a good quality cd recording to setup your system, don't use the radio or mp3 disks or players. Dont use compilation CDs as these are normaly compressed to get more tracks on the cd
If you do the above you can get ok results from the factory speakers.

If you after sound quality I would disconnect the rear speakers as they pull the sound stage to the rear of the car. I also think a sub really helps for sound quality, it's not there to set off car alarms or rattle the car to bits it's there for filling. If you have a surround sound system at home try turning of the sub

FWIW, I installed the JL Audio speakers a couple of weeks ago and noticed a nice improvement. I'm not an audiophile so it doesn't matter all that much to me -- but the sound is definitely improved.

Here is a pic of the sub box I made to replace my glovebox.
Ignore the colour of the lower dash section and the wires hanging out the bottom of the dash as the pic was taken with a spare dash section while I was building the box. The install is 100% reversible if I ever want to take it out.

Just again if changing your speakers I can't recommend filling the hifi pods with polyfill enough, very cheap from Walmart and a big improvement.
Non hifi option fix the speaker to the metal of the door.

BAJ - Very impressive and nice use of space allocated.

Luv the creativity! Now yer talking & entirely stealth.... and its 100% reverseable. Ding, ding, ding, we have a winner. If you don't mind I'd like to share your 993 sub/glovebox install with a few professional mobile audio installer's on a web site http://www.diymobileaudio.com . those guys will applaude the effort! Are you using the P-99RS as a head unit? Herculean DSP signal control the P-99RS.

Gotta zooom for now.... a little later on the enhancement to the stock HiFi option on the 933 (911) car. Gotta zoom.

Baj

At the moment I am using an Alpine 7998. This will be changed to something that will fit in the dash a bit better. I might go for a p-99rs but I have got my eye on Mcintosh head unit.
Mike, by all means you can post the pics of the box. I have pics of the complete build if you need them. If you do post them could you PM me a link to the post please.
The glove box (front kick area) was the best position I found for the sub. I tried behind the front seats and on the back seat, but both these positions it felt like the seat was being kicked from behind.
Blends very well with the fronts now too

For a few pictures of a Pioneer DEX P99RS head unit in our 993 cars do a Rennlist search using this thread text; "HiFi - Dynaudio - DEX P99RS head unit - pictures". The pic's are of my 993s interior.
The P99RS asthetic fits the our old sckool dash pretty well - although not the established appearence of the OEM radio I'll give ya that.

I'll PM you my mail address for the complete "build" pic's. Once completed the link I'll get to you.
What a cleaver sub-bass solution where its not kicking the seat backs.. ! Priceless.

Mike,
Just received my Dyno' 3" midrange. Have to cut off the VW connector which leaves a black and a black/white wire. Do I assume the former is negative and the latter positive?

Baj

To be sure you could connect a small battery to the speaker, a AA or AAA battery normaly works great.
When you get the wires the the correct way around the speaker cone should move out, if it move in the wires are the wrong way around

M. Schneider

The white striped lead is + positive if I recall.

Like Baj ^^ mentioned, take a 9v transistor or other battery and momentarly connect the two leads to the speaker, when the initial connection is made, which ever wire is on the batteries + terminal as the the speaker cone moves outwards is the + lead. When the leads are reversed the speaker cone will move inwards.

Do me a favor, after the 2 new each door speakers are installed, listen to the stereo system without the speaker grill / carpet covers on. The grills mask or muffle the sound stage efforts (audio output) a great deal. I'm working on an elegant DIY solution as we speak.

Good luck, I'm anxious to know you're thoughts with the Dynaudio 3" mid in the system. Go easy with the level as the signal to the OEM 3" speaker is full bandwith; the HiFi options Nokia external amplifer doesn't have enough output power to effect damage. As with the OEM 3" speaker, the frequency roll off will happen naturally on the low end and on the high end,,, above 4Khz or so.

The CDR-210 units bass tone control is centered on 100hz, prolly + or - in 2db increments or so. The loudness contour can go either way...mine is OFF.
The system really would benefit from proper EQ, crossover slopes and modern amplification,,, but were not there yet.
Good luck!

For all of you who just want an alternative to the front door junk Nokias but don't want to spend a fortune upgrading your entire system, I found a "comfortable" solution for replacement. Keeping in mind, these are only a replacement for the lack-luster sound on a non-hifi 993, for about $60.00 or so, buy a pair of Infinity Reference 4032cf, 4" two-way loudspeakers. Remove present stock Nokias, cut the trim ring away from the speaker cones and magnet. Drill holes in the trim ring, ( the one that the stock grill snaps onto), get spacers and bolts at your local hardware store and mount the 4" Infinitys onto this ring. Once mounted install entire unit back into door panel. Voila! The stock grills just snap back onto the old speaker rings. I used a lot of foam to take up the small gap around the 4" drivers and the old trim ring and also used foam in the door to help dampen the sound. Although this is only a "bandaid", when it comes to improving the system, I find that it's a significant improvement over the original setup with the Nokias. Yes, the drivers are smaller, but I like the improvement in sound and they still look stock. Since I didn't want to spend the "big bucks", this will get me by, 'til I am ready to cough up the dollars to do a complete system upgrade.

Sorry to resurrect this old thread, but I'm in the process of replacing the stock OEM component speakers on my hi-fi optioned 993. I did a lot of research and thread scanning and decided to keep the OEM component mid & tweeter, but replace the 5.25" speaker with the JL Audio C5-525 (I want everything to remain as stock as possible). The rest of my system is completely stock (stock amp and becker cdr-210 head)
My questions are; since the Dynaudio VW 3" mid is virtually impossible to find these days, has anyone found a new option for the mid-replacement?
And secondly, I'm a bit disappointed in the sound coming from the 5.25" JL Audio speakers, it's muddled and unrefined. Did I do something wrong on the install? I can't imagine I did, just swapped out the speakers one for one? Has anyone else experienced this? Am I missing something??
Thanks,
Rob
