I used the Tang-Band on the recommendation of Bigfieroman who did the initial research. https://www.fiero.nl/forum/A...090219-2-076432.html

Out of curiosity I contacted Parts Express.

Basics of the conversation went at such. Tang Band Neodymium sub is the best there is for our application. The Ferrite version that I linked to has very similar specs yet has a large magnet which would occupy a large percentage of the air volume in our application thus making it suffer in performance compared to the Neodymium version. The large Xmax and frequency response is what makes the Tang Band good for our application.

I'll be ordering a Neodymium. Someone else will have to experiment.

Thank you. That should answer pokeyfiero's question too.

Not my car - found this video on YouTube - recorded with a cell phone I think.
Unfortunately, a YouTube video doesn't give you the "in the car" sound and feel.

Has any one ever had audio problems with this mod?
I did mine a year ago and it's never sounded right. It sounds great when I'm listening to something like dance music where there are nice clean bass hits but if I listen to rock and roll where there are sustained low tones like a long note on a bass guitar it sounds really distorted. I've tried taking the speaker out of the housing and playing music that I know causes it to see if the speaker is blown but it goes away when I do that, press it back in to the opening and it comes right back.
I'm thinking about uninstalling it and getting an RD speaker or something.

I've done this in 2 Fieros and love it in each one. I was have some cut out problems in one at high volume that turned out to me a short in the wiring inside the enclosure. No problems since fixing that. I agree the neodymium are the way to go

Has anyone actually compared to 2 different models of the TB speaker that are sold? w5-1138sm or w5-1138smf? Seems like looking at the spec sheets that the one which is $20 more expensive has a smaller magnet and is actually rated at slightly lower power? Would that make it just a better match to the low power stock amp, or what am I missing? I was always told to buy the sub with bigger magnet.

I'd think that would have more to do with the enclosure than the speaker. I like Rock more than other types and I never ever use a ported enclosure. I like sealed enclosures and I build my own for a 6.5" sub.

I'm using the factory sub housing. I discovered a couple unwanted noise sources. I eliminated the noise from the vibrating dashboard by jamming a bunch of rubber-polly whatever it's called packing material up in the dash around the enclosure (I also recently bought a new dash and when I install it I'm going to fill some of the empty spaces in the back with expanding foam) and I got a better sound out of the sub by turning my other amp (the aftermarket one powering the rest of my speakers) way up so that I don't have to turn the radio up as much. It's like 70% better but even then it will still sound distorted, even with the volume on the sub volume slider turned all the way down. It's got to be the factory amp that's powering the sub. It could just be that it's 33 years old, worn out, and sending a dirty signal.
And now to figure out how to put a small aftermarket amp to power the sub in the same place in the kafkaesque stereo wiring harness...
