Well, when the woofer is 5dB less efficient in the mids than the original... things are not going to be pretty.

Regards,
Gordon.

These are by far, the best looking and best sounding speaker mods ever.

They should have pooled the money spent buying eight small horn tweeters, and just bought ONE bigger horn/waveguide with driver, to fit in the space that's completely unused in the top bay of the cabinet.

Of course, some other woofer than those JL subwoofers, would also help a lot. Something with a lightweight paper or similar cone, anyone?

It could have wound up the "poor man's Altec 19"- but alas, just no...

Regards,
Gordon.

Man, if they had only used one EMIT and put it inline with the midrange (vertical line), that could have been a pretty high-performance thing.

Regards,
Gordon.

They could have used one Emit, offset to the inside edge of each cabinet. That would have made more sense that 2 separate tweeters, mounted in a horizontal line, app. 8" apart?

Can you say



Comb filtering?

I don't think that that EPI disaster can be blamed on puzzlecoat. I experimented with similar damping compounds, and it is perfectly possible to apply it so that it looks like it came from the factory. Whether the damping is a good idea is a different question, but even bad ideas can be implemented well, and equally, good ideas done incompetently.

Well at least the previous owner tried hiding this upgrade. Looks normal on the front. Then on the back we got a Polk tweeter glued to original vifa diaphragm. No wonder why they sounded overly muffled and veiled. A tweeter playing through a tweeter. Gotta give em an E for effort.

What were they? ARs? I've seen those clear poly woofers in the Parts Express catalog years ago.

Picked up pair of really nice AR2a's in Dayton a couple of years ago and the guy gave them to me. He wanted them gone and I thought I could harvest some veneer from them.

Wait what, were they both hooked up??

Just the Polk tweet was hooked up.

 

[Bassblaster]

Funny! Look what I found on Letgo just now.

Does this count?

I bet those speakers have a warm sound.

This JBL L212 "improvement" (long since broken down and sold off) always left me scratching my head:

I understand the head scratching, but I do like the looks of the stands they're sitting on.

These were on eBay a while ago and I wanted so badly to restore them to their former glory, but definitely not for the asking price.

Modded Sony SS-M3s

Let's keep this thread alive.

What, no oval woofers?

 

[Ds2000]

My Marantz Imperial 5G high school upgrades. Bought RS woofers, sock stuffed and sealed the port. Then my sister used them and a cat tore the surround, so white rtv filled the hole. Eventually I’ll frankenspeaker them all the way.

 

[toxcrusadr]

So, 1/3 no surround, 1/3 rotten surround, 1/3 woofer permanently glued to basket? Got it. Should sound at least 3/3 excellent!
