That's the most elaborate turd polishing I've ever seen.

I'm a turd polisher myself. I think you did a nice job.

Nice job but the box should be flipped upside down so the tweeter sits near to the woofer.
I know that perfection doesn't belong to this world but this basic knowledge should be *used*

For all that effort you put into that project, you should have bought a decent dome tweeter instead of guilding the original rather crappy one...

GRS 1TD1-8 1" Dome Tweeter 8 Ohm

Ok. I guess in NZ is not that easy....

I did not want to spend more money, the wife would have me strung up!

yes i was looking and listening today and realised i could have easily flipped the units over, nevrmind.

those tweeters actually sound quits nice. Anyway it was fun tinkering and listening to improved sound out of these things. The audio world/industry is so full of BS! People seem to be so caught up in perceived notions that gear cant possibly sound decent if its cheap. I have long gotten over that, having to use what i have and on low budgets, so no ego issues here.

The modification of yours is really interesting. Good job! I have some Aiwa speakers as well, 4 or 5" bassmid and a cone tweeter. The XO filter is made only of one capacitor for the HP. In the spring time I'll try to build a new cabinet and a completely new filter. I don't see a point in acquiring a better tweeter. I'll use the wood from a cupboard, think it's 14 mm chipboard veneered. We'll see.

Sweet

I actually don't like dome tweeters, I like the paper drivers. I've had expensive speakers with poly......bla,bla drivers and special dome tweeters. I found them to be too crass/harsh.

I only buy/listen to paper. I like the 'chillaxed' sound they give.

Sign of the times... low-end speakers used to have standard catalogue drivers poorly matched to solid enclosures. Nowadays low end speakers usually have drivers optimised (*) for the enclosures, but the enclosures themselves are often little thicker than cardboard. You can get a significant increase in performance by transferring the drivers into a solid enclosure and using a proper (though basic) crossover. You can also take the opportunity to tune for a flatter bass response rather than the hump often used to give the impression of more bass.

(*) For typical mass-produced mini-systems, with modern design software it costs no more to have a driver built to specified parameters than to accept an off-the-shelf item. The enclosure determines the driver parameters, rather than the other way round. (The enclosure size is usually chosen to match the size of the electronics unit.)

Im not up on all the techy side of things. I did not want build another enclosure, too much money.

These were just messing around, but the improved sound is quite remarkable considering the components used.

I have had Plasticine on my Hawthorne OB's for a few years now and are completely sold on the improvement to them, so was keen to try something else just to confirm this theory. And that Plasticine has stuck hard, no issues what so ever. Could have done a better job on them, but its all about the sound.
