Minimus 7 mod-check my work?

Based on what I have read here in the many Minimus 7 threads, is this a reasonable mod?

I have seen a few diagrams, some similiar, some different. Some say the inductor is the wrong value in some of the diagrams posted on the forum, etc.

This diagram was "borrowed" and modified from one of the "correct diagrams".

Thanks, YD

Did you read my Minimus 7 thread?

We checked out most of the known mods there:

I believe I also tried what you are suggesting, but if I did not document it, I can still do that for you.

Post in the thread if you don't find what you need there.... :yes:

Zilch...i could your help

I could use your help

Can I PM you?

No I have not read that thread, and I have searched this forum using the term "Minimus 7" a few times. Not sure how I missed it.

I am basing this very simple mod on a post in one of the Minimus 7 threads (I'll be damned if I can't find it right now, but I am looking).

I don't know who said it (yet) and I don't want to misquote that person, but, it was something on the lines of " if you move the inductor over to the woofer, and upgrade the cap to a higher quality cap of the same value and run that to the tweeter, then this mod will give you about 90% of what improvements the ebay mod can give you".

Once again it was something along those lines and when I find the actual quote I will post it. I dug up a few solens of the corret value in my junk drawer and just decided to give this a try, but not being an electronics guy, I thought I would post the description (diagram) here just to make sure I was understanding things correctly.

This is not an attempt at a full blown redo, more like a "lets see if it helps" type mod.

However, thank you for posting that link. It will be this evenings reading material. YD

"Although I do have the schematic for the upgraded crossover (and I'll try to get it posted later for those of you that are interested) the easiest thing to do is just move the original coil from it's parallel connection on the tweeter to a series connection with the 'woofer', and then replace the original 4.7uf electrolytic on the tweeter with a decent film cap of the same value (still in series). That'll give you a simple 1st order filter on both drivers and a reasonable amount of protection for the tweeter. Moving the coil to the woofer and replacing the cap on the tweeter with a Dayton metalized film cap or similar will probably get you about 90% of the improvements that the upgrade crossover from the guy on eBay will, and you can do it for about $3"

That quote came from this thread, post #65: http://audiokarma.org/forums/showthread.php?t=66858

Well, considering what the eBay kit does. :tongue:

Read up. You're close to the second-best solution. :yes:

[Well, third-best, then. O.K. fourth-best.... ]
