Re: Crossovers - where to start?

I had a pair of Clarity Caps (large size, Red color) 3.9uf so slipped them in (removed the 4.7 tweeter cap).

That was a large improvement, a much sweeter sound. I don't know, some say caps don't make a difference but some swear by them.

E.g. SR71s use them.

Re: Crossovers - where to start?

New idea - going to move xo point way up.

Going to use xo design from here and use Vifa X25s

Re: Crossovers - where to start?

This is working well (not much to look at) well balanced, light/delicate, with great bass.

Re: Crossovers - where to start?

It's good when you get a system that works well.
Although, it's the ultimate never ending story....

Silence is golden but duct tape is silver.

Re: Crossovers - where to start?

The smartest thing I did yesterday was to add small terminal bock for the 1st tweeter resisitor - now it only takes a few seconds to try different values and levels.

Settled on 3.3ohm.

I should mention, when I 1st looked at the xo circuitry I was but it's not bad at all (and why started this project)

Re: Crossovers - where to start?

Another front flare project, 2 days to get box tuning right, 3 day total.

Drivers: 6.5 Silver Fute / Vifa X25 in a 13 liter box, tuned to 50hz.

I have a few ides for a xo (my Achilles' heal). Getting some rice sound using xo that I've been using for another project, sounds good, not perfect, but need to break in speakers anyway.

I'm going to give Madisound a buzz, they have these drivers so they can provide a xo design, $30 I think.

Re: Crossovers - where to start?

One more pic and thanks to the Moderator!

The "vents" are 1/2" MDF. I was in laa-land thinking to cut them all at once.

I made up a simple pattern and cut them one at a time (screw holes are not an issue so a little easier)

Pushing these boxes, gesh they have really big bold, box sound!!

Re: Crossovers - where to start?

Back to the beginning - used a new xo for the Silver Flute project - used a muti part xo for the X25 tweeter (never sounded better) - and a filter supplied by Madisound for the woofer.

Which is same as xo design chart 1.8 coil - 7uf cap.

I did place an order for a full LEAP design.

Re: Crossovers - where to start?

You should have a nice set of speakers when you finalise the setup.

What subwoofer are you going to use with them?

Re: Crossovers - where to start?

Not going to give in without trying several xo's! My buddy can measure, but I get a headache if speakers don't sound right

Getting good amount of bass now, but have 5 of these (PIC Below) in different combinations, i.e. folded and single fold TTQWT (sub woofers) The single folds' are 9" wide.
