Diffraction elimination

[jimdgoulding]

jandl100- Thought I would give you the information I think you need right here in front of God and all these POTENTIAL BUYERS here in the forum. It’s how I market. Never said I was the quiet type.

The large pads for your mid drivers should fit admirably and in keeping with your requirement to be able to return your grilles. The small pads for your vertical ribbons are more interesting. I’m hopeful that you have as much room between your mid driver and your tweet as it appears in the pictures. I want both drivers to be able to be precisely centered in the cutouts. In case I overshot it, you can trim a little of the bottom of the surrounds for your tweets. This wool, unlike what I normally use, is pretty manageable with a good pair of scissors. Not really knowing how wide to make the cutout for your ribbons, I included a couple of bars that can be tucked inside of the vertical walls without adhesion to narrow the width of the slot for you to play with. I’m thinking they may be desirable but you can be the judge.

I enjoyed making these for you. I hope they help make your system communicate music more directly.

.... have you shipped them yet?

I see you've ordered a set Jerry - you'll not be disappointed mate.

I'm sure he won't be, and let's see some nice pics and a full write-up of the product (in the Strokes of Genius section) when it arrives

yes, it'll be interesting to see what the pads do ..... I must confess I'm having some trouble integrating my new ProAcs into my room. Imaging is a bit big and blowsy for my tastes.

I don't think it's the speakers themselves, just the way I prefer to have speakers set up - for various reasons I fire them across the width of the room, not down its length and the open baffle nature of the ProAc's mid and top is causing problems with being too near the rear wall, I think.

I'm not sure that Jim's pads will help much with that.

Open baffle designs are I think much happier firing along the length of a room, as the side-ways sound cancels out and you get a distinctive figure-8 radiation pattern. So they are good near side walls but not rear walls

I might try turning everything around by 90 degrees, but tbh I don't really want to do that!

They work mainly in the mid and lower mid/upper bass area and really help to focus vocals and low mid transients (like snares etc). However I did notice a marked improvement in imaging although it was more than likely to do with the act of decongesting the mid/low mid/upper bass rather than outright problem solving.

Still, you'll be impressed and they may just do the trick. Certainly I will never go back.

And no, Jim doesn't pay me to say nice things about his product - it's simply an outstanding product.

Hmmm ... OK ... a bit of focussing in the mids might just do the trick!

Come on, Mr Trans-Atlantic Postman, get your finger out!!

Jerry- I wouldn't hesitate to move your speakers were it me.

[jandl100]

OK - speakers now rotated thru 90 degrees - see photo below (Cripes, what a mess! - I've tidied it up a bit since taking the photo ) and yes, it works! Imaging is good now, along with all the rest of the great things these speakers do. But what the hell do I do with the plasma screen now?

[jimdgoulding]

That's sorta how I have my own speakers set up minus the clutter. I have an open legged not bulky sofa table behind my speakers on which sits my digital front end and linestage. I bring my TT in when I listen to records and then take it out when I'm not. The more open the room to soundwave propagation, particularly the front end of the room, the better for the development of imaging and space in my experience. I can appreciate your concern for your widescreen TV and equipment rack on the side wall. Best of luck.
