Speaker Mods


Several years ago as a young struggling audiophile I bought a pair of Warfdale Diamonds. I was sceptical when I set them up, but I thought I'd give them a chance. I put an album on and listened. After only a few minutes I was ready to cry. I sold an okay pair of speakers to buy these and they sounded awful. I let them run for a while and since there was no noticeable improvement I realized I had to do something. I don't remember what the cable was anymore (this was about ten years ago) but I opened the cabinet and replaced all the wiring with either audioquest or monster cable???
When I put the speakers back on their stands the difference was unmistakeable. I did a "blindfold" trick with a friend who was also into listening. I played some familiar music for him while he couldn't see them. When he removed the blindfold he was floored that these little speakers sounded so good.
I have since moved on to bigger and better speakers and have thought about doing something with the cable but I'm worried about doing the wrong thing. When the speakers were cheap it wasn't intimidating, now it is.
Does anybody have any ideas about safe mods I could try on my Sony SS M7es speakers. They sound good now but I think they could be better.
Thanks for any insight you can offer.

Nrchy, I will admit I was also questioning the usefulness of a speaker filter before I tried some. I thought it was even a silly idea. However, I found differently. In the case of the Bybees, I searched the web for info, and posted some threads here on the Cables Forum(Check archives for Bybee Filters) I got mixed reviews, but most of the people that liked them thought they were great, and the others said that they couldn't tell any difference. So, really no down side, and I decided to get a used pair for $300. It was like getting a component upgrade or new NOS tubes or something of that magnitude. As you know, I have a fairly revealing, detailed system, and if it was doing anything bad, I'd know right away. But, the best way to describe it was that everything got smoother. Edges and grain that I didn't even think were there, went away. Sibilances gone. Sharper focus. Lower noise. IMO they are worth it, and don't do any harm, just improvement. They were originally a military invention to clarify the detail in long-range underwater sonar systems. They work. Get used ones and save some money, they don't wear out. They show up on the A'gon classifieds periodically. About the stands, if you make a pair that lifts or angles the tweeter to ear height, you can get image improvements,and since you already use stands, you will not sacrifice any bass. If your bass can stand some boost, then you might consider using adjustable spikes to angle the speakers the way you want, and use the floor boundary to boost your bass response by about 3db. In either case, make sure that the speakers have a very solid and stable footing with no rocking at all. Any rocking will cause the speakers to move imperceptibly at higher volumes, causing doppler and cancellation effects primarily on the tweeter. Make sure the construction of the stands is rigid, and the stand does not protrude from the front or sides of the speaker boxes,creating an unwanted relecting surface for the sound. Keep it all under the speaker. Regarding the cables, if you like the Monster on your system, by all means stay with it, and use it inside the speakers as well. The Cardas cable you mention is also good. It is possible that making a felt ring to go around your tweeters may clean up the image even further, but your box is shaped to reduce baffle reflection already, so it may not need it. For about $1, you could buy some self stick felt, cut a properly sized ring about 1 inch wide and stick it on the box surrounding your tweeter. If it helps, great. If no difference take it off, and nothing lost.
Do you have any recommendations for sourceing the needed supplies for rewiring and getting binding posts?
Get your self a couple of sheets(24" x 27") of Black Hole 5.

Remove the drivers and and loose damping material and try
and cover the inside walls of the cabinet. It's easy,just cut, peal and stick(it has pressure sensstive adhesive).

Stay at least two inches from the rear of the drivers.
It will greatly improve inner detail in the lower midrange & bass.

Also, don't waste time with the Bybee filters, get the Bybee
purifiers($40-$50.@) and connect them in line with the postive leads of each driver.

I recently did these mods to my seven year old pre-Talon Khorus speakers and was blown away with the improvements.

Total cost $225.00 and two hours of my time.
