Further working on the Fortress Plus builds, trying to further smooth out the upper sections and I am liking the outcome of this layout.
It is also interesting to jam pack all of this on the plates. The Plus builds are a little tough

Hi guys, I did this mod to my RTiA7's about two years ago. At first I noticed they sounded a bit smoother but I wanted something better, so I upgraded and the Polk's went out into the living room system where the TV is. I started listening to the rock station on cable about three months ago, so they've been getting a lot of hours on them. Well, I am now a firm believer in capacitor break-in. The speakers sound awesome now across the range, most notable is the deeper bass and the smoother highs. I guess good things do come to those that wait. Thanks VR3, camaroguy.

So the rumors about hanging up the soldering iron are false?Up

I never said I was hanging it up, I just said I was cutting back on it, I don't mind doing one off builds. I really enjoy Fortress Plus/V2 and my Monastery builds. Right now I go case by case and I only take on projects that maximize my time. Essentially, really small projects don't make sense for me yo do but doing what would average to 8-10 big projects a year, I feel that is where I am comfortable with.
I wont be as active I was before, I was doing 50-60 a year previously where as I have cut it back to that 8-10 number.
I still really enjoy doing it, just to much going on for me to devote the time I was doing before.- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
^So what your saying is.... if I dropped off my entire 5 channel LSi setup you'd be more likely to take that on then say a single set of speakers hehehehe...."....not everything that can be counted counts, and not everything that counts can be counted."

So something we experimented with these on after the fact was cutting out some lows in the midrange. We tried a hand full of values to put in front of the inductor in that circuit and the results were positive. I may offer this as an optional tweak in the future...

So it would raise the crossover point of the mids or attenuate the lows?Up

The 100uf cap before the mid inductor rolls off the lows from the midrange driver. I have not personally heard or experienced the results, but the owner is extremely pleased.- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.
