Hi guys lurking a long time and a owner of a set of 4/5000 with the pyramid cabinets.
Included in my 9.2 system I have an Ohm center, and matching Walsh satellites.
As an Video/Audiophile I did have need for deep, deep infinite baffle bass when needed
so I built a set of subs with four 18" drivers rattling everything including my neighbors false teeth.
As a self inflicted dyi person that can never leave anything alone (ever) ;) I had to fiddle
with the center channel as it really kind of sucked.
Ineligibility was incredibly poor (JS did make some changes to the crossover) I was still very unhappy but figured it would break in at some point but never did. Tried different cables ran Audessey but no avail it still sucked.
At one time I was almost strong armed in to change the speaker by my wife as she couldn't understand some of the dialog ( me too).
Finally my curiosity got the better of me and VOILA' the perforated can over the drivers were removed........Dang that's all I can say, by now you might figured out that all the speakers fell under the knife!!
Before I continue, I will start from the end...
I now think I have something very special that sounds fantastic, were I felt no connection to
the music and movies I now have Air, Transparancy, Intelligebility, amazing Imaging and
sound staging wider that any speaker I ever owned.
I also have to say that JS is a very nice guy who will take care of any issues I ever had
imagined or real...
So anyway back to the center ch, I also fashioned up a horn like device around the
now naked driver. It seemingly helped to throw a more intelligible sound field,
BUT it wasn't right, it started to sound compressed and weird. Out went the horn
and snip, snip.....
The tweeter went in the pile of never to be used again parts.
As a previous owner of Maggie's, and a few electrostatic speakers the idea of adding
a planar ribbon was incredibly hard to resist, yes a planar ribbon tweeter, but it had to be small enough to fit within the 3" or so measurement height wise as I did want to re-use the
grill cover. Parts Express had the perfect driver (after cutting away part of the flange), that met the requirements. KAPOW dang and holy cow, now I can even understand weird British accents and my wife is very happy indeed.
To match the fullness of the 4/5k I added a parametric equalizer to the mix to fatten up the sub 1k frequencies and smoothing of a small 2k room anomaly.
I will have more coming and if it's possible I will post images or a YouTube video in the next few days...🇸🇪
