Rustar Posted January 22, 2016 Share Posted January 22, 2016 Mine's getting worn at the edges. Has anyone attempted to replace theirs? I looked at Jokeyman's mod thread, but I hope someone has specifically done this and can advise as to it's dificulty. Thanks to all Quote Link to comment Share on other sites More sharing options...
Jokeyman123 Posted January 22, 2016 Share Posted January 22, 2016 Good morning Rustar. I can tell you it is certainly doable (Is that a word?). My covers are holding up well, but then I've kept this almost entirely for home use and recognize the cloth fabric can be pretty easily worn/torn/stained. Each speaker compartment can be separated from the middle control panel assembly and the main frame of the keyboard base. I forget details but I have completely disassembled mine and it can be done if you are careful and pay attention to the plastic anchors for all the screws which can easily strip if tightened too much on reassembly. I seem to recall 3 main sections to the top frame-the middle control panel and speaker compartments are 3 individual assemblies. The cloth covers are glued/fastened pretty thoroughly around the plastic frame for each speaker compartment. There are 2 screws on each side up high in the frame after you take off the end caps that keep the speaker compartments in place which you may initially have a hard time finding in addition to screws underneath and the end cap screws which need to be removed. You do not need (I think I'm recalling this correctly I'll have to check my own pics!) to completely take apart the PX350 to get the speaker compartments in position for recovering these. I would think the difficult part will be deciding how much of the old grill cloths to remove before recovering anything. The top-firing speakers are very small and the rear-firing speakers are not much bigger-so most of the grill covers are covering the plastic frame surrounds rather than the speaker openings. If you replace with black cloth-it must be acoustically transparent obviously and the black will mask the old cloth (I think). Might be easier to just (carefully!) cut away the areas around the speakers before recovering everything so you don't have to completely cannablize all of it which might get kind of ugly if you can't easily remove all the old grill cloth. I've not done any of this so I have no idea how the cloth is fastened at the Casio factory so not sure what it would take to remove the old cloth completely. I've made several custom speaker enclosures years back and grill cloth was easy to obtain, not sure now haven't done any cabinet construction like that in awhile. Also not sure what type of adhesive would be best for this-would have to be something that will allow a tight fit on plastic to cloth and also allow enough tactile strength to apply on parts that will not show around the edges as you recover everything-a real upholstery project! Might try Weldwood contact cement or something similar. This is not easily removed from cloth if you make a mistake but can be removed from plastic pretty easily if you need to make adjustments as you go. It isn't transparent though so you will only be able to use it in places that will be covered by re-assembly. I haven't had good luck with hot glue on projects with plastic-doesn't adhere well enough. I think your choice of adhesive will be very important on this. I'm being silly now but don't get it in the keys unless you want to glue down a permanent C major chord for accompaniment purposes! Good luck and post back if you have questions let us know here how you do. I expect you may not be the only one who might want to attempt this.

SirLanceALot Posted March 5, 2016 Share Posted March 5, 2016 Rustar, did you get your speaker compartments removed? My 350 is still under warranty so I'm not taking it apart. However I've got the urge to upgrade the internal speakers. The sound of the 350 is incredible thru my Senheiser headphones and killer thru my homemade monitors. I attached a photo. Yeap, those are 60's D140F 15"s, their fs is an amazing 29hz, for musical inst spkrs, so they reproduce the low A with incredible power. 1 Quote Link to comment Share on other sites More sharing options...
Rustar Posted March 5, 2016 Author Share Posted March 5, 2016 No, I have not yet gotten up the nerve to cross that Rubicon, since the current fabric is acceptable condition.You have a really sweet setup there. Quote Link to comment Share on other sites More sharing options...
SirLanceALot Posted March 5, 2016 Share Posted March 5, 2016 Thanks Rustar. That's just something I threw together in the storage room above the garage to check the 350 out. I attached a picture of my set up an 85. I don't miss the days of hauling all that stuff around in a big truck. Looks great on stage, but I got the bad back to prove it too. 1 Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted March 6, 2016 Share Posted March 6, 2016 Those JBL 15's have an uncanny resemblance to Peavey 1504 Black Widows. Or is it the other way around? Interesting. Quote Link to comment Share on other sites More sharing options...
SirLanceALot Posted March 6, 2016 Share Posted March 6, 2016 BradMZ, The D140's have been around a LOT longer than the P's. However, ...., I dont want to take away from Peavy though. The Peavy black widow, smart design, allowed you to unscrew the basket with blown voice coil and screw a new one in. Quote Link to comment Share on other sites More sharing options...

rheowasserman Posted April 6, 2018 Share Posted April 6, 2018 You can replace it with acoustic transparent fabric . Which allows sound to pass through the functional core. You also need to know that these textiles meet the flame code and are stable and have been tested under the third party protocol for acoustic function.
