Hi community, I want to restore my dustcaps for my K3.2, but there are only black ones available. So I need to repaint them into the dark gray color. Any idea what color I exactly need?  

Hello everyone, this is my first post on this forum and I would like to ask a question. I have two speakers, one from a Klipsch r-115sw sub and the other SPL 150 and I would like to build custom boxes for them. Has anyone measured the Thiele Small parameters of these speakers? I would like to connect them to an external amplifier and the measurements show that they are 4 ohms so I could connect 2x4 ohms or 1x8 ohms.

I use a polyswitch with 100ohm resistor in parallel.   Do a search for polyswitch in the forum, lots of references. Newer Klipsch crossovers use them.

Probably a failing capacitor in the amp.

@Zen Traveler The audio store is in Almere and is called Atube high fidelity. 

You may want to check some other styles for that use...lots of great folks here with good advice, but you may find more content specific to headphones here:   Head-Fi.org    

Dear Maz:      Thanks very much for your reply and advice.  I understand your reasoning.  I am here to report that I went ahead and built your 2.5 crossovers!  I bought parts from Dayton Audio (not far from where I live) and tried to balance cost with quality.  I did not have any stock of parts in hand so I needed to buy everything.  The build went pretty well; I screwed the plywood supports to the back wall of the speaker, above where the previous crossover sat.  I've included a photo here of the pairs of crossovers (each in two pieces) that I built with the comparatively tiny original crossover in the lower center.  I replaced the old 1990s foam (also shown in a photo) with new rockwool but only lined the top half as it had been previously.  I also replaced the original tweeter diaphragms with the Crites titaniums.  Thus far, I have not added additional bracing, since everything seems solid.         The sound is great.  The only difference from your latest 2.5 version was I left out R2 for now -- I was afraid that it might tone down the treble too much, and I am happy with the results.  The treble is tamed, the midrange is up and everything seems well balanced.  I am dealing with some bass boominess, but that is more about the speakers' location in the room  than about their build and I can just eq that in my DAC to help.       Thanks again for your work and sharing this so that we can benefit from it!   John  

I had an 83 firebird that I put a set of paradigm speakers I’d the very back where the storage area was. Sounded fantastic.
