Sixes Posted April 15, 2021 Share Posted April 15, 2021 (edited) Having gotten “into” Klipsch speakers recently (pair of RP-600M and KG 3.2) I was looking to get a pair of Chorus speakers. A Craigslist seller and an hour drive and I had a pair of consecutively numbered Chorus. All original parts. The upper cabinets were in decent shape but the risers were completely trashed. Veneer lifting, cracked, corner pieces missing. Electronically, there was no sound from the tweeter on one side and crappy sound out of the other. I decided that a full crossover rebuild was in order. Having previously bought and installed a Crites crossover in my KG 3.2 I opted for the full Chorus rebuild from Crites. I did an install video here: I also bought the Crites Titanium diaphragm replacements. I also did a video of replacing those as well: Regarding the risers, I took them off and stripped off the old veneer. It was tedious, but well worth the effort. I bought some oak veneer on Amazon and with some spray adhesive it was surprisingly easy. I also bought some Magic Slides to raise the risers off the carpet a little higher. Should avoid damaging the corner veneer again. I also put 1” wood screws in each plastic corner brace of the risers. Several fell off quite easily which seems common from what I have seen, so I also used wood glue on each. Cosmetically and sonically, they are now 110%. I added some sound absorbing foam on the top of the risers, securing with spray adhesive. It cost me a total of $1000 for the speakers, parts, and electronics from Critesspeakers.com. I recommend their products 1000%. Edited April 15, 2021 by Sixes 4 1 Quote Link to comment Share on other sites More sharing options...
Chorus1 Fan Posted April 15, 2021 Share Posted April 15, 2021 Looks great, did you consider doing the "port mod" ? Quote Link to comment Share on other sites More sharing options...

I bought and installed the 4” port tubes from Parts Express. Didn’t notice a difference but I didn’t go the full 7” nor did I flare the inside port opening....yet!!!! I saw all your mods and I guess you were my catalyst for what I did. So thanks!!, 1 1 Quote Link to comment Share on other sites More sharing options...

So thanks!!, Cool, & thanks! I would say don't expect a huge increase in bass, just a better, solid low end (depending on the recording) In my case, I used a cd bass freq "test tone" cd & did before/after testing. Before, anything below the 45hz note was barely audible. After, the dropoff moved down to 39hz - 38hz range. 1 Quote Link to comment Share on other sites More sharing options...

I’m going to play around some more. Quote Link to comment Share on other sites More sharing options...
Sixes Posted April 16, 2021 Author Share Posted April 16, 2021 (edited) I’m driving the Chorus speakers with a Kinter Tripath 2020+ amp pictured here. Works great till I get something else. Edited April 16, 2021 by Sixes Quote Link to comment Share on other sites More sharing options...

Works great till I get something else. I have one of those myself, but you'll REALLY be impressed (& get better bass) when you get a bigger amp. I have a Luxman R-115 that is rated @ 70w , but magazine tests "back in the day" said it was more like 85w continuous. At about 10 o'clock on the volume, things start falling off shelves 😃 Quote Link to comment Share on other sites More sharing options...

I am waiting for a Super Zen Triode amp from Decware that I should have in June/July. I also have a cheap Dayton Audio DTA-100a arriving soon. That’s a Tripath with a little more kick!

Chorus1 Fan Posted April 16, 2021 Share Posted April 16, 2021 Cool! If you lengthen the ports to 7-7.5" & connect that Onkyo, I think you'll find even more clean tight bass 😎 Quote Link to comment Share on other sites More sharing options...

Yankee Frank Posted May 25, 2021 Share Posted May 25, 2021 I am going to do this port mod. Are you including the thickness of the 1" motorboard in the 7 to 7.5" length? Thanks for your help! Quote Link to comment Share on other sites More sharing options...

Go to page 2 for detailed port info, but the port gets mounted flush with the front of the motorboard. (So it's included) 1 Quote Link to comment Share on other sites More sharing options...
