  • Rebuilding Klipsch KG 5.5

    I have inherited a nice pair of Klipsch KG 5.5's. My Father bought these for my older brother when he was a teenager (in 1998 slightly used) and I was just a little kid in 4th grade or so. I remember loving these speakers when I was young and never grew out of big speakers with 10" woofers. This was my first experience with Klipsch and have been a fan since. When I was old enough and made enough money I put my Home Theater together with Klipsch RF-82 main and RB-81 center. These KG 5.5's will be my surrounds.

    I was putting together all the parts for my KL-650 clones, but decided to go with these KG 5.5's. I like the sound and aesthetics of a floorstanding speaker and placement is easy for me because I don't have to worry about stands or wall mounts. Plus these were my brother's so they are sentimental.

    My brother passed away about 5 years ago now and these were collecting dust at my Mom's house. No one was using them or claiming them (I have a lot of siblings) so I asked my Mom if it was okay to take them. I couldn't ship them as-is, and I wanted to build new cabinets anyway. So I disassembled them and boxed up all of the components to ship them to myself in Alaska.

    Since then, I have ordered Bob Crites crossovers for them, and Titanium diaphragms for the tweeters. I saw several areas where these speakers could be improved. I have also bought precision port flared ports and sonic barrier foam. The original cabinets were not braced and lacked dampening. I also bought some feet and I have the 3/4" MDF already. I don't plan on running grills.

    I will take pictures of the process and am open to tips and suggestions. These are going to be built well and used as surrounds for my 5.1 (actually 5.2 since I'll be running dual subs) for a long time. That's the plan at least. I have not decided on the finish yet for the cabinets. They'll be black of some sort. These will finally be my first DIY project and I think it's a great start. I have the plans for my cabinets and all the components are there and the crossovers are already built. I felt like it was a good idea to do something like this rather than 100% DIY for the first time. I was nervous about building other speakers, but I already know these sound great and I like the sound of them. I hooked them up to a receiver and placed them as well as I could. I auditioned them using a handful of different songs I like to listen to. I was pleased with their sound.

    I think they will blend well. All 5 speakers will have Ti Tractrix horns. All 5 are ported, 2 way speakers. And the crossover frequencies are pretty close. I am excited to say the least.

      just received my new crossovers and titanium diaphragms. Everything looks great! I am also gathering supplies to start the cabinet build.

        alright so everything has arrived. I have to go buy my wood now. I'll be using birch plywood due to availability. I replaced the diaphragms in the tweeters with the Ti ones. Pretty easy.

        So I have a question though. The old speakers used a plain straight port. I just have to add one inch to the overall length using the flared precision port correct?

          You can estimate the tuning frequency or measure it and replicate that with a flared port.

              alright so I haven't been updating this. I have pics to post. They are about 95% complete and sound great!! I was listening to an instrumental version of Fortunate Son and noticed one woofer was buzzing/sounded slightly distorted at even the lowest volume level.

              What is this caused by? I can't see any visible damage. Is it repairable? This seems like a common thing to go out on woofers I just can't recall what it is exactly that causes this.

              EDIT: Found two of the correct woofers for sale on ebay. Went ahead and bought them.
