i got my heart set on the galactica... i know this is insane for a first time build. i just dont see myself wanting to do anyother speaker design. the blue prints for this design is kinda hard to comprehend. everything is metric and... just damn hard to understand. i get most of it. wish i could post a pdf file here to see if y'all could help. anybody here build one of these?

That's quite a monster. Looks like a bit of over-engineering to me. Two different woofers covering the same freuqency range, the larger in a sealed cabinet, the smaller is ported. Looking at the frequency response, I think one of those woofers would be enough. Looks like this speaker will have some heavy bass, 5dB above the rest of the response.

Good luck with that midrange cabinet. I don't know why someone would go through the trouble of that laminated construction if you won't see it in the end (like translam). It sure will be heavy and solid though!
 
Wow.... Is this a DIY Avalon?

This would be hard to build for a carpenter let alone a first timer, but sometimes you gotta do what you gotta do!!!!

If it were me I would get all the parts CNC cut from plans. You could spend 'ages' by hand using trial and error or spend ages plotting the individual parts for machine cutting and have a much better chance of fit and finish.

We are talking a week or three all day wood work here doing it by hand 🙂 with many tools involved in a 'decent' workshop.

I'd be having a huge party if I pulled this one off first time!!!

Best of luck and kick ***!

You said in the other thread you had good woodworking skills, so go for it. That's the hard part of this design as TG has done all the rest for you.

I have heard some of the PHL drivers in my friend Terry's very impressive system, detailed here - post 68 has the finished pics.

Welcome to the metric world in the 21st (and a bit) century!.

Here is a great little converter tool that I use all the time when I talk to Yanks and have to put everything back into antique measurements.

You can get the Ciare 15's from Assistance Audio and they are often listed in his ebay store.
You'll get a better response if you phone rather than email.
 
The Klipschorn is a great speaker cabinet, but it is a difficult one to build. It has many double angle (bevel) cuts and is not appropriate unless you have a fairly good skill set. Also, some of the plans available for the Klipschhorns are inaccurate.

Building a Klipsch La Scala is a less ambitious project, altough the bass will not go as deep. Another alternative is building a Klipsch Jubilee. The plans floating around are not fully accurate but they will work well enough. However, there are a series of decisions regarding the HF section.

If you are serious about a Klipsch build, you will get plenty of feedback over at the Klipsch forum.
 
If you like klipsch horns, you will like this corner speaker design, the Seven Pi.
But, you need the right corners for best sound quality.
I know these speakers can ROCK, and get loud. They sound good with solid-state or tube amplification.
If you are interested, you can reach Wayne Parham by email, or on his forum, he is very accessible.
He provides free plans for examination just by asking.

Pi Speakers

Good luck with your project.

after a little listening to the only pair of Galactica's in The Netherlands i decided to build them 2 little brothers😀

My topic of the build can be found here: link

i am sorry, but it is in Dutch 🙄


Any questions, feel free to ask, i'll try my best to answer them....and yes i use the metric system overhere, so sorry, no inches, feet, thumbs elbows and gallons...just plain meters and liters. 😉

you were quite right there, a short while ago, Tony Gee developed the Mezzo Galactica:
An externally hosted image should be here but it was not working when we last tested it.


He ditched the 12" and went for a different 15"Ciare but kept the midrange and tweeter.

Might be worth a read: Mezzo Galactica webpage

I second that. Maybe there are two... for if one explodes! The build is beautiful for a 3Way (,5). And maybe the woofer could go lower to 30Hz or so. Extension, extension, extension.

Because of his insistence on using passive xover between the drivers he can't use a dedicated sub driver to get lower in a reasonably small box because then the efficiency of the rest of the system would be dragged down. Active, a different LF driver could have been used with the 12 and up passive (if desired) and it in a sealed box as it doesn't need to go as low.

I have the detailed drawing for these, and would like to build something similar looking and in general design later, but I won't be using the same driver selection, just general layout and active instead of passive. Looking at the drivers I have here already to use, LF can either be a HE 18 EQ'd via LT to the response I want, or a sub 15 with no EQ.
 
Well...i dunno about our topicstarter sidewalksissy but i am well under way with the topcabinets for Tony Gee's Galactica's.

After a huge ******* mistake, which cost me al shedload of MDF and several days of routing, the topcabinets are almost getting their shape.

Unfortunately my topic is in Dutch but you get the general idea 😉

page 9 is almost full....tomorrow some more work and pictures and we'll reach the tenth page

cheers!
