70cm tall, 3 way, diy speakers based on 10"/4"/1" japanese ken brown drivers.

They remaind me of my first "serious" speakers,three way Technics models.

I still miss the wind those huge woofers could blow to my face

p.s There is some stange looking screen in the reflex pipe.I'd recommend to remove it when you are fitting the braces,you could also flare it or add there a flared piece(without changing the length too much).

Now i'm wondering building these speakers http://www.troelsgravesen.dk/3WClassic.htm
If anyone have build these give a comment.

I haven't build these speakers but I have used the 27TFFC and some other SEAS Prestige (basic) drivers. I'm very impressed with the quality of these drivers. Buildquality is very good and they sound realy sweet.
You'ld be realy happy with a well designed speaker using these drivers. And I think this design is a good example.

what is a flared piece or flaring the pipe?
the second expression seems kind of sexual, jeje.

that screen is a plastic grill, for protection purpose i think. it came with the pipe as it is a professional audio pipe, that strangely was just the length i needed it to be. i thought it wouldn't affect the performance as it is really thin, but i wouldn't mind removing it next time i open the box. thanks!

thanks to everyone for the opinions!

ok.

this is just an off topic, but i have to say, that 70s speakers are good. They may be far from flat, but they have a certain sound that sounds good with old recordings, trading SPL for extension, with a big smiley looking curve. My dad has some technics 3 ways, and i dont knwo how they get soo much bass from a pair of low excursion 10s! when he cranks it it rattles EVERYTHING in my room! granted theres not much below 60hz....

...in fact id really like to built a similar pair of speakers sometimes, cause when it comes to some old zepplin vynils, or young or anything else of that era, they were all mixed to sound good on the cumbersome 3 ways of the 70s.

congratulations! you got me thinking about a new project! just what i needed!

[facundonu]

well! i'm glad that happened!

i'm a huge 70's rock and roll bands fan, mainly prog rock such as pink floyd, king crimson, yes, invisible (an argentinian band from that decade)... hard rock as black sabbath, deep purple, led zeppelin, etc... and stoner rock (wich is kind of new but sounds old) such as kyuss, queens of the stone age, natas, colour haze, nebula, om, karma to burn...
i've spent my whole day (today is "flag's day" here and i didn't have to work or go to the university) listening to that kind of music, and also some jazz and classical, and i have to say i'm very pleased with the results.

YES! i love your taste in music! QOTSA is a fantastic band, liekwise with flyd and king crimson(ever heard the album "islands"?)
