Title: DIY floor standing U frame speakers.
Post by: Guy 13 on December 01, 2019, 10:13:00 PM
Hi all.
In about a month from now,
I will be posting picture of a open baffle that I will put together.
I have all the components,
just waiting for the Vietnamese cabinet maker to make them for me,
he's busy working on other stuff I gave him to do for me.
I am not too good at wood working. plus I have no room dust proof and very little tools.
I did the design (U frame configuration) as per a previos one I did myself that look like hell.
That's why this time, I use a professional in wood working.
I will put to use all the components that's been gathering dust for several years.
8'' Audio Nirvana extended range driver.
Two 12'' Eminence Acoustinator woofer.
Two GR Research SA-1 240 watts plate amplifier.
Soooo come back in a few weeks to follow the evolution a a pair of open baffle speaker.

Guy 13

Hopefully the new ones will be better looking than my previous desastrous attempt.
The center ones.

Hi Guy,
You have my admiration for even attempting woodworking. Other than all the time it takes and all the dust involved, I like it  :roll:
Last year, I did a quick refinish on a cabinet top and surprised myself on how good it turned out.....

Nick B,
A picture of that cabinet top would be nice if you could share with all of us.
Of course, that's optional.  :)

One of these days Iíll figure out an easy way to post pics from my iPad that doesnít involve having my photos hosted on another site. I basically used a belt sander and the only issue is that the top is slightly uneven. I bought the cabinet 15 years ago as unassembled and unfinished furniture.

Hi HAL.
The speakers on each side of the ugly ones are GR Research V1 not the Super-V.
The mid and high section including the x-over are seperate as per my idea and design
and I think it look nice.
The center ugly one are U frame configuration with two bottom 12'' Eminence Acoustinateur
driven by GR Research SA-1 (240Watts) plate amplifier
and top is a 8'' extended range Audio Nirvana (Common sense audio).
Built by myself with a Black & Decker jigsaw with double wall three quarter inch mdf.
Some equivalent high density foam (Equivalet to GR Research Norez).
Hope this is what you were looking for ? ? ?

Hi all.
Another DIY speaker project is the restauration of my (Now in heaven) sister in law's
vintage Pioneer (Big bookselve) speakers.
The planet Vietnam humidity and Karaoke abuse from my wife
made those ready for a good overall repair.
Some mdf parts were rotten and the driver's coils burnt.
Sooo.... My cabinet maker will redo the exterior with selfadhesive vinyl,
make a new back and front plate and other stuff as we go along in the repairs.
I love the grills, so I will keep them.
All the drivers (8'' woofers and 3.5'' tweeters will be replaced when back in
North Pole or Canada (Same for me).
Here are a few pictures before and the pictures '' After '' will be posted in a few weeks.

Post by: Guy 13 on December 03, 2019, 08:22:49 PM
Hi all.
All the floor standing speakers that I build or got built
are on rollers (Casters) that's because they are heavy
(And I am only 5'5'' - 132 Lbs) so when setting up for
evaluation I often move them around,
it's much easier on casters.
After final sut-up, I use my heavy duty (Made in Vietnam) spikes.

Hi all.
I won't start a new topic, I prefer to keep my speaker project under this topic.
Another project is the replacement of the vinyl on my Rythmik F12G servo
subwoofers (I have two units).
On the pictures you can see that they are beaten up,
look like a 40 tons truck went over it.  :lol:
More picture when the work is completed, but not by me,
by my local cabinet maker.
These days, he keep him busy.

Hi Nick.
A few years ago when I order the Rythmik F12G from Danny Ritchie at GR Research
it came with a different color - finidh,
I  got tired and I did myself the recovering of the enclosure with local cheap and thin
vinyl and see what it look like a few years later after light use.
Thia time, my cabinet maker will do it for me and it will be with better quality vinyl.
He did a few speakers in the past and I was satisfied and the big thing is :
Here everything Made on planet vietnam is extra super inexpensive.
I will also post pictures of a sub base that is a design of mine,
original and different, I think.
We will see....

Hi all.
Today I went with my wife to see my cabinet maker
and brought him my Pioneer vintage enclosure.
At the same time, I took back some items on which he did modifications.
As usual, great work, nothing to say other than : 
'' Cam on '' thanks you.
I took the oportunity while I was there in his new shop
(That's doesn't look new at all, look more like a mess.....)
to take picture of him and him and me.
The old man with gray hair, that's me....

Hi all.
Another DIY speaker project.
I had for several years a small mdf cabinet that was used previously for a
passive input control.
I also had two small (3'') drivers from my computer subwoofer system (Cambridge)
that were in small platic enclosure.
So, I decided to put to use those two small drivers in a better, well, a little better enclosure.
My cabinet maker did a nice job.
Look like a mini guitar amplifier.
The grill and the back are removable.
The grill, believe me or not, is a clipping from my niece dress... :lol:
I still have to hook-up the drivers to the binding post and then see,
well hear how that little thing sounds.
Here are a few pictures of our (My cabinet make and myself) creation.

Hi all.
Yesterday I completed the wiring of the drivers on my new spekers.
Hook it up to my Decware SE84C+ with my computer as a source with the Schiit Fulla 2 DAC.
The sound was.... Well a little deceiving, but normal with small 3'' drivers,
but still glad I did the built, even if it doesn't sound like a hi-fi speakers,
at least they look nice to my eyes.

Hi all.
At last, at long, long last I got my Pioneer Vintage enclosures updated.
The outside was cleaned, now look also new,
the back plate - cover was replaced with a new one and a 5 ways terminal were
installed.
The front plate - grill was repaired and replaced
and he even re-installed the Pioneer logo even if it doesn't look too good,
at least it's there.
I am trying to see how much foam I will need to damped the encloure.
All the above for 40 USD for both enclosures.
The same job done in USA or Canada would have cost minimum four times that orice.

Hi S Clark.
I think it would be very difficult to find original drivers,
so, I will try to buy something similar.
The woofer is an 8'' and the tweeter is a cone type 3.5 or 4''.
For the crossover I saw something very similar mounted on a PCB
with a choice of different crossover frequencies.
I don't want to empty dry my wallet, since those speakers will be used
only when I miss and think of my sister in law, the original owner
of those Pioneer vintage speakers.
By the way, my budget for the replacement drivers - crossover is
around 100 USD.
I already found on the Internet what I need at Addison Electronic in Montreal.
I will buy and install the drivers when I am back in my home country North Pole
or Montreal, it's the same during the winter.
More questions, I like questions...

There is little reason to just pick drivers and hope they go with a crossover and a box when there are so many plans for DIY or professionally designed kits available.  For a very few more dollars you can turn those boxes into something approaching decent speakers. Just do a search for 8" two way kits or plans. 
Title: Re: DIY floor standing U frame speakers.
Post by: Folsom on January 04, 2020, 10:27:19 AM
Ya, unless you can match the old drivers the crossover will be just a nutty mess with random drivers... pointless.

Hi S Clark,
I went on Parts Express and the same websites
and they have some interesting kits,
however, they are in USD and are in USA.
More difficult to find something in Canada.
I might try Solen in Montreal.
Anyway, I am not in a hurry, just looking at them is for me a feast
for the eyes and mind.

Well Folsom,
we don't have the same vision for that project of mine (Pioneer Vintage).
I bought several speaker kits (Four 04) from Danny Ritchie
and 90% of them were modified
to my liking (Sonically and visually) and I was never disapointed,
I never complain that the sound was not good.
Of course, I admit going by the book would improve the sound,
but that wasn't my goal and by how much ? ? ? ?
I still have all the kits that Danny sold me and I am happy with all of them,
some more than others of course.
Please keep in mind that I am not very demanding sound wise...

Hi all.
I have four (04) speaker projects.
One is on going, two more easy one  to be done,
I keep the last one because it's a bigger project.
U frame speaker built from scratch and the design
that come directly from my audio twisted mind.
The last one will generate lots of comments,
that I am sure....

Guy 13

Note :
Dont forget that I build, modify and design '' MY '' speakers
for me, only me, myself, Guy 13
if others don't like it, well too bad.
I have as much fun modifying and designing than building the speakers.
Sure don't want to be rude or agressive, but that my vision of my audio hobby
and it brings me lots, lots of fun.

This is not meant to be disrespectful or confrontational.   Of course we are all free to do what we please with our stuff, but this is an audiophile site, and the results of random drivers in random 70's mid fi boxes will not turn out well.  But if high quality isn't the goal, but simply a nostalgia piece, then why not.

Here is the "why not".  If viewed from an audiophile  standpoint, then Folsom's description of   " a nutty mess with random drivers... pointless"   is accurate. 
And like Guy says "if others don't like it, well too bad".  Obviously, he is welcome to spend his time and money as he pleases.  But Audio Nervosa is ... audiophile, so expect some criticism.

Hi S Clark.
Thanks for sharing with me and others your view on the meaning of '' Audiophiles ''.
The way I see it, I don't fit into that category.
Therefore I will seriously reconsider my posting of my other projects,
especially the last one  '' U Frame ''
since it will not be built by the book,
but more according to my previous experiences.
That's how I am and I am not ready to change...
I love what I do and the results have been alsways good to my eyes and ears.
I come back to my Pioneer vintage speakers,
after installing new drivers (Chosen to the best of my none audiophiles knowledge)
they might just sit on a shelf to be admired and it I listen to them,
it will be just for a short while...
I think I mentionned that in my original post.
If Audio Nervosa is only for audiophile members and projects
then I don't know what I am doing here ? ? ?
I am not angry, I only say what I think with the English words
and sentence structure that I know and that I am confortable with.
You are entitle to your views and opinions.
That being said, I will go back at my '' Smile with Guy 13 ''
where I don't need to be a Certified audiophile ''  :lol:

Thanks all for your comments and suggestions.
This part of the topic (Pioneer Vintage) is now closed.

Title: DIY floor standing U frame speakers.
Post by: Guy 13 on January 07, 2020, 06:04:50 PM
Hi all.
Several years ago I bought from Danny Ritchie (GR Research) a pair of M3 drivers kit.
Didn't see it on his website, but it's similar to the AV-3 ? ? ?
I put together the crossover on a board (Masonite wood)
and did the soldering with my trusty - rugged Weller 100-140 watts soldering gun.
The cabinet was done by my Vietnamese cabinet maker,
of course I didn't use Danny's cabinet design, but I kept the internal volume the same.
I did some bracing and used the medium density eggsell foam with some white stuffing.
The cabinet is made of 3-4'' mdf.
I did the vinyl coating myself and it shows.
Poor job, that's why after several years looking at it everyday,
I decided to give them to my cabinet maker so he can re do it in a professional matter.
I will also get a sand filled stand with base so that the drivers are at ears level
instead of putting them on a step stool.
I use the speakers for my home theater with a 20 years old Pioneer receiver
and I am very satidfied with the sound, the bass goes deep enough
for me and the mids and high are good, cannot complain.
My wife used the speakers with her 300 watts Karaoke amplifier and it survive,
surprising, since she went thru two pairs of speakers before that.
More pictures to come after the Vietnamese Lunar New Year when everything is back to normal,
if there is such a thing on planet Vietnam.  :lol:

Hi all.
Another project, this one in progress.
The coaxial drivers (8'' PAudio - Thailand), the assembled crossover (GR Research),
the 12'' woofers (Eminence Acoustinator) and the plate amplifier (GR Research SA-1 (240 watts)
all purchased as kit from Danny Ritchie - GR Research.
The Ferrari red enclosure made by my Vietnamese cabinet maker as per
Danny's original V1.
The foam is very high density foam that I found locally for  pennies...
I also have heavy duty spikes, but for now, it's caster for ease of moving around.
All built with three quarter inche mdf.
I did lots of experimentation with different mids and high drivers,
that's the reason why the top of the enclosure is a mess....
Will be fixed as well as the cabinet itself.
The cabinet maker is working on a sub enclosure for the Pi Audio coaxial driver.
More pictures to come when modification are completed, hopefully at the latest this week.
The bottom section, the woofers (Two X 12'' reverse) is one of the best bass performances
of all my speakers.
I even prefer them to the GR Reaserch servo drivers of the V1,
playing at low volume (Of course).

So, you built Danny's N3S kit but completely changed the box and driver alignment. Then you built his V2 speaker according to V1 plans, even though all the drivers are different.    :roll:   
Your money, your time, your speakers.  But you put this stuff online, so deal with the critizism.

Yep ! I did all those crazy things and guess what ?
I live the sound of each of them and I had fun doing all those crazy things.
My money spent was a lot less than buying speakers from well know brands...
I don't deal with critizism, I ignore them...  :lol:

Good for you.  Glad you like what you've done.  I don't expect anything different.  But I do hope to show any newbies that might look in here this is not a plan to follow.  And these are not the products of one of the best speaker designers currently out there, but some bastardization of his work.   If all you do is throw drivers in some boxes, you get a ....  mess.

Hi all.
My Audio 13 (GR Research M3) speakers completely modified that I use with my Home Theater system
are getting an overall revamp.
I strip the vinyl that was severely damaged and I will get either new vinyl or even better,
get them painted with automobile paint by the same guy that did my other speakers (Ferrari red)
I will also recess to the inside the tweeter by 1cm so it is more aligned with the woofer. (M130 GR Research)
My wife want red with the (New) base black.
Hopefully it will look hawsome in our living room in Canada.

FWIW (For what it's worth) my favorite colors are : Red, black and white.
The color I really don't like is :
Green, except for tree leaves and grass.

  I prefer black color. Why ? They disappear more in low light.
