Guy, I like the top one best, it will likely help maintain a little more bass output from the driver as well.  I would recommend adding back your rear wings to help with the bass as well.  Very nice looking, good job.

Best,
Ed

Hi Ed.
I just want to make sure I understand what you are saying,
because my main language is Moliere and not Shakespeare.
You mean the red cloth is making the front baffle wider
and therefore increasing the bass.
It make sense, however, this design of mine was to follow
what Danny Ritchie told me several times about many,
if not all of my built,
the baffle should be as small as possible to avoid diffraction
and/or reflection.
Therefore the cloth is more or less transparent to let the sound wave go true.
For now, I am not looking for more bass from my Omega,
because, believe me, I've got more than I want from my bottom
H type OB dipole sub-woofer.
Later, much later, when I have put aside enough money,
I will get a pair of bass reflex enclosures as per Louis recommendation
and maybe, eliminate the BIG sub-woofer.
I know that having some wings as per my previous set-up does help the bass from that small driver, but for now, that's not what I am looking for.
Thanks for the recommendation.
Now, how about the foam stuff,
which one is better or is it better without it?
Of course, I can experiment with and without foam,
but first I want to see what AC members have to say about it.
DIY = experimenting, but not blind less experimenting,
because you can turn in circles for a very long time
and sometimes never reach your goal.
Waiting for more advice...

Guy 13

Note:
I just found a way of reinforcing the front baffle.
I won't have to buy some metal brackets as I thought.
I have some leftover wood
and I made nice looking brackets.
Tomorrow, I will paint them with leftover black spray paint can
and post pictures when installed.

Hi all.
As mentioned in my last post,
I’ve installed a wood support bracket for my Omega 7F front baffle.
This gives a little more rigidity to my set up.
Does it improve the sound? I think not !
Anyway, if the sound had improved with that up-grade,
the music would be the same as if I had the orchestra in my listening room.
That’s how good the Omega 7F are.
Thanks to Louis and sorry if I was a pain in the neck with all my questions.
At very first, I wanted to buy both Omega 5F and 7F,
I am still wondering if the 5F is better than the 7F
other than the bass extension in my OB dipole set up?
I am still waiting for suggestions about the foam padding for the back of my Omega.
Well, I will experiment myself, 
without any help from the Audio Circle members
(No I am not complaining or critisizing, only telling the facts...)
and after that, I will share my findings with you.
(See, I am not a bad guy, I still want to share with you.)
That’s not what I really wanted, but in life,
you cannot always have everything you want.
Humm mmm…

Lots of photos in this thread, thanks Guy for your time.
Nice cable support, its wood or foam??

Hi FULLRANGEMAN.
They are made of MDF
and painted with a primer/base paint,
so that later I can paint them a color that will match my decor.

Yes, thanks for all the great pics and I like the way you did the wood work, they look really good!

Hi Beowulf.
Thanks.
My contraption would look 1,000% better if Ruben from Outofthewoods
would have done them for me.
But like I say:
No money = No candy...
I sat to myself: SOUND is better than LOOK !

Hi all.
I did some listening with two different types of foam
and I could not hear any difference.
It does not mean there are differences, but I can't hear them.
I will leave the yellow egg shell foam for a week,
then swith to the black flat high density foam
and see/hear if there is any differences.
Thanks for your help.

Guy 13
Anyway, regardless which type of foam,
I still enjoy the sound of the Omega 7F.

Any porcelain device will do electric insulation to fit as cable elevator as coffe mugs etc
But not with wife acceptance though.

Hi FULLRANGEMAN
I have no problem with WAF,
she rarely come in my listening room.
If I want her to see my latest built or acquisition,
I have to drag her by the hair like the cave man
in the dinosor hera.
By the way, those MDF cable supports made me poorer
by 0,50 USD each.

You lucky, its very cheap.

[JLM]

I used scraps of 2x4's (free), but heard no difference.   

Now my speaker cables are short enough to not touch the floor anyway.  I removed the binding posts that allowed the cables to run directly from my mono blocks to my extended range drivers (8 fewer contact points in total), and used rope caulk to seal the cabinet penetration (my cabinets are transmission lines so have a large opening already anyway and act as a tension relief point).

Hi JLM.
For me,
no difference in sound with or without the speaker cables raisers.
I read somewhere that it can make a difference if you have wood floor.
True or not ?
I don't care.
I have 12" reinforced concrete covered with ceramic tiles.
If I wanted to, I could run the wires directly from the drivers to the 5 ways binding post of the Decware amplifier, but it would look.... Bizarre !
Your approach to minimalist cable connection is very good.
Well, I don't have to mention that, you know that already.
I can't believe, well, I do believe that some audio nuts will pay up to
50 USD each  for some electrical high voltage insulator.
Well, if they like it and they believe it improve the sound.
Good for them.

Hi all.
I want to share with you my fantastic experience
with my Omega 7F that are now celebrating their 50+ hours of live
under my roof and thank Louis for giving me the opportunity to buy his drivers and enjoy music more than I ever did before with any of the several sound systems I had.
First thing, after 50 hours of enjoyment,
they don’t sound better than when I listen to them during the first hour of their life.
They still sound very good, even better than before.
Yesterday I was listening to my Omega 7F with this newly acquired CD of music and was surprised how good my Omega 7F reproduced the tonality of the instruments.
I am at lost when it comes to use correctly all those words that the majority of the music listeners use to describe the sound that comes out of their sound system.
They usually go by frequencies slice, the highs, the mids and the bass.
The Omega 7F are full range or extended range as some prefer to call them.
My 66 years old ears are certainly not what they use to be, but even if they are limited between 12KHz to 14KHz the highs are not shouty, that’s the first quality of the Omega 7F details with sweetness, that the best way for me to describe how they sound.
Any musical instrument like cymbals, tubular bells, high pitch guitar are very natural, this is due to the fact that nothing is in the way of the signal path.
Amplifier directly to drivers.
The mids like voices, any instruments and even harmonics of the bass drum are very natural, you hear details that make you think that they are in the room with you or if I put it another way, the texture of the sound makes them more natural, you know what instrument is playing.
You just don’t listen to music, you enjoy every note the instrument can play.
As for the bass, they are playing full range, nothing in the way, no capacitor, no inductor and no resistor. Yes, like many extended range driver they have a bump in the 2 to 5KHz region, but it’s not the Mount Everest.
I can live with that very easily and I will never put anything that will change the sound or damage the sound.
The bass is supplemented with an Open Baffle Dipole set of two 12” Eminence Acoustinator subwoofer driven by a 250 watts ss plate amplifier and even if on paper the characteristics of the Acoustinator is very far from being ideal, they always surprise me with their authority. I describe their sound as deep with details, as much as the Omega surprises me with their natural sound, I can say the same with the sub-woofers and you know what?
This system did not cost me a fortune.
The best word I have chosen to describe the sound of the speakers is:
Lively.
I wish all of you Audio Circle members that love simple set up
would be able to come to Vietnam to listen to my set up, I am sure you would like it.
To conclude, I am happy with my Omega 7F, thanks to Louis driver that have change my audiophile live.
(To bad Louis does not offer them any more.)
Find below a few pictures for some of the rare AC members that never saw it.
Like my avatar says:
Audio should be simple
And in my case, it is simple.

Guy 13

If my bank account would be filled to the rim with those nice Benjamin Frankin I might try the Bottlehead Stereomour but not sure if the Stereomour at 850 USD would be any better than my Decware SE84C+ SET already paid for but with a border line 2 wpc power output ? ? ?
I am sure there are many systems that sounds better than mine, but how much more would I have to pay to get a little better.
Every time you double your investment, you don't double the quality of the sound.












This is the CD I've used many time to ear how good my Omega 7F
are.



 
 

[Guy 13]

Hi all.
Some of you have read my topic on my new Bottlehead Crack
with Sennheiser HD-650.
Now, even if that combo sounds very good,
I must say that after a more or less side by side comparaison between them and Louis Omega 7F with sub-woofers it sounds way better than my combo mentionned above.
More bass, deeper bass, more realistic bass and the same for the mids and high's.
In all areas, Louis drivers beat hands down the headphones.
I am sure I will use my Decware - Omega 7F combo more often then my combo Crack - HD650.
The Omega 7F sounds better and playing a a discotec level is no problem with my listening room with it's 12" armored concrete bank safe style.
Just wanted to mentionned and there is nothing negative about both systems.

Guy 13

Of course all of you know already that with headphones
the soundstage is zero.
With my Omega 7F set up, I do have a sound stage,
but I am still looking to make it deeper and wider.
Right now the sound is about 12" wider outside my l + R speakers
and the depth is no more than 12" behing my spekers.
I have not found yet a solution to increase the sound stage.
I would like to have a deeper sound stage that would complement the very natural and detailled sound of my Omega 7F.
Any suggestions?

Guy 13
 
 

[FullRangeMan]

For a deeper soundstage you must remove all the forniture behind the GR speakers.

Hi FULLRANGEMAN.
Have a look at the pictures on Reply # 32
and you will see that there are no furniture behind my speakers.

Guy 13

[FullRangeMan]

Iam referring to this black wide forniture holding various equips.
Also would be good remove the red table in front of the speakers.

Hi FULLRANGEMAN.
Removing the black IKEA audio furniture would mean to have longer speaker wires,
something I would like to avoid and as for the red table is concerned,
that's a recent addition, the problem was there even before I've put that small IKEA red table between the speakers.
If I had two strong arm to help me to move the audio furniture I would do it to see if that's the problem, but without help, it's too much work to move it.
Any other ideas?

Guy 13

[FullRangeMan]

OK other idea would be push this Ikea black fortinure very close to the wall (the gray curtain wall) if the speakers cables lenght allow.

Hi FULLRANGEMAN.
Do you think that pushing the IKEA black audio furniture by 37cm against the back wall will make an improvement big enough ?
Hummm ? ? ?
