I found a pair of these at a local audio shop. I really dig the looks, esp the slanted midrange/tweeter cab.
Does anyone have the plans to share? or any thoughts on the design?
From the appearance,
the vr-4sr looks like it carries the vifa xt25 as the tweeter,
some high-efficiency midrange that seems to be audax-type
and of course the seas L woofers
I already have a pair of xt19 in possession
midrange, i'm willing to experiment (budget minded though)
woofers, I've seen test that the rs225 actually have better distortion figures in the bass/midbass region than the excels, so I'll go with the dayton.
comments? thoughts?
any ideas on the rear firing ambience tweeter?
btw, I'll be running active, so there's some tuning flexibility

reading more descriptions from website, the vr-4sr sounds like a real challenge to clone
triple chambered, I can't get away with just a simple ported design now can i?

looks easy as pie to clone
TL's aren't hard to do... you don't have to make it EXACTLY the way they did... just do the same things
have you heard these BTW???

personally, i find that the baffles will require some serious woodworking on my part 
, so that's the 1st hard part
second, it would be easier if there's a clone documented somewhere, i'd like to know the exact cab's sizes and cutouts.
I also have no experience in any triple chambered enclosure, so I'm sure there's more researching for me to do. The dayton rs225 won't have the same cab's space requirements and tuning should be different as well.
I was at the auditioning room and was actually more intruiged with the newer Focal (yes, i said Focal) Profile.
I had the pleasure to listen to the new focal tweeters and totally forgot about the vr-4sr. Yes, they are quite amazing.

Well I based one of my projects on these:
Just with better mid and treble drivers. They were also sealed on the bass but later ported no TL thought.
I scraped the design and decided to do something unique rather than try to mash together bits from a proven high end speaker.
I can tell you for certain the drivers though:
Vifa XT25 treble
Audax PR170 mid
2 x Seas L22-RNX4/P bass
The XO points are also documented on the VR website so you'd have some good starting points if you wanted to do a proper clone.
Also the sizes of the individual cabinets ie. sat and bass are documented on the VR website. I followed these but chopped my bass cabinet down because I was going sealed rather than TL, hence its shorter than the actual VR4-SR.
The real construction problems are the sat, the sides are sloped, the baffle has angular sections, there's angles toe rear also. Its completely do-able as I've shown but there's more time involved and you need to draw up some CAD models to get the angles and sizes accurate.
I still have my dimension in a CorelDraw 12 file somewhere and I've got a load of pics that I took whilst building.

ShinOBIWAN, how long did it take you to build these? and what kind of price range were you in (CAD) ? They look wonderful, but how do they sound?
Shinobiwan,
great job on the cabs, they look wonderful,
how did you go about with the sat. cab?
I surely need all the tips i can get.
Do you still have the speakers in your possession?

The cabinets were abandoned and the bass drivers changed. New versions still ongoing. I'd say around 5-6 months to design, build and finish the ones in the pictures.
Materials wise they come to a total of around £2000UK. That doesn't include the active crossover though.

Its a pearlescent finish.
You can't really see it in that photo but it does change colours depending on light and angle, this photo shows it better:

Still have the cabinets(unused but can't bring myself to throw them away) but the Seas bass drivers were sold because I didn't like the sound. The midrange and tweeter are now being used in the updated model.
Pictures can speak a thousand words so I'll just post a couple of shots I took.

If you need the pictures, you should save them to your hard disk since I tend to delete them from my hosting service quite regularly to make room for others 🙂
wow, is that 4-5 layers of 1" thick mdf on the baffle? 😱
What type of tool did you use to cut the angle cuts?
I have a miter 12" (non slider), but I don't think the cabs will fit under the saw for the cut.
Gosh, wished I lived in the UK so i can just buy off ur cabs 🙁

Its 4 x 18mm layers of MDF. Makes it 3" thick. For the others I went crazy and did 5 x 18mm + 9mm making a 4" baffle. Definitely minimal resonances here 🙂
For the cutting I used this:
Bosch 12" double bevel sliding compound mitre saw. Its can cut around 35cm on the sliding action and it goes through 3 or 4" of MDF like butter. Its perfect for those type of cuts on the baffle or anything that requires a fair bit of accuracy.
I wished you lived in the UK too, I tried giving them away when I was selling the Seas drivers on here but nobody was bothered. Told myself I was going to skip them but they're still here 😀 I'm too weak to throw them away, hell I've still got a half dozen of unfinished cabinets in the garage that will never get finished.

Nice saw, I'm a Bosch fan myself.
Saved the pics and I'll see how my saw works out.
Do you still have the cad drawings?
Those cabs deserve a good home.

Is it Standox Montacarlo Magic? It looks just like my car, very nice colour.

Its Rage Extreme Illusion:

I agree with you about the colour, its nice but looks a little tacky an a pair of loudspeakers destined for the fronth room so I won't be using it again. Very flashy though.
ShinOBIWAN said:
Awsome work and color do you still have the drawings?
I would to use the same mid but was told that the xt18 from vifa was great to did you encounter some listening?
and the atc is it REALLY that good?do you feel any coloration of the sound since its a dome in a semi hornloaded?
very nice job!!

hello, can you share this file corela example on rapidshare
I thought about trying to clone these speakers a while back due the good bass in a small footprint cabinet that they are suppose to have. I pretty much determined after a bunch of research that the bass drivers are in a mass loaded TL. The three chambers are just three sections of the TL that are tuned with different stuffing and damping materials.
I ended up not gong that direction for various reasons.
