Has anybody used this and is it any good? I understand that you hook it up behind the microphone attaching it to the mic stand. Is that right? Does it have the desired effect or is it just an overexpensive gadget?

[drummerdude666]

I've seen it at a trade show before and i had a play with it. Unfortunatly with all the noise there - you couldn't tell how it was affecting the sound. But it sits behind the mic attached to the mic stand as you thought.

What is the Reflexion Filter?
The Reflexion Filter is basically a portable device for recording live sources with reduced room ambience. It is an advanced composite wall which is positioned behind any microphone by means of a variable position stand clamp assembly which ships with the product. The main function is to help obtain a 'dry' vocal or instrument recording. This is especially useful in studios without proper acoustic treatment, but can also be used to help record takes in control rooms, where the performer also has to operate the recorder, or in rehearsal studios to reduce ambient noise.

The Technical Bit:
The Reflexion Filter has 6 main layers. Firstly, a strong layer of punched Aluminium which allows sound waves to pass through it, diffused, to a layer of absorptive wool. The waves then hit a layer of Aluminium foil which helps dissipate energy and break up the lower frequency wave-forms, and from here they hit an air space kept open by rods passing through the various layers. The air gap acts as an acoustic barrier. The sound waves then pass to a further layer of wool and then through an outer, punched, Aluminium wall which further serve to absorb then diffuse the remaining acoustic energy.
The main absorber has formed pieces of Aluminium Foam attached to it via the extended separation rods, which further serve to absorb and then diffuse sound waves as they pass to the main filter.
The stand assembly comprises a horizontal bar onto which both the Reflexion Filter, and any standard fitting shock mount can be fixed. Both the microphone (in its shock mount) and the Reflexion Filter can then be moved both vertically and horizontally along the bar to obtain the optimum working position.

How does it work?
The various layers both absorb and diffuse the sound waves hitting them, so progressively less of the original source acoustic energy passes through each layer. This reduces the amount of energy hitting un-treated walls and other surfaces so there is less of the original source reflected back as unwanted room ambience to the mic. The Reflexion Filter also helps prevent any reflected sound reaching the back and sides of the mic. Its shape and size have been carefully tested to maximize absorption while keeping 'coloration' down to only around 1dB, and leaving the microphone's polar pattern unaffected.

In summary:
All in all, it's a very clever and desirable piece of kit. It allows you to record vocals, guitars etc with a 'drier' sound without having to have an acoustically treated room. It's portable. It uses state of the art materials. It works… and it's a fraction of the price of acoustically treating your studio environment!

that was a neat description I 've got one on order & I'll probably have a double mattress at my back when I use the screen

on the other hand I might not (have a double mattress)

Ddude666 thank you very much for that

I can see no point using it, you'll need good room acoustic facilities and noise attenuators anyway.

the mattress or the reflexion filter

I was making one of these and signed up for a patent-pending...

the concept was for taking out the "room", especially the backside of the LDC's in crap drywall rooms.

Then I noticed there were others already out there.
Doesn't Auralex have a wedge or something too? Same concept.

This one looks nicer and they went much further with the 6 layers and panel approach.

as far as "working"... another tool in the studio?

My skeptisism is if the room is very small I don't see how its going to block much sound as its so far from the mic, has open top, open bottom?

[60's guy]

It might work in a pinch if your room environment isn't very good. It might also be useful for narration and voice-over work. Just a thought. Pretty stiff price though, for what it is.

I have used devices like this that were homemade and usually "temporary" in nature. It is really just a small proximity gobo placed on a stand. It's use would, in my opinion, be best used in a small, minimally treated room. This device, and others like it, will make more of a difference in your sound then you may think.

200 pounds are far more expensive than what I woiuld expect for this type of device.

[slidey]

is there such a thing as a search engine that will take the product (in this case the SE RF) & look for the cheapest deal...........

if £200 is considered steep I wonder what it can be got for it's advertised in sound on sound at £229

[COOLCAT]

here's another angle, $50 Auralex expanders

Has anyone here actually used those?
I was wondering how much they effect the sound.

[COOLCAT]

A DIY, mine was shaped like a amphitheatre, with foam inside the casing.I tried cardboard, plastic, box, rounded, square...all had pretty much the same effect. This is the only one I tried.

do they work? anything can change the sound of your mic.
same as a towel or your hands cupped around the mic, blankets, a corner of the room, foam, metal plates...etc.
I agree with what Chip Evans stated on this side of it... you'll hear it.

$200 seems kinda high imo, i'm with gilwe.

Imo, its kinda like a $200 multi-effect pedal patch that's called MARSHAL STACK. You have a $200 thing, instead of a Vocal booth or treated room.

now that I think of it, I finally searched for a different microphone that was uni-directional and required the sound to be close to get rid of my Drywall echo Crap-hole sound.
I never use my never patented DIY DEFLECTOR REFLECTOR MIC SHIELD ISOLATOR FOAM AMPHITHEATRE CARDBOARD PLASTIC SHIELD anymore.


Being open-design, I don't see how it prevents sound coming "into" the mic ?
The one I made was closer, had a top and bottom and took the room out more I would guess. It cost about $10 to make. More like the Auralex, but with the "amphitheatre" shaped housing.

damn..1000 orders already at NAMM $200 each...not bad at all.
Thats $200,000 approx!! It is very professional looking and appears well-built.
Much more materials & science and physics went into it, probably.

[EdJames]

Even worse than that, in the UK the SE Electronics RF Reflexion Filter is £200, thats pushing $400!!! Cheapest I found it was £196.97 which is $345.84 plus delivery costs. Essentially, if I'm to buy this I wanna know if people think it'll be worth the money!

[drummerdude666]

I have the code of a deal for it from Digital Village. I think it took the price down to £110. I'll see if i can find it..

I cant find the code, but it was a special promo price at Sounds Expo. It was a show deal, but i asked them if i could pay this price another time as i couldnt pay there and then - so they gave me a code to use. The only problem is finding it...

I have a big bag full of catalogues from that show, but i cant remember where i put it. I'll do my best though.

man you'd be the best dude on the planet

[slidey]

I've recieved it, tried it out with the trusty AKG solidtube & WOW

It does what it says on the tin.............price a bit steep at £180 but in the long run it would cost me more in mental health bills if I didn't have it

a great piece of kit

[drummerdude666]

Good stuff mate, any chance of some clips? with and then without the filter?

ahem when I get a PC that isn't steam driven LMAO (sorry dude it will get there honest I'm not a dinosaur )

[EdJames]

Did you ever find that code?
