CES: Where have all the Argent Room Lenses gone???

I built myself a set of 4 of these and I can assure you to do this right, it will cost a lot more than $20. The hole saw necessary to do the plunge cuts will cost you almost that alone. Then add the cost of paint, I used walnut on the tops and 2" pine on the bottoms, then added casters/wheels and several coats of clearcoat and sanding in between. They came out looking better than the originals IMO. As for what they do, there is no question that they make a very noticeable difference in smaller rooms.

I have a set, and they have make a tremendous contribution. The benefit to the soundstage has been identified by anyone that ever heard my seytem. I have a full wood and metal shop and still opted to buy them used for 500 or 600. They are not as simple as they look.

Thanks guys (and gals?)... interesting all this... I am or was tempted by the Room Lenses because I've moved house, and once again find myself with an acustically not so great room... I was spoiled by my last LR, which was fully treated with anechoic faom panels wherever necessary (including the cieling and some windows, even parts of the floor)... after much hard work I ended up with really excellent results, and probably the most significant improvement I ever experienced in the system. I'm trying to avoid going to such an extent this time as the place is not mine, but will probably have to get creative and do some free-standing panels (I was nuts enough to bring all the foam to France). I will also need to block out the noise of passing cars and revved to death 2-stroke scooters (ahh Europe!... fortunately this is compensated by the live music scene, which is the real deal). Anyway, thanks again... more opinions/info always welcome.
