    Re: Flex Your PCD Mettle:

    The WG on the Arcus (white stand mount above) is simply the stock WG painted white.

    Those are massive speakers you have there. My friend here in town is upgrading his HT, and I know he'd love to see your set up. His will be in-wall, but I think he's leaning toward a 15" woofer and CSS Planar 1, which we now have on order. I can' t wait to begin testing that new CSS Planar 1. The Planar 2 looked incredible from the data Dave Thomas took a while back, and I understand the Planar 1 is designed for 500Hz operation.
    They are massive, no doubt. 208 liters is too large for most livingrooms, and that is why I went for the Econowave`s there. Not shure, but I might go for Econo as surrounds in my HT. The TPL-150H is a bit to expensive for all channels. I am currently building a center with the TPL-150H and one 15P80Nd.

    The Planar 1 (and 2) was new to me. Interesting.

    3.0 cu. ft. gives you a lot of options. The DC300 has been a popular choice since the beginnings of the Econowave project and provides good bang for the buck.

    If you're interested in spending a little more and want a sealed enclsoure, check out the Peerless SLS 830669:

    Or if you want a ported box, you might take a look at Dayton Designer Series DS315-8, which bwaslo has recently posted encouraging results with:

    Another option that wouldn't involve cutting the cabinets would be to have the original woofers serviced at the PE Speaker Repair Center:

    The directivity is going to be directly tied to the diaphragm shape. With planars like this AMT, or long ribbons, the vertical directivity is going to be narrower, and the horizontal, wide. This is the type of guide you really need to use with such diaphragm shapes.

    I'd make a rectangular form, and press your guide using a rectangular plunge instead of the circular dowel you use for domes.

    I contemplated using a quarter of an 8" piece of PVC tube, to make the horizontal sides of a guide for large planar devices. The Beyma is pretty much a straight sided guide, with flared ends to meet flush with the baffle. But I wonder how a circular profile might aid/detract from the overall response.

    Here's the drawing of the guide Dave.

    You can see that the angle on the top and bottom is pretty sharp, but it is symmetrical.

Interestingly I have been working with a planner in my guides and haven't liked the results so far. The less angle on the throat seem to give better results but wont give much boost unless it is quit large. I was thinking on the lines of what your guides appear to be. Start with a low angle going sharper as it reaches the baffle edge. I was also thinking about doing it as a round guide and cutting the top and bottom off on an angle then gluing on a flat piece. What would you say the top and bottom angles are, around 60 degrees?

    Teddy, I want to see pics of your Beyma setup.

    We just built an awesome stand mount monitor using the Beyma and an Acoustic Elegance TD10M. The sound is amazing.

    Re: Flex Your PCD Mettle:

    If you want to stay inexpensive, I really like the DC300. Check my sig for my Econowave. A quick DC300 model in 3 ft3 ported gives 105 dB F3/F10 30.5/22.1. Fb ~24.3 (3x8).

    Sealed in 3ft3, your F3/F10 44.6/24.5 103.6dB

    Moving up a bit in price and output, the Dayton PA310 or Eminence Beta 12A-II will also work. Of these 2, the BEta 12A will play a fair bit lower than the PA310.

    Re: Flex Your PCD Mettle:

    Wow, those look great! Is the WG from Autotech...?

    Posting a couple of pictures of the "Miles" here. Havent got any finish on them because they are going behind the screen when my room is finished. My room is only 12sqm atm, but is going to be about 27sqm when I get around to replacing the load-bearing walls, with beems. (unshure of the correct english word here..) The odd shaped subwoofer is made that way because I wantet to stack two in each corner and have one woofer next to floor and one next to ceilling, in an attempt to get more even bass-respons. Small footprint was also a goal. Havnen`t got pictures of the setup right now. These pictures was taken before everything was finished.

    The designer of the inConcert Miles (Stig Erik Tangen) doesn`t do commersial speakers anymore, and have shared his "recipe" with us. The picture is gone from the website, but the rest is there. The inConcert Duke is also interesting. Featuring TPL-150 and two 12P1000Nd.

    Love the sound. I must say I was a bit sceptical about how good a cheap CD like the Selenium could sound, but I shouldn`t have been. I will however try the B&C DE250 at one point in the future.

    Anyone seen or heard of a 2 1/2-way econo, or a 2-way with two 12" in a MTM config...?

    I have gone the DIY-route on all my speakers the last 3-4 years. Commersial speakers doesn`t appeal to me anymore. The Econo`s replace TABAQ with a 3" Tang Band, wich sounded lovely, but lacked "umpf". For my home theater I have built inConcert Miles (Beyma TPL-150H and two 15P80Nd), a speaker design from a fellow norwegian. The subs are two (soon four) Presicion Devices PD186 18".
    Teddy, I want to see pics of your Beyma setup.

    Hey, no need for the cough . Clever solution / application. Results look great. I would never have thought of that.
    I have seen some beautiful cabinets that looked like they had some airbrushed art, but your solution makes me rethink how one might accomplish a similar finish. Thanks for a thought provoking finish.

    *cough* The finish is *cough* not pen work... It`s.....wallpaper... :rolleyes:

    Teddy - WE NEED BETTER PICS!
    Those look great, personally I tend toward dark anti reflective finished for HT type stuff but these are very very cool. Who did the pen work? Is that Sharpie?
