    Re: Flex Your PCD Mettle:

    so, WINPCD is exactly the same but doesn't need Excel to run, and is faster? Wow, I just purchased Office 2007 to install on my machine just so I can run PCD. Luckily I didn't open the package yet

    I will download it and look at it later. If it's faster, that is good. I keep getting stupid security warnings every time I open pcd. So annoying. Thanks.

    I use winpcd which is the same as pcd except the fact that that it doesn't run on office and is faster. It actually has a schematic that shows the parts and where they are as you enter them.

    Re: Flex Your PCD Mettle:

    I found the schematic when I first opened it. I had obligations today so no speaker fun today.
    Thanks for the reply. I am proficient at MS paint, so can show where my stupidity is as far as PCD is concerned... :D

    Until that time, I am playing around with some Cerwin Vega woofers to see if I can learn how to use PCD7 and some of the more technical side of passive crossover design.
    I have gotten to a point where I am about to start entering data into PCD7 and am looking for willing participants to help me learn to enter the parameters on PCD7 as I see it on a crossover schematic. I am still new to crossover design and have reach a point where I need more help.

    I am using a generic econowave crossover, and not sure how to enter the values into pcd as I see them on a diagram/schematic. I have other designs I want to try out while also learning to play around with other options. I can't do that until I more knowledgeable on PCD.
    I have opened frd files for woofer and tweeter, and played a little bit with basic crossover points. But I don't know the more complex stuff like notch filters and what not.
    Even if I saw a schematic for a filter, I don't know how to enter it into PCD.

    I have been reading papers and what not by Wayne Parham and others that have direct experience with compression drivers. Some of the speak is a little too technical for me, but have still learned a lot from the info.

    I guess I just need help with applying information on PCD7 now.
    I read as much as I could find the last couple of days or so specific to compression drivers, and feel I am ready to start diving into PCD7 with some help. I am more of a hands on type learning, and need some computer time on PCD.

    Here is a link to my current project. I can provide ZMA and FRD files if need be.

    These woofers are only ok compared to a higher quality, high efficiency woofer like the deltalite II 2512 (the CV is similar to a Dayton Classic). But they will help me learn.
    Thanks to anyone who read this. :D

    PCD does have a schematic diagram to which you can refer.

    Post a shot of the "generic econowave crossover" and we can post a few screen shots of the way it would look in PCD.

    Very accurate fidelity but will be building subwoofer with AE TD-15H and a pair of passive radiators. The BMS compression driver and the waveguide are amazing.

    Nice choice of components. So how do you like the sound?

    Re: Flex Your PCD Mettle:

    Stuffing is covering the crossover and the sides are lined with acoustic foam.

    Nice looking enclosure!

    Do you have any stuffing inside? You really should add some if you don't have any. Standing waves will form without it. If you can attach a few wads onto that center brace, the mids will likely clear up even further.

    Re: Flex Your PCD Mettle:

    I just built the EconoWave Mini S-8:

    They sound GREAT. The efficiency, power handling, clarity and detail just blow away anything I've ever built using "home-audio" drivers. I should have done this a long time ago.

    It's nice to be able to play my music really loud and not worry that I'm pushing the limits of my speakers.

    Thank you Zilch. RIP

    DAn,
    Here are some polars I found for the HF94 and Hf96 by RCF. Both look really good, with the 94 loadnig easily down to 1K. What advantages do the PT waveguide and QSC152i hold over these. I know both are wider than the RCF version, but the polar responses look very similar. I guess this is getting into theory and why a wider waveguide is better if they seem to perform in a similar manner to the RCF square waveguides. Both the RCF guides are aluminum and seem to be very well made.
