Midwest Audio Fest

It’s that time audio enthusiasts! Registration for the 2019 Speaker Design Competition is now open! Visit midwestaudiofest.com for details and to list your speaker project. We are excited to see all returning participants, and look forward to meeting some new designers this year, as well! Be sure your plans include a visit to the Parts Express Tent Sale for the lowest prices of the year, and the Audio Swap Meet where you can buy and trade with other audio fans. We hope to see you this summer! Vivian and Jill

    How would you build something like this:

    That what be an awesome studio monitor, but it is not worth that kind of money to me. What components would you use to build something equivalent?

    Exactly, as Bill F pointqed out in a recent post of a HP circuit, some call it a contour circuit. A good example would be if the tweeter
    (or woofer) is putting out too much midrange, you could set the active xo for your best response and add passive
    "contour" to make it even better.

    results for my clients (recording engineers). I am now listening to Satori 9.5" woofers and the Peerless
    DA32TX00-8 with a active XO and no shaping or eq and they sound pretty great. I can also recommend
    the Wavecor TW030WA11 and SB ceramic woofers for such a application.
    Does the shaping come after the speaker is built so that it can be measured with a microphone?

    I am forever in love with them. Transient response is outstanding. I listen to a lot of guitar and the attack [on the strings] it brings out on fast scale licks and arpeggiated runs is phenomenal. Cymbals hits are precise, distinct, and with individually discernable rolling shimmers that are characteristic of each of them.

    Tom -- I didn't consider that; thank you for bringing that to my attention. Would it make more sense to get a Protea unit (similar to a DBX drive rack, but more analog sounding)? I wasn't thinking I needed to get this complex, but you're bringing up a good point. Does it make more sense to build a passive crossover? I have the software and test equipment to do it, but never have.

    Take a look at the picture I have attached where it talks about the 'response' control. Would that help any of what you are talking about?

    Thanks,

    They state the Response control doesn't change the actual slope, so it still won't solve the fact that many drivers only need a 2nd order electrical filter to hit an LR4 acoustic target. Still way too limiting from my perspective.

    've never worked with the Protea - heard many good things about them but couldn't afford one back when I was doing live mixing. If it offers multiple options for filter types, some parametric EQ, and delay adjustment, you should be set. I worked with Charlie Laub's Active Crossover Designer back when I had a Behringer DCX2496. You might look into that if you haven't already.

    BEYMA 8P300Fe/N
    B&C 8FG64
    18 Sound 8MB500
    CIARE NDK8-3
    CIARE HW205
    CIARE FXC8-3
    FAITAL PRO 8RS250
    FAITAL PRO 8PR200

    I have this weird hunch (well OK, from all my testing of 10" midbasses, lol) that when Ciare says theirs is "low distortion", they mean it! I would be willing to bet from that list the Ciare would give all the rest a run for their money. As you can see, I like the "pro-audio" stuff, but I didn't just pick them because they look cool. I picked them because I like their T/S parameter set that they have. They have a T/S parameter set that is more "home audio-ish" than the other "PA style" T/S parameter sets. Namely lower Fs, and higher Qts.

    Choose your drivers carefully. That Ashley crossover will only give you a textbook electrical slope (probably LR4) and that rarely works to hit your acoustic targets. You can probably forget aluminum woofers unless you plan to deploy passive notch filters. The Ashley also doesn't provide any control in the time domain, so you'll have to account for driver offset some other way.

    You could solve all these problems with a miniDSP or like unit. Are you involved in Pro-Sound? Maybe pick up a used BSS Soundweb unit for cheap and learn to program it. The guys over at ProSoundWeb claim the BSS stuff sounds notably better than most of the lower priced DBX DSP boxes.
