    Okay I have my tempest and some extra cash left over from tax return time and i want to tame my tempest with the Behringer Feedback Destroyer, but I have little know how of setting it up and getting it right.

    So my set up is an Onkyo TX SR500 reciver, with my tempest using the PE 250 plate amp, in a 9 cu foot enclouser. the room i am currently in (dorm room) is approx 15X10X8 with laminated floors and a thin rug, i know its no the best acusticly but i can manage

    I have done a nice google search and found this great site that seems to have tons of info. I actually haven't read it all the way through.

    My questions are

    For the guys that have it, is it really worth the money?

    How was the set up? simple took you 20 mins/day/week/still haven't gotten just right

    Where can i find a decent price on one, and what modles should i be looking for, is there more then one?

    Also whats your experience with them?

    Thanks in advance

    Yes, they're worth the money.

    You can get them for about $120. I bought two of them from Lentines. Get the latest DSP1124P. Their website shows it as a DSP1124P ( http://www.lentine.com/pa/equbeh.stm ) and then the link says it's a DSP1100. You will get a DSP1124. Zzounds.com also has it for $119.99. http://www.zzounds.com/item--BEHDSP1124P I've bought things from both places. No complaints here. I'd buy it from whoever is closer to your house, or charges less shipping (if you don't care exactly when you get it).

    Absolutely worth every penney. I'm using both left and right engines on mine to control a Tempest and a Shiva. Here's some great info on setting one up. BFD Comprehensive Setup Guide

    what does the new BFD have that the older one doesn't?

    also can you extend the EQ lower then 20hz? i looked through the PDF Manual and i doesn't seem likly, but on that page i stated he was using 16hz notes?

    It has 24 bit DA convertors instead of 20bit. I'd be surprised if you could still find a new old one.

    I couldn't find a way to set any filters below 20Hz.

    The effect of the filters goes below 20Hz, I believe, so if you set a filter right at 20Hz you will still get boost (assuming this is what you're after) down low.

    okay, how was the set up and getting the eq just right? how long did it take and was it simple for a person that has never touched one?

    Once you get the basics it's not too hard. The toughest part is working out what corrections you should be making, ie plotting your response.

    Once you have that, Anthony Gomez's program (check his signature) will give you a graphic look at what the various settings do.

    But as in all things, the more time you devote to it the better the result.

    I spent the better part of a entire day on mine. It took a while to figure out what impact adjusting a particular frequency has on adjacent parts of the spectrum. Also took a while learning what bandwidth to use. I probably tried 3 different profiles until I got one that was pretty flat. Stephen is correct. Adjusting one frequency whether it's 20 Hz or whatever will impact frequencies above and below that point.

    now for setup all i need is two 1/4 inch to RCAs some RCA cabls, and the RS SPL metter? I saw a site where you could hook it up to a Wintel box and use software to change the eq, is that nesisary, simpler.

    I programmed mine via the PC, but it's not necessary. You'll need midi in and out and a Win98 box to do it. The software can be a pain in the butt to get working.

    I found it easier to just download the Excel Spreadsheet and plug in my readings then adjust manually. Radio Shack has 1/4" to RCA cables or you can make your own.

    Allen,

    If you are comfortable with Ebay you can get one of the old or even new ones for well under $100. For sub frequencies, I don't think you will see much of a difference in performance. I have an old one and it works just dandy.

    I did my setup in a grand total of three hours, and most of that was figuring how to manually program the BFD (use the FAQ and not the manual, the manual is confusing).

    To get the right correction profile, use the PEQ program (http://www.pvconsultants.com/audio/eq/peq.htm
    ). It can automatically correct for the RS meter, and lets you play with the frequency/bandwidth settings to get the curve you want. From there you only have to plug those values straight into the BFD. I did mine in one shot - no need for multiple tries to get it where you want it.

    Take care.

    yeah i was kinda swaying away from software like that because i have a mac, but i can deal with excel docs, just not .exe
     
  16. Allen, the EXE is a self extracting zip file. if you need an unzipped version, let me know. If youhave AOLIM, we can just file transfer it.

    now that i have orderd my BFD should i get the LCD SPL meater from RS or just the analog, also those adjustments we all talk about, are they for the digital one or the analog one?
     
  18. I use the analog...well..I used the analog...but now I have TrueRTA and a mic/pre setup [​IMG]

    afaik, the corrections are for the analog.

    Get the analog one. If you want to make life even easier, you can use the RS meter as a microphone with a computer based RTA system. Like Anthony, I use TrueRTA (www.trueaudio.com), but there are many others.

    You can download a demo of SpectraRTA from www.spectraplus.com . These programs will make your life much easier because you can do all your measuremenst in one sweep.
