  • silverflute 8" sb29 2-way

    did some simming yesterday and this morning. both fr were created with response mod but they both have such a nice flat fr my confidence is high.
    have drivers on hand but will be a while before thaw allows time in the shop.
    woofer 4LR at 1500 4th order electrical. tweeter 4LR at 1800 3rd order electrical. 3ohms on the tweeter. this is obviously ported. i took out for bsl but forgot to put back room gain. should be an f3 of 70 or so and f6 of 33.



    thoughts, of course, are welcome.

    In your modeling, how big of a cabinet did you specify? Any thoughts on component costs?

        The dip in power responce at x-over is a little lower than it can be. That is a capable tweeter, try crossing it 100, 200Hz lower to make the gap smaller. It is ceetinly not bad, I am more picking nits here...

        The other thing is the tweeters responce out to 10K or so. You get a good rise in both power, and acoustic responce. That may get a bit much between 4 & 10K. Try a zobel to flatten out the rising respince. If it appers to roll off the top end, you can parallel a small cap and resistor to raise the top end only back up a bit.

        Overall, it really does look good!

          good advise thanks. the phase looks nice above the x, what about below, should that be of concern. the response would only come up a little.
          any other thoughts.

              I wouldn't worry about it, Mike. It's an 8" 2-way after all...

              Lowell-
              It looks good on paper. What I see is possibly a premature rolloff in the bass though. You got the frd/zma files from 'Brian', right? I sent them to him so you could have them. If not, I have them also if you want them.

              What's the schematic look like?

                C2 25
                L3 .90

                  I'll send them your way too...
                  Is C10 supposed to 'not be there'? If so, swap in a 99999uF value. Otherwise- it's waaaayyyyy too large for a tweeter cap.

                      You could send your files to me if you want... That shouldn't take but a minute to see.

                      Personally- I would try the files I sent you modified in RM, and see if things get any better.

                        You have to redo some work, Lowell. Your Z offset should be negative.

                        I will admit, I did that too recently, and need to update the Microtonnes thread...

                              It at least looks smoother to me...
