D-MAN Posted December 6, 2005 Author Share Posted December 6, 2005 Great! just leave the fuse part permanently blank... BTW, the better analogy would be "training wheels", not "seat belts"! I suppose that you are going to hit me with the bill just about Christmas... Just my luck. DM[] Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted December 6, 2005 Share Posted December 6, 2005 Dana, I think maybe I should put a little disclaimer message on the board where the fuse should go. Just a little CYA thing! Al K. Quote Link to comment Share on other sites More sharing options...
D-MAN Posted December 6, 2005 Author Share Posted December 6, 2005 How about a little memorial plaque instead for all the poor little tweeters that are now put in harm's way due to MY BLATANT and TOTAL DISREGARD for their electrical safety?!

tigerwoodKhorns Posted December 6, 2005 Share Posted December 6, 2005 My Peach made a crackle noise one day and my ALK's fuses lit the room up (it was dark). I still have my K77's but I am out two fuses. Chris Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted December 6, 2005 Share Posted December 6, 2005 Dana, Ah HA! Now I see the problem... The fuse goes in the WOOFER circuit, not the tweeter circuit! [8-)] Al K. Quote Link to comment Share on other sites More sharing options...
D-MAN Posted December 8, 2005 Author Share Posted December 8, 2005 Hey, are we forgetting who is paying for these things?![] DM {edit} Horror stories aside, fuses degrade the sound. Period. I can't say anything else about it because I don't want to make anyone mad, and everything that I can think of on the matter would just do only that, and that is not my intention.

Deang Posted December 8, 2005 Share Posted December 8, 2005 Dana -- the plot below is labeled wrong. The top is 3x13, the bottom is 7x13. The second plot is raw response -- no network. Quote Link to comment Share on other sites More sharing options...
D-MAN Posted December 8, 2005 Author Share Posted December 8, 2005 Dean, the Jubilee plot (#2) I did have questions about, so thank you. {edit} in thinking about this, nobody would test a speaker without a crossover - you would blow up the high frequency drivers - so NOPE, Dean, I'm not buying it. But the first one (from SB article) is correctly labelled - it's the corrected version. Note the improved performance at 400Hz caused by the narrow(er) slot. P.S. - Al K - what, exactly is the point of putting a fuse on the woofer circuit? Frankly, it isn't the woofer that I would worry about. The woofer is cheap in comparison to the high-end drivers that I'm using. The woofer is the cheapest thing in the whole cabinet, and the high-freq drivers are independent! What is the point?! Seems to me there is none and that it's just HABIT. Fuses are OK for PA applications, not hi-fi! DM Quote Link to comment Share on other sites More sharing options...
D-MAN Posted June 2, 2006 Author Share Posted June 2, 2006 Hey, Mike, thanks for digging this thread out - I've got more to add to it now... As I stated before, the upper frequency bandpass capability of the bass horn causes problems with a low-order crossover which forced me to throw some money at the problem. Came up with this as a possible solution so that a first-order crossover can be used. The major consideration of this is that it is a driver-specific solution, but so is the ES crossover, now that I think about it. The physical solution is certainly cheaper, though. Haven't tried it yet, as I don't have a crying need for it (yet), but thought I'd post for youse guys... Dana Quote Link to comment Share on other sites More sharing options...
D-MAN Posted June 5, 2006 Author Share Posted June 5, 2006 PWK references using a front compression chamber in the 1945 Khorn patent which uses a 12" field-coil driver. The front compression chamber acts as an acoustic low-pass filter. Here is the general concept... Quote Link to comment Share on other sites More sharing options...
D-MAN Posted June 5, 2006 Author Share Posted June 5, 2006 The ability to place additional chambers with their attendant throat openings associated with specific drivers is just another reason to use a removable motor board. Quote Link to comment Share on other sites More sharing options...
