Hello all. So you think your triad sounds good ? MEH? Do what I did. I did a lot of research into 3 way cabinet design. Was told by some that running the 15 full range was a no no (JBL thought it was all right for a lot of their cabaret line though and others) and that the 10 inch was/should really be a midrange and that there was a hole that could not be filled, etc., etc. So,,, I investigated 1st order, 2nd order 3rd order and 6 inch mids, and coaxials,. I still may replace the 10 with an eminence 10 cx and put the horn on back of it and then use the horn hole for a six inch closed back and then do some other crossover bandpass stuff I don't want to mention yet. But for now,
I took the haeavy snot 15 out and the chinese made looking 10 out and put them in the empty box that my new EMINENCE 3015LF and my new DeltaliteII 2510 came in. The 3015LF to my ears does not need a low pass filter because it already has a very good one built in, (THE voice Coil). Mr. Jerry said that the best box size he could imagine as posted on his site for the 3015LF just happens to be the same size as the triad box after the 10 incher box volume is calculated out. Its perfect. Now the 10 inch box? Hmm, seems its the perfect size for what Mr. Jerry sez is the optimum size for the Deltalite II if you cross it at 100 Hz. The stars have aligned its already crossed at 100! Coincidence? More like Karma!! Now I tried my 3015lf in several boxes nearly
the perfect size (the triad box is THE perfect size. No dice
breecause my amp will only put out 300 watts into 8 ohms and so it was way too quiet. BUT, wait a minute running that 10 down makes it 100 Hz of 4
ohm funky junky nasty thick sweet bass. and since its a first order thingy it rolls off and the 10 does not get too much bass and also the 15 gets 4 ohms until one octave below 100 or so (1st order when it really needs to have a computerized speaker management thingy (not) BUT the 10 just works beautifully to cause the 15 to draw 4 ohms specifically ONLY when it needs it. NO more no less. But wait the 10 also sees the amp in reverse in the mirror because of the 15 so it gets pushed as well. Perfect and I think it sounds real good. My amp does 450 into 4 ohms with an additional 3db headroom and so both speakers are liken it. Thought about changing the crossover for the tweeter but when I made a loud slap on my high string? That cabinet slapped me
I am not lie ing to u.
So now my triad is more than twice as loud because of that cabinet making my amp see 4 ohms and
the way better newer more modern techology neo drivers
. They did not have these drivers around in 1992. Honestly after I took the old speakers out, I picked the cabinet up to see how light it was without the speakers. It was feather light mabe 25 pounds in feeling pounds. So I put the speakers in and when I picked it up I thought, it STILL weighhs like 25 pounds. I actually can now stand over it, pick it up from the rear with one hand on each handle, and go up and down the stairs. i CAN LIFT IT OVER MY HEAD LIGHT, LIGHT, LIGHT. It does not sound shabby either. Matter of fact, it put a big fat grin on my face. Especially since I got the cabinet 3rd hand used or something. So now its just fresh all new neo new! Anybody else got some more that they did to one to make it even better?
