Yes. And, thats why, if You take a look at waterfalls then even best CD-s does not look so nice below ca 1200Hz. It makes you quicly think that there has to be a crossover at 1,2kHz region and then it's already obvoius: need a 10'' mid.Originally Posted by Robh3606
One more cross, one more phase mess, how to make it all sing like one element?
Like You sayd Yourselt, Rob, when You buid Your stuff. Several CD-s measured same but sounded differend. Some nicely, effortless, some not - same graph.
I think ... I do not why but have such a strange feeling, there is a tiny possibility: JBL made some prototypes before they sent 9900 and 66000 into production line. I think this is a tiny possibility they listened them a'bit before, Yo
Thanks, but no thanks. Fellow Rob and Dr.db, I'll pass the 10'' part. Not because it's a bad suggestion but;
Two reasons:
- have in mind build up full system from zero: enclosures, drivers (buyable ones, new ones), dsp-board, Purify boards for higher, nCores(as they are bridgeable) for lows, all these all in my own-made racks. Plenty of fun ... I'd stay with 3-way this time.
- another reason (a good one): if JBL itselt already placed 15'' below CD in ones of their best contemporary systems, in ones best systems on the Planet, than I do not want to try be smarter (I'm not crazy) but just try to clone - or not even clone - but rather take hints from there, the arrangement.
The exercise I took is ALREADY higher than me. If I want to play it Ok I have to do nothing but avoid mistakes. Simple!
But mathematics says: the probability of errors is related to the square of the number of elements.
The speaker. One cross, on error-possibility. Two crosses - 4 possibilities. 3 crosses (4-way) = 9 possibilities of errors. Simple!
I think I'm not able to make it right. I'll go basically 2-way. Low end is supportive - in the region cannot be heard the direction of sound. And Dirac Live probably helps me as well with the last one...
These 'veneered monsters', is a 'calculated simlicity' however they look like comlicated monsters. if take it in 'molecules', it's a simpliest way system with fewest possibilities of mistakes - one important cross: a two-way system. 4CD+15W.
