speaker xover design/testing

Hey Mozartfan,

Well I used to, but ask your question over at DIYAudio, maybe with more details.  Also, Madisound will do this for parts they sell.

Best,
Erik

Danny Richie at GR Research. He does x/o work for commercial companies, his own products of course (DIY loudspeaker and sub kits), and consumers.

+ 1 for GR. The problem is he needs the speaker to design his crossover.

Any other way, (unless he had your actual XO fix on hand). Would be a shot in the dark at best... He'll want the box, might be able to get away with one. BUT the XO won't have a final tune, left to right, in case there is a slight driver variance. He might match. Not sure really. When drivers are not matched, the XOs can't be the same..

That is the real trick... Surely close enough for the majority of folks, though.

Regards

I was going to say Dennis Murphy but he's retired.  Jim Salk is handling the BMR legacy.

Richard Gray just cked the new xovers va the Thor schematic,,l, put it on his ociiiscope all parts cked good, then he straced the soldering against the schematic and found the tweeter  resistor was not soldered to the tweet caps, 
got back home , hooked up the xovers, all is now working fine,, 
'But 2 new tweets are on the way, and will request Richard take his mod on the Linestage  back to Jadis ' original design.
, The new Mundorf caps has added such bass, sounds  like a  sub woofer on certain ref cds, like Sophie Milman, 
The new Mundorf supremes one 8.2 uf Supreme + one 10uf Silvergold Supreme, = offers huge slam.
These lil  W18's are producing a  *smackdown punch slam*. 
But did not care for Richard's mods in the Linestage. 
anyway, just giving some updates. 
madisound made some superb xovers,, I had to purchase and ship 2 M caps which they did not have on their site.
The 10uf silver gold Supreme  and the EVO OIL silvergold 2.2uf.\
The 10uf Supreme Silver Gold Oil retail for $220 each,,I picked up the pair , used on Ebay for $230. 
But can't really telll just yet on new tweet xovers, til Richrad takes out his mod and new Millennials' arrive.
I am selling both old Thor xovers and the pair of Millennaol's with new voice coils if anyone is interested.
Both  Hovalnd xovers tested >perfect>, and the Millennials, are only slightly *mismatched, * but have 2 brand new voice coil diaphrams.

MillennIUM's , not IALS. 
anyway,, we will see just how new tests vs the 17 yr old (silent for 10m yrs, as my system sat silent due to no cash fora  Jadis or hifi preamP), btw that Chinese LS9 Jadis Clone really gave the stock DPL a  run for its money,,although the LS( did have Mcaps installed. Those M caps really makea  nice gain in resolutions.
. So new Millennium's vs 17 yr old Millenniums. 
will post a  note.

@Mozartfan

crossovers should be tuned to your ears not the designers ears. When you buy a pair of trousers, whose size do you buy them in? Yours? Or somebody elses?
