Lampizator P17 OBs

I never knew Lampizator did any loudspeakers.

They look interesting - and better in the new baffle. What are the crossover frequencies?

Here is a thread I started 5 years ago, about the crossover

Hi Chris, I have read all of the Audio Circle thread you linked to and it found it extremely interesting and informative. Tweaking these things really is a bit of minefield. Despite having tinnitus too I have no problem with the Mid and Tweeter response, it is the LF that for me seems to intrude too far up than I would like. One of the posters said that the LF goes up to 900hz.

I have spent too many years DIYing stuff and tweaking components and often chasing my tail around and around to faff about too much with the Lampz, but I might try some different values for the caps and inductors on the LF to bring it down to 6 - 700hz.

Have you finished tweaking yours?

Lets just say I'm much more focussed and happy than when I started the process. Today I listen to, and enjoy, my OBs more than ever. I too found the bass drivers encroached much too far into the midrange, particularly with the 'cheaper' 15" drivers recommended on the vaious OB forums, which lack quality when playing up there. Unfortunately for me the Saba greencones did not cover low enough frequencies to meet the bass drivers in a good place.

So, I now run different more expensive 8" drivers that can hold their own at lower frequences and quality 15" drivers that intergrade effectively.
