Looking for JBL 4343/4344 projects
« on: 22 Nov 2024, 10:57 pm »
Good Afternoon, friends. 

I´m looking for JBL 4343/4344 cabinet project . I´ve been tried to get it for many years but I could lnot find them ! I cannot access the Lansing Heritage users to send private messages to the main individuals involved in the projects. I have searched the entire site, but surprisingly, although there are many photos and discussions, I have not been able to find the cabinet designs with exact measurements so that I can reproduce and build my own speaker box. I cannot directly contact the key users of the site, and they do not allow new members. Only members can contact each other.
Regarding the main drivers, I have been purchasing them over many years. I still haven't managed to get a crossover design or the original crossover, but I believe I can find someone to guide me or someone selling an old crossover as well.
If you manage to obtain the designs for these cabinets, could you kindly send them to me so I can analyze them and start this great project? My email is matheus.soares@gmail.com or mattbh@live.com.
Thank you all, and as I have been digging through everything I can for many years, I thought it best to seek help from friends who might have been through the same situation.

Thank you

This speaker will offer you too much hard work.
Its a complex speaker, the midrange have a small sub-enclosure, four way cross-over and in the end it will be a copy.

The woofers are Alnico?

@FullRangeMan and @Arthur Dent ! So many thanks for your support.

My woofers are Alnico . What do you think that maybe be sell it and go ahead to JBL 4345  with a 18`` ?

If the woofers are Alnico the sound will be very good.
18 inches woofers are not suited to home music use, a 12 or 15 will be enough.
Good luck :thumb:
