LS90 Question

vilbig

I had posted several months ago about a set of damaged LS90's I picked up at a local thrift store. With the great help on this forum. I was able to determine cabinet dimensions, crossover schematics and replacement driver options. The enclosures have been completed. My question is, since the backs of both cabinets are damaged/missing, I am unable to tell if this design was sealed or ported. And if ported, does anyone know the port size or tuning?

Thanks in advance.

Definitely ported. Port at the bottom of the back just above the x-over/binding posts. I am at work but I will be happy to measure the port dimensions later or over the weekend.

Thank you - it definitely helps with placement. I'm guessing it is a 3" port, comparing it to the terminal cup.

I used to have a pair but never measured the port.

Crap dude, I forgot all about you. I am going to be out of town this weekend at JazzFest in New Orleans. Shoot me a PM next week and I'll see what I can figure out for you.

Sorry - being a noob, my post count is not high enough to PM. Thanks for the offer.
