Hello. I was hoping someone here could help me ID the model number of this vintage RSL ported three-way speaker.
Appreciate it.

Hi Ed, here is what google says:

The speaker in the image is a vintage RSL (Rogersound Lab) 3300 studio monitor from the 1970s, featuring a 3-way passive design with a prominent 12-inch woofer, a 5-inch midrange driver, and a tweeter on a dark baffle with a wood-veneer cabinet. [1, 2, 3]

Thread 'Anyone own RSL 3300's?'

Jun 13, 2022

I picked these up at the used record store in town for just under $200. They seem to be in pretty good shape and they play flawlessly. My question is does anyone have any experience with these? There aren't any currently for sale anywhere online and specs on these are hard to find. Anyone have these? Love em'? Hate em'? Let's open this up for discussion! Thanks for your help guys.

Hi Ed, here is what google says:

The RSL 3300 pictured looks to have a thicker wood boarder around the grill cloth. The RSL cabinets I posted do seem to have the same driver load though.
Here is the crossover.
Notice the two adjustment knobs.

Yes I noticed that in your pic,
I also noted that your port is not painted.
Maybe a few too many screws in the mids.
Maybe someone replaced the motor board?
Early model? I am sure someone smarter than me
will be along shortly.

It appears the RSL 3300 was made in several different configurations. Here's one where the crossover is under the woofer and the port is on the right side under the tweeter.
