Found the bass culprit in my monitor speakers...


Hello to you all. Months after months of changing the positions of my Leema Acoustics speakers only to hope to get better frequency response and bass output that was always lacking and missing in some certain frequency points. And then I hit this wonderful idea - let’s see what is inside. After opening the back of the speaker and admiring a really nice component crossover I took out about a 50cm long and 3cm thick acoustics wool out. The wool was literally stuffing almost 90% of the whole inside cabinet. Crazy (?) - and now this - after taking out the damping. More bass, more clarity, the great sound has come back again. Now the question - why did they stuff so much wool inside ? I think this is the main point why the users complain about bass output in Leema speakers. Secondly, I can suggest to anyone to experiment with damping inside. Sometimes it is not necessary at all I think. I think it is in closed enclosure speakers but not so much in back reflex port as mine ? I wonder what you think...

Bozak did use acoustical stuffing inside their speakers. The walls and back were covered in a half inch thick padding that was stapled to the inside of cabinet.  I should know, I sold and replaced many a woofer and tweeter in Bozak speakers back in the 70’s.

Sadly, Rudy Bozak is no longer with us.  I met him in the early 70's.  I drove my company's truck to The RT Bozak Manufacturing Company on Connecticut Ave. in South Norwalk, CT.  I was picking up an order of speakers and I met him on the loading dock!  He showed me around the entire factory (They made all their own drivers) and even treated me to lunch at a Greek diner down the street.  What a nice man.  He had some talented engineers, they are probably all gone now.
