I used this item with a JBL L36 set of speakers being fully rebuilt and boxes restored new the only issue was the speaker was off by 1 inch so I had to cut a new whole a simple process speaker worked and sound fantastic as a midbass with a JBL LE 10 woofers it's also a 80-watt power upgrade for the L36 speakers which operates at 50 watts rms this build was a serious power upgrade adding a Bluetooth system to the boxes, so we got exactly what we were looking for,

I purchased a used Micromedia sound system (7000596) and found the cone on the subwoofer was almost gone.I did some research and found this 8ohm Goldwood speaker was the best fit. The physical dimensions were almost identical to the original. The only adjustment I had to make, was to widen the clip on the negative terminal.I am not an audiophile so I won't give an opinion on the sound quality but it did the job and I expect to get many more years out of this system.p.s. I have another Micromedia sub and the cone on that one is torn as well so it may be common for them at this age?
