Marshall 7152 Dynamic Bass Cabinet

Solid! That's what it is, no question. I bought the cab new in 2000 and use it with a Marshall 3520 integrated bass amp 200w MOSFET. Initially, I had problems. At mid-volumes the bottom end would fart and lose power. After seeking advice, I was told that the amp couldn't cope with the "low" impedance cab. The amp is rated at 200w at 4 ohms; I measured the cab and found it was 3.4 ohms, slightly less than the 4 ohms stated on the rear plate. I then rewired the cab - two 10" speakers in series, then paralelled with the 15". The resulting resistance measurement showed 6.7 ohms. I plugged it back ... more
