schmada,
Sorry, I was typing my response and didn't realize you had already replied.
If you are going to look at different speakers, you should definitely look for speakers that were designed with high bass output as a goal. This will probably require much larger cabinets and drivers. You might also want to consider some vintage speakers that were popular at the time the SX-1050 was on the market.
That said, I'm using vintage Infinity RS 1.5 speakers in my system, but using modern electronics. The Infinity RS 1.5, RS 2.5 and some others used the fantastic Watkins woofer which has dual 4 ohm and 2 ohm voice coils. They produce very solid, and loud, bass. My medium sized RS 1.5s play down to 28hz and can do bass very loud in my medium sized room.
