Spoke to a dealer about them earlier this week. The PowerPac 120 is just under a grand, around 960 quid. He reckoned the PowerPac 250 wasn´t available though, which I thought was a bit strange.
960!!! That's 4800 for five channels. A 9BST is much cheaper. I thought mebbe since you weren't paying for a fancy case it would be cheaper. Obviously not.
The pricing is all over the place. They want just over 1500 quid for a two channel 3B SST, the two channel 4B SST is around two grand or just over but the three channel 6B SST is over 3500! One extra channel is 1500 quid more, bit of a hefty jump! 300 watts per channel into 8 ohms though.
