mdrew: The SW300 is never kept in stock as for some reason it costs about USD $1100 in India. I've not understood the huge difference in prices. It is brought in only on order.

I did have a listen to the Opus 2’s in the demo room and they were really good. They play down to 33Hz which equals my M3s and SW150 combined. Maybe what you need is the Adire Shiva to be able to play below 33Hz down to 16Hz. I think the SW300 plays only down to 25Hz. That's what the dealer said.
