Re: Shiva X extended bass shelf
The pioneer has a sub amp built in, mono only, with adjustable gain for all speakers.
It's only a stop gap measure to utilise these till we get the new place built with dedicated room,
The pioneer is 120 Watt per channel. I tried to get it tuned as low as possible as I don't know if the amp has any LPF built in to prevent over-excursion.
As for the box, I have no real plans yet, I would consider getting a sonotube to minimize footprint.
A large box won't fit in the room as it is. I had contemplated using the fireplace and chimney.... but a sonotube may be the best bet as we currently have ten foot ceilings.
