Full Range Subwoofer Connection

[BrettMendes]

I have a Marantz SR6006 with a set of Bowers & Wilkins CM1 bookshelf speakers and just got the Bowers & Wilkins PV1D subwoofer. I'm not sure what the best way to hook it up would be. If I wanted to do a full range connection instead of a Mono connection, would I use the front R&L connection on the 7.1 channel pre-out? Would there be an advantage to this? Its use is split pretty equally between music and movies.

Thanks,
Brett

No, there is no advantage. If you run "full range" to the sub and then connect the speakers to it, the high pass from the sub to the speakers is fixed (meaning the sub's x-over affects only the sub and not the speakers connected to it) and is likely at 80Hz. The CM1 appears to be -3dB at 55Hz, give or take a few, so an 80Hz x-over would be appropriate; in which case you would most likely end up with exactly the same thing so I'd opt for the receiver to handle that x-over rather than the sub.

Unless those pre outs are buffered, which almost certainly they are not, then your L & R mains will be mono, as you will have coupled the channels.

Best to use the LFE out.

You would effectively(if it's actually possible) just be handing a job the receiver was already doing, to the sub.

Some rel's are designed to use high level (l+r) input's
Alongside or instead of, the lfe input...pretty sure it's in order to connect up amp's with no dedicated lfe out's
