For setting up a full digital 7.1 system, I wonder which powered subwoofers are available currently with some sort of digital input(s), whether that is S/PDIF, AES/EBU, or something else. However, please exclude the sub-$300 PC-oriented boxes (Logitech, Creative, Cambridge Audio, Boston Acoustics, Altec Lansing, etc).

The ones I know about, are:
- Meridian SW1600 and SW5500 (MSRP USD 4.5K and 6K), with S/PDIF in+out
- JBL LSR4312SP (Streetprice USD 1K), with S/PDIF and AES/EBU in+out

Any other ones that are still manufactured at the moment?

not sure this it's your intended configuration but how would you configure a sub with a digital SPDIF input and a typical 7.1 or 5.1 receiver? With the channel decoding in the receiver, wouldn't it need a dedicated digital sub out? Does that exist in any receiver?

The Meridian processors will do it.

The Meridian processors have discrete "Speakerlink" digital outputs. Are they SPDIF? I thought it was a proprietary protocol designed to interface with their speakers only.

Wish it was available in Marantz or Yamaha receivers.

They are AES/EBU. The TacT processors also output digital.

Like others mentioned, Tact and Meridian provide digital outputs. The Tact MCS MkIII (USD 15K) has HDMI inputs and up to 12-channel AES/EBU and 12-channel S/PDIF outputs, while Meridian also offer (HD621) HDMI hook-up and AC12's to convert Speakerlink to S/PDIF (+/- USD 30K together).

JBL has the processing, room correction, etc build inside the speakers/sub (communication via CAT-5), and includes a mic, and/or through PC-control via USB hook-up. It also includes a remote to control the entire systems power/master-volume/source-selection/etc, and basically most functions that are normaly controlled by an external receiver.

You can also hook the sub and speakers (7.1) up digitally through a 4x S/PDIF modified HDMI-switch (Clux, Octava), BD-player (Oppo), video-scaler (Edge), etc. These modified boxes don't do the processing (except for the Oppo) or room-correction, however, they would make a nice combo with the above mentioned JBL-system, which takes care of those parts. This combo could also be a more 'affordable' (+/- USD 5K all-in) alternative to the Tact or Meridian (USD 15/30K +7.1 speakers), in respect to a full 7.1 digital system.

Any other subs with digital inputs?

Since there were no more responses last week, I think it's safe to say that the JBL and the Meridian's are the only digital subwoofers on the market, currently. If somebody knows about another one, or one that is coming up, please post it here; thanks

Hi Gekke, this may be a bit late but Genelec have a superb range of AES/EBU driven subs and fully corrected digital loudspeakers.
