Subwoofers that do both L/R & LFE simultaneously?

Running a 2 chan/HT combo. I understand the REL subs allow you to connect both the stereo high level inputs and an LFE cable and the unit apparently senses the signal. You send the sub a full range signal. Any others do this? My Para s8's don't really need help on 2 chan, but it makes sense to me to use a REL type setup with the sub crossover at around 30. That way I get a little fill-in as needed. Am I missing something, why aren't all subs done this way. Thanks, this forum is great!

The Wilson Watch Dog has a processor LFE input as well as a stereo line input,....but you have to switch between them as you change from HT to two channel....not ideal, but it does permit two setups. By the way, I find the Watch Dog to be a terrific supplement to Watt/Puppies...similarly at 30.

Ruark sub allows you to do 2 channel line level and LFE at the same time and has two gain controls, one for each input.

I'm not really sure about your question, but in subwooferdom two is better than one. Never heard negative experiences with two rather than one sub. This guarantees you a balanced stereo bass. I used one sub for years 'til I switched to two, from Audiogon suggestions. I was released. As was my system. peace, warren

Not sure why all subs do not work this way, but suspect it is a cost issue. The speaker level inputs on REL go into a switch selectable filter. Purpose is to fine tune the integration of speakers and room with the sub. It is not really a crossover, as the filter has no effect on what is sent to you main L/R speakers. And then the REL sub mixes LFE and speaker level.

In any case, it works well!

With REL subs, the speaker (high-level) input is the
PREFERRED method. It integrates better than with
low level signal inputs.

I have two REL Strata III subs which I use with both my
home theater system (low level input) and with my two
channel stereo system (high level input). They are
excellent and integrate seamlessly with my Magnepan
speakers.
