Electronic cross-over on pre-amp out, to split signal to subwoofer and bookshelf speakers

This is very good feedback.

Let me share a bit more.

My power amps are Nagra VPA 50 W.  My speakers are Tidal Audio Amea (85/86 dB).

Both amps and speakers are excellent.  I am trying to reduce the load on the speakers, to have more power available for the midrange and tweeters. 50 W is not really sufficient to drive the speakers, and I am trying to have to avoid to buy either new amps or speakers.  Make the best of what I have. 😊

So a "High Pass" filter makes a lot of sense.  Install a Y connection on pre-amp out to feed the single sub-woofer. Use the second phono out on the preamp to a High Pass Filter that will feed the Power amps.

Please let me more regarding what you have learned in doing this.  Love folks sharing the brand of “high pass filter” they have installed successfully.  Any concerns?  Does this impact the pre-amp load positively or negatively???   Thank you!!!

I really like what I read.   You are all amazing!!!

My first test to establish baseline is to get cutover frequency and volume correct.  The speakers are flat from 100 Hz and up.  My room is pretty large about 15 by 30 feet.  With a 24 dB filter I am planning to start frequency setting very very low.  50 Hz.  Basically, sub contribution at 100 Hz will be gone and be "bookshelf" only.  I will use test tracks to get a sense of sound levels. 20, 30, 40, etc.  Make comparison with sub on and off.  Listen to digital recordings.  Get to a balances frequency and level.

I like the idea of filtering low frequency out early, post DAC.  Signal is already at a good level and get the low level out of pre and power.

Comments??

Electronic crossover will be second step.
