IME, I always found that a good high pass filter greatly improve dynamic and clarity on small 2 way monitors.
Best method to connect subwoofer to amp
I just finished a great post about my speakers and amp clipping sensitivity, impedance etc. highly educational, as I am a rookie in this hobby just starting out. One recommendation coming out of that discussion was to contact my manufacturers. I have a Jamo c 80 sub (1800 watts and with an adjustable crossover from 0 to 200hz) for two-channel stereo. the c80 has binding posts for speaker cable connections for spades and banana plugs. The c80 also has" Line in left/LFE and right.. My integrated amp is a Technic SU-G700 and its manual says to connect the sub to its pre-out left and right connections.
Listening to Paul McGowan ( PSAudio poobah) he says the best way is to run speaker cables from my amp to the speaker terminals on the JAMO which is my current practice. He says this ensures the same signal going to my main speakers (Canton 9k stand-mounted) and the sub are the same helping them disappear. As noted I am currently using that method and indeed my subs vanished.
However when speaking to JAMO the rep said the best way is to connect the amp and sub is through the Preout of the amp to the Line input Left /LFE and right of the sub, my Technic manual also says this.
There is no high pass filter involved in my system the integrated amp sends the full signal through the pre-out not confirmed by Technic but from what I’ve read. I mention this as my amp is only 70 watts and I would have loved to separate the bass to be driven exclusively by the sub so my main speakers could be relieved of that duty and as I understand it two benefits would occur 1 my stand-mounted Cantons would no longer have to play the bass and 2 more power would be available for the cantons.
It should be noted the canton9 k have two sets of speaker terminals on set for medium and high frequencies and another set for bass. I will not be buying a separate highpass filter at this time.
Given the above which is the best method (for musical benefits) to connect the sub or does it even matter which of the two options I use given my system?
Is one method safer to use than the other?
Am I missing anything I should be aware of?
Thank you for your help

It should be noted the canton 9k have two sets of speaker terminals one set for medium and high frequencies and another set for bassThat is for Bi-amp/Bi-wire, nothing to do with subwoofer connection. Given the above which is the best method (for musical benefits) to connect the sub or does it even matter which of the two options I use given my system?It is system dependent, my suggestion is try both way and let your ears decide, what sounded best is the best method. If you can't hear any difference, I suggest go for line level connection, I think your integrated amp has the option of remote turn off the pre-out, which is good for late night listening. Is one method safer to use than the other?IMO, line level connection is safer, you have less chance to shorted the speaker cable. |
My goal is to stop the low bass from playing on my stand-mounted speakers so they can concentrate their efforts on the mid bass on up.If that’s your goal, a high pass filter is a must! Since your integrated amp not possible to insert a line level high pass filter, your only option is to insert a pair of speaker level high pass filter between the speaker and integrated amp speaker output. SU-G700 speaker output --> speaker level high pass filter --> Canton 9K You can find some inexpensive speaker level high pass filter at Parts-express for experiment: https://www.parts-express.com/100-hz-high-pass-4-ohm-crossover--266-460 For best result, I suggest Bi-wire configuration: Disconnect the jumper bars from the Canton 9K speaker terminal, connect the speaker level high pass filter input to integrated amp speaker terminals, output to Canton 9K low frequency terminals, connect the Canton 9K high frequency terminals direct to integrated amp speaker terminals, so the high frequencies will not go through the speaker level high pass filter. If you like the result of this setup, you can upgrade the capacitor in the speaker level high pass filter to Film Cap to further improve sound. https://www.parts-express.com/pedocs/tech-diagrams/266-460--crossover--schematic.pdf |
