Damien Posted August 16, 2017 Share Posted August 16, 2017 Hello, I have a stereo tube amp that has no subwoofer output. I have a Klipsch R-10SW subwoofer that has no banana speaker input. Can I connect the amp to the speaker output on the LFE input of the subwoofer? Is this a risk? Will the cabinet settings be possible? Thank you for your answers Quote Link to comment Share on other sites More sharing options...
baron167 Posted August 16, 2017 Share Posted August 16, 2017 Hi, my understanding is those are line level inputs only, so no, do not do that. Connect your pre-amp line level out L and R to those sub LFE and R inputs. Quote Link to comment Share on other sites More sharing options...

Damien Posted August 16, 2017 Author Share Posted August 16, 2017 Ok, do you have any advice for choosing a subwoofer? I have pregnant Sonus Faber Venere 2.5http://www.sonusfaber.com/en-us/products/venere-2-5 A tube amp: Specifications: Output Power: 12W x 2 Power tube: 6P3S x 4 (analog 6L6) Pre-amp tube: 6N9S x 2 (analog 12AX7) Output impedance: 4 ohms THD (harmonic distortion): ≤0.15% (9W), ≤0.50% (12W) Frequency response: 20Hz - 60KHz S / N ratio: 76dB Input Sensitivity: 0.7-1V Input impedance: 100K What are the factors to take into account to choose? I like the one:http://www.theater-solutions.net/sub10f.html Is it good with it? Quote Link to comment Share on other sites More sharing options...

Get the line level signal from there with some Y cables or adapters Quote Link to comment Share on other sites More sharing options...

Damien Posted August 17, 2017 Author Share Posted August 17, 2017 There is no exit Préamp, it's like the picture. The room is 25 m2, I have a budget of 250 $ max 300 Quote Link to comment Share on other sites More sharing options...
jason str Posted August 17, 2017 Share Posted August 17, 2017 The Dayton sub 1200 is a best buy if you have a tight budget. >link< The 15" version would be good as well. Both are in the budget you posted. Quote Link to comment Share on other sites More sharing options...
Damien Posted August 17, 2017 Author Share Posted August 17, 2017 Ok, thanks for the advice I'm especially looking for a subwoofer for music, not much for movies. I found a Theater Solution:http://www.theater-solutions.net/sub12f.html Is it good ? Quote Link to comment Share on other sites More sharing options...
Damien Posted August 17, 2017 Author Share Posted August 17, 2017 I just reread and understand, I speak English well. I use a Korg DAC, is this a pre-Amp? I can connect like this: Computer to USB DAC DAC to Amp and Subwoofer in RCA with 2 splitter Y ? Quote Link to comment Share on other sites More sharing options...

Maximus89 Posted October 26, 2021 Share Posted October 26, 2021 I've got a similar, slightly different question. I use an RSW-15 which has no hi level inputs. I use an analog multi-channel preamp with a sub out for my multi-channel HDMI DAC. Sub kicks on for movies and tv just fine and i can use it if i use the HDMI DAC for music, but it's just not as musical as the preamps built in option board DSD DAC which is only USB/Toslink/Coaxil inputs. I DO NOT want to lose the .1 LFE of my HDMI Dac for movies, but i want to add sub for 2ch analog simultaneously. Can i run a y adapter from the subwoofer and connect one to the LFE sub out of the Pre and the other to a y adapter to the back of the preamp output which will split one to a power amp input and the other will have the subwoofer input. As i understand it, i would get a 3db boost if i use L+R input from the sub, but it is not necessary and i wouldn't need to run 3 long cables(L/R+LFE). Will i cause an issue doing this? Thanks Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted October 26, 2021 Share Posted October 26, 2021 A "y" adapter FROM the sub? I'm not sure I understand your signal chain. 1 Quote Link to comment Share on other sites More sharing options...
