j.r. Posted December 7, 2017 Share Posted December 7, 2017 Hi all, I just emailed this question to Klipsch support, then realized that there was a forum here where I probably should have addressed the question in the first place. So let me re-state it here. I just set up my new Klipsch r-10SWi sub. Wireless setup was automatic as soon as I plugged everything in, which was a relief. I thought the instructions were a little vague, but luckily not necessary. So, I immediately went to setting levels. My system includes an older Harmon Kardon AVR140 receiver, two (much older) Energy 2.1e front speakers and a new Polk CSi4 center speaker. The HK rcvr has crossover adjustments which I can't access due to not having the onscreen menu. But I'm trying to figure out two things: What is the diff. between the rcvr. crossover adjustments and the Low Pass filter adjustment on the Klipsch sub? Or are they the same thing? I currently have it set at 80 on the sub. Any more seems to be too much. (It's on the long wall in a 20 x 16' room with 8' ceilings.) Also, the gain level on the sub is only at 1/4 and it is already pounding. But for maximum efficiency of the unit, would it be better to increase the gain on the sub and lower it in the rcvr settings (which I can access) to get the most performance out of the sub? As I said, this is a pounding little sub. I just want to make sure I'm getting the most out of it. j. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted December 7, 2017 Share Posted December 7, 2017 If you use your receivers crossover turn the subs crossover to its highest setting. You won't get any more performance out of the sub by changing which components gain drives the subs amp to max output. The sub will do what the sub can do. Use an spl meter, calibrate your system and enjoy it. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted December 7, 2017 Share Posted December 7, 2017 I just reread your post and you said that you can't get to your bass management system. Download a manual or find a remote. You'll need that to get the most out of your receiver. Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted December 7, 2017 Share Posted December 7, 2017 A Harmony 650 remote or some other universal remotes would access the avr DSP. There is usually but, harder way to do it from the front of the avr.https://www.manualslib.com/manual/278895/Harman-Kardon-Avr-140.html Quote Link to comment Share on other sites More sharing options...
Peter P. Posted December 8, 2017 Share Posted December 8, 2017 I can't answer the first question but to answer the question about the 1/4 level on the sub-if you want more control of the sub level via the sub's level knob, then lower the receiver's sub output level. As long as the receiver sends a sufficiently strong signal to the sub to turn on any Auto Detect feature, you're good. Quote Link to comment Share on other sites More sharing options...
