Thank you for this detailed response! I understand most of it, such as test tones and spl meter and adjusting the knob. I tried my phone with the test tones. My volume was at 75, but my speakers were only showing tops 70dbs, and it was really loud to me.Just read the manual for my BP 9060 Floor Standing LR, it says to put it on Large in Receiver. I have two VTF2 Mk5s, should I be putting my LR 9060s on Large? Sub manual says otherwise. I have the 9060s plugged in, which I'm assuming is necessary to enable the subwoofers, so if I set them to small, are they only serving as speakers and no Low Frequency? Also, should I put the volume at 12 oclock even though my subs are at 9 oclock? I'm sorry for the amateur questions, but I am struggling with settings on my home theater setup in terms of setting for my receiver and speakers.[/QUOTE
1) No. Set to small starting with 80htz crossover. You can experiment up/down from there but your HSU's are going to produce 80 and under better than the powered woofers in the DT's without localization. So place the HSU's where they play the best in your room, within any placement limitations of course. Manual comes from DT marketing department. You can ignore it.
2) No. The crossover is not a brick wall. 80htz is just where they will start rolling off. They will still contribute down to 40htz or so, just at an attenuated level. They will also be playing 80 and up to the internal xo point (350htz, or so???) and do so with plenty of headroom and low distortion.
3) No, not necessarily. Best bet would be to try and level or gain match the bass on the DT with the bass knob on the back. Target 75db at your listening position with an 80htz test tone. You can use a SPL app meter on your phone if you have nothing else. Level matching is the easiest way to go here. Just adj the knob until you get 75db for each one. Each speaker might not be the same setting on the dial. One might be 11 oclock, the other 2. You can find test tones on youtube of you dont have another source.
Enjoy the process. It takes time. Especially getting the low frequencies right.
What really trips me up is the “crossover” talk. I understand it is where the receiver will stop relying on one speakers at a certain level, but I just don’t know how or what to set each speaker/sub at?
