I just received my SVS 16-46PC, which I added to my M&K 7.1 system, including an M&K 125 MKII sub. First, let me say what everyone who has an SVS sub already knows - it is awesome. I am astounded at what a difference it makes in my setup. The addition of the 16-46 to my system is like the difference between having no sub at all and then adding one. I have only played a few demo disks so far, but the tank scene on SPR and the pod race on TPM blew me away. Is it silly to be a little bit afraid of a subwoofer? Also, once I calibrated the levels and played some music, I was also amazed at how much better music sounded on my system. There was much more bass, but without any boominess. I feel like I have to listen to my entire CD collection again, and watch all my DVD's over again. Way to go SVS! (I'm not going to mention anything about SVS customer service, as anyone who has dealt with them knows they are great to deal with and any compliment hardly does them justice.) Now to the questions. First, the output of the 16-46 is such that, to calibrate my system, I had to turn down the subwoofer output level on my TAG pre-pro to -9.5 db. Does this seem unusually low, and is there any problem with lowering the subwoofer output on my pre-pro tha much? The SVS manual seems to say that this is the best way to control the overall subwoofer volume, as opposed to turning down the volume control on the SVS sub itself. (The volume control on the SVS is at about 6.5 on the 10-line volume control. The volume control on the M&K sub is +3 db, which was needed to balance the system.) Second, I used a test CD and a Radio Shack SPL meter to take readings at various levels. I adjusted various things until I came up with the following readings, after adjusting the RS meter. (I have set my Tag to crossover at 80 Hz.) I'm wondering whether these readings are such that I should not really need to tweak much more, or whether someone thinks that I need an equalizer or one of those Beringer units. Here's the measurements. Are these good, bad, so-so? 20 Hz = 70.2 22 Hz = 75 25 Hz = 79 28 Hz = 82.5 32 Hz = 78 36 Hz = 85 40 Hz = 82.5 45 Hz = 84.2 50 Hz = 85.5 56 Hz = 80 63 Hz = 84.8 71 Hz = 81.6 80 Hz - 73.5 Thanks in advance for any help.
