Help with audio question...Sub woofer.

[Jayfro]

Given that the sub-woofer has a 16" Driver, I would lower the crossover point to somewhere around 80 - 70hz so you can't "hear it", frequencies around 110hz+ are audible which will then allow you to "locate" the speaker...you don't what to be able to locate the speaker/sub-woofer, you want it to disappear or blend into the main channels and room. Also, at higher frequencies, the bass becomes "muddy" and at some frequencies you can actually hear voices from the sub-woofer...big no no!

Also, since it has a 16" Driver, it is very hard (lets call it impossible) to "control" the actual driver since it's so large...meaning when the bass note stops (from the source) the driver is still moving playing unwanted bass. Many years ago, Velodyne had an accelerometer attached to the voice-coil that would physically lock the driver and stopping it from playing unwanted bass, but they're gone now.

I have my sub crossover (12" velodyne hgs) around 75hz for movies and I'll manually adjust it down to around 60-50hz if I'm listening to music...which will give me tighter/punchier bass than being up around 75hz+.

The best thing to do is play around with the different settings and figure out which one YOU like...and placement options (front corner placement gives you more bass since it's coupling with the floor and the two walls....between the left and right channels gives you less boomy bass since it's coupling with the floor and the back wall).

One more thing, if the sub is new, it will take about 30-40 hours to break in, after that period you'll need to readjust the volume and possibly the crossover points again, slight changes not huge.

Thanks Jay my SVS replaced a velodyne servo f series
F1500 very old but loved it. my cross over is set at 80hz
right now and it sits in a corner. What do you think about
the Isolation feet.

I’m not one that knows the audio language.

Jim,

I sold many of the F1500's (and ULD's, HGS, F's)...and I still have a F1200, and love it! To be honest, I've never used isolation feet so i cant really speak knowledgeably about them. Doing a quick search on the interwebs, the rubber pads will decouple the subwoofer from the floor which would in theory reduce the vibrations to the floor, where as speaker spikes couple the speaker to the floor. I would give it a try with a similar material before buying a set of "isolation feet".

I don't know who would kill me first my neighbor or my wife.

Been there. Once you get the first sub in the house the second one is easy. I have 2 of Power Sound Audio’s V1800 / V1801’s (18” speaker/driver), PSA is owned/run by one of the founders of SVS. If your interested check out avsforum.com for all things bass. The power sound audio subwoofer thread there is terrific, one of the best anywhere, can learn so much about setting up your sub for max enjoyment

Thank for the lead

Did a little more research and it seams the Isolation feet
will not help as the floor is a cement slab per SVS;
if anyone is curious.
