My first impression of the S3012 was that this thing is a S3010 turned up to 11! I also mean this in a literal sense because I had been running the S3010 gain at 1 o'clock and I had to turn the S3012 back to 12 o'clock in order to level match them.
Everything about this sub so far seems to push what the S3010 was to the next level. The biggest plus out of this being a substantial increase in accuracy of the bass. So far it seems much tighter than the S3010, which I honestly found to be a bit muddy. The bass also does not seem to hang around in the room as long. I am definitely not ready to say that it is as accurate as my Rythmik subs are but it may honestly be pretty damn close.
There is also a noticeable increase in both mid-bass and ULF here vs the S3010. This sucker feels more violent in the room with me than the S3010 and the slam I felt in my chest when John Wick was destroying NPCs with his shot gun was extremely satisfying. In my sealed 2000ft^3 HT the ULF this thing puts out definitely outdoes the FV18 and the mid-bass seems to be a bit stronger too.
I will preface this by saying I have not talked to Tom about this yet and there may be an easy/simple solution for this issue. I will be contacting him on Monday to get his thoughts on this issue.
These subs have a LOUD audible hum when the amp is on and the AVR is muted.
This is my 3rd model of sub from PSA and I have never had this issue on the first two. I've usually set the gain between 12PM-3PM on my S3010s and I have never heard a single peep of sound from them when the AVR is muted. At 12 o'clock gain both of my S3012s hum like I just plugged a guitar into a studio amp that is cranked up to 10. It is badly distracting and if this is what the final product is supposed to be like I think it cheapens these subs to the point where I might consider returning them. I have never had a single ground loop problem in my HT and the S3012 was plugged into the AVR and outlet the same exact way my S3010 always has been. I also tried several other cables, outlets, and outputs from the AVR just to be sure. The humming would not go away no matter what I tried.
I hope this helps some of you out who were waiting for some first impressions on the new Neo subs. I will make sure to update everyone after I am able to speak with Tom about the humming!
Great review...!!! I've had my S1512 for nearly two weeks and share the same impressions and experiences as you... including
the very audible buzz/hum.
Try this... If you have your S3012's built-in crossover set fully up to "bypass" (like most users should), turn it back just enough to engage the crossover (150Hz). If it's behaving like mine, your loud buzz will transition to just a faintly audible hum. It will still be there, but no where near as annoying. Engaging the crossover at 150Hz should have little no effect on it's performance.
I did notify Tom of this via email and he did confirm that programming the DSP for these new highly sensitive drivers has been quite a chore. They are working on reworking the gain structure in the DSP which should help with the buzzing/humming.
Like you, I've tried every possible thing that I can do, up to and including turning off the radio transmitters in my wireless router, and nothing
eliminates the buzz/hum. This is unfortunate for me because my room is on the smaller side and my sub is close to the MLP.
After days of pulling my hair out trying to find the source, I finally had an epiphany moment... When all of my equipment passes through the same AC line filters (which also eliminates DC offset); and no "common" sources that cause ground loop are used; and no
other subwoofer used before the S1512 has shown the same issue (using the same cables and power) and the noise floor of the system as a whole (other than the S1512) is dead silent... then why am I chasing my tail...?
Since your experiences mirror mine, please do
send that email to support. It's always good for them to know when there's more than just one person that see's the same issue in similar situations.
Other than for this one single issue, which I'm hoping Tom can rectify, I absolutely am in love with my S1512. I've never owned a Rythmik, but this is without a doubt the best subwoofer I've yet to own when it comes to downright "musicality". Outstanding mid-bass detail and punch with no apparent overhang.
I live in a townhome where my dedicated "media room" is a nicely appointed basement, so I can't be a ULF junkie (without involving local law enforcement), but this little gem surely checks all of the boxes that are most important to me...
