Help me understand how to optimize bass on the Zu Definition Mk IV
Hi guys,Sorry for the long delay in getting back to you. With the nice weather arriving, my focus has shifted to outdoor chores and adventures!I did get the amps back from Sean and clearly the bass amplitude range is much more serviceable now. I s...

Looks like the sub amps are headed back to me. I'll report back in when everything is up and running. Did you end up deciding to get your amps upgraded to fix the hum issue, Marc?

By the way, I've also installed Isoacoustics Gaia I's to the Definitions. Can't wait to get the amps back to take them for a test drive! Sean said it was about a week turnaround.

That's great, Marc! Maybe this thread will end up solving problems for both of us :)

Hi Phil, Here's some answers to the questions you posed:-- no cable TV in my sources-- no balanced / XLR cables-- preamp is a Cary SLP-98 with integrated tube phono stage, no SUT-- no ground lift switches on any components-- no passive components-...

Very true, Marc, I'll start from square one with setup once the amps are back. I really appreciate all the help you and Phil have given me here. David

Yeah, I'm not too interested in spending much on power cords etc. at this point. I was just interested in the grounding posts you had installed on the Zu's and your overall power management scheme, as I've struggled with some hum and slight buzz i... 
Help me understand how to optimize bass on the Zu Definition Mk IV
Totally true, Phil, I was just curious where Marc has gone with his power upgrades. I still have some work to do to reduce some background noise in my audio chain, particularly when using my turntable as a source. I agree that the subs are the lea... 
Help me understand how to optimize bass on the Zu Definition Mk IV
Can you tell me more about the power upgrades you are describing? I've found a simultaneous benefit and drawback of the high efficiency of these speakers is how much they reveal noise issues in my system, including very minor ground loops. I had b...

Hi Marc, when I spoke with Sean yesterday, he also said he generally liked a lower setting around 38-42Hz as well, depending on the setup and type of music (lower for music with deep synth bass, for example). He said he has never had a need to pus...

Hey Phil, I actually have older spike receptors from Herbie's that I've been using with BDR cones, similar but different to the one's to which you linked. But in the interest of trying something new, I've ordered the IsoAcoustics Gaia's. I learned... 
Help me understand how to optimize bass on the Zu Definition Mk IV
I've managed to remove the sub amps and will send them out today. It was a bit of a challenge pulling them out due to the glue tape! I was surprised how tiny the RCA cables from the speakon inputs to the amps are. Flies in the face of the massive ... 
Help me understand how to optimize bass on the Zu Definition Mk IV
Thank so much, Phil. I really appreciate your help here!Interestingly, I did try higher crossover frequencies (along with various settings of the parametric EQ) over the weekend and it was definitely an improvement. I'd still like some additional ... 
Help me understand how to optimize bass on the Zu Definition Mk IV
Thanks for the info! I do realize footers are less important than getting these speakers properly set up at this point. I was just curious to hear about your experience using roller blocks, since I have a couple sets kicking around. I never though... 
Help me understand how to optimize bass on the Zu Definition Mk IV
Marc, while I was waiting for Phil to come back with info about the bass gain (keeping me in suspense haha!), I was reading some of the threads here and elsewhere about the Definitions. I noticed that you previous had Symposium roller blocks under...
