| Help me understand how to optimize bass on the Zu Definition Mk IV Keep in mind, the sub amp is a Class D, with relatively low consumption requirements, and the amp has limited frequency duties in this application. You have far more influential opportunities elsewhere in the system to strive for more objective so... | |
| Help me understand how to optimize bass on the Zu Definition Mk IV David,The IsoAcoustics Gaia footers are rated for speaker weight up to 70 lbs per set. Definitions well exceed that, so the isolating compound may not as effective under greater mass.An alternative that is effective for me is from Herbie's Audio L... | |
| Help me understand how to optimize bass on the Zu Definition Mk IV Also, by the way, David: To remove your sub amps, note that the Speakon connector there is flange surrounding the connector itself. Start by removing the screws from the Speakon flange. The Speakon connector and its wiring harness stay with the De... | |
| Help me understand how to optimize bass on the Zu Definition Mk IV Definition 4 setup uses less toe-in than Def 1.5 and Def 2 in every room where I have heard both. Particularly in a relatively near-field situation. Both the Radian supertweeter and the FRD have broader dispersion than the respective drivers in t... | |
| Help me understand how to optimize bass on the Zu Definition Mk IV David,I was able to speak with Sean Casey this morning. Your Def4s definitely are early enough to have to original lower-gain sub amps. You have s/n 007/008; I have s/n 009/010. You have three options, one of which requires you spend some money.Fi... | |
| Help me understand how to optimize bass on the Zu Definition Mk IV You're well past it, Marc. | |
| Help me understand how to optimize bass on the Zu Definition Mk IV OK, David. I'll call Sean tomorrow and circle back. At 007/8, I am now certain this is your problem. I didn't get mine corrected because "9" gets me to the right spot, but if I moved while owning these I'd surely have to get the change myself. Sta... | |
| Help me understand how to optimize bass on the Zu Definition Mk IV The reason I asked about new vs. used is that in the early Def4, Sean set the internal amp's gain fairly low, such that in many rooms, including mine, the bass level had to be cranked to 8+, often 9, just to get in the realm. I pointed out to Sean... | |
| Help me understand how to optimize bass on the Zu Definition Mk IV For the OP,Are your Def 4s new or did you buy them used and they're simply new to you? There's a reason I'm asking. What are your room dimensions? Which 300B tube are you using in your SE amps?I started with Def 1.5 back in early 2005. Then Def II... | |
| Zu Druid 6 Well, let's see when I next get to the UK. -Phil | |
| Zu Druid 6 I have a semi-dedicated line for my main, Definitions 4 system. There are only a few other low-use sockets on the circuit. I have two Tesla Powerwalls supplementing my solar, and they are set up to power everything but HVAC for backup. To get the ... | |
| Zu Druid 6 So far, so good. With the caveat that it's great specifically with the KR 300B Balloon Glass, same as was true in my Audion Golden Dream 300B PSET. Which isn't inexpensive. But the KR is the only 300B that gets bass right and everything else is ob... | |
| Zu Druid 6 Not sure about getting to RMAF this year. That show has an uncanny habit of overlapping professional obligations that, of necessity, eclipse it on my calendar. But maybe.Phil | |
| Zu Druid 6 There is certainly latitude in the matter of SET bass on Druid 6. I'll say that even with Druid 4-08, the relative lack of discipline in most SET bass was easily discernible, but it was a small enough error to be OK,; euphonic even. In Druid 5, it... | |
