Zu Soul Superfly


I just ordered a pair of the new Zu speakers on a whim. I was going to wait for information, but the fact that they threw in the free superfly upgrades to the first 30 people got me.

From a similar thread it sounds like some of you guys have heard the speaker despite information only being released today. I'm wondering what you can share about it?

Also, I am really hoping it works with a Firstwatt F1 amplifier. Can anyone comment as to that? I know the Druid's and Essences worked OK.

I've found battery gear to be dull, boring. Don't get me wrong, I love the idea of low power and have the off-grid bug in me. That said there is something missing in the less than 3k components I've heard including RWA paired with Devore Super 8's. I listened less.

Just wanted to mention that.
>> I did not get the "more planted" sound that Phil refers to, my bass was just even more eaten.<<

Right, you won't. Druid and Soul are different. Soul has tall spikes and the finger vents in the bottom are insensitive to floor gap, unlike Druid. Druid on spikes in carpet -- takes some real attention to get right. Soul on its spikes on carpet -- simple.

Phil,

Insensitive as in "not as critical" or insensitive as in irrelevant?

I'd like to lock the spikes in place with the nuts but would have to raise the height for that.

Also I feel like presentation has been different higher vs. lower, though in fairness I didn't have it perfectly balanced when they were higher. I broke out the bubble level when I was working for the jewel case height.qqq
>>What is the appropriate height for the Superflys?<<

Hard to say what's going on without knowing more about your overall situation. Soul is intended to be fairly insensitive to floor gap; generally no user adjustment needed. In setting up a Soul Superfly system in the buyer's carpeted room, I found height adjustment proved both unnecessary and not meaningful, short of killing sound by taking out the spikes and placing the speakers directly on the carpet.

Meaning not critical, verging on not relevant. Large differences can have some effect but the design doesn't intend requirement for futzing with floor gap height. The Griewe scheme is now primarily internal via the cartridge and the finger vents on the bottom. You can find *some point* in the gap range where approaching no floor gap is not good but short of heading hard for zero, it should not be a critical factor. You need 1/4" gap or more. You'll notice in Zu's own photographs of the speakers, the spikes are quite tall.

>>Also I feel like presentation has been different higher vs. lower, though in fairness I didn't have it perfectly balanced when they were higher. I broke out the bubble level when I was working for the jewel case height.<<

Depending on many other acoustic factors you might be sensitive to differences in presentation associated with small changes in driver height. Or, as I said, if you head for zero on the floor gap less than 1/4", things will change. You may notice diffrences without having a clear idea which is actually better from a fidelity standpoint. No one can tell you what you're hearing isn't heard, but from a physics standpoint, Soul's design removes the floor gap from performance influence from 1/4" and taller.
