Kali Audio IN-8v2 (Second Wave) 3-Way Studio Monitor Review

[Newman]

The FR before and after....whenever you are ready.

What about step response?

It's not great, but could be worse. Me and another poster were comparing impulse responses about a year ago. He had Yamaha HS5 and Kali LP6 from memory, and the Yamaha's were noticeably "tighter" (lower group delay). You should be able to find the posts by searching my history. But if you really want that perfect impulse, you should probably pay the price for speakers from companies like Neumann.

 

[Randyman...]

...but as a function of time, and that's something completely different than your usual eq. Physics and mathematics my friend, not just listening to music.

Do you seriously think that all physical phenomena can be explained by an equalizer?

I think it might be eye-opening to perform @Newman 's suggestion.

 

[ABC666]

I can only listen to it for 1-2 hours after get off work a few days a week. I don't use it at other times. Should I turn off the power of Kali in8 or keep it connected? Is it bad for the sound system if I keep it connected for a week without using it?

Does anybody use IN-8 v2 on midfield, with 2 subs for instance? My planned room is about 42 sq.m (about 452 sq. ft). Same question about RCA inputs. As far as I understood it could have some problems (ground hum etc.)

 

[SIY]

I ask those who understand what transient and speaker speed are. And that you don't know what it means is not my fault

Frequency response and time domain response are exactly equivalent and interconvertible via the Fourier transform (and inverse Fourier transform). "Speed" of a loudspeaker is directly seen in the frequency response, which is why Newman suggest to you what he did.

Theorem, i.e., proved to be universally true. If you don’t understand that, you need to hit the books before posting more nonsense.

 

[Bartez2000]

This claim is absurd. It's the same as saying that all you have to do is make the exhaust louder to make the car go faster. Seriously, you don't see the difference? This is a different dynamic range of the transient - like the ADSR envelope. Not every speaker has the same efficiency, some don't react fast enough and have completely different dynamics. When the attack is fast and loud followed by its quick decay, the speaker sounds different than when the attacks are slower and weaker. Increasing the brightness brightens the entire signal, not the attack itself. That's why some sound gentle, others the opposite. Speakers cope with transients differently, regardless of the equalization. One speaker spits transients while another smooths them out. Static equalization doesn't change this, only a dynamic equalizer, compressor or transient designer could help a little here, but you don't even know what these devices are, because you only know the Apo equalizer. You raise the riverbed, not the water level, not distinguishing between these two concepts.

Indeed, using unbalanced inputs on IEC Class I equipment is pretty much asking for trouble. If unbalanced outputs are all you have, better use special adapter cables:

42 m² is a decently large room, what kind of listening distance would that translate to? My rule of thumb for an 8" is that it works well at about 2.5 m.

Tell me you don't understand the basics of Fourier analysis without saying you don't understand the basics of Fourier analysis.

What does the frequency response of a critically damped speaker look like compared to one that's underdamped?

Does this mean that speakers using single order filters = smoother rolloff = critically damped? Because that would explain why speakers with sharp cutoffs in their FR charts (Neumann, Kali?) tend to be underdamped.

 

[AnalogSteph]

The concept of damping generally applies to the low-end response, not the crossover.

Because that would explain why speakers with sharp cutoffs in their FR charts (Neumann, Kali?) tend to be underdamped.

Damping is, by definition, a function of amplitude and phase response at the low-end rolloff. How else would you determine if a speaker is underdamped? Also, strictly speaking, the discussion only pertains to 2nd-order rolloffs... with DSP you can increase filter order almost indefinitely and do all kinds of funky things. You can expect DSP (and active) speakers to be substantially EQ'd.

No. For example, in the figure above, ALL responses are second order.

what kind of listening distance would that translate to

Lounge connected with kitchen, listening distance about 3 m from speakers, but I plan to use 2pcs WS-12. Hope in will be enough to get reference level in MLP. About RCA - XLR adaptor - does it have negative?

Good question, from my experience, this doesnt remove any ground loops since its not real balanced?

And you still think that every speaker is equally fast and the solution lies in the equalizer? Well, Jean Baptiste must be turning in his grave...

Since I said nothing of the kind, why are you lying?
