Genelec 8030C Studio Monitor Review

I have a WiiM Ultra streamer DAC and do all the job very efficiently and perfectly flat: have a room correction software you can use and tweak as you want with PEQ 10 parameters.

The problem of 8030C (Genelec G Three B in my case) is just its size: it needs a sub imperatively. I use Genelec F Two sub with sub output of the WiiM that allows to set phase, crossover frequency (85 Hz is recommended by Genelec) and delay, volume of the sub…

I corrected also the 2.5 kHz region, as measurements showed constant dip there, even changing positions.

With a subwoofer it improves considerably, not only the bass region but also the mids sound better (clearer).

How did you set up the Wiim to correct the 2.5 khz dip did you just run room correction and apply it manually?

Yes, I corrected a couple of modes (42 and 71 Hz) and some reflexions (159 Hz and small 330 Hz) with the room measurements (not used the inbuilt algorithm because it tries to correct everything and prefer limiting to < 400 Hz and only negative EQ), then enhance 2.5 kHz by 1.5 dB, 3 Q factor.

WiiM suggested +4 dB in that region, probably by measurement error, I chose 1.5 or 1.8 by ear. Also reduced the modes corrections too extreme, for example -8.7 dB at 71 Hz to -6 dB and so forth…

I love your detailed explanations mate they are so helpful so thank you for taking the time.

I sort of wish now I had picked a SAM model with GLM not savvy enough yet to iron out the problems with Wiim auto correction it just made everything razor thin with zero body to the sound using default settings

Personally I find formative to decide by myself how to correct the room once taken measurements. I got some advices of how I can do it and still learning on the topic.
The algorithm are approximative, you can verify how putting a little table aside the speaker or moving slightly the sofa the curve changes.

Only thing I miss from WiiM is the possibility of just measure with the correction you choose: if I’m right, each time one launch the room correction it starts from flat EQ.
 
can you cover the port holes on the back of the 8030c?
why some people do it? what are the advantages?
if you do want to cover the port holes , what is the best way to do it?
and with what materials?

Less deep bass. I guess that can be an advantage in some problematic rooms, but I'd personally prefere to deal with those problems in other ways.

I mean... you can just play a bit with the dipswitches on the back instead.

if you do want to cover them , or experiment with that , how would you do it in the safest way (to the monitor)? do you fill something inside the port holes?
what material would you recommend?

If you're so worried about damaging the speakers, I'd say just drop the idea.

Are you having any issues with the speakers that makes you think it's necessary to plug the ports?

The people at Genelec are not idiots. They didn't put a bass reflex port in the design just for fun.

understood
idea dropped
thank you for the information
 
I will probably plug the port on an 8040b destined to be a center speaker in a somewhat enclosed cabinet. I'll use acoustic foam cut to size.
 
can you tell me how much time before ISS starts working on the 8030c?
do you find this feature reliable? does it works consistently in the same way?
or do you usually turn it off?
 
Works fine for me. I think it switches off after 30min of no-activity.
Even a very quiet input signal is enough to wake them, so you don't have to blast the volume to get them going again.

When Genelec implements a feature, it works.

thank you Chris , that's good to know. plus the 5 year warranty reassures me also

Sure, not sure why you'd want to though.
why some people do it? what are the advantages?
There is some belief (accurate or not) that 2 ways should not be reflex designs (and there are some compelling reasons for it; port resonance leakages tend to dominate in the crossover region). But you gain so much SPL and linear bass extension that I wouldn't consider it worth bothering with, and the 8030 doesn't have any meaningful port leakage.
