Genelec 8361A Review (Powered Monitor)

[Moonlightshadow]

I saw on another thread he turned down the opportunity to measure the Sigberg audio Manta. Would have been great to see that rather than another 8361a spin

Can someone confirm this? And if so, did Erin ever mention a reason for this?

Yes, @sigbergaudio posted it

Nothing dramatic I think, too long review queue was the stated reason at that point in time. If I can speculate slightly, perhaps Erin also wants to mainly review well known stuff to ensure he gets views and/or posts something his audience is interested in, rather than something from a relatively unknown brand.

All I'm saying is that 98% speakers are designed to be place as much as you can (1 to 3 feet) from front wall.
In my Elac tower manual also said that the distance from the front and side should not be equals because of cancelation.
Aso I found that SBIR of 45-50 centimeters from front baffle to the front wall will boost region of 50 Hertz.

On "the distance from the front and side should not be equals because of cancelation.": that is unreasonable. The actual frequency where the response "nulls", as one might say, depends on the angle of reflection, which again depends on the room size and orientation. What is implicitly gained with such an advice is that the speaker isn't pushed into the corner 8)
Better get yourselves a measurement microphone and real data.

Actually, the demonstration in West Hollywood is for the new 8380. I registered and plan to attend the event this Thursday. I don’t know what to expect, but I’m excited!

I always worry about how long active speakers will last. Spending 5k on a speaker that stops working after 3 years would make me insane.

Me too. But Genelecs have a 5 year warranty and tend to last forever.

That would be a big drag. There are few reports of these or any genelecs going bad long after warranty. It's one reason they hold value better than most brands.

You bought the philharmonic audio BMR tiers right? You'll love them. I like both my genelec 8361a and my philharmonic audio HT tower systems. They present very differently. At half the price of the 8361a the BMR tower is a monstrous value.

Do you have stats of how many of the millions(billions?) of the active speakers sold stopped working after 3 years?

Yes sir. Can't wait to get them here!

@dj94030 no stats needed for my own fears. I never claimed it was going to happen.

On "the distance from the front and side should not be equals because of cancelation.": that is unreasonable. …

Generally rooms are rectangular versus square, so statistically the numbers should not be the same front and back and side to side.

One can start with things that based upon some knowledge like standing waves. And then use some empirical methods.
Or
They can start empirically.

Moving a speaker to every spot in a room seems like a lot of measurements.
Personally I start off with what is known mathematically as one of the good choices and then start looking for a microphone and doing measurements,

 

[Heinrich]

They can start empirically.

Isn't the wave equation symmetrical? So, the role of listener's ears and transducer can be switched. Put the sub to where the listener would take seat, and take measurements with the microphone around in the room. Use noise as a steady signal. Look out for a location that gives a smooth spectrum. Then place the speaker there and cross check with the mike at the listener's position.

Does not work this way.

Genelec stocks spare parts for a really long time. They still service monitors that have been out of production for 20+ years

Well, we have 20+ year old Genelecs where I work that still work just fine.

Though those probably are not SAM monitors, just powered analog, correct? The capacitors in those are probably nearing EOL (end of life). With the SAM-based monitors, we have two concerns, primarily the DSP practical functionality lifespan and then the amplifier side.

 

[Heinrich]

You may want to give this prompt to a competent AI (which?); it will answer settled science from books, hence has a chance to be correct:
"consider acoustical wave propagation in a room, show mathematically (Green's function) that source and receiver can be exchanged, even when reflections occur"

I just remembered this as a piece from my education. Do you think of practical constraints? The math is a bit more complicated, let alone the formatting. It didn't fit here directly

I'm thinking of trying a Genelec One for desktop speakers. Dip my toes into the powered speakers.

Its nothing to try, 51s is the end game for desktop.
