JBL goes Dirac Live ready and Class-D

When I say on sale, I mean for less than the normal price.

Got it
In my view, Dirac Live has always been sold short. In most cases, this leads to a significant step forward.
Other active and passive measures are not as effective and cost-efficient.

+1. Although I think what Dirac got right was the target curve and control. Audyssey XT32 with the iOS app or MultEQ-X were also compelling options but at this point, Audyssey lives in the unusual world where Audyssey is an independent company but the patents related to MultEQ XT32 are owned by Sound United so there aren’t multiple companies licensing the Audyssey tech.


Interestingly, there is 2024 activity on the old patents and in 6 years, the patents will expire allowing premium room correction to be implemented in more products.

@PatentLawyer
I know you don’t like to involve your work expertise here, but is there a quick and easy way that is generic enough to explain why there might be a need to assign a patent back and forth? Or does any comment on why you have assignments like this require an understanding of individual contracts?

Replying to @Doctors11 from the other thread:

I've now had a chance to set it up and... I'm not sure. I've tried doing to A/B testing with it on/off with various content and I'm not sure what, if anything, is different with the EZ Set EQ on. Sometimes I think maybe it's a bit more bass shy but a bit less muddy with it in, but then after some more listening I think maybe it's not different at all, actually. If there is any change, it's pretty subtle.

It doesn't help that the setup confuses me a bit. For one, it says to move around the room. But what exactly that means is unclear, as most of the setup is really. If they were going for making it easy for those totally new to anything beyond a bluetooth speaker to setup, they're really missing the mark. They need to revamp the setup to be much clearer, and enable it to automatically set distances and levels. I haven't really had to mess with any of this since I set up the Audyssey on my Denon X1300W who knows how long ago, but I'm not new to this bracket of audio. I still had some trouble with it. Here's my finished results according to the app:

Is that how it should look? No idea honestly. I have a big issue with this screen right here:

View attachment 396809

I'm assuming that "roll-off" is supposed to be for the subwoofer's low end if you have one, except for the front full-range measurement. Not really clear though, and they expect total newbies to figure out what to put there? Even worse is the lower part. How should one adjust that slider? It seems like you'd go to the right if you want more bass, since that's the positive dB side, but then is says you adjust it that way if there's too much bass? What? My assumption is that it should say "Want more bass?" for the right and "Want less bass?" for the left because what's there is totally contradictory. But even ignoring that, if you want to adjust it you have rerun the calibration each time which is a huge chore and makes it impossible to effectively compare different levels.

Ugh. Total mess IMO.

Hopefully Dirac goes on sale soon so I can not have to worry about it anymore.

Thanks for all your effort on this. I agree with your frustration of a product that aims for the plug and play customer...this is Far from that. That last screen shot is indeed confusing. I've read some of the complaints of the more expensive JBL line and many are frustrated at the lack of accurate instruction and timely firmware updates.

At this point, and wanting a slim model, I'll probably bite the bullet and get the Marantz Cinema 70s. It seems to check all the boxes except for not having the top room correction. I'll keep an eye open for sales.

Thanks again for all the info.

@GXAlan , the reason for an assignment that long after issuance is usually because of some larger agreement or corporate event, for example an acquisition, bankruptcy, spin off, etc. However, the assignments themselves are usually public and sometimes you can gather a bit more info by giving them a read.

Just on the sidleine:
What may be interesting about the mentioned patents, they are based on a resistor in the negative = ground connection of a bass loudspeaker, which gives a correction signal to a construction of filters. This principle is indeed so old, there should never be a patent granted in 2007. There is nothing new in it, just a random combination of well known principles. Normaly Chinese fraudsters do these "nothing new patents" to blackmail producers. Because of time an judicial costs, it is cheaper to pay the fraudster than to wait until a judge has rejected the patent. It also shows how incompetent the patent office is, granting patents to even the oldest ideas, wrapped in tech blabla and impressive diagrams. Maybe a little corruption is involved, from time to time.
Large companys like JBL are able to protect the market from new developments of competitors, by stopping them in their tracks. This one is aimed at any subwoofer with motion correction. Even if in the end this patend would be thrown out, it makes it too risky to market a new product based on this old principle. JBL could instandly stop sales of a product based on it, until the legal process is finished. This would make a smaller competitors probaply collaps due to the costs involved and this is what JBL patents this junk for.
Funny fact: JBL marketed subs with this principle, decades ago, in consumer subs when these were not as popular as today. So they know best how old it is...

Wait, did you mean Bose?

To the owners of the 7100, how is this AVR performing in normal use for Movies and music?

 

[SpoOokY]

It's great. Sounds good, has plenty of power and works as intended without noticable bugs.

 

[kyuu]

Been using it, works great so far. No complaints. I haven't yet set up the Dirac.

 

[Bentail]

Thanks Spoooky and Kyuu. There has not been much activity since Amir’s evaluation. I finally settled on the Anthem 540, but may be looking a second receiver for another room. Since I once owned on, I felt like I abandoned it too soon. I got attached to it. Thanks again!

Does anyone have the MA9100HP and can report back? In contrast to Denon/Marantz, it must be bursting with output performance in his price class.

Hi,

I am new to this forum but found a lot of useful information here already, thanks for that!

What I wonder: is there any measurement of the MA7100HP idle power consumption or could an owner maybe please take one?
Maybe one with a 4k60HDR video signal present on a TV but without audio (typical PC usage until you start a video/game) and one in idle only?
Why do I'd like to know that? Most of the time my AVR is waiting for audio while being idle (PC use) and the less power it takes the better for me.
Seeing class d amps made the hope of finally having found something fitting bigger.

Thanks!

I have an open box one coming in for a 60 day evaluation. Looking forward to trying it out. My Denon X3800 has gone wonky … just past the warranty period.

Far from an expert so the setup will be interesting as I am retired and want to avoid the cost of Dirac. I have my settings from MultiEQ so that should help.

Let us know how it goes. I've been living with the MA7100HP for some months now, so if you have any questions I'll try to help out. If you want room correction I'm not sure you can avoid the cost of Dirac. The only other option with these JBLs is the included EZ Set EQ, which IMO is firmly in the "better than nothing, but no substitute for a proper room EQ system" camp.

 

[Narnian]

Here is the space I am clearing out. Wife wants the fireplace back Ihave separate speakers (white on mantle) for the AVR. They might make a nice match for the color of the JBL.

Currently I am testing the Marantz M1 against my Arcam SA 20 with the Revel M105 speakers. I wanted a smaller amp since I will have less space and am surprised that, even though the sound is different I like both amps about the same. Never liked the Denon X3800H musically which is why I ended up with the Arcam setup.

I have the Arcam and Denon sharing the two SVS SB1000 Pro subs with the Denon using the LFE in and the Arcam L/R preouts using the other connections. Planning on moving to one sub also because of space.

I will also test the JBL musically and see if I can get down to one amp

 

[Narnian]

I just got theJBL MA9100HP to try for 60 days and so far the setup was very easy. The sound is very good in stereo with my Revel speakers and SVS sub. Roon works fine. Sound stage is very good and clarity is excellent. Very early in the testing and all jazz so far. Definitely better musically than my Denon X3800H to my ears.

Will do the calibrations later before I test movies and surround as that seems to be the major issue in most reviews.

Very nice. Don't need to post in both threads by the way, you can just pick one. I'd go with this one, since the other thread is the review and that thread is really supposed to stay on the topic of the review itself.
