I put my Meridian dsp 8000 se on usam once in awhile to test the water and there is very little interest.

Re: Active Speakers - will this time be different?
One of the companies that was always in active speakers is Backes & Müller from Germany. They make extreme high-end speakers. Not internationally famous I guess.

Active Speakers - will this time be different?
Yes, one of the more well-known active speaker manufacturers, especially if one lives in Germany.
From what I can gather, active speakers have gained acceptance in Germany and there are a number of active speaker manufacturers there. One of my go-to resource for active speakers would be:

Re: Active Speakers - will this time be different?
I thought the YG active speakers sounded very good when I heard them.
If I went active ATC would be at the top of my list.
Someone mentioned price ratio, not sure how they do it but seems some of the brands can achieve good sound. I would think ATC uses their own amps but not sure.

Re: Active Speakers - will this time be different?
I think active is a good way to minimize cabinet size regarding bass, and eliminates the worry of component matching, but I listened to the atc active vs passive demo at axpona, last one b4 covid and tbh I didn't notice a difference in the 5 minutes it took to swap speakers

Re: Active Speakers - will this time be different?
That isn't inherent to passive speakers/components. In fact, the opposite, since "midbass" falls in the frequencies where the front baffle becomes small relative to wavelengths being emitted, resulting in an on axis loss aka "step" in output as the waves simply wrap around the baffle.
If a loudspeaker has a midbass hump, its by design. Inadvertent or not. I think a lot of audiophiles misread Stereophile plots...

Re: Active Speakers - will this time be different?
nearly every ported speaker design has a 10 db rise around 100 hx and if I'm reading you correctly you're saying because the wavelength is larger than the baffle it, what ? evaporates?? please expand.
The thing about those measurements is they are pretty consistent.KEF Blade, Mc-611's, C49 rega jupiter, roon nucleus, revox tuner. Meridian dsp8000 se upgrade, meridian 218 zone controller VA Beethoven's, Hegel h360.

Re: Active Speakers - will this time be different?
10db??
Where are you seeing this Steve, link?
Random sample, latest passive bookshelf review at SPhile:
That's a 5db "hump" completely due to the nearfield measurement (mic <1 inch from woofer cone), as it states in the review just below graph:
The black trace below 300Hz in fig.4 shows the complex sum of the nearfield woofer and port responses. The boost in the loudspeaker's upper bass will be due to the nearfield measurement technique, which assumes the drive-unit is mounted in a true infinite baffle, ie, one that extends to infinity in both planes.
Again, most audiophiles simply don't understand how to translate the measurements. That's there by design, its often called "baffle step compensation" (Google it). It has zero to do with any inherent feature of passive crossover components. Its by design, yes of course, using said passive components. A typical active (home audio) bookshelf will have it also, via EQ. Studio monitors may/may not, due to different placement requirements, atop mixing consoles, etc., rather than free standing.

AJ

how about the jbl 4357? I ,look at floorstanding designs that attempt deep bass, your examples have nothing to do with my initial question

Re: Active Speakers - will this time be different?
Presume typo and you mean JBL 4367. Perfect, thanks. Stereophile measurement using nearfield woofer technique
Per JA:The nearfield response of the woofer (fig.3, blue trace below 350Hz) has the expected notch at the ports' tuning frequency, which is when the back pressure from the port resonance holds the diaphragm stationary. The 5dB peak in the upper bass is due entirely to the nearfield measurement technique, which assumes the drive-unit is mounted in a true infinite baffle, ie, one that extends to infinity in both planes.
The "hump" has evaporated .
It is an "artifact" of the measurement method. JA doesn't/can't measure LF anechoically to get an accurate measurement, so he uses the correct alternate technique....which obviously leads to confusion unless one has read his measurements method article, buried somewhere on Stereophile. He does, as I quoted above, note it with each review.
Once again, no 'hump' is inherent to passive speakers. Just individual design. Not defending them, as this type of 19th century tech is one of many reasons why I came off the sideline and started rolling my own. Just wanted to set the record straight.

AJ

Re: Active Speakers - will this time be different?
Point taken but what I really meant is perhaps related to the phase issues at the crossover points. I don't claim to be an expert on these things but I thought this (the mid bass "hump") was how passive speakers were affected at the crossover frequencies - the actual effect depending of course on the crossover network design. I've since been informed that this can also be heard as a smearing of detail or even a thinning of the sound.
p.s. Please leave out the graphs and snark on here. This isn't ASR.
If you say something nicely enough we will believe you. Honestly.

Re: Active Speakers - will this time be different?
I have no doubt that had they been faster at swapping the speakers out I would have more readily noticed a difference.

Re: Active Speakers - will this time be different?
Unfortunately neither, except above the transition frequency of a couple hundred Hz where "speaker" dominates. Below, its entirely predicated on the rooms dimensions, construction/rigidity/lossiness of surfaces, placement, seat, etc.,along with the speaker design itself.
In the case of the wide JBL with 15" woofer, there is significant forward beaming of the response, which means it holds up ok about 200 hz (where even a 15 stops beaming):
.
Something like your narrower Blade (yes, I know side mount woofers) will go omni a bit higher, so you will see room effects correspondingly higher in frequency.
The good news with both is that you know they are somewhat even (monopoles) LF output prior to any room effects.

Re: Active Speakers - will this time be different?
You're probably talking about the different types of crossover filters, affecting one or both of amplitude or phase. It's succinctly described and illustrated under the Common types section of the Linkwitz-Riley filter Wikipedia entry. I would not expect a speaker designer to pick a "wrong" crossover filter.
There is typically a time-offset between the different drivers of a speaker's different crossover sections, seen for example in Stereophile step response speaker measurements, which I would expect you could eliminate or compensate for using only active crossovers and the appropriate DSP. But I can't recall ever seeing a published measurement to confirm that.Neko Audio

Re: Active Speakers - will this time be different?
Yes the crossover network used affects amplitude and phase at the crossover points. It's not that the designer uses a wrong crossover intentionally of course but is forced to make a design choice as the behavior of the crossover elements vary as frequency and temperature of the elements fluctuate. In actives the drivers just don't see the crossover.
There is a nuance here i.e. time coherence and phase coherence which gets used interchangeably. Time coherence is when the drivers are acoustically aligned. All crossovers, active or passive, affect phase. But yes you are right in that crossovers can be designed to be phase coherent.

Same speaker, the nearfield measurements and in room. as an end user the second is easier to understand and looks much better. This pic does support your comment that JA's measurement doesn't really show actual response. I would rather see more of the second set of numbers as a consumer.KEF Blade, Mc-611's, C49 rega jupiter, roon nucleus, revox tuner.

Re: Active Speakers - will this time be different?
Stereophile is one of the few publications that show both "at speaker" and "in room" response. However the caveat will be "that" room.
The measurements at LF should inform "how low" can you go, but not much else, especially in room.
Circling back, some active, especially typical studio monitors etc may have built in adjustable bass eq. Imperfect, but a start and better than none.

AJ

Re: Active Speakers - will this time be different?
That brings us full circle, end result going active is the ability to eliminate the in room mid bass hump.

Active Speakers - will this time be different?
Not all active speakers enable the user to EQ the inputs. Eg, for ATC, it’s straight through.
While not a recent “white paper” and possibly self-serving, coming from an active speaker maker, this provides some perspective:

Re: Active Speakers - will this time be different?
I am taking a months vacation rental and couldn't be without something to listen to so I bought a pair of Cabasse Pearl Akoyas because of ease of travel and completely self contained. I'm not traveling for a couple of months so I set them up in my office which is as bad as it gets acoustically , square dimensions. After letting them room correct and some break-in time they perform way beyond expectation. I have now bought a second home in the meantime and don't want the complexity or expense of the type of systems I have now to bring to the new house. Given my Experience with the Cabasse Pearl Akoya ,their bigger brother the Pearl or a pair of Piega 701 wireless are on my radar. .
