Maybe we should crowdsource a crossover upgrade, and instead of the usual tubes, we’ll throw in a nice hotel grade towel
GR Research Baffle upgrade package!What remaining little regard I had for him completely evaporated when he lambasted the Yamaha NS-1000M crossovers as "pretty cheesy" and "it's bad, it's bad, it's bad".
Built from 1974 (nearly 50 years ago), the NS-1000M crossover is a low DC resistance design, metallised paper, self healing capacitors, multiple paralleled high quality caps and excellent terminals. And ferrite core inductors Danny, not steel core. The spring terminals will grip and hold bare wire between metal much better than his cheesy tube connectors.
And then you've got his 'measurements' above, vs these:
Quite different. Both made with a Clio system...I feel sorry for the person who had his NS-1000Ms butchered by that guy.
That's the nature of open forums, and such, ask more work for the moderator team is a big ask, however you can always use the ignore button and clean up what you read a lot.the ugliness you seem reticent to moderate brings dumb people to ASR who I don't wish to interact with.
@amirm
Did you try putting a wet blanket on it instead? That could've solved the problem once and for all
The thing is that the whole design is bad.I'd like tothank the Academyask the community if any of you would be interested in spending some time tinkering and try to fix this particual speaker?
If you are able and willing, we could send X-Voce for you to do as you please to evaluate and improve it (if at all possible). Perhaps, one of you will find the crux of the problem and help other owners make it sound better. You can keep the speaker - just publish your findings. Any takers?

Not knocking him, we all have to make a living.
Actually, I think that's exactly what Amir did.@amirm

Trying to answer your question :So Danny designed this speaker 16 years ago - why are you measuring an old, obsolete product? I don't get it.
The concept behind this speaker is flawed - open baffle midrange in a center channel? Open baffle & other dipole speakers need to be out away from the back walls to sound decent, and center channel speakers are usually parked right under the screen... so not away from the wall unless the screen is also at some distance from the wall...
I'd like to see the impedance curve for this thing, in particular the impedance behavior of those woofers & enclosures. Something is not right - the woofers are not in an enclosure that works properly with their T/S characteristics, or maybe those are just really bad woofers.
This thing might work better if you biamped it with a MiniDSP. Even so, the implementation of open baffle mids here is never going to be good in the intended center-channel home theater context.
This is disrespectful! Please let us keep things civil..Am I the only one that sees that the directivity was created in his own likeness?

This is all addressed in the video and text review. Are you just going by the title without watching or reading the review???So Danny designed this speaker 16 years ago - why are you measuring an old, obsolete product? I don't get it.
I come to think of if his crossover upgrade kits also change the response below 200 Hz? And if they do, nobody knows how?
Some of you know, my other mantra has been perspective matters. In that vein, if Danny's equipment was as good as Amir's Klippel, his look at this speaker would be so (1/3 octave smoothing with 25 dB scale)...

As you might expect, the response looks decent. The drop off at 200 Hz might look suspect but am using Amir's export and so is not gated as Danny's would be. With his gating resulting in less resolution, the 200 Hz point could have been higher and so lacked the drop off shown here.
So, from Danny's perspective, this speaker could have measured just fine. With enough expectation bias, could he have ignored the one-note bass? Maybe, but would not say a lot about his hearing in that case. Maybe he listened to it vertically or in a different position? Inquiring minds want to know!
If he does not have one to measure, perhaps the owner can send him this one?
