Each episode is a lesson. Wonderful.

[@Billy123bobzzz]

Excellent, thank you!

[@glmaughan]

One reason the original x-over is boosted in the mid-band is so Wilson could increase their efficiency rating over the choice of a smoother fq response. Also rigid port tubes are resonant by nature. Why pipe organs use rigid pipes. I always roll my own port tubes using cork. That way the port tube is a rigid pipe at low frequencies but as the frequency increases, the cork is a great media for reducing resonances.

[@quant2011]

so you wrap cork around the port tube interior? will felt also work?

[@glmaughan]

No, it is pure cork. I use 1/8 to 3/16" cork sheet applying masking tape where the seam is on the inside with half the tapes width exposed so when the cork rolled around the former, the other edge is held in place with the inner masking tape. Then wood glue completes the bond. Then a second layer of masking tape is applied to the outside to cover the seam. I use PVC pipe for the former making sure that the cork is not too tight so once glue is cured, I can slip the cork cylinder off from the form. This compliant/flexible tube virtually eliminates most pipe resonances, yet at low frequencies the tube acts as a rigid structure. I first saw this cork port tube in Goldmund Dialgue speakers many years ago. I immediately understood the advantage of this design. Maybe Goldmund has a patent on this, I don't know. Since I only build custom designs, it doesn't effect me.

[@stephenyoud6125]

Cool idea. But rigidity at low frequency would be dependant on their resonan frequency. Once excited they will oscillate and wobble around at their resonant frequency.

The duette is designed to stand close to the wall, that is why they didn't provide it with a baffle step correction the roomgain would/ should balance this out.

[@anthonyjackson7097]

Close to the wall with a rear port? I learned that was not the way to place rear ported speakers.

[@Mark-rw3kw]

@@anthonyjackson7097 I don't know if the Duette was in fact designed to be close to a rear wall, but typically the mid-size and larger Wilson speakers are designed to be at least 4-6 feet from the rear wall, so "close to the wall" may be a relative term.

[@edjackson4389]

@@anthonyjackson7097 Totally depends on the speaker. If a speaker is weak in the low end or midbass, placing it 6" or so from the wall or corner will typically make it better just like @smaudi said. If a rear ported speaker is already fat in the low end it's best to keep it a couple feet away from the wall and avoid corners.

[@dannyrichie9743]

Even if that were the goal, they would have still had to adjust for the baffle step loss and create a more gradual decrease in output across the lower end to balance out boundary reinforcement. I might add that they also include a cable and a resistor for the tweeter designed for free standing use, on their stands, that the customer also owns.

[@anthonyjackson7097]

@edjackson4389 Yeah, I understand your point. I feel that using walls to correct baffle step is not the way to go about it. Minus 3+dB at frequencies right in the Fletcher Munson curve will not go unnoticed. For speakers approaching $15,000.00 a pair, what is another cap, coil, and resistor going to matter to the profit margin? While nice-looking speakers, there is nowhere near with stand included $15,000.00 worth of parts. Any manufacturer charging this kind of money should have baffle step compensation, Period! You shouldn't have to use the walls, like you own a pair of Bose 901's.

Just an additional FIY, while the crossovers are potted. There are a lot of binding posts, and internal screws, nuts, and washers connecting everything. All of the binging posts, internal screws, and nuts are either Copper, Brass, or Aluminum. However, there are two resistors above the potted crossovers that are connected using a connecting junction, and the resistors are held down with and twisted around steel screws.

[@condostereo]

For some reason factory positive and negative pairs always have the positive and negative running in the same direction. What if Wilson flipped the negative side on the “near wall” set to eliminate the room boom? I think they would measure exactly the same but sound different. I’m a fan of yours Danny! I am going to build a pair of your speakers some day. Love the videos!

Many recording engineers use monitors that aren't all that flat, or even ones that they would never use to listen to the music outside their work. Of course that doesn't apply to all of them but the point is that the important part is truly knowing the monitor you're using and how it relates to the sound you want to achieve.

@@carlitomelon4610 I personally am not a fan of Wilson speakers, simply from a price performance point of view (plus they are often butt ugly). However, I don't think the 2005 Duette Series 1 is an embarrassment. I don't know what you mean by fooled for 20 years. You can go back and read reviews of the original Duette Series 1 and see what others thought of the way it sounded. If you want to see a recent embarrassment, see the GR-Research original LGK (Little Giant Killer with one full range driver) and how it was reviewed on ASR and other sites. Fortunately, Danny released some new LGK versions that included adding additional low frequency drivers (and not just some crossover or other minor changes) to address the problem. What ASR revealed is that the tests that Danny does are not comprehensive enough, or do not include listening tests, to uncover a major flaw in a speaker system. Nobody in this world is perfect, and I think there is room in the audio world to appreciate both Wilson and GR-Research, regardless of whether their older products needed improvements. BTW, I didn't purchase a used Wilson. I am not a fan of 2-way "bookshelf" or stand-mount designs. I also not a fan of buying any audio gear that old.

Hey Danny. This quote from John Mark’s review in Stereophile mag may help explain the decision to not use Baffle Step Comp: “The Duette was designed to be used in nonoptimal placements, such as on a credenza or mantel, or in a bookcase or built-in cabinet.” I can see it in John’s measurements, and he mentions it also.

[@mcgovernjimmy]

I set the speakers up per the instructions in the manual... "Near Wall" resistors for 24" or less from front wall, etc. The problem is that even setup closer to the wall with boundary reinforcement, I still have to listen to them way off axis - pointed straight ahead. Even 10 degree off axis is fatiguing. If Wilson "intended them to be this way and let's not account for any baffle step compensation"... well, I don't like it. And now Danny has fixed it... The problem "hear" isn't the end user or improper setup. A good buddy of mine has a pair and he's doing the upgrade as well.

[@rehn1kri]

@@mcgovernjimmythanks for the response. I get what you’re saying, just maybe trying to help explain that portion of Wilson’s design choice (not that I necessarily agree with it). Enjoy!

[@dannyrichie9743]

If one were to design a speaker for close wall placement, the step loss still has to be accounted for. Then it is the ranges below 100Hz or so that are softened a little to mirror the gain of the front wall.

[@bakeone4406]

I've never heard Duette speakers, but it's obvious that the design of them is very different from most other Wilson speakers. As a result it's probably not possible to make a valid generalization from this video about most of their other products. I recently traded a pair of Spatial M-4 speakers for a pair of WATT 7 speakers and was surprised that the imaging and soundstage when going to a non open baffle design didn't change a lot. For sure the WATT 7 speakers delivered more low frequency impact. In my set up the Wilsons were on balance an upgrade. Not sure that would be the case if I had a pair of Spatial X-4 speakers.

[@1997inspire]

When you go to Heaven God is going to commission you you to fix his speakers. I noticed that the bass port opening is not flared. It is counter productive to use relatively expensive aluminium without flaring when ironically , cheap flared plastic tubing would have been far better acoustically.

[@dannyrichie9743]

When the port is just big enough for the application then flaring it will help as there is high air velocity. However, if the port is oversized for the job, air velocity is not an issue. So making the port bigger in diameter and longer (keeping the same tuning) reduces port noise as well.

[@Acoustic_Theory]

This speaker is meant to work well close to a wall, or even on an actual bookshelf. Compromises might have been made to account for near wall boundary loading, and at first blush it looks like the places where the response is 'sculpted' are consistent with that end goal because they are places where close boundaries would tend to 'thicken' the sound.

[@dannyrichie9743]

Even if that were the goal, they would have still had to adjust for the baffle step loss and create a more gradual decrease in output across the lower end to balance out boundary reinforcement. I might add that they also include a cable and a resistor for the tweeter designed for free standing use, on their stands, that the customer also owns.

[@mcgovernjimmy]

Have you owned / listened to the Duette? There's no "setup issue / he didn't do it right" going on here. The speakers are "HYPER resolving" with the original crossover. I set these speakers up closer than 24" to the front wall and used the "Near Wall" resistors... both per the manual. For my enjoyment, I had to aim the speakers straight ahead and listen to them way off axis, so they didn't melt my face. Associated gear is all top shelf Ayre Acoustics - QB9 Twenty DAC, Ayre KX-5 Twenty preamp, Ayre VX-5 Twenty amp. A friend owns the same speaker, and also a pair of Alexia.

What frequency do 8" drivers usually start to beam and ruin the off axis response? And do you need a big tweeter that goes lower to fix that?

[@dannyrichie9743]

Rule of thumb has been 1,500 to 1,900Hz.

[@haycrossaudio5474]

You can work that out by taking the speed of sound in meters per second (343) and diving it by the cone diameter in meters (0.2mt for 200mm). 343 divided by 0.2 = 1715Hz (1.715kHz)

[@mitchdowning8188]

There is a lot of skill involved in getting these well crafted and expensive speakers to show a desirable (linear) frequency response curve in an acoustically prepared testing room. Even after this is accomplished , they are not likely to provide the same performance in the listening room that they will be used in.There are factors of listening room characteristics, and where speakers are placed in it, that must be addressed. With a calibrated testing mic ( like the miniDSP UMIK-1) and REW software installed on a laptop computer, anyone can make measurements to determine how their speakers are performing in their listening room. The graphs which Danny displays appear to be slightly "smoothed", but that could be the result of testing in an anechoic room. ( Note: some speakers designers like Siegfried Linkwitz are said to prefer untreated listening rooms because their designs are meant to couple with the room environment.) There is also room compensation/correction software (like Dirac Live) which uses digital processing to optimize stereo and surround sound systems. This technology is relatively inexpensive and would certainly be something to consider by anyone wanting to make the most of their optimized, or not so optimal, speakers.

Our measurements are done using a gated time window that removes all reflections. So they are just measurements of the speaker only (no room). We use an industry standard 1/3rd octave smoothing.

[@mitchdowning8188]

@@dannyrichie9743 Isn't that degree of smoothing chosen by the industry trying to sell a speaker rather than analyze its performance? If this much smoothing was not applied, the response would appear much more ragged on the graphs, but could also be indicative of the accuracy/stablity of the drivers. So rather than just tweaking a crossover, repairing/ replacing a failing driver ( like a tweeter with dryed-up ferrofluid) may be indicated. How much attention do you give to distortion percentages? In amplifiers the odd order harmonics ( esp.- third) are thought to be most unpleasant to listeners. Is this also something of concern in speaker design? P.S. - Checked out your "Flat Speakers are Boring " video which gives a good explanation of some of the factors that cannot be ascertained by measurements alone.

[@dannyrichie9743]

@@mitchdowning8188 I often look at the measurements unsmoothed. You have to be careful not to get too hung up on trying to flatten out an unsmoothed curve. There are way too many little wiggles in the response that you just can't address. At some point you have to look at an average response. Real distortion measurements are hard to take, and have no standard. They also vary with level. So it is best to not get hung up on the numbers. You can't conclude that the lower the number they better they sound. We see this often in amplifiers.

[@robertt7238]

That is a way to simple view of the world and how speakers work. Anechoic on-axis response and room response are both important, but for different reasons. You can't simply get a microphone and REW and fix all that ills a speaker.

[@jamesmansion2572]

It seems that the measurement was with the speakers a long way away from a wall to get the full (nearly) baffle step loss. Is tha a realistic scenario to compensate? Would anyone have speakers like that in a room large enough to get that far away from boundaries? And would they put them that far away, given the lack of baffle step compensation?

[@mcgovernjimmy]

I listened to the speakers with proper setup, according to the manual. On-axis and 10 degree off axis were IN YOUR FACE. Pointed straight ahead was manageable. The quality / parts were worth making "right" to suit my taste.

[@jamesmansion2572]

@mcgovernjimmy I can believe it - just that I would have expected a fixed baffle step compensation to be less aggressive than 5 or 6db unless its something designed for free space placement. That the driver is forward is possibly a seperate issue. Also interesting that small changes in toe-in are having that impact, given that up to about 1kHz I'd have expected the off-axis response of the midbass to be fairly constant out to beyond 30 degrees - surely toe-in is normally tweaking trebble response from tweeter beaming?.

[@mcgovernjimmy]

@@jamesmansion2572 To make the speakers more listenable, besides pushing them toward the wall and pointing them straight ahead, I also pushed them further apart - to increase the off axis angle. "Free Space Placement" makes the issue even worse and I think it's why they provide a high ohm set of resistors to turn the tweeter down more. By the way, I tried the "Free Space" resistors with the speaker setup near the wall... opposite what the manual says to do. I tried to turn down the "in your face" property with that. All that did was keep them "in my face" and dull the sound. I think if you look at the measurements from Danny, it's the 1-2k area that is the big problem. It's not just the tweeter in that range... the woofer needed to be turned down there as well.

It appears that this is the original Wilson Duette Series I made from about 2005-2013, so that should be taken into account if considering a new speaker model from any company.

It's a high quality speaker that now has had the hands of a professional crossover designer on them. It's going to be a great speaker when it's all done. Stop making excuses for Wilson Audio.

@@mcgovernjimmy I am not making excuses for anyone. I personally would not buy a Wilson speaker for a number of reasons, as I have explained several times. But it is worth noting that Series 1 speaker Danny tested dates back to 2006, was upgraded in 2013 (Series 2), and was replaced by the Tune Tot in 2020, so obviously they know there are improvements that can could be made to the original. Making the 2006 Series 1 Duette a representation of the entire Wilson brand is the ultimate strawman fallacy since everyone knows that the other models made them well known in audio circles. Nevertheless, even with the improvements made by Wilson (and Danny), I am sure they sound pretty good anyway, especially when used as "office" speakers (what a joke).

I own a pair of Wilson Audio Sabrina X. Everyone is entitled to their opinions about what good sound is. I also think who are we to judge how people want to spend their hard earned money? Isn’t this hobby about enjoying music and high level reproduction to get us (the listener) as close to the sound of the original recording as possible? I’ve always aspired to moving up and owning better quality audio equipment. For me that’s been part of the fun. As a long time audiophile who didn’t always have top quality gear, I appreciated all of it at every level. As there diminishing returns the higher up you go? Absolutely! But better is better. And these Wilson’s are the best sounding speakers I’ve ever owned. I’d be interested to hear if Danny thinks he could make them better?

[@dannyrichie9743]

I'd have to take a look at them.

[@mattholland315]

Sounds like you’re now terrified that WA have done a similarly cr@p job on your speakers and conned you out of $$$$$ As the Sabrina x are 3-way there is a good chance that the crossover between the woofer and mid has helped compensate for baffle step loss. But who knows? Maybe WA’s house sound is to have a non-flat midrange? I’ve never liked any WA speakers I’ve heard. Ugly and bright sounding. If you want to hear the music as it was originally created then you should seek out a speaker that has flat on-axis response and optimised directivity for accurate off-axis response. Check out anything that has a clean set of measurements using a Klippel nearfield scanner. This includes distortion measurements, something that Danny doesn’t publish in his videos, but definitely useful information about how a speaker sounds.

[@davep2945]

Matt, dude, seriously. He listened to the speakers and he liked them. He knew what they cost and he thought they were worth it. He still likes them. They didn't con him and he's not worried in the least that he didn't get his money's worth. And, really, on what planet would he be "terrified" of any of this? Do you actually live in fear that products you like and pay a lot of money for may one day be deemed inferior according to one man's opinion of it? Your opinion of Wilson is your opinion and completely irrelevant to anyone but you. Guys like you and Danny have this idea in your head about how a speaker should measure and if it doesn't well then it can't sound great. But, again, that's an opinion, not a fact. Danny knows how to make a pretty response graph and for people who think like him and have his taste I'm sure they will like his designs. I'm in the camp of if I like it then I like it. If I think it's worth it then I think it's worth it. Heck, for all I know the speakers I like may measure the way Danny likes them to measure. But if they don't then I don't care because I'm never going to measure them. Nor am I going to worry about whether some measurement wizard or one of his minions thinks I'm wrong. When he's paying for the speakers he gets a say. Until then he's just a dude selling his opinion.

@@mattholland315 Of all the measurements that can be made on a speaker, the distortion measurements tell you little to nothing about how a speaker will sound.

The same is true for distortion measurements of amplifiers. 1%, .1%, or .01% is not a measure of sound quality.
