What DID WE DO with the $8,000 Magnepan 3.7i?

[@davybloggs1564]

As a LONG time Maggie owner, I know how poor they sound when new, and how long they take to break in/loosen up. I would have thought YOU would know this too! So, I'm amazed that you did your measurements, with the intention of altering the crossover values, BEFORE they were completely run in!!! The bad looking initial frquency sweep you took, should have been a warning sign to you that things were not right. A brand new Maggie, or ANY new speaker, should NEVER be measured, for any comparative reason, least of all if you're going to seriously alter/modify anything within it!

[@danielm6507]

That doesn't have anything to do with how poor the crossover design was.. nor how that translated into off axis response

[@MyHalo777]

You are 100% correct! It was my thought exactly even before he spoke about opening the boxes. I was thinking, I bet he didnt break them in, and sure enough he then went on to talk about measuring them right after setup. Ill tell you a related story.... I purchased LRS from an authorized dealer. I absolutely loved them and got them dialed in with subs. They were my first Maggies and it was only a month or so before I decided I had to move up the line. I wanted to hear the .7s and the 1.7s. I called the dealer and they said they had .7s ready to go and had a brand new pair of 1.7s in the box they would setup. I said great and booked an appointment the next day. They rushed and setup the 1.7s as quickly as they could, but when I arrived they were still "breaking them in." I was quite shocked actually. They were using some audio track (not music) that absolutely punished the new 1.7s where you could hear the panels slapping as they reached max excursion. I would never have dared to push my Maggies that hard, but I found out this was their way to speed up the break in process. However, when I listed to the .7s and the 1.7s, the .7s were better than my dialed LRS. The 1.7s that only had a few hours of extreme break in sounded like absolute crap. THis made my decision really tough. On listening alone, the 1.7s were crap but the ..7s were not a huge jump over the LRS with subs. There was a Saleperson there who was super knowledgeable (he actually has a very popular audio youtube channel now) who I asked for advice. I had told him earlier the 1.7s sounded like crap and he totally agreed. I told him I am leaning towards purchasing the 1.7s just on faith and the assumption that they are the better speaker but need a longer break in. He didnt try to sway me either way, but he responded that in his opinion the 1.7 was the better speaker. I rolled the dice and went with the 1.7s (they ordered me a new pair and I used my LRS in the meantime.) When I finally received the 1.7s they were absolutely amazing, but did take a long break in. I cant remember how long but I think it was in the range of 100-200 hours. To this day, they are definitely my favorite pair of Magnepans. Long story short, designing a crossover on measurements taken before adequeate break in means they will sound like crap once they are broken in. Good Luck! I would never let anyone rip apart my brand new Maggies btw. Use them for a few months and see where they are at before ripping them apart. LOL

[@thenorfolkst]

He claims the electronics and drive units will need 200 hours of “ burn in “ before they sound how they should then proceeds to design a crossover for a speaker he says is only half burnt in and will sonically change . So how does he know the crossovers will then be correct ? Be careful there’s a lot of snake oil being sold

[@512bb]

I have had a soft spot for panel speakers since the early 80's, owned the Typani IVa's, 3.6 & 20.7's, the Maggie crossovers have always been a real shortcoming so I would highly recommend considering this crossover upgrade if you're serious about Maggie's. And if you really want to take it to the extreme, active bi-amping or tri-amping is magical when done right. Short of the extreme expense & complexity, this looks like a really nice piece at a very reasonable price, two thumbs up Danny.

[@randomtube8226]

I think more speaker manufacturers should make speakers with external crossovers. That way you can buy them with stock or upgraded crossovers. Without having to disassemble them to access the crossovers. Possibly damaging something in the process.

[@JoeJ-8282]

Yeah, that's especially true with more truly "high-end" speakers like these ones! (External crossovers aren't really any significant advantage on cheaper speakers, like most "entry level" ones under say $200-300 or so, however, external, (and therefore much easier upgradeable), crossovers available for or already designed for the higher-end brands and models of speakers, especially once you get into the $2000-$3000 and up price ranges, would be VERY beneficial, especially since buyers of high-end speakers are also more appreciative of designs that actually bring out the very BEST sound quality in whatever gear they invest in, especially their speakers, which are of course the MOST significant and important part of any audio system towards getting the very BEST sound that you can get out of said system.

Excellent video! Thanks from a former owner of the Maggie 20.0 & 20.1s.

[@ChrisJohnson-c3s]

I had Advent model 1, AR3a's, Polk Audio SDA. I still have KEF reference series, dynaudio special 25, I mix through ATC45a pro monitors and I own a pair of stock 3.7i's that I bought shortly before seeing this video. I love Danny's videos and I have no doubt that swapping out the Crossovers would make a big difference over the crappy parts and wires and connectors and magnetic stuff they have in there. I bought these speakers because I originally bought the lrs on a whim and fell in love with the sound. When I first got these I was wondering if I had made a mistake but after hours of playing everything opened up and I I am really happy with the speakers. I don't sense the overlap of the drivers when I listen to them. I would like to see Danny do this same process with mine now that they're broken in and measure those because my speakers sound nothing like they did when I received them. I wonder if Danny has done any 3.7i upgrades since this video? Picturing myself renting a van and driving my speakers down to Texas

[@jurgengrau1840]

As a long time Maggie owner and now owning 3.7i I would like to see them come from the factory with better stands and connectors( at least as an option). Lots of open baffle speakers now give the owner opportunity to play with crossovers using factory supplied upgraded parts. Many have external and quite accessible boards or boxes that are well marked to make changing XO parts easy and predictable. I really enjoy my Maggie’s but the company seems indifferent to the speaker’s shortcomings and requests by its dealers and customers in these regards. Thanks for the video and product Danny, hoping someone puts up a video showing more detail of the process.

[@Zenk61]

I found that Maggies sound best when you eliminate the speaker level XO all together and implement the XO at the line level. In this case you would be tri-amping. Phil Marchand (Marchand Electronics) will custom make you a Passive Line Level Crossover (PLLXO) with the specs you desire. I am running a set of Tympani 1D's this way and the results are amazing.

[@dannyrichie9743]

Unless he is setting up the speakers in front of a microphone and watching the measured responses as he designs then the crossovers then it will not work with this speaker or any other Magnepan model. The Magnepans are very unconventional and will not work with textbook slopes designed from electrical parameters.

[@Zenk61]

Danny… or anyone else for that matter, is welcome to come hear the results for yourself. I think you will find it is worth your time.

[@JoeJ-8282]

@@Zenk61 I kind of agree with what Danny said about these speakers, above, in that they ARE very unique and different than anything else on the market, therefore making them considerably more challenging to notably improve than your "typical", everyday dynamic speaker, however, since I have an open mind, (AND IF I was actually rich enough to afford these speakers in the first place, lol), I would really love to hear and compare the differences between the improved/redesigned passive crossover that Danny designed here, with one that Phil would design for these speakers in the line level, (along with top notch tri-amplification of course), (which is of course a considerably more expensive way to listen to these, or ANY speaker for that matter, but that is another topic entirely), but anyway, then comparing those two different methods of design improvement, to see which method actually improves the overall sound quality of these speakers the MOST, and then be able to go with that... I have heard some great things done with LL X-overs and bi or tri amping, IF it's implemented correctly, taking into consideration all of the individual driver's parameters and comfortable frequency response ranges, but that method is ALSO a very good way to totally screw up the sound from a speaker system and make it sound even worse than it did originally if it's done without any consideration of a speaker's driver's individual characteristics, so LL X-overs have to be implented properly or else they're NOT worth doing, especially considering that it ALSO costs WAY more in amplification doing it that way! Regardless, it looks like Danny's re-designed crossovers shown here are definitely a relatively inexpensive AND considerable improvement in these speakers. The overall value for the money invested is definitely there, you can't deny that!

Wow, this channel is amazing. I just watched your other video about comparing a $350 speaker to a $4,000 speaker. I can't believe the components in each speaker were worth less than $10 each!!! That is an outrage... But I have two principle comments I'd like to ask if I may. Firstly, you've probably addressed this elsewhere, but would it be possible to have a recording of some music with the speakers, with before and after comparisons? I know as audiophiles that might sound like sacrilege. But channels like Sound Sommelier (high end hi fi store in Italy) do it, and obviously not listening quality sound, you can hear there are a lot more details brought out with that level of equipment. You can hear how crossover levels etc. give so much better definition to the sound. Secondly is quite a bit more challenging. I would be interested to know about the more expensive gear, what's in them and are things like the B&W Nautilus speakers really worth $60k? Can you reproduce that sound quality on a cheaper speaker for less money (even if upgrades to those speakers might cost several thousand dollars)? Sorry for my ignorance if these are dumb questions. Thanks

[@dannyrichie9743]

We have been working on the recording before and after music from them. I think we have it down now. Uploading them to a KZbin file (compressed) just doesn't work out very well. They will have to be downloadable files that you can compare to really hear the differences. Some of those super expensive models step up the quality of the internals and some do not. More money doesn't mean higher quality all of the time, but sometimes it does.

[@stevengagnon4777]

See your questions weren't dumb. You got a considerate answer and gained some knowledge. Dumb would be not asking and destroying an expensive piece of equipment due to lack of knowledge. Thanks Danny.

[@stevengagnon4777]

​​@@dannyrichie9743that could be useful for someone who already owns and has been listening to the speakers for awhile...you already have an idea of what's off, hence considering an upgrade. You know what they sound like in room. Monitoring a recording before and after in a good set of headphones a person should be able to predict with reason what is going to change in room with the modifications. It's not like doing this for a review but any means. I thank you for answering the posters questions with consideration too. As I responded earlier to the poster....there aren't dumb questions and lack of knowledge is the dumb thing. In this speaker's case an outboard crossover seems pretty necessary as all they could fit inside was not adequate in the first place considering the expense of the drive elements. I can't imagine that the likes of the Budapest String Quartet or Andres Segovia with just his guitar ( know well what a classic guitar sounds like as I grew up listening daily to my sister learning to play one)would sound right even after a large burn in time.

Unfortunately, I think it's a given that recording music being played through some speakers and then posting it online doesn't provide half the experience actual listening in the room provides.

I am a photographer myself and since the advent of the digital age, I know that if you look at a 2mb image that's been taken with a 1 megapixel camera vs a 20 megapixel camera, the 2mb image from the 20 megapixel camera will still look miles better.

I wish manufacturers would take a video like this and say for the same price we'll wire the drivers to three different binding posts in a 2.5 or 3 way design and you may use Danny's crossovers. A 4 way would be 4 binding posts, etc... Then all crossovers could be external.

[@JoeJ-8282]

So, making an $8000 speaker ~$9100 instead, but making them sound and perform at least twice as good, probably even more, I would say is VERY well worth it, because if you can already afford to invest in these speakers, then spending just over 10% more to make them actually sound as awesome and amazing as you're initially thinking they're going to, is definitely a step I would take with these, IF I could actually afford them in the first place! Danny, with how much better they perform and sound with your newly designed crossovers for these, (and for (relatively) not too much more than they already cost either), I wouldn't be surprised if Magnepan actually collabs with and pays you to make these crossovers a permanent design change for these speakers from the factory when bought new, straight out of the box! (At least they should seriously consider doing something like that with you if they really want these speakers to be the absolute BEST that they can be!)

Although everyone seems to be very tight-lipped about the differences between the 3.7 and 3.7i, I have a sneaking suspicion that the difference between the two is in the crossover, and the panels are identical - which would mean that your crossover would probably be even more of an improvement in the 3.7 than the 3.7i. In your conversations with Magnepan, have you learned anything that would make you think that the crossover would work in both models?

[@biko331966]

I have a smaller 2 way mg model, and I removed the entire xover, added 2 amps and an electronic crossover to do the job. Mgs' xover comes with a little hole in the mids (a little bit recessed) and an inflated bass to seem that it has more bass than they have.

Thank you for your insights into peformance characteristics of Magnapan speakers, and big panel speakers in general. Priceless. It's now crystal clear why those big panels never image with pin point specificity, and what their inherent limitations are.

[@glennbehrens9314]

....never image with pinpoint accuracy....? Such a broad statement in narrow in thinking. I beg to differ, I've got no problem pinpointing the vocalist from the violin from the drum set, etc., etc. As with any speaker, take the time for proper placement and some easy room enhancements and you'll get the "pin point" placement you want. My 3.7i's are proof - in my room / setup anyway.

[@gmp203]

It’s always been pretty much acknowledged that the Maggies excel in the drivers but the crossover and wiring connections have always been a bit suspect. I wish you would get together with magna pan and develop an upgrade with your external crossover and magnepan providing the input connectors on the back of the speaker as you describe without any internal crossover. It would be great to be able to buy the entire package from one vendor. In any event well done and much appreciated

You know what engineers say about fuse selection. Always select your components to protect the fuse. And at that price point, it might be worth building the worlds most complex crossover. You know, one to three notch filters on each driver to tame those peaks. /jk Great work on that off axis response. That is true magic right there.

Even when doing gated its best to drag panels outside due to how the rearwave affects the measured response ..!

Any rear wave output is gated away and not present in the measure responses.

[@billmilosz]

Well now I have a DEQX Pre-8 and the advanced algorithm resulted in a better sound, and in particular it integrated my GRS servo open baffle subwoofers better. One gets very accurate results and with the steep linear phase crossovers between bass panel and midrange "stripe" you get better imaging- midrange is no longer coming from that big bass radiator. Also, there's no crossover parts between my power amps and the panels, power delivery and damping is better.

[@aussie_philosopher8079]

That's a lot of work done there.

These were on my list but the idea of negotiating with Magnepan on such a major redesign pretty much kills my interest. I really appreciate the video for illuminating the situation.

They do sound great with the original XO's, so I'd keep that in mind. If you want to upgrade them that's great, but it doesn't mean that the speakers sound bad to begin with -- stock, they pretty much trounce anything in their price range on acoustical music.

Much better than the original but not perfect yet. to get it perfect, you probably need up to 15 filter parts. on my 2 way, I had to use 12 parts in total! if I had spent so much time sending a speaker, I would have demanded a little better

[@jordanmetcalfe8302]

It would be interesting to measure a set of Apogee Acoustics speakers of similar size (Duetta Signature or Diva) and see how they compare. Having compared the two in listening tests, I can understand why Magnepan were afraid enough to decide to sue them practically into the ground.

[@jacksound5471]

[@jurgengrau1840]

For some interesting comments on x over design there is some insight presented on the cheap audio man’s interview around the design of the new source point 10 Mofi. Thoughts around flat response and which dips and rises in response might be desirable. Not meant as a comment on what Danny is doing but further insight by a designer.

[@hugobloemers4425]

I can not imagine Magnepan giving warranty on this mod, if done by the consumer. What is needed, is a collaboration between Megnepan and GR research. Also, the way the crossover connects to the three drivers, leaves too much room to connect the woofer-out signal to the tweeter. At the very least you should have six different colors of tube connectors and wiring, to make it a bit more idiot proof and contemplate warranty. Other than that, this is a great upgrade. Is the $1100,- for one or two speakers? And do you get the cross over enclosure with it?

[@davestevens4193]

Well done. Can the new crossover bi amp?

[@dannyrichie9743]

It could, but the way to do it and get the most gain isn't to divide the panel up into different amps. It would be to filter the lows off of it and send the bottom end to some servo subs.

[@torstenschiemenz7602]

Hi, first of all, very interesting and very well done. However, I have to admit that I have been owning Maggies since early 90th, current model is a 3.7. They were a nice upgrade to the my >20 year old 3.3r. Anyway, what I was a bit surprised about whas the frequency response you showed. I did that all myself at my seating position and at least here my 3.7 si quite linear, starting at 30Hz up to over 20MHz, falling slowy over from 30Hz-20KHz of about 5-7db. There is only a very slight peek around 500Hz, IMO just some room resonance. Only modification I did on that older version of the 3.7 is to have new "feet" attached. The amp is a JR625 ;-) and yes, they need power. Regarding the fuses I can only admit that they already saved my Maggies lives as by the time they were attached to a JR Continuum and my boy simply turned volume to max the fuses blew away... Guess distortions where just to high - whatever. With the 625 at highest output there is no such flaws - anyway. Coming back to my point. Guess it would be good if you could attach some pictures on how you measured the speakers. From my end I would say that to near is not a good idea but I would also not have a much different approach in mind. I am used to measuring mine always in room and at listening position..... Thanks again for putting such efforts in measuring and tweaking.... Greatings from Germany, Torsten

[@dannyrichie9743]

Thanks for watching. I measured them from various distances to see what the differences were. Not only was the original response a problem but the parts quality (lack there of) was also a problem.

[@spudpud-T67]

Danny's measurements may be picking up the fact the new speakers had not yet been broken in. Sure the components are not premium quality as it's built to a price. But those would be the same components as in your panels. Perhaps that shows you the importance of breakin and room placement are having a greater impact on measurement than components.

[@Pksparty2112]

They say you need to get Maggie’s in the exact right place to sound right and it takes a lot of work. Now it starting to make sense why.

Of axis Much better !! good job. i really have no clue why they try to let them play all together. they need to use the drivers for what they are made for bass is for bass mid for mid tweet for top end. and yes that means more expensive and complicated crossover, else the bass is not gone yet before the mids plays along and the mid not gone before the tweeter starts.. its just dumb

[@hifitommy]

the $1100 cost for the new xovers may sound like a lot of money unless it's expressed as a percentage of the new price of the speakers. the suggestion of approaching the factory to save the effort and physical integrity of the speakers, eliminating the need to de-staple and re-staple the grill cloths to allow the external xover box is the intelligent approach. a cooperative venture to improve all of Magnepan's speakers would be a considerartion for Magnepan, profitable for both companies. ...hifitommy

[@jwester7009]

Since the mid-range panel plays up to 10kHz I can't help wonder how it would work if you let it play to almost that high and then use the tweeter as an ultra high frequency driver. It's just an idea but maybe you didn't have to use the notch filter at 7kHz then?

[@dannyrichie9743]

Then as soon as you move left or right the time arrival differences cancel out the response.

[@batterytestchannel-v4v]

Danny, I am going to get the Maggie 1.7i. Have you already done a mod for that? If not, would it be better fir me to send them to you after I’ve played them in, or direct from the factory?

An upgrade for that model is available on our website.

[@itchylois]

If these came straight from the manufacturer, they had no break in period. I wonder what the measurements would have been if the Maggies were played for a couple hundred hours.

I was mistaken. The customer had these for a while, and they were burned in. The way he re-boxed and packed them it looked like they just left the factory.

We had one of them sent in. They did measure poorly, but it was nearly impossible to remove the drivers to work on them. So there was no way of making a simple upgrade that the customers could implement.

[@JessicaSiemens]

Hi Danny. How did you account for the reflections coming from the rear of the speaker? If they were not placed the correct distance from the wall, throwing the timing off for the sound coming from the rear of the speaker, this could have accounted for your measurements. Placed in a regular room setting, they may not work as well after these changes. Did you account for all of these factors? Thank you for the video.

[@dannyrichie9743]

I use a gated time window for the measurements. So there is no rear wave or wall reflections in the measurements.

[@hlurpseed]

Has Danny done a show on why steel parts are so awful in the signal path?

[@Shawn-wy1pb]

All steel parts hold residual charges and become magnetic once electricity passes through them and this degrades and muffles the sound.

[@joppepeelen]

The rize down low, is because it is measured to close :( + the typical 500Hz Hump on all maggies. because the drivers are crossed to high. since it is open baffle IT need to ryze under 300hz when measured up close. at distance it will lose that rise. the crossover work on those is pretty bad. i dont know if they ever calculate the wavelength to see where it should be crossed at least. like.... that mid should cover 300-400hz and up crossed low enough again to the tweeter. now why they did not ? my guess output. this way you have most output and most simple filter. since the bass panel has a rising response you should cross them really low so acoustically it will end up much higher. this means huge coils.. or multiple coils and caps if steeper filter was used. lets not forget there is not much room for multiple coils and caps to get the filter that they deserved. when measured so close it should roll off from down to high freq. so a weird slope, but if you measured it after at 2 meter. it would be almost flat

[@dannyrichie9743]

I measured them at various distances to confirm the response.

[@stuartnorman8713]

Tell us what happens in a crossover network as it burns in.

[@hifi2169]

Ok, at first the bass was very punchy, then, as bass started to smooth out, the mid range was very pronounced Vocals seem to be the main attraction. Now that the crossovers are more than likely 100% burned in, (it always takes longer than you think)everything has really smoothed out. -Done.
