Awesome review. Exactly what I want to see from a reviewer. I don't care about fancy living rooms and opinions. I want to see exactly what you showed. Great job.
Hi ! To answer your question about the bucking magnet : It is use to concentrate the magnetic field inside the gap where the voice coil is moving. To shield a driver, a steel 'pot' or cover is often use to further isolate the magnetic field.
"A bucking magnet is a magnet placed near another magnet with opposing polarity to cancel out its magnetic field. This technique is commonly used in various applications to minimise unwanted magnetic interference or to create a more stable magnetic field." Source below: engineeryoursound.com/what-is-a-bucking-magnet-speaker-design-explained/
If I follow your reasoning, it would mean there would be no magnetic field to make the voice coil move. You can see that it makes no sense. Furthermore, if you put something ferromagnetic close to the magnet, you will see that the magnetic field is still quite strong and extend several inches from the driver.@@generationbehindhifi
@@yvesboutin5604 It's not my reasoning! Just about every publication has said the same thing regarding bucking magnets. I think you might be overthinking this a bit. Bucking magnets cancel out the external magnetic field of the main speaker's magnet so it has little effect on how a tube TV operates. I wasn't planning on going in depth behind the engineering of bucking magnets in this video. I just wanted to share what they were primarily used for back in the 80s and 90s, and that they were somewhat rare to see now a days. If you would like to know more, then I would suggest looking at the video that Audioholics did on the Heco Aurora 1000. They touched on bucking magnets in their review and basically said the same thing I did. Hope this helps!
I listened to the video and it didn't confirm or deny the point in contention. It would be better if you get technical informations for an electrical engineer book than a conversation between two persons on a Utube channel. I modified a pair of speakers for a young man who wanted his two little speakers sitting right on top of his parents old TV with a couple of cans of tuna. Another time, a tiny tranfo was so close to the TV tube that it was distorting the image on screen. This time I used aluminium plating to shield the coils without interfering in the performance of the transfo. Copper can also be used in conjonction with other metals to contain electromagnetic interference like radio signals. And as I said earlier, if you would do the test for yourself, you would see that a bucking magnet do not prevent magnetic field to expand beyound the driver. @@generationbehindhifi
I got mine at Audio Advice in Raleigh they sold me the floor models for 489 a pair. Last week I was able to buy the 30a subwoofer for 229, normally 489.
That's a lot of speaker for $489 a pair! I also recently purchased the 30A subwoofer at $229 and its ok -- Look inside video coming soon. I definitely like the speakers much better than the subwoofer. The main problem with the subwoofer is bandwidth. During the opening scene in Tenet there is a very heavy low frequency bass track and the Aurora 30A can't reproduce those low notes too well. At first I thought the subwoofer was turned off and it wasn't. After some research I noticed that Audioholics did a review and mentioned that his subwoofer falls of a cliff below 40Hz! No wonder I couldn't hear that low frequency track on Tenet! At $229 I think it offers pretty decent value, but it does have its limitations. IMO the Aurora 300, 700, and 1000 are the real bargains in the line up. They really are fantastic speakers for their price point!
Looks like the people at Heco care about what they are sending out the door. Great to see such high quality measures in a budget speaker. Thanks for these detailed tear down videos I enjoy geeking out over this stuff more than the actual reviews. 👍🏻
For sure! Heco has done a really nice job with this speaker and the best part is, it's very affordable! Also, keep the shots of the Aurora drivers in your memory because another speaker company (Cerwin-Vega) uses an identical driver design in their new LA series of speakers.
Thanks for another build video. Very informative. Saw a good sound review of them online and your positive feedback has me looking forward to your upcoming sound review. You didn’t have to say the $2,200 build competitor so I will - Focal. Keep up the good work!
I just discovered that the Dayton Reference tweeter has the same size flange and hole pattern as the tweeter in these Aurora series speakers. Probably some of the other Heco speakers as well. I ordered a pair and plan to swap them out to see how it works. Should be interesting. I’ll do some measurements to see if the sensitivity matches up. The Heco tweeter is nice but the Dayton Reference is pretty a really high quality unit.
Cool! Thanks for sharing. Can you share the model number? Another one that is a drop in fit (will need to drill a few more screw holes) is the Peerless DX25BG60-04.
@ The part number is RST28F-4. While it fits into the hole perfectly and the holes line up, the solid aluminum flange on the Dayton tweeter is thinner by about an 1/8 of an inch than the stock Heco tweeter. I will resolve that by coming back with some flexible solid caulking stuff that I have. Hopefully that works. This Dayton tweeter seems a bit more sensitive than the Heco. I can’t tell you exactly how it will interact with the stock Heco crossover because I converted my speakers to active with mini DSP. I need to resolve that recess though before I know for sure because that is surely creating some diffraction issues. I would imaging that if you are using an AVR or anything with room correction or even a PEQ, you could dial in the frequency response.
I think GR research just did a review of this speaker They were very impressed with the flat frequency response There was a hump at 600 hz and they had an inexpensive upgrade for it Also the speaker could use some additional bracing
I honestly can't think of a better floor standing speaker for the money. A pair of Aurora 700's are less than $1k shipped to your door and have incredible sound and build quality for this price point. I'm surprised that these speakers are not more popular because you do get quite a bit of performance for your dollar.
The vents on the midrange driver are mainly there to reduce the "spring" of trapped air, behind the dust cover, and behind the spider. Your impedance sweep looks to have 3 or 4 significant resonances? (Which are indicated by the "blips"/ripples in the impedance - at ~750Hx, just under 2kHz is a big one, and just above 5kHz.)
Yep, I saw that too. The resonances are not from the cabinet because I'm measuring the driver in an open baffle. IMO the vented pole piece is there to release the pressure from the trapped air behind the dust cap (but can also be used to cool the VC indirectly) and the vents under the spider are primarily there for cooling the voice coil.

Great video 🙂, could you please tell me what is Heco tweeter resistance?, I have seen you have replaced them with 4Ohms Peerless, in my case I have decided to put SEAS PRESTIGE H 0831-06 ( 27TFF ), Wonder if there is a big difference between them
Hello Daniel! Thanks! In this video I have the impedance sweep of the factory tweeter at around the 6:00 minute mark. DC resistance came in at 3.2 ohms (4ohms). I'm not familiar with the tweeter you picked up, but did see that its 6 ohms. Because of this you will need to do some crossover tuning.

@@danielilnicki9324Sorry, so did you just exchange the tweeter? Where did you buy it? I like the sound Hecos signature but it sounds like fun what you did.
@@danielilnicki9324 I tested both tweeters and the Scan Speak sounds even better than the SEAS 6ohm ones... The Scan Speak are more detailed without being obtrusive. I listened then for 2 days: original heco, SEAS prestige and scan Speak and I stayed with scan Speak due to much better detail and separation of sounds. The speakers have become a little brighter than the factory ones, but it's not as bright as in the focal aria speakers, but the detail does the job :) If someone would consider that tweeter is to load, without replacing the crossover, you can lower the volume without changing the resistance (lpad) . For example - 2dB
@@maciekczlCan you provide me with more specific details about the Scan Speak speakers pls? Or send me a link where I can buy them, I assume all demensions remain the same?
If you follow the magnet field of the extra magnet and through the plate on rear of motor magnet it cant add to motor magnet. The most likely purpose is for shielding, but as you said why. The other possibility is its just to add mass . To prevent speaker frame from moving in opposite direction to cone. Think of a gun the only reason the person in front of gun gets shot and not the person holding the gun is due to guns mass. If gun and bullet had equal mass both people would get shot.
I do not think they are even all iron core inductors , From the shape they look like it , but if they are like the aurora 1000 , only one is a iron core inductors , despite the shape and aspect of the rest , I do think they are air core inductors
@@generationbehindhifi thank you for making speaker video reviews, its ez to find good decent speakers with your budget is $$$$ but its hard to find a good sounding speaker with a $$$ budget. Ideally you want to go and listen to speakers but not everyone lives near a store were ppl can compare A to B speaker and not everyone whats to purchase anything on a lower budgets. But i do appreciate when reviewers take to time to review a non well known brand along with a honest review with views on the internals, to see what you get for the money, where they might have cut back costs etc.
IEEE did a white paper on ferromagnetic parts in audio connectors and its a good read. Basically the study proved that ferromagnetic parts introduce passive intermodulation, aka 3rd-order harmonics distortion to the signal! Simply put, there's a reason why high end speakers use non ferromagnetic parts in the signal path. Paper can be read here: ieeexplore.ieee.org/ielaam/22/8681220/8632973-aam.pdf
I don’t think the ferromagnetic nuts make a difference. After all, you could use completely non-conductive nuts and they would make no difference as long as the threaded rods and tabs aren’t steel. After all, the signal bypasses the nuts through the rods and tabs. Sure, I’d feel better if they were brass or copper, but that’s just palliative.

Think of a gun the only reason the person in front of gun gets shot and not the person holding the gun is due to guns mass. If gun and bullet had equal mass both people would get shot.
I wonder how they sound against RP 800f 2. Similar build and price on sale
The heco 700 are 400€ less then the Klipsch RP 800f2
I do not think they are even all iron core inductors ,
From the shape they look like it , but if they are like the aurora 1000 , only one is a iron core inductors , despite the shape and aspect of the rest , I do think they are air core inductors
Somebody has been watching GR Research. ;)
nice
HECO mereged with Magnat and also isolates the mid-range woofer
Thanks for sharing that information. I had no idea Heco and Magnat were under the same umbrella, but I'm also pretty new to the brand.
@@generationbehindhifi thank you for making speaker video reviews, its ez to find good decent speakers with your budget is $$$$ but its hard to find a good sounding speaker with a $$$ budget. Ideally you want to go and listen to speakers but not everyone lives near a store were ppl can compare A to B speaker and not everyone whats to purchase anything on a lower budgets. But i do appreciate when reviewers take to time to review a non well known brand along with a honest review with views on the internals, to see what you get for the money, where they might have cut back costs etc.
There is actually only 1 iron core inductor, the other 3 are air core.
Someone has been watching GR research. He did the Aurora 1000. I have the 700 so they are a different model.
Why whould steel nuts affect sound?
IEEE did a white paper on ferromagnetic parts in audio connectors and its a good read. Basically the study proved that ferromagnetic parts introduce passive intermodulation, aka 3rd-order harmonics distortion to the signal! Simply put, there's a reason why high end speakers use non ferromagnetic parts in the signal path.

@@generationbehindhifi Thanks for your explaination. I will certainly have a read of the white paper. Cheers Ian.
Try to buy PYLON speakers from Poland and they will blow Your mind 😊
fluctus in Latin means wave.
Thanks for sharing.
I don’t think the ferromagnetic nuts make a difference. After all, you could use completely non-conductive nuts and they would make no difference as long as the threaded rods and tabs aren’t steel. After all, the signal bypasses the nuts through the rods and tabs. Sure, I’d feel better if they were brass or copper, but that’s just palliative.
