That hole for the tweeter is for air to escape. Likely pressure and cooling If they wanted it sealed, it would be sealed.

I am waiting for my ns-777's to arrive. I don't want the feet sticking out as well. I am hoping to mount them inwards instead of outwards. I also ordered yamaha powered subwoofer so no need to get into the guts. Thanks for sharing, definitely worth a like.

Congratulations! You started on the same path I did 30 years ago and learned a few things along the way! If I may give you an advice, if you want to rework the crossover with better parts (air core inductors and Mylar capacitors) you would discover that the midrange and tweeter sound will improve. Also, Polyfill is not always the best material for damping speakers. Some acoustic foam around 12 millimeters thick could provide a better performance. To check if that works well, modify one speaker at a time and do a A-B comparison using a monophonic recording or pink noise. It will cost you more than a few dollars, but the reward could be amazing!

@@rickcorel5154 I'm not sure if it will work because it hardens and its acoustical property are almost the same as wood or metal. Whatever you use must be 'spongy' or fibrous in nature for sound waves to be absorb and not radiate back in the enclosure. Foam of polyfill are the most used but you may try other products with sound proofing properties. Good luck!

I bought my 2 NS-777 on craigslist 9 years ago for like $150. Great speakers. The only thing, sun was on one of the speakers and laminate shrunk/distorted and came off on a side.

From all yamaha floor speakers can to say NS-F160 its clear sound plus good strong and clear bass,and inside can to say its empty none any foams,some made just to look nice and crazy prise,still pay for name,good luck👍🏼

I just bought some nsf160 towers second hand, and they have foam in them down the bottom half in the middle. do yours have foam in them at all? from factory?

All right I said before that I will do the similar polyfill coating of the inside. And I did. Not as same as told in the you tube video.I cut the polyfill pieces much more bigger, I used much more polyfill and covered much more inside area. I also used the sponges already yamaha put. I covered the crossover circuit too. I put so much sguuezed polyfill in the medium driver's case. I didn't make anything to the tweeters. Ok. The basses became deeper as it comes from the back, you feel much more bass in your abdomenal innards. Much more improvement achieved in the mids. Mids became more clearer, less distortion. Thanks to the polyfill, thanks to my workmanship and struggle shame to the lazy Yamaha!

Super Useful Information

Эти колонки как ни улучшай, хорошего звука не дождёшься.

Polyfill adhered to the insides has no effect on standing waves, since that's where the pressure is highest but the speed of air approaches zero. For damping the actual enclosure panel's modes you need heavy mats, not a sponge. Enclosure panels look flimsy, so if you put your ear against it you will realize that actually the box emits as much sound as the speaker itself, which is not synonymous with HiFi. As the diaphragm moves, the box wants to move in the opposite direction, cannon and shell principle.That's why you want to anchor the speakers on spikes - to make it impossible for it to move. Spray the bead or your finger with window cleaner - it won't stick and you'll have a smooth joint, that you didn't really need in the first place. Why ? Because they are ported, hence the air follows the path of least resistance and flows through the resonator, well, below and above the tuning frequency, but that's beyond the scope of a short comment. In simple terms, no air will be forced through tiny gaps as it flows through the port easily. This also explains why they didn't bother to seal the back of the tweeter, although an airtight cup would normally be there with the detriment of increasing tweeter fundamental (Cms x Mms) resonance frequency. Crossover looks dirt cheap, and so does the speaker actually, lack of low frequency extension is a function of efficiency, they were made to play loud, not deep, end of.

@@CT-vl3iu NS777's weight is listed as 24kG each, which considering its size can hardly be described as heavy, rather standard. Not sure what you mean by base, but in terms of low frequency extension, or bass, there is a trade-off between LFE extension and efficiency inherent in every design, with balance tipped towards level rather than extension here. Adding a subwoofer to compensate for poor performance of main speakers in other areas seems bizarre to be honest.

@@CT-vl3iu Absolutely, I have added a sub as well to my speakers; two Peerless XLS10 drivers in push pull configuration firing into a 20L sealed enclosure with a dedicated, seaparately housed amplifier. It's terribly overdamped with the Qtc of 0.35 thus falling into the range of infinite baffle rather than classical acoustic suspension arrangement. Fc is around 35Hz and the frequency response has a -3dB point at around 90Hz. I've accomodated a low q compensation network tuned to 22Hz to linearize it and ended up with a flat -3dB curve between 15 and 45Hz. The rest of the low frequency range is covered by the speakers however with two differentialy tuned 6" woofers in individual sealed enclosures. The efficiency as a whole is only around 83dB/1W/1m, but that's the price for having a flat response with such an arrangement.

Very good. I will attempt this myself with my NS-555's. There is indeed a lack of low end. Hopefully the poly-fill will result in sound production as if the enclosure were larger in size.

@@robertomanodepiedranomas4283 Both NS555 and NS777 would sound pretty similar. In terms of internals, the 555 and 777 are pretty much the same apart from the woofer size and minor crossover tweaks. Since I haven't owned the NS777, I couldn't tell you. My best assumption is they'd still sound pretty similar and lack low bass like many NS series Yamaha speakers. NS-SW300 is a great subwoofer and I think it will complement your speakers perfectly regardless if you choose 555 or 777. If size matters, I'd go NS555 since the 777's are quite big speakers. Since the speakers will only be handling the midbass - high frequency range, the NS555 would be fine since you are using a subwoofer to produce the lows.

Good job 👍...

The question would be is it worth it with the sub? I have an active sub and also have bi amped the front. I have four of the same spekers back and front. Could you give me advice?

Best part is: 11:00 :-D These YAMIS deserve much much more, since they are too bright sounding with those Nippon elcos on the crossovers at all, so change them with any type of MKPs, and listen! Note however, that the internal Monster brand cabling is good enough, just the box needs a little more reinforcements in the bass section, with some horizontal bracings, and they can be quite musical speakers at the end of the day for sure!

Interesting, I just uploaded a video where I found 2 boxes of ns-333's at the dump. I might be getting a set of these speakers at some stage to complement them. But I already have subs so probably won't do the change. Interesting to watch though 👍

Tip to save the time, all of this is wonderful, but the key is just removing the two pieces of dark grey foam - one in each. Accessible from just temporarily removing the bottom woofer, removes damping and gives more bass, it was this which contributed to the improvement in low end response.

I just got some of these second hand for a steal! They sound pretty good but they show up that my class D amplifier isn't the best for driving such speakers. I think they will sound much fuller with a decent amp when I can afford one. Sound ok though, just sound a little dull with the current amp (Aiyima A07). I'm thinking of getting a second Aiyima and running my old speakers just to crisp things up a bit.

I just bought these speakers I thing they sound Great the bass is large maybe a bit boomy depending on what's played. my opion and experience not saying I'm correct ,why wouldn't Yamaha not seal there speakers on the corners, if they leaked air you would feel the air escaping from the corners when turned up loud if you can't feel air escaping I dont see the point putting filler in all the corners maybe for re enforcement that's about it.A good test seal the port with a tennis ball and turn it up and see if you feel air escaping if you don't then the box is sealed. I know a leaking box does affect the sound ported or sealed, sealing it makes a big difference from my experience with building subwoofer boxes for cars.adding more material to the midrange I believe your changing the volume of air it was intended for and adding all the insulation inside changes the acoustics of the speaker and will alter the sound .I think maybe better quality backing might help like closed cell foam behind the speakers alone . Just my opinion but I guess ears will tell the end result.

My viewer sent me such speakers for an upgrade. I'll be in my studio literally in a week. I will definitely upload the video to my channel. I will also make a kit for selling a new filter. I invite everyone who has such speakers !!!

тоже тмею такой комплект ) вот тоже бы надо заняться доработками)

And at the metal reception I came across a box from 1 satellite from NS-333 only without a large speaker only High-frequency

The reason why there's only so little amount of acoustic damping is they possibly wanted it that way. And the sealant on that opening at the back of the tweeter will not be good for air circulation and possibly damage the tweeter because of overheating etc. Let professionals do the job. May be more costly, but trial and error can be too.

Well. If you want something done right, you gotta do it your self.

Why not, polyfill can prevent mid and treble coming out of the port and reflect on the wall behind the speakers. Resonance frequency may be increased a bit so it will produce louder bass (at the cost of less bass extension). These speakers extend to 30Hz by specs and most music do not have frequencies around 30Hz anyway.

These are ported and as so do not need filled everywhere with foam filler, in fact you just detuned your speakers, you want the air to move around in a ported enclosure, I wasn't aware these speakers were ported until mine arrived today, I have them hooked up to a Kenwood KA-80 Stereo amp and the bass is beautiful, I think you just have a cheap Amplifier or poor hearing 🤷

Mister, isolate the upper section from the bass section. Get rid of the midrange woofer from the cap. And make the back of the wall of the upper compartment open, let the midrange speaker be in the open air. Install a rectangular plastic grille on top of the case so that it hides the hole.
