За неправильный подход к акустике. Оно и слышно как пердит а не играет. Неправильно ВСЁ! От пищащей щели перед динамиком до пердячего ящика без рёбер жёсткости и звукоизоляции. Хотя динамик восстановили классно.
Сам в шоке 😲! Пердозвук а не "низы"👎. Свой "саб" когда впервые тестировал все наровил вывернуть так чтобы выделить "буханье" - результат полное искажение звучания трека. Звук должен мягко заполнять пространство (комнаты, зала) тем самым "дорисовывая" панораму звука.🎧🎼
Было смешно уже на этапе склейки и фиксации скобами или гвоздями, но результат значительно превзошёл все мои ожидания. Рассчитывал услышать в басе значительные призвуки от просачивания воздуха через щели, но у него вовсе получилось призвуками начисто замаскировать основной звук 🤣.

Watching this video just makes me want to buy some new in the box JBL's. It also reminds me how Peavey use to have replacement baskets with the cone already mounted, cool system.
With the knowledge he has to be able to do what he just did, how could he possibly not know that the parts need to be secured? He very likely didn't show that part because he believed the viewers were intelligent enough to figure that out. Yes. Absolutely.
With the not fixed components, this technician is assuring that his customer will return a few months after the warranty void... This is a continuous business plan, buddy 😅😂
No isolation, the circuit boards just random lose inside the box? They shortcut at some point of the movement and rattle. Nice work, but in many ways not good enough...
Attaching the board actually causes MORE vibration because it's then firmly attached to the vibrating surface of the enclosure. Either use rubber anti-vibration mounts or let it free float. Both methods are equally viable.
This is the greatest video I’ve ever seen. I am a sub god from way back….. and I approve this video. 🎉❤ And the building is rattling…..not the sub. I had a car that rattled apart with 4 fosgate 18” pro subs….
Amazing job. I just love it when you can recycle things like that. Many things could be restored and sold cheaper for people that can't afford more expensive things. I noticed lots of waste here at the recycling centers.
A lot of my repairs are like this. It's the easiest way to go about it when only the cone is damaged. Solvent doesn't have to be used and is faster with right tools and technique. But well executed.
Not something I need to watch, but something I enjoyed to watch nonetheless. Thanks for the upload. Pretty cool stuff. If only I knew those center cones could be replaced separately back in the 90’s. I purchased a lot of JL Audio subs with collapsed cones for cheap. An eyesore, but worked to spec otherwise.
he did secure all the interior he just didn't show it. while i agree mdf is a better airtight box that plywood works well enough to not be a major issue.
Plywood is layers of wood held together with glue. There are imperfections in the wood & in the gluing process that cause distortions in the sound. Those imperfections are not present in MDF.

For the laymen like who is looking to restore a couple of subs. Would you mind sharing the various glues and liquids and their purpose? Thank You. Also I saw where you restoring a JBL subwoofers electrical components, where did you get the electrical components from and that soldering tool? Thanks again.
It's nice. You built a very nice subwoofer box for that. If someone reads this I want to say the best 18" Pro Audio PA subwoofers for the price are Rockville Audio and Dayton audio and a few others. I have had an 18" $175 CT Sounds Tropo and did some TH-cam vids in my bedroom of it on a Hifonics BRX2000.1D amplifier and it also sounds amazing.

Hello there! Awesome video! I was wondering if you have repaired 6x9 speakers? I have two of these speakers but finding repair kits are very scarce. The rubber gasket on both speakers are damaged beyond repair. I wonder if you know how much the full repair kit would cost?
First time I’ve seen anyone else actually repair a speaker. back in my teens and early 20s. I used to get a lot of 6 x 9“ car speakers, and a few home speakers that didn’t work. Usually the car speakers had cones that were split all along the outer edge which made them rattle. One trick I would use is to simply cut out the damaged part, Take a vinyl tablecloth with the cotton/fuzz backing. Cut a donut out and glue it to the speaker cone/frame with model glue. I had one set that had been sitting in a vehicle in a salvage yard for years and after I repaired them, they were perfectly fine for several more years. The other thing was where the wires for the coil come out in attached to the cone. The black epoxy glue would become brittle and crack, snapping the wire in two. Those were usually fun to try to repair.

transistor will operate in high temprature without any ventilation ,at high levels which leads to distortion and destruction also affects transformers secondary winding.....
that clear plastic you put on the back of those transistors are really good at blocking electricity and heat. you should have isolated the back of the board if you were worried about shorts.
That's likely mica insulators as the back plane of the transistor is at the collector/drain's voltage/potential and must be isolated from the heat sink.

Maybe add some silicone at the joints to seal the cabinet better
I am impressed by the minimal tear-out in cutting and routing the plywood. Pity about the raw edges and glue smears.
Working with what you had & probably on a small budget, I think you did a pretty good job. If it does the job that you built it for, then that's ok.
