This is part 2 of my high end Gabster GS11 speakers where I show the detailed construction journey.
I constructed my best DIY high end Speakers using multiple constrained layer damping to build a woofer enclosure that is far superior, a audio muffler design for the midrange and unique dipole multi position tweeter. The speakers have a unique vintage but modern design and can be converted in a compact version with amazing sound.
Please subscribe with notifications so you do not miss any of my future Videos and to help support the channel.
For those looking for some plans you can find the Schematics, crossover design and drivers used in my Crossover Build Video part 1 at 7:00
The woofer enclosure is 2ft deep by 22inces wide by 22inches high
Midrange enclosure 9 inches widest diameter 7inches mid diameter by 22 inches
There is a possibility to adj both the Mid and Highs by + or - 3db based on the Rall tweeters position also your room and taste and some Adj with the Rall foams.

@sudd3660 Год назад

when you enjoy hifi the ultimate expression of that is make some yourself :) you really made some of the best cabinet, it was a joy to watch the process. i did make some myself recently, and i had to use active crossover because i do not have a clue about passive. also had a problem with hiss noise so i sold the plate amp but still have the speakers. i also made it a 3 way, but the 2 way part was separate and the bottom was like 2 stereo subwoofers. and compared to yours the cabinet is simple stuff, mdf wood with rubber layer on the inside. all by boxes was sealed so i filled it with some shredded fabric material made for the use, its pretty heavy compared to most other loose stuff normally sold.

@ferdinandbardamu3945 Год назад

Questions: 1. What crossover points did you settle on? Did you match directivity between mid and tweet or did you let the mid go as high as possible to avoid crossover in the vocal range? Comments: 2. I would have copied B&W matrix bracing technique for the midbass enclosure. 3. It doesn't look like you followed the B&W marlan head enclosure shape for the front of the midrange enclosure. I would have. Suggestion: 5. I you still can, line the enclosure walls with hawaphon steel pellet mats. Especially the midrange enclosure.

@sloapac3348 2 года назад

A superb work, real art. I am interested in how such linearity is possible in the external measurement of speakers between 20hz and 40hz, where these values are usually around -6db. Is it possible to display measurements at a greater distance in the room at the listening position by capturing the L and R speakers together.

@Gabster1 2 года назад

The measurement at 21:47 inside are way higher but not very linear mostly the port adds up better inside then outside. Since the port it is down firing it is hard to do a accurate measurement outside It is a lot easier measuring a front firing port as it would be in line with the drivers The curve I was aiming for inside is a bit higher in the low frequency and a bit in the high as flat can be boring Measurements change a lot as you move large speakers around inside or change the mic position outside at the end if they are for your own use in a fixed room best to do the final balance at the listening position.

@alexandercyborg5308 2 года назад

If the woofer crossover point is low enough and the wave length is bigger from the size box, then the shape of the box or the acoustic damper inside really doesn't matter.. Cause there is no standing wave. There are a lot of subwoofers without insulation inside with just an ordinary cube box..

isnt aluminum cabinet (or steel) more stiff? add to that aperiodic cabinet with stuffed large vent like in Zellaton flagship models or ME Geithain and you should in theory get more quality bass. What do you think?

@shiraz1736 2 года назад

Excellent craftsmanship, did you consider a closed enclosure with a larger woofer at any point, looks like your cabinet could handle the pressures quite easily.

@Gabster1 2 года назад

The Scanspeak 32W 12 inch woofer is a excellent woofer I love the sound that it makes Clear and relaxed Drums actually sound like drums, not compressed. The bigger woofers seem to loose a bit in sound quality and speed I am a big believer of very large volume for the woofer with a large port It seems to give a sense of a open baffle. but that is just me. I debated double woofers but the almost round design di not help.

@ny384388 2 года назад

Stunning build! I am particularly curious about your use of Acoust-X in the woofer cabinet. In this build you use it as a laminating "adhesive" in the woofer cabinet multi-layer wall structure, similar to your horn build where you also use it on the inside of the cabinet with a thin plywood laminate. I notice you also use Acoust-X as a thick unconstrained paint inside the cabinet including the bracing structures. Is it best used as a CLD layer between rigid structures or is surface application on surfaces equally effective?

@Gabster1 2 года назад

For internal walls that will not easily resonate to the outside just painting them is fine that is what the manufacturer recommend. For outside walls using various layers that are different is the ultimate way as far as I see it. Using Acoust-x in between reduces the waves from resonating via the outside wall. I did some tests may be one day I will make a video about it where I used it between rigid structures and non rigid like rubber and it did well I was concerned about it not drying but as long as one side is wood it will dry as wood will extract the water over time. when possible let it dry for a couple days before adding more layers. Please note this is how I do it and I could be wrong, but my measurements and listening tests are very encouraging.

Exact measurements are reasonably not critical it is a simple design in a way the woofer cabinet inside dimensions are a 19 inch Radius with 4 inches above the circle by 20.5 inches deep outside are 22x24 (wall is about 1.5 inches thick ) The Midrange inside measurements are around 6.5 inches radius at the widest by 16 inches.

For building this you need a workshop filled with expensive mashines like is shown here. If you dont have it you can forgot about that and rather invest the same money to get a high end speaker from you dealer. If a speaker needs to have this rounded geometry and fancy multilayer coverage can be be truly doubted. There exist lots of excellent DIY speaker that use conventional shape and sound great with simple MDF coated with whool or similar and even expensive commercial designs usually do not consist of this sophisticated multilayer stuff. I really doubt that this complicated procedure has that effect on acustic quality.
