Oare care este cea mai potrivita alegere de proiect pentru o incinta audio care sa puna in valoare un asemenea difuzor ?
La o prima cautare pe net , am gasit un site japonez :
http://kiirojbl.web.fc2.com/audio/audio88.htmAcolo se specifica cateva detalii , unele absolut firesti pentru o solutie BR ( 320litri intern , cu un acord la 30 Hz ) :
" PD.2450 (3) and is soon playing with never change, mono 6 way and phase time of demolition is imminent, we have got a learned or rather.
It was found that it is possible to greatly adjust the bass texture of the from the addition of mid bass.
The bass part, 25cm4 shot of mid-based, 38cm4 shots of woofer of the V-shaped baffle, and has been constructed from 3-way that 46cm1 shot of subwoofer of pseudo V-shaped baffle.
For example, if you raise the level of the subwoofer, feel that bounced no longer raised the level of the woofer section will retreat.
Therefore, increasing the level of woofer part by lowering the level of the subwoofer, the But I feel that bounded if there is a V-shaped baffle seems punch comes out, this time it will not match the texture of 2392 + 2490H.
Therefore, adjusting the cross of the mid-base and woofer part.
It's 120Hz is a strong character of the woofer section, but the honest sound of mid bass becomes the dominant Lowering up to 100Hz.
Mid base for us to bridging the gap between the texture of the woofer section and the 2392 + 2490H.
I wonder if there is a need to 3 split the 300Hz or less?
When Initially I thought quite doubt, it is now I think not bad by now.
Taking advantage of the meager know-how gained through these adjustments, and I tried to re-adjust the yellow horn system.
Clear controls, such as mono 6 way is hard, but still the relationship between the change of equalizing and cross of adjustment and sound've got to understand than before.
For boost of the lowest band was excessive, bass atmosphere of has changed significantly when a little lift the to suppress 50Hz ~ 80Hz here.
On the other hand, it does not start unless made the ... box and say what happened to PD.2450.
However, I was lost in the volume of this box.
And I had planned a 500L ~ 600L initially, but when I checked on the design software of various box 300L position is displayed as appropriate volume.
Recommended volume of PD.2450 has become a 130L ~ 400L, but numerical value of this 300L is not visible to the so abnormal, but still ...
I want to and because it is for the subwoofer of 61cm to more big box Furthermore, unit is 36kg and heavy for, you invited anxiety for attachment to baffle plate.
Is it can be matched well the screw holes with the screw holes on the unit of the baffle plate when installing the unit, then, do not than when are mounting a long period of time no longer removing the unit and the baffle plate and is sticking unit.
These things also harassment.
So, this time it was to be linked with the bolt in order to be able to attach and detach the back plate and the baffle plate.
Attach the unit to the baffle plate, then, work be attached to the baffle plate each box of whether not easy.
In addition, even if accidentally baffle plate and the unit is stuck, it intends Yasukaro deal as long as it can be removed from the baffle plate per box.
Then, remove the back plate if you feel like increasing the box of volume, so you can easily increase the volume to be attached the extended portion of the newly produced the side plate.
Eventually, it was decided to design an effective volume 300L in the goal. Use the 24mm thickness China plywood.
Inside dimension volume is 358L (inside dimension 852W × 702H × 600Dmm, external dimensions 900 × 750 × 663mm).
Reinforcements, ducts, unit, and calculates the volume reduced by a small amount of the sound absorbing material about 38L.
Thus the effective volume 320L. About duct tuning off the 30Hz little.
Duct openings 200 × 130mm, is two is duct length 339mm.
Because the dimensions of the mounting holes on the unit has not been shown in the brochure, where it was a hole with a diameter of 568mm, this is released.
Unit does not enter at the little later.
You got Kotonaki by overlapping 15mm China plywood of a hole of 578mm because there is no way.
For this reason, the thickness of the baffle plate has become the 39mm.
Although other also manufacture there are here and there mistake was repeated seesawing, I was able to somehow complete. "
Pentru a intelege mai bine acest proiect , foarte deosebit fata de proiectele clasice cu difuzoare de dimensini normale ( pana in 18" ) va prezint un proiect asemanator de la o firma de renume ( P-Audio ) proiect diferit pentru ca este destinat unui difuzor de doar 21" , si care probabil a stat la baza celui japonez descris mai sus :
http://www.paudiothailand.com/pdf/Syste ... Y-121S.pdf . remarcati cata importanta s-a dat structurii antirezonante a incintei , pentru a nu se rupe in bucati
.
Nu este de joaca cu greutati si volume mari , cu difuzoare care genereaza presiuni incredibile ... acest difuzor este din categoria difuzoarelor din prima liga si cu siguranta joaca doar in finala mare !
