difuzor panel - Page 4

Znaci, ako je soba dovoljno siroka, moze i bocno (kad se ispostuju kriterijumi), ako je preko 3,5-4m visoka moze i na plafon....... a ipak, znaci u vecini realnih soba koje mi imamo - samo zadnji zid ....?

**NLP** · 21-10-2008, 11:11 PM

Da. ... a mora? da eliminuje? i ni?e/ niske frekvencije!

Ok... to se podrazumeva..... nego sam bio u dilemi vezanoj za tretman iza monitora, vidim da ovde preovladava misljenje da ipak treba ici sa apsorberima.

Meni bi verovatno sweet spot bio oko 2,5m od prednjeg zida....

**NLP** · 21-10-2008, 11:36 PM

Da, ako je prosječno "mala/ srednja" veličine prostorija.
Difuzori nisu efektivni u niskim frekvencijama ako nemaju prostora da "zadi?e vazduh" kroz dovoljno veli prostor.
Zato neka postavljena granica (nasuprot reflektoru)... od 565Hz diffraction limit u prosječnim prostorijama.

a shto je sa diffractalom DFR73?
dubinom od 8"(25cm) reagira do cak 20hz.. osim difuzije u igri je i apsorpcija
http://www.rpginc.com/products/diffractal/index.htm

kako bi se on ponasao u manjim rezijama?

Tu su odgovorili na temu apsorbcije i difuzije (ctrl+f="Performance Specifications"):
http://www.rpginc.com/products/diffractal/diffract.pdf

... "dubinom od 8"(25cm) reagira do cak 20hz"...

Verovatno misli? do 20 kHz?!
Do 20 Hz ne djeluje taj difuzor!

Dubina difuzora definuje spodnju "granicu" difuzije, a ?irina posameznog jednog vala definira najvi?e frekvencije na koje efektuje difuzor...

Diffractal difuzori su vi?estupanjski difuzor: "second generation Diffractal? (DFR72) contains two nested QRD?s, thus forming a diffusor within a diffusor..."

uh..da! greshka, ne 20 nego 20k..
sta ces, brza ruka od mozga

u svakom slucaju diffractal mi je vrrrlo zanimljiv, pogotovo 73-ojka,

kako im se krecu cijene?

tnx, NLP!

Nema zašto!

Ako bolje pogledaš dokument vidiš da je difuzija ispod cca. 565Hz "besmiselna" (druga priča) jer več običan reflektor... :
"The diffusion coefficient is also compared to a flat reflective panel which exhibits decreasing diffusivity with increasing frequency."
