Mozemo mi i u tu sekciju :D

U svakom slucaju stedimo struju... :D Pivo, vino, radzu i ostalo fermentisano voce pretvaramo u korisnu toplotu a mi ne ozenjeni i u mehanicki rad :D :D

Al zato vi imate A klasu :D :D




Pozdrav svima!

da mi mozes da postavis identicnu kao ovu skicu posto se ova dole razlikuje koju si dao sa dimenzijama.Razlike su pise da se desna strana postavlja pod uglom od 75 stepeni a leva je nacrtana da ide racno sto nikako ne odgovara ovoj slici ,druga stvar je ivice sa prednje strane su skinute kod vas na slici sto mi sigleda mnogo lepse nego da je coskasta.U napred hvala

Stigo je HF i horne...

Horne kad sam otvorio samo sto nisam pao na du*e :D Koliko su velike!!! :D Na sajtu su delovale kao neke piezo igracke :D

Sto se HF-a tice delujuju kvalitetno.. Videcemo slusne utiske.




Pozdrav!

POST 5:

BackEMF :AES power handling is perhaps one of the best defined ratings for loudspeakers.

It is simply pink noise filtered between 125Hz and 8kHz with a peak to average ratio of 6dB and applied over a period of two hours. It is one of the better indicators of both the thermal and mechanical aspects of power handling.

post 7:

museav:I believe that RMS power is a misnomer, it has become commonly used but it really is a meaningless value and is actually the calculated power based on RMS voltage and current measurements. Also realize that Program and Peak ratings are calculated rather than measured values, the AES test signal used has a 6dB crest factor, the peaks are 6dB above the average, so the "peak" power is 6dB (4X) the continuous power while "Program" is essentially a made up rating to reflect that the test signal is not the same as a typical program source such as music and it is typically simply 3dB (2X) above the continuous rating.

There are numerous different speaker power rating schemes, some intended for individual drivers and some for full range devices. AES ratings are quite common and you might see IEC/EIA ratings as well. A few manufacturers use their own proprietary hybrid or modifications of some of the standard test methods. Many of the differences relate to the driving signal applied (bandwidth, filter slopes, crest factor, etc.) and the time the signal is applied. There are pros and cons to each method. And do not think that marketing is not a factor in this, how many people really understand or even notice the differences in the test methods or specifics of the ratings versus those that simply look at the numbers? So if your competition changes the test methods used or how the information is reported then from a sales perspective there is definitely some pressure to do the same.

As the specs for gaff's sub show, the length of test is a factor can also be a factor as longer test times can start to reveal long term issues, typically thermal, when the speaker is driven continuously for long periods. Not necessarily applicable for your 2 hour show with live music but perhaps relevant to the all night DJ with heavily compressed source material.

One of the limitations with current power ratings is that a speaker could have a noticeable change in response before reaching the rated power and that would not be identified. There are also a lot of calculated vlaues reported for both speakers and amplifiers. There is a move within AES and by some of the independent speaker testing labs to develop new speaker and amplifier rating systems that are based on the actual voltage and current measurements rather than calculated power levels and that for speakers define the power limit as when an audible (3dB) change occurs in the frequency response. This makes a lot of sense to me as it means you are really looking at when the power starts to affect what is heard and it is also a condition from which most speakers could recover.

Ma hoce, to otvorio ko iz sale...:D al je*e me nesto player-ov sajt nece nista da mi otvori...

Extra horna jbt., ma malo je reci horna to bre "hornetina"...:D:D velika jako puno bas...:)
Ja uzeo u proelectronic za 8e isto ABS materijal kao kod te, i nisam se bas nesto razocarao, na izgled izgleda super...:):-)

Samo jel je bolt on ili screw on horna...??

ackopk:Sad cekam kondove iz Proelectronica za koje cu verovatno platiti postarinu... I naravno kalemovi :D


I ja isto cekam., al Euro-a da mi odradi to...:D:D:D Al izgleda zauzet mnogo, ne stize od tolikog posla...:-);) Al strpljiv sam ja...:)

Pozdrav...!!

@44250

Hvala za link.

Mislio sam na neki zvanicni dokument. Znam i ja u principu osnove merenja. Ima na njihovom zvanicnom sajtu ali se placa clanarina... Ukoliko nisi clan ne mozes da preuzmes dokumente. :(



@Stefan117


U proelectronicu su 3/8" ako sam dobro video...


U pravu si... hornetina :D Valjda ce i tako da se cuje :D

Ma to je njihova neka mera, ne znam ni sam za sta je tj, kako se gleda al su sve horne za 1'' drajver...!!

Ma hoce sigurno, ni nesumnjam...:) Samo veca horna od LF drajvera...:):)


Pozdrav...!!
