Lanzar Optidrive...nice...

Koji Goliath daje oko 3kW na 4ohma...? Nijedan...skoro su duplo slabiji na 4ohma!
Board na Opti4000 je isti kao na GZ 1.6000D a ti Davore znaš kako je to dobar ojačivalnik, vidjeh na Ampguts-u, znači ako je ovdje kao kod SS XXX10000D mogla bi to biti dobra stvarčica!
Al ajde, treba vidjet koliko stvarno ima snage, slažem se...

ja kazem općenito, od pojačala u toj klasi i cijeni goliath bi bio moj izbor.

..... i onda se za cijenu tih pojačala nabavi nešto što ima ovakve navode snage...(denister, ti prepoznaješ to ) i pojede sva ova pojačala za doručak na normalnom naponu...a za istu cijenu.....čak i nižu

Mislim da si se dobro zayebo za cijenu...ako je ovo Stetsom?

[davor-ri]

je...cijena mu je koliko sam  ja našao oko 2500$$

[denister]

pa manje više onaj cijenik šta sam ti poslao je stari, poslat će mi na mail novi cijenik, a i tamo ti poše da je ono cijena sa ivom
a i nadalje vidio si da ono radi i na 12V

[davor-ri]

pretpostavljam da si teroru slao cjenik..a mogao si i meni....inače zanimljivo koliko struje povuče na bass signal

[denister]

da teroru sam poslao, evo ću i tebi...

[bego]

de i meni šalji..mail je [email protected]

dankešen

[davor-ri]

šta je..sad se svi popalili kad vide puno rms na niskom naponu 

[denister]

davore a šta kažeš na ovo 8000WRMS @ 12,6V :):) a nije stetsom ali je opet brazilac
ili vidi ovu razliku šta su mjerili

I have test results of the Stetsom vs. a DD Z1. First I would like to state that I am comparing similar size and priced amps and not what they are rated at. These power test are specifically for spl power comparisions and not to represent actual bench power test. And yes I know that I'm comparing a 3k amp to a 7k amp so you don't have to point it out. And if you think it's not a fair test then find me an amp that is 7k rating and similar in price and size and I'll be more than happy to compare for you. Now that that is said.

All test done on a single NSB90. The Z1 had 2 1/0 ground and power and Stetsom had 1 1/0 ground and power. These numbers are the highest of each test with other tests with in 100w of what is stated.

Z1 @ .5ohms rise to 1.74ohms 77.1v 44.2a 3400w

Stetsom @ .5ohms rise to 1.71 80.6v 46.9a 3800w
Stetsom .3db louder

Z1 @ .25ohm rise to .877ohm 60.1v 68.5a 4100w

Stetsom @ .25ohm rise to .90ohm 63.3v 70.3a 4400w

Stetsom .2db louder

One thing the Stetsom does that the Z1 doens't is when tested the Stetsom voltage will peak to 71-75v then level off at 63ish volts. So if I was to record peak voltage then the amp would be 5000 to 5200w. The Z1 in test just goes to 60ish volts and then goes to 59.9,59.8,59.7 with no peak. It just goes to show that with if we had a bigger battery the Stetsom wants to produce the 5000+ watts. Our battery can't keep the voltage up for it to do so. With big cell batterys being allowed the Stetsom is going to be a force to be delt with. Going to retest this week with more power wire going to the Stetsom like the Z1 had and a slight modification to the Stetsom. I'll post when that is done. If you live localy to me and would like to see the amp before you buy let me know and I'll direct you to who you can buy it from.
