Тест усилителей мощностью 6-7 кВт

Не так давно наткнулся на тест усилителей, мощность которых лежит в пределах 6-7 кВт, который провели наши зарубежные коллеги. Данный материал показался мне достаточно интересным и информативным. Думаю стоит его опубликовать и у нас на форуме, надеюсь многим пользователям этот материал будет полезен :hi:

Участники теста:

- Digital Designs M4a

- CT Sounds 7000.1d

- Popcorn Sounds 6k

- American bass 750.1

- JBL Crown 6000GTi

- Sundown Audio NS-1

Условия теста:

- резистивная нагрузка - 1 ом

- питание, много Кинетиков и хорошая подпорка приличной емкостью кондеров. во время тестов питание не просаживалось ниже 14 вольт.

- замеры термлабом проводились на нагрузку в 0,25 ом (пара пятнах Tantric HDD15) в хонде CRX.

JBL нереально крут

Подключение в 1 ом

Импеданс 3 ома

Мощность на сабах 6400вт

Этот тест идет "прицепом", так как проводился немного позже в другой машине, на том же железе.

Sundown Audio NS-1

Заявка - 6500вт на 14.4в

Факт - 1 ом / 5800вт / эффективность 72% / небольшой клипп

Мощность на сабах 6550 вт

Импеданс 0,9 ом

* Замер давления производился в другой машине, на том же ящике и тех же сабах. За точку отсчета взяли результат CT 7000.1

Результат NS-1 меньше на 0,7 дб (т.е. ~ 157.9 дб если бы тест проводился в CRX).

Итог теста:

CT Sounds 7k - 7,930w - 158.6db

American bass 750.1 - 7,100w - 158.2db

Digital Designs M4a - 6,490w - 158.0db

JBL Crown 6000 - 6,400w - 158.2db

Popcorn Sounds 6k - 5,700w - 157.1db

... и на последок впечатление человека, который проводил тесты, о каждом усилителе. привожу в первоисточнике (без перевода), чтобы чего нибудь не упустить или допустить какую ошибку. Текст вполне простой, школьного курса английского вполне хватит для понимания сути :hi:

CT Sounds - solid performer. Made the same power at 10.5 dcv as it did ~ 14v. This is great news for battery guys. That puts it in DD territory as far as low voltage beastliness. It's also a big bish if you're into that kinda thing. The white is clean but makes scuffs, scratches, smudges stick out like a **** on a fish. The pots on this amp were the "cheapest" of the bunch. I don't care for the plastic Phillips head pots. It's not a deal breaker. Just an observation. bass knob/Voltmeter also earns bonus points from me. It has a clipping indicator on it too, but it's not of much use. It started flickering around 40acv when it made over double that clean. No surprise there since I've been telling y'all forever that those things are just a light show.

Side note on the CT: it's the only amp here with triple inputs. Ryan only had (2) spare leads so we tested it first with just duals. But we agreed to test all the amps the way they were designed. Fwiw... The 3rd input was worth .2 on the meter.

AB 750.1. I've got love for the VFL's. What I don't care for is AB's ratings of them. They've seemingly gone to "max" power ratings. The amps are solid enough. They don't need inflated rating to sell them. Do they? Bonus points for the AB being 18v stable. It would walk these others once you get past the 16v CT and 15.2v DD. But... That doesn't help the 12v guys. It's also a big ass amp physically. It dwarfs the M4a in size, but not so much in score. Still way up there on my recommend list even though I feel like it underperformed here. Most efficient of the bunch by what probably amounts to margin of error.

M4a... Oh how I love thee. Smallest amp in the bunch and perhaps a bit of an underdog in this one. It fell short of DD's 7k rating, but still made the most power per sq in of real estate. Low voltage monster. Bulletproof as they come. Doesn't like .25 much so it took a slower roll to get it there but it did fine. We tested the protection circuit pretty good finding the sweet spot on the roll. .35 is the lowest I'd recommend burping this one. Has the lowest operating voltage of all these amps. 15.2-15.3 or so is all you're likely to be able to run. Not a concern for 99% of people but its nice to have a little cushion in the voltage.

JBL Crown... This is one of those holy grail type amps. Its hyooooj. Entirely impractical. Not so efficient and 1,000% awesome. Do want. This test absolutely demolishes the efficiency myths floating around about this amp. It's really a gigantic, retardedly bad ass SQ amp. It's also a 2 channel so it was bridged here. It ALSO only has single inputs. And I'm now cursing the fact that we didn't test it with duals. Just might have caught that big white bish. This amp is just plain sex and the output test was just for funsies but it impressed me even though I've heard it before. This amp will be mine. Oh yes... It will be mine.

Popcorn Sounds... GFY.

Sunown NS-1 - Most expensive amp in the test. More optimized for high voltage operation so it was maybe at a disadvantage in this one. Still did well at 14v, but this one and the AB would really start stretching the others out with more voltage if that's your thing. This amp is basically an M4a that is operational to 19v. Which is awesome considering how much I like the M4a.
