Help for additional parts for C6B speakers

[Jiraya369]

All these "maybe" should be enough for you so to get an amp that it's not a "maybe".
Like the one static suggested, or similar.

Ask yourself if you can enjoy your music while worrying about a potential failure.
Peace of mind is one of my essentials, you're maybe more relaxed than me and that's perfectly ok, it's your gear after all.

it's because i was concerned that i asked, and you dont know the answer and dropped a bunch of maybe's again lmao

i dont think i listen that loud, perhaps 88 db peaks so at 1m it should be fine but we'll see. you didnt mention anything about topping's protective circuitry being hyper aggressive and shutting off on 2 ohm loads in amir's reactive tests in some reviews, so i had a hunch you're just as clueless as i was lol

i understand that lower impedance = higher wattage = more power = more heat, and that means better cooling is needed.

But i was just asking what could go wrong right now and you just dropped a bunch of maybe's. I mean i know that MAYBE it'll get fried, MAYBE the amp wont be cool enough, MAYBE the speaker might explode, but dropping just another maybe isn't really helpful as im just as lost about the subject as i was in the beginning.

Welcome to the world of Sokel.

Maybe your amp isn't good enough!

Maybe.

Maybe....

I haven't mentioned Topping simply because they rate their amps at 4 Ohm minimum, and that's all we need to know.

If they could go lower they would be the first to advertise it. And if things go south they can very well say that is your fault.
So...

yeah keep yapping pal, you're saying the same thing and raising the same concerns i did in the original post, i dont want to waste further time on this.

if someone knowledgeable knows exactly what's gonna happen and says it then i'd understand.

I'm afraid you'll have to provide a boatload of data so people can calculate a likely outcome.
From your room temperature , your mains voltage, your listening level along with the track so we see its spectrum, peaks. range, etc, etc.

Marry Christmas, mic drop, see you all in a couple of days!

 

[staticV3]

so the amps will turn off before playing the c6b?

If the Amp is conservatively specced and well built, it will play just fine despite not being rated for <4Ω loads.

If it is realistically specced and well built, it will trigger over current protection and shut off.

If the Amp is realistically specced and poorly built, it may damage itself and perhaps even the speakers.

Exactly. Operating an amplifier outside its specification isn't an exact science. It depends on so many factors, that the only safe approach is not to use an amplifier outside its design specification. You may get away with it, you may not. You may get away with it for seemingly long time but eventually you get a failure which may (or may not) be caused by continuously exceeding the design specification. You're asking for certainties where there are none. Just get an amplifier that's 2 ohm rated.

I do know what I'm talking about but it makes hard that you can't read charts.

Here's one of them, showing the cooling needs of the amp (a typical TPA3255) at different loads (and it does not even show 2 Ohm! )

View attachment 499526

Power losses (=heat) goes way higher as load goes tougher.

Hope you find a good amp!

It doesn't show 2R because Figure 10 is for BTL configuration. But since 1 channel of PBTL is essentially the same as 2 channels of BTL the 4R line will be about right.

makes sense, i just wonder why erin nor ascilab talk about this, it's not my job to look for 2 ohm amps, they only talked about good 4 ohm amps. Even the la90d doesnt do 2 ohms.

 

[staticV3]

If you buy passive speakers, then it is your job to buy an appropriate Amplifier.

If you don't like it, then I'd recommend buying Actives, where the manufacturer has chosen appropriate Amps for you.

 

[Mort]

yeah i saw that and that's what i was concerned with but why are erin and ascilab only talking about 4 ohm amps then?

This is from Erin's Review. It's right in the specs.

"

• Impedance: Nominal 4 Ohm (min 200Hz / 2.6 Ohm)"

I have an LA90D driving C6Bs without any problems...I suppose I should add... "at the moment"!

However, AsciLab have said when asked about the C6Bs..."It has a bit lower impedance, but required wattage is not that huge. For example, we tested PA5II to drive C5B and C6B to the maximum output. It was not that big different with C298 Purifi Amp. LA90 would be enough to drive them."

i remember reading this, that's what im saying, ascilab themselves tested it, so why is everyone else acting so snobby about something they dont themselves know about properly? I guess I wasted my time coming here.

Thanks for the great comment. Everyone here was just as clueless as me. Or they think they know more about speakers than Ascilab and Erin.

Amplifiers have protection circuits. In almost all cases, they will shut down before any damage is done to them. The protection circuit is a black box though in that we don't know how it is designed. It may have blind spots to what could still damage the amp. In all the years I have tested amplifiers to protection, I have only had two die on me and both were the power supply, not the amp. Net, net, it is incredibly low risk here and personally I would not be worried about connecting an amp to an out of spec load.

Further, the most energy required from the amp is below 100 Hz where the bass is. It is rare to have music that has its highest amplitude above that where C6B has its minimum.

And of course, all of this depends on how loud you listen. You say 88 dB but humans are not good SPL meters . And at any rate, you need to know the SPL from 200 to 500 Hz, not some average.

Finally, I test a lot of AV Receivers which have minimum impedance of 6 ohm yet work perfectly fine at 4 ohm.

If I were you, I would get whatever the most powerful amplifier you can afford and not worry about its impedance spec or that of C6B.

hell yeah that's some good info, exactly what i wanted and from the big man himself. Thank you

 

[amirm]

and DANG IT that amp looks so nice but the thing is, the mini300 is available where i live for near msrp, i couldn't resist the fast shipping, warranty and low price.

FYI I have a mini 300 here and plan to test it in a couple of weeks. I could test it at 2 ohm and settle the argument if you can wait.

Hey, I also bought a mini 300 and pre-ordered the C6B (based on this ASR's praise).
If you had any development to this be sure to let us know, since the Topping is recent it's now or never to return and buy something else in my case I suppose.

i mean im using a mini300 for my c6b and at 50-70% volume i get scared
