AsciLab C6B Looks Good.....No, they Look Great !

[bears_t2]

You're braver than me. I surely wouldn't be soldering and $1100 speaker... They'd be going back 1st thing... Let them mess it up instead of me.

Yeah, I got approval from Ascilabs and they took responsibility if I messed anything up. Gave me in-store credit for my troubles I'm going to use on their center channel when it releases.

Had a tweeter with no output, troubleshoot with the manufacturer and found a resistor got knocked loose. Thankfully removing the passive radiator gave me enough room to get the soldering gun in there.

The pic shows that the holes in the circuit board are not filled with solder (to be expected on inexpensive single sided circuit boards (without plated through holes), or that the leads did not fully wet; indicating a solder wave or flux issue; or operator inattention during manufacture; there is a fair to good chance that you will, eventually, have to remove the crossover circuit board and re-flux and re-solder each connection on the circuit/solder side, for long term reliability...

Enjoy!

Hard to say not being able to see the underside of the board. I would give them the benefit of the doubt they know how to assemble an xover. I blame fed ex's subpar handling of the package if anything

I'm a bit suspicious of the original solder connection too. I can't imagine the dropping force that would be required for the weight of the resistor to break a solid solder connection. I can't tell for sure but it looks a bit like the lead was cut short, so not enough was poking through for a good connection, or when the extra length of lead was cut after soldering they also cut through the solder (I've done that).

Even then, from the resistor coating left on the circuit board it appears that it was also glued in place. Which again begs the question of how could the box be impacted hard enough to jar that loose without other things inside breaking? I just wouldn't think that the resistor would have enough mass to turn an impact into the force needed for breaking the solder connection and the glue to the board.

It would almost seem like it was damaged during assembly, possibly pushed back into place after and then jiggled free when jolted in transit.

Oh yeah, definitely thrown around during shipment. But with that said, could be a blessing in disguise. May have had intermittent dropouts. The kind that drives one crazy trying to locate, isolate.

Funny you posted this up, photo. I always pull XO out, to do a look see on new speakers I received. For the reason you found on yours. I also look at the speaker connector's to each driver, make sure they're properly secure and the right connector sizes.

They arrived! 5 days to get from SK to Colorado, not bad.

May I ask what the customs experience was like for you? 5 days is super fast so I'm guessing the package wasn't held up. Did they submit a bill to you for tariff tax, and if so how much did it cost you? Thanks in advance for any insight.

Very favorable review from Amir...they must be really good speakers !
Slightly different model though...C6B has a better woofer apparently, but if you are using a sub as most do it shouldn't matter....835 a pair includes shipping.

AsciLab F6B Bookshelf Speaker Review

This is a review, listening tests and detailed measurements of the AsciLab F6B stand mount speaker. It was sent to me by the company and costs US $835 for a pair (shipping included). In black, the F6B seems formal with a very clean design. It feels solid with sense of precision. Compared to...

No additional fees or charges. $200 shipping which they have now included to the listed price on their website.

C6b woofer, tweeter and crossover are different from the F6b.

 

[isolar8001]

C6b woofer, tweeter and crossover are different from the F6b.

Thanks...I see now on the ASR thread more clearly what the differences are....

How to Speak AsciLAB :-

S= Signature model, using all Purifi drivers.

A= Purifi Aluminium woofer and ceramic-aluminium tweeter.

C= Ceramic Aluminium woofer and a ceramic-aluminium tweeter

F= Fibre woofer and an aluminium tweeter.

B=Bookshelf

C=Cardioid

The middle number represents the diameter of the main driver in inches.

The final letter denotes the type of enclosure.

BX8C and BX10C are the Sub bass cardioid extension modules.
