First Impressions about the Truth B2030A
Reply #6 – 2008-09-05 11:09:13
Is the B2030A silent? I mean the amplifiers of course. Any audible hiss and/or hum at all? No noticable hiss or hum in the middle of the night with no other gear in the flat switched on which could audibly raise the noisefloor. And thats with a connection to an onboard soundcard to a laptop (see further down for the "why"). By the way: the speaker's power-connection is properly grounded, as opposed to typical consumer powered speakers.As for the 2kHz peak you claim exists. No such peak exists on the passive version. One of the biggest gripes I do have with the passive version, as opposed to the active version, is that they obviously used a very stiff surround on the passive one to raise the speaker's Fs substantially, thus resulting in a high F3 for the speaker. The active version apparently uses a soft surround, allowing a far lower Fs, and far lower effective cabinet tuning. Perhaps something that was done to act as an incentive to purchase the active version over the passive one? No peak at 2KHz, but one at 9 - 12KHz - the stuff which makes the "SSSssss" of hihats sound more sharp and aggressive than they should be. I could imagine that it wouldn't bother many people and that just i instantly noticed it, because i'm sensitive at that range (after all, with the early vorbis encoders which created a similiar flaw, almost no one else noticed it as well for half a year - only later a low amount of people started to notice it too and the issue was taken seriously). I also wouldn't exclude the possibility that it may be intentionally by design (after all, it does make them seem slightly more "accurate" than natural). In any case, if one does have an EQ ready dedicated only for output, its a non-issue because it doesn't require much adjustment). I cannot comment about the other points which you made, because honestly i do not understand them (i lack indepth knowledge about speaker-internals). Or do you mean the crossover between woofer and tweeter? That one is at 2KHz in the active version.what source are you using and what kind of connection ? Right now, i'm still waiting for an external soundcard to appear on the market which fits my needs. Until that happens, i'm on an onboard laptop soundcard, which coincidentally does not have the typical flaws associated with laptop soundcards (no audible hiss, no strong signal degration). Since that means that i do not have balanced signal sources available, i didn't bother with doing an XLR connection and just used a properly shielded 2 metres Y-Cable from 3,5mm TRS stereo to 2x 6,3mm TRS mono. - Lyx
