Vibelink amp Photo Gallery

[slartibartfast]

Why is this even being discussed? Like I said, you set your stuff up the way you like and I'll do the same to mine. All of this because someone noticed I had two subs.... And this is the very reason why I'm not on any forums with the exception of this one. It's always "I'm right".. "no, I'm right".. Who cares???

Maybe the point is that normally everything below 100Hz is mixed to mono anyway. With Stereo subs you can set the crossover point as high as you like as long as the sub can handle it of course.

I mean, that's kind of the point of the forums, no?! To exchange ideas and share our opinions...
Not sure I understand your reaction there to a reasonable discussion that came up naturally

Well, let's calm down, folks .

@Puzz just posted a photo in the Vibelink photo gallery thread. He wasn't asking for advice about his audio, and the sub is not the subject .

True but the subs in the picture aren't even connected yet. Is it safe to connect subs to the speaker terminals of a Vibelink amp?

I know with REL subs connected at speaker level to a class D amp they recommend a different method, I'm not sure what that method is because I don't have a class D amp, but worth researching first maybe!

I have a very vague recollection of that advice from REL being disputed here

I imagine it could be disputed but worth knowing all the recommendations

@Puzz I’m not always right, far from it.
Our hearing is undirectional below appx 150 Hz (that’s a fact, not an opinion). Therefore running subwoofers in mono combined with smart placing can reduce total room interaction.

Ok. Enough off topic from me (for now).

I don't think anyone was talking about that until you came along, but I understood.

Disputed? Here? Surely not

Sharing and discussing is fine. Cramming it down someone's throat when they didn't ask for it in the first place is just another form of harrasement. If I'm happy with the way my system sounds, why should I listen to someone else spouting off that I should set something up differently when it's perfectly fine the way it is?

Davros "YOU WILL OBEY"

There isn't a set rule with subwoofer setup, although high passing speakers and low passing subwoofer, with some kind of alignment box (wiim can do this but only for a single sub, not with multiple subs) and PEQ is recommended. especially with more than one sub

ie minidsp HD, I'm using one for a 3 subwoofer HT system, and the fourth output is used in a 2.1 system, so quite handy little box

If I used binding post adapters and put them in the WIIM's speaker cable inserts, couldn't I hook up small gauge wire to it and run it to the hi-level or speaker level inputs of the subs? It's just sending a very small signal to the subs. It's not like trying to hook up two pairs of speakers to the WIIM amp..

I'd be wary of connecting subwoofers to a class D amp via high level, due to risk of damage to the amp and or subwoofer. Not because of power draw (as it's literally nothing) but something to do with class D. Just stick with low level to the sub.

Even if it was possible, there is no benefit of doing it the "rel" method, ie full range to speakers, full range to subwoofer then using the subwoofers own crossover.

If the amp device has a high pass, sub out, etc (like a AVR) then just use that and the bass management feature.

If for some reason you want left and right bass, then you're want a pre amp that has left & right pre outs for pre power setup, or a multiple subwoofer pre outs.

I think Denon AVR's allow you set mono sub, and left and right subwoofer pre outs- and also front and rear sub layout. Probably some high end av pre amps also. My AV pre amp has 3 sub outs, but there is no mono and left & right setup.

Have a look into this box, if it would work in your system. You need considerable EQ knowledge though, and figure out how to avoid stacking EQ in the Wiim

You'd take the pre out from your wiim sub out into that, then connect your 2 subwoofers into that. Run sweeps, and reference timing, do some MSO calcuations (someone on another forum did that for me) then import that into the console.

It's pretty complicated and NOT for the noobie, I know a bit (can run REW sweeps, have a idea what PEQ does, can import corrections into minidsp DSP) but the subwoofer alignment and correction values for multiple subs using MSO are way over my head.

Also for more info regarding high level & low level read this, determine what is relevent in yours.

I have several systems, subwoofer setup

1) A HT system, 9.3.4. Single subwoofer cable from av pre amp into the Minidsp HD then into the three subwoofers. Option to use bass management for stereo, or full range L/R
2) A additional 2.1 connected to the same av pre amp as above, left/right pre out goes into a Outlaw ICBM-1 then onto power amplifiers, and from outlaw into the minidsp second input, then onto fourth output.
3) A AVR PC 2.1 system.

if your speakers and subwoofers are same position from the walls then you might be lucky with timing- I'd still run a couple of REW sweeps to check though.

1) Run a left subwoofer sweep
2) Run a right subwoofer sweep
3) Run a combined subwoofer sweep

if 3 looks worse than 1 or 2, then cancellation is going on.

Thanks but I'm not going through all of that. I refuse to use EQ and using the least amount of electronics for the most pure, unmolested sound. I'm then going to just use no subwoofers or simply return the unit.. I think this is personally a downfall for the WIIM Vibelink amp. It should've included at least one subwoofer output. Now, knowing you can't even use a sub with this amp is going to be a let down for many potential buyers..

Disagree with Subwoofer PEQ , it's essential if it's all over the place. I'll find my before and after with subs, I'll need to retest mine, before and after, individual and combined etc.

For speakers, yes I sort of agree, in a well sorted room, good speakers, likely you don't need it

What are you feeding the Vibelink with?

 

[rccarguy]

Maybe look for a standard "hifi pre amp" as that will give more flexbility. Off board DAC if needed, no EQ, or add peq or power amps as needed, biamping etc. I use one of these in the hifi
