Magico Q-Sub 15’s

I understand about the realism of a car crash, explosion etc. in a home theater. In stereo you are not going to be listening to a car crash etc. unless your still part of a home theater/stereo setup. And if bass is as The Sandman and others state is omnidirectional then why placing the subs facing each other I still find of interest and am curious about.

I have two small sealed subs behind my A3's and decided last night to turn them towards each other just to experiment with. I don't have a tech team or software to work with.
 
The omnidirectionality is theoretical - the drivers, the box, and the room all play a part. And rotating the subs might change the phase.

You can either adjust by ear or purchase some reasonably priced audio analysis gear (microphone and software for your laptop) and then make adjustments based on your measurements.
 
I had an expert help set up my subs. He used his ears and his own music/test materials. In the end, he placed two subs facing each other and not facing the listener.
 
Mike mentioned pressurizing the room by their placement. I would think 2000wpcX2 could accomplish that. And I would think software would take care of any phase issues. I have read articles about omnidirectional sound waves over the years and I'm still left with trying to understand this kind of sub driver placement.
 
I've always tried to put the subs in whatever configuration that gave the flattest bass for the room. That way you can do the least amount of correction with the DSP. In some rooms it's having the drivers face the listener, in some it's facing at various angles.

With some subs to be able to get deep bass 15-20hz the sub has to go in the corner because it needs the room to help.
 
Questions:
At what frequency are these Magico subs kicking in? Does the DSP affect only the subs?

As far as I know, you can’t really “aim” the bass... the waves propagate in all directions.

At least, while human hearing is able to determine the source or direction of high/ mid signals, it is much less able to do so for low frequencies. I also think that might also have to do with how low frequency sound waves propagate.

I will be joining the Q-Sub club in a few months. Thanks to my favorite crack dealer Mike :-)

Now the waiting begins. I have a smallish room so the set up should be relevant to a lot of other addicts. I'll post after the Dream Team completes the tuning.

How large is your room please?

Do your M400 get power from the P20?

Yes. Both mono blocks and the subs and the MSB DAC to the same P20. The power level never rises above 60% of capacity. I feed the P20 with a 20 amp dedicated circuit from my breaker box.

I don’t think it ever will get much past that if at all.

I have interest in the P20 with suitable headroom after having a P10 which I did push a few times to shut down [emoji851]

Congratulations Eri. I have heard a QSub with the M3 at my local dealer. That was in a really big room, and he only had one sub (two 15" drivers). Are you going to get two subs (four 15" drivers) in your room? Can you share a photo of your room? I'll be very interested in reading about the installation and sound. Thanks.

Peter,

I've purchased two of the Q-sub 15's to replace my two REL G1's. When they show up I will post before and after pictures of the installation and tuning process to give everyone the benefit of the lessons we learn during the activity.

That would certainly explain some things. Two subs is definitely the way to go. The Q-Sub technology gives total control over the subs (including Q adjustments, crossover type and frequency and dB adjustments, etc.) making integration seamless.

Mike, it sounded excellent when I heard the combination. I've since heard that system without the sub and it was not as enjoyable but other factors were involved. What things would having one sub explain? And how much does it cost to buy two QSubs?

Do you think two Qsubs with the M3 would sound better than one M6? What would be the retail prices for those?
