Anyone running dual identical/mixed subwoofers or have upgraded from 1 sub to 2 subs, how much of an improvement was there and any other observations?

 

How have you placed your 2 subs?

 

Thanks

Hiya

 

Yip, running two Veloydyne CHT 10's via a Yamaha 3060 Aventage Receiver, one is front left of sofa, other is back of lounge to the right of a bookcase, IMHO much more.. er.. visceral ;)

 

When watching Atmos Blu ray the audio  is SPECTACULAR !!

Hi

 

I am currently running 2 x SVS SB2000s across the front of the room at one-third wall length spacing. Compared with just one sub the difference is a much smoother and more even bass in the room.

 

Dual subs is well worth doing in my experience.

2's better than 1, 4 is best.

 

Where to place depends on your room. Can you describe the 4 walls and ceiling in relation to where you sit?





Swype on iOS is detrimental to accurate typing. Apologies in advance.

I went from one to two Pc13 ultras.
While two offer a little more output, the main reason is the help remove peaks and nulls in the frequency response, plus two (or more) offer the ability to create a wider sweet spot, smoother response over multiple chairs. Valuable if there is more then just you listening often.

And the best way to place subs is to measure them, sub crawl is a cheap free method. REW is better, but you need to buy a mic (about $100). That $100 is a very worthwhile investment is you are spending good money on subs.

Warning, the best sounding position for a sub is often the worst position aesthetically.

2x pc13. Jelaous. Do you have them calibrated with a umik?

I have 4x15" drivers was going to diy 2 dual opposed sealed subs but was procrastinating getting it done and now we just bought a house and lounge is a bit on the small side so thinking of making a box in the attic with a hole in the ceiling and running them as IB.

Yep, calibrated using REW and a Mini DSP, then xt32.
I also have two mid base subs directly behind the seats, so running four subs all up.

It's a rabbit hole, once you start it's hard to stop. I am still tinkering trying to get a better sound.
