Greetings!
Is there any difference in how to stack reflex bass boxes?
For example 2 boxes can be stacked in many ways,which way is the best?Does it really matter?
Thanks!

Reflex cabinets are not finicky as horns so they can be stacked to your liking. The main concern should be having the proper height to perch your full-range cabinets on top. I only use doubles and keep them standing up for this precise reason.

Personally I normally stack with the ports together, whether the cabs are side by side or one on top of the other.

Look at the RC1 system. All makes perfect sense to me.

Thanks guys! I thought that it dont really matter that much how you stack reflex.
What about in terms of spl,wouldnt 2 boxes both on the floor be better or does the same thing occur when stacked on top of each other?

Seems to have ports bottom and others in the "middle".Can you open it a bit more,what do you mean?
I bet it sounds nice but thats one ugly ass sound system

That would only make a difference if you are using limited quantity. Whenever you are using limited quantity, you are trying to extract every bit of SPL possible.
If you are only using two single boxes, you can always toss them in a corner and achieve the boundary effect while having your tops sitting at the proper height.

It's probably more important to stack them whichever way gets your mid-tops to the optimum height.
Like many things it's going to depend on the particular cabs you're using them and in what environment. Try the different options and go with what works. If you can't tell the difference then that gives you an answer too.

number 3 should have a little lower tuning than number 4, so try those two options and if you hear no difference, any stacking will sound the same.

Getting a port coupled to floor is what is firstly does, then, as much of the energy is through the ports, it gets the next two in the upper body/face area. It's supposed to be ugly, it's an industrial overkill type of thing. It also uses 15's I think, which gives a nice fast kick, three way system. Off subject.... Merry Christmas.

I stacked the subs in a way showed at number 4. I think I should have gone with number 1 for some reason.
What benefits are there having port down to ground?
Next time Im playin Ill thin more about the spot where I put the system...

I've used 1, 3, 4 and 6. 4 and 6 have more sub bass in my application, 4 and 1 more height so used more regular. 3 had a louder over all bass (might be cause of the size of the room)

if i had 2 boxes id do it as shown in fig 3
if i had 4 or 6 id stack it like fig 6
if i needed more than 6 boxes id bring scoops!
lol

Dont forget the kicks 'cos the scoops honk like mad above 90hz and are too slow for electronic dance, there you go, just as many cabs after all.

Yet even though they will be no good to me, I am sitting here looking at the many Scoop plans I have trying to decide which ones for the summer project, sort of infectious damn things.

Ive been using number 1 a lot. Kinda just got stuck to doing it like that every time
Id like to test number 3 but dont want midtops on sticks.
I need to test number 4 too again since I only tried it once and had other problems with the sound since it was my first session with the system.

Does reflex also go lower when "mouths" are together like in horns? I thought it was only on horns.

The reflex concept is to offer the desired
frequencies you are aiming for in a singular cabinet. The lowest desired frequency
is based on your design objective. Using multiple reflex cabinets (4, 8, 16, 32
cabinets) will increase the overall frequency response from a dB perspective.
As
the reflex has the capability to offer the flattest frequency response than any
other design on the market, you will receive a dB response like what is listed
below once you start adding more boxes in the equation.

Notice how consistent the dB level is within
the 100 Hz – 26 Hz range.
Horns can extend their frequency response
when having their mouths coupled together however will reach their cut-off
limit as the length of the horn dictates the lowest frequency point. As the majority
of the horns on the market today offer a short length, it is precisely this
reason why 98% of the homemade bass horns on the market take a nose dive below
50 Hz no matter how many boxes they add to the equation.

Convection due to coil assembly heating the air in the chamber, hot air will rise and exit at the top, cool air will be drawn in below, it works, tested on a regular basis in my living room using the wood burner.
