So It`s Ok To Mix and Match Ported and Sealed Subwoofers ??


I`m completely set on adding 2-4 more subs in addition to the one I have now.

Seemed the concensus was to either run ported or sealed not both.
In a music only system like mine the vast majority say to go sealed.

I now realize that the Original Swarm uses ported subs...somehow I missed that part, so there goes the sealed only for music idea !
Then, I see where in a room like mine I might be better off using a mix of ported AND sealed.

My room is about 20' x 17' with a slanted vaulted ceiling 12' at the peak.
There`s a hallway at the left corner on the front wall and another hallway on the back wall in the corner.

There`s a set of double doors to the left that open to a family room/kitchen area. . The double doors are open at the top so it`s not a sealed room.

 So...IS IT ok to mix ported and sealed then ?

Excellent, from what I've read, the HSU ULS-15 mk2 are a very good choice.


They are very good. :) Monsters in fact.
This article does a good job of critiquing approaches to a bad room:

But if you already have effective bass traps, open walls, and have an effective EQ stratejy, such as room correction, you don't even have to have 2.
As I understand it, the thinking of 4 subs is not about volume but room integration.

It's not a terrible approach, but IMHO among the most wasteful. With a good room, precise integration, even 1 sub may suffice.

It is the "precise integration"  that troubles most people, and a reason for the 4 sub solution. It kind of eliminates the need for so much measurement, alignment, etc. The Anthem, JL and Dirac systems do an amazing job of measuring and calibrating this for you, far better than previous systems, IMHO.

Also, if your current speakers are ported, plug them before subbing.

As if integrating the subs into the room and to your current speakers, you now want to add a significant and bigger new dimension.

I would suggest rather than going your current route:

  1. Get your room appropriately treated.
  2. Get 1 or two identical subwoofers
  3. Use the room correction in the subs or in a pre like the new Anthem lines to integrate the subs with your existing speakers for you.

It is quite possible that the room openings will severely improve your overall bass smoothness, making the necessity of multiple subs unnecessary, and that with precision settings you can get to done easily.

Best of luck,
