Mini DSP with Dirac or add another subwoofer

Setup is a 2 channel system with a subwoofer

Laptop - DAC Musical Fidelity M1- Aikido Tube preamp- Rotel 1090 power amp- Acarian Alon IV+Rythmik F15 subwoofer

Would adding another sub nearfield to the LP be better or would it be better to have Mini DSP+dirac as an upgrade

In order to recommend an upgrade, we need to know what you feel is lacking in the current setup, i.e. what is your ultimate goal?

More information about the room would be beneficial as well (e.g. total cubic footage, distance to listening position, treatments, etc.).

Improve tactile response is the target when watching movies. Room is 1300 cubic feet. Wondering if Dirac would help in that area or adding a sub near the LP would be a better approach

Thanks for the info!

Is the room sealed?

Without knowing the current frequency response of the sub, it is impossible to say if Dirac would help, while adding a second subwoofer near (as in directly behind) the MLP would guarantee more TR.

That being said, if you are mostly satisfied with the sound of your current sub and you are only looking for increased TR, you may want to consider a dedicated TR device (i.e. Buttkicker, Crowson, The BOSS).

Sub is 14hz +/- 3 db

2 windows 2 x 4 feet that opens to the solar system

Second sub would 3 feet behind LP

TR device not possible as I use an office chair when watching movies, couch is facing to the side of screen

I meant to say the in-room response of the subwoofer...is this the measured in-room response, or the spec from the manufacturer?

Depending on the sub you are thinking of getting, 3' behind the MLP will most likely add substantial TR. However, sitting in a office chair (which are usually fairly stiff and rigid), may not benefit you in your quest for TR. Are you on a suspended floor or concrete slab? Suspended floor will provide much more TR than slab....
