Cut lower frequency to help my bookshelf speakers


Dear All,

I try to open a new topic… which i did not find in the previous discussion so maybe is new to the most

 I have a 2 channels system which i want to improve with a minidsp or eq

the question in short is the following:

i love my dynaudio special 25 speakers but often i feel the need to have a better punch on the bass frequency

so i tried to add a couple of svs 1000 pro subs… with excellent results

point is that when i turn up the volume too much i feel the dynaudio midwoofer cone rattle when hit the lower frequency (actually the coil reaches the end of the air gap into the magnet)

so im thinking to add a dsp or eq to cut the lower frequencies before they reach the dynaudio

i have a pre audio research LS2 + amp mark levinson 23.5….. the idea is to add the dsp or eq in the middle and have the following configuration:


  1. connect the minidsp or eq. to the first rca out of the audio research (fortunately i have 2 rca and 2 din outputs) and then to the mark levinson …. in this way i could to cut all the bass frequency under 50 or 60 hz and have the levinson handle  the dynaudio 


  1. connect the 2 subs to the second rca out of the audio research and use the svs internal dsp with iphone app to calibrate them


Hope is clear… What do you think?


Better a miniDSP 2X4 or a Schiit loki mino+


Or anything else?



tks alot for any help or useful hint, best

Both the 2x4 and 2x4HD use the same DAC the difference is the better DSP engine. 
Up your budget a bit and get the minidsp 2x4 HD. Read the manual a couple of times until you fully understand it. You will connect your preamp to the minidsp input  and the subwoofers and amp to the minidsp outputs.  Your SVS subs don't have a high pass filter set the crossovers in minidsp.  I would also get the UMIK 1 with it and use REW but do that after you're comfortable using it. Integrating subs properly takes some time and knowledge so don't rush it and learn as you go. Don't worry about the minidsp degrading the sound you'll find it will greatly improve it once you're familiar using the software. Good luck.
Looking at Stereophile old measurements of the Special 25 I would try the high pass cross at 100hz then try 120hz if you still hear distortion.
