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

Aurgolo, Connect the outputs of the LS2 to the inputs of the minidsp. Connect one set of outputs of the minidsp to the Mark Levinsen and the other set to the subs. If you hear any signal degradation from the subs I will be both amazed and impressed and any signal degradation you might get going to the Mark Levinsen will be substantially less than the improvement you will get from the Dynaudios when they no longer have to reproduce those low frequencies.

Connecting both the Mark Levinsen and the subs to the minidsp will give your better options for dealing with any potential phasing or timing issues between the subs and the Dynaudios. Also the minidsp should have better e.q. options than the Loki.

Aurgolo, you place the minidsp between the pre and the amps because that is how the minidsp is designed to work. I think that you will get more sound degradation using the Node2 not to mention possibly greater phasing and timing errors, but give it a try and see what happens. You may like the results.

Also, if yogi boy is correct and the SB1000 has high pass filter capabilities that would be the easiest way to go. Connect your pre to the SB1000 and then connect the SB1000 line outs to the Mark Levinsen. The possible down side to this is that an 80 Hz, 12 db/octave crossover point may not be high enough or a steep enough drop off slope to alleviate your over excursion problem.
