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

Well tks all for hints

I understand that would be better to measure how loud im listening… but i never did, just follow my ears… anyway i will give a try to install an app in my iphone

also i will try to use the sub out of my node and cut the lower frequencies to the main L/R out… in this way at least i will avoid the double conversion in an external minidsp

((“Cut lower freq to help my bookshelf speakers”)) As stated in a previous post excessive excursion in the woofer causes a dramatic rise in distortion which a properly adjusted high-pass could solve. You could use the Vandersteen M5-HP which is part of their sub-woofer system to do this. This is also a problem when adding sub-woofers to any system because ideally the main speakers should be high-passed to lower distortion in the main amplifier,and lower modulation distortion in main speaker’s woofer and cabinet when hi pass is properly adjusted you will easily know it.

There is not much music below 30 hz. Search frequency ranges of musical instruments. The Schiit Loki let's you trim 20 hz. I found it very useful gr8 waking up my systems when used light handedly. DZ

Well based on the SVS1000's, I would say the OP is not really into high end, although the Dynaudio's are pretty good. If you don't want to spend a lot of $$, try the route of reducing the low frequencies to the Dyna's with some type of high pass filter, NOT an EQ. If you want big sound and volume, you will need bigger speakers.

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.
