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

For example if i use a minidsp 2x4 in the between the audio research and levinson... will it work or not?
Yes, that will work! Your dynaudio special 25 can play louder and cleaner with the help of a high pass filter. The svs 1000 can go up to 270Hz -3dB which is a good choice.
Apparently no-one caught on to the fact you have two SVS subs.

Probably the simplest option is to connect the pre output to the SVS and connect the SVS rca output to the ML and fro, there to the Dynaudios. Start cutoff frequency at 80Hz and take it from there.

Your solution 1) could work with a parametric equaliser, but it might adversly affect the sound quality. Good luck!

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.
Tks everybody for the suggestions

@gregm ... i also thought about the rca out of the svs... but the manual says that those are to connect several svs in line... so im not sure that it is a high-pass output
Even if i can mamange to use the rca out as a high-pass filter im not sure the quality is aligned with the rest of the system

@diones51... the 2x4 HD has a DAC which i dont need, so why not buy just the 2x4... i think thay are the same 

Also why use the 2x4 to pilot the 2 SVS?.... they have a good DSP and iphone app which is very flexible (6,12,18, or 24dB slope, volume, phase 0\180, and several presets in memory)

Im just concerned that the minidsp could somehow degrade the overall quality (im old school... the less you put in the music path the best you get)


@imhififan ... yes im sure it will help, im just worried about the potential degrade of the sound (see above)
Both the 2x4 and 2x4HD use the same DAC the difference is the better DSP engine.
