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


Andrea

MC is on the right path, even if you equalize and limit the low frequency to the speakers, you will just turn it up more and be right back where you are. Little loudspeakers just don't play large and loud.

"....You cannot wring blood out of a turnip..."

This is the key point. The loudspeaker designer already got everything he could get out of the design they produced. The idea that you can equalize a loudspeaker system into doing something it just can't do will just make the problem worse. Subwoofers are not very good woofers and the heavy stiff cones and low frequency cabinet/driver design will not do a very good job trying to be a 3rd way in your loudspeaker system. Equalizers and crossovers can only do so much and they work best when you are cutting gain, not trying to add high energy frequencies outside their operating range.

As MC kindly pointed out the OP has his back against the wall and is still trying to push the wall harder. In audio, when you get to this point you have to make BIG changes. Big loudspeakers and big amps, there is no way to fine tune a system that just isn't designed to do what the OP wants to do.
