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

Yes high passing your speakers will make a big difference. The mini dsp is a good place to start as it is cheap. I would try 60z-80z. I think it will give you want you need as long as long as you sit 10’ or less.  Assuming that you are with stand mounts.

You can use an analog crossover or DSP to reduce the low frequencies to your Dynaudio speakers. High pass filter set to 80Hz. or higher. I personally like analog with a steep 24 dB/octave slope, but digital high pass is much cheaper. You won't be able to get the sound of larger speakers, so don't expect that, but should clear up the bass by reducing cone excursion of your 8" drivers at higher sound levels.

Using subwoofers without a dedicated two way crossover is just a cheap and very inappropriate path into subwoofers. Not only is your woofer bottoming out but before it does it is severely distorting everything else it carries.  Either get a digital preamp that has bass management such as the DEQX Premate or get a digital crossover like a DBx Driverack and totally bypass the analog and very poor crossover in the subwoofers. You will not believe the difference.

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.
