My setup with minidsp

My setup with minidsp - comment or post yours if you like

I´m a complete newbie with minidsp , so my first question is which xover filter order are you guys using ?

Crossover order is going to completely depend on the design. No single solution can work for everyone. Tell us more about your design and then someone can help you with the crossover.

active sub JBL es250p crossed at 110hz to Visaton GF200

GF200 crossed to Peerless HDS-134PPB ( at 250hz ?)

Peerless HDS-134PPB crossed to Fountek NeoCD1.0M ( at 5khz)

mids tube preamp , connected between minidsp and mid amp , i like the tube sound in mid frequencies mostly on guitars

Are you able to measure the speakers?

 

[lduarte1973]

not yet i dont have mesurement hardware , but it might be a bit tricky since i use 2 sets of speakers - 1st set - seas ca18rnx woofer , peerless mids and epos tweeter , 2nd set - visaton gf200 , same peerless mids and fountek cd1 tweeter

the dynavox amp feeds the tweeters , the ca740a the mids and the delta290 the woofers , the subs are active

probably i´m not looking for a flat frequency response anyway and my room is very difficult room to work with since the walls have no acoustic treatment cause the wife doesn want it

i feed the cd player via optical and pc analog

 

[lduarte1973]

my main problem is that i get some frequencys on voices and guitars reverberating in the room , problem is minimized if i cross from woofer too mid at 600 insted of 800hz but that might make mids sound too small (like coming from a little speaker)

 

[lduarte1973]

a work in progress but near the final results

 

[lduarte1973]

just a question , i´m running my tweeters without any protection , is that a problem ?

 

[lduarte1973]

i always turn the tweeter amp off before turning off the minidsp so i dont get that "thump" on tweeters

what do you guys think of this dac to upsample my mids to 24/192 ?

[lduarte1973]

I´m not getting this dac anymore , i bought a 640C cd player , will use it as my digital source and use the 740C as dac to upsample mids to 24/384

 

[lduarte1973]

ok i bought new mesurement gear :

Behringer ECM8000 Ultra Linear RTA Measurement Condenser Microphone Mic ECM 8000 | eBay

BEHRINGER PS400 Ultra-Compact Phantom Power Supply NEW | eBay

 

[lduarte1973]

my first mesurement with mic only , i´m still waiting for spl meter , what does this graph tell me ? from 10 khz up it´s flat and i´ll leave above 200hz i´ll deal with it later
