I built the lx.mini cover last year to use it with my Spatial MT4’s. I alternate between a pair of diy Ripole sw’s using 12” Peerless woofers and a Vandersteen 2w. With the 2w the xover is set at 85 hz with a 6db per octave slope for both the low and high frequencies. The blend is very good and produces a very natural bass albeit being monophonic.
With the Mini dsp I can change xover frequencies and slopes and get fairly good sound. With the LX I set the xover at 110 hz. It really works pretty good also. Not as a low response as with the 2w though. The 2w gives more of a taut response, having a q of 0.5. The Lx results in a better sounding system that the mini dsp provides; more transparent and refined.
But, ... here is my question: Why do I have much more volume range for the low frequency with the mini dsp than with the LX? With the mini dsp I can get the sw output to sound much louder.With the LX the sound level range for the bottom is more limited.
The amplifier used for the sw’s is the Crown 1500 which has a volume control. The LX volume pots are set to their maximum. Thanks for looking.

If we are referring to the lxmini crossover that I published last year, then
it's not difficult to figure out - the low frequency stage doesn't have the
gain you want. The gain curves needed at the output of the power
amplifiers shows a +12 dB at the bottom, of which about 5 dB is provided
by the bass boost of the crossover.
The rest has to come from either gain differences in the amps or by about
7 dB attenuation in the high pass section of the crossover (assuming
equal gain of amplifiers).
