How good is the crossover in your loudspeakers?

"He is a hater and a shill.  At best his kits offer small and likely inaudible improvements." 
noone would do it if it was "small and likely inaudible improvements." an absurd comment and illogical 
OH SO negative ! you have not done any research on him and read any reviews ! 
er NO you sound like the hater! and he is no shill i have worked w/ him on several projects and the speakers had dramatic improvements NOW they were worth keeping and listening to! even cheap speakers !  
I think you have no idea how cheap the parts in many speakers are! some speakers even expensive ones have NO crossover only a couple caps to protect the tweeter or mid and they are running them as essentially Full range speakers! so even a modest price crossover yields DRAMATIC results! I have seen , heard it ! 
IF you were objective and fair you would listen to the before and after and watch some of the videos! ,but you are not are you ? so not worth it wasting breath to refute you really ! sad .

I am not negative about him. I just asked questions. For years I have used Audience 1+1 speakers especially because they have no crossover. My ears are sensitive to the negative effects of crossovers. Before that I used a Marchant active crossover. I couldn’t enjoy my then speakers with the built in network. Now I am using Raidho td1.2 and am happy with their crossover. I think this gentleman is doing a good job. I don’t think I need his service at this time though. Have a nice weekend. 

Like some others here, my current main loudspeaker---the Eminent Technology LFT-8b---employs a midrange driver (a push-pull planar-magnetic design) with no crossover in it’s passband: 180Hz to 10kHz, with 1st-order (6dB/octave) high and low-pass filters at those frequencies, handing off to a sealed dynamic woofer for frequencies below 180Hz and a ribbon tweeter for 10kHz up.

For those who want improved bass response, the Rythmik Audio/GR Research Open Baffle/Dipole Servo-Feedback Woofer (unlike all "normal" subs, it may be used up to 300Hz) may be used in place of the LFT-8b’s stock woofer (the LFT-8b includes dual pairs of binding posts, one for the woofer). Magnepan has been working on their own dipole subwoofer for a few years now (Wendell Diller has long insisted that non-dipole subs "Do not work"---Wendell’s exact words---with a dipole loudspeaker). Magnepan owners: no need to wait for it!

The OB/Dipole Woofer includes a plate amp that provides all the controls the Eminent Technology LFT-8c does (the 8c uses the same planar magnet-drivers as does the 8b, but a dipole---though non-open baffle---woofer in place of the 8b’s monopole), but operates in the analogue domain. The 8c operates digitally.

I had a set of very nice speakers that were also offered in a "reference" edition (for an additional $900.) Curious about upgrading them, I spoke with the manufacturer who advised on the components, and I replaced the caps and resistors with parts costing $450; these were the same brands as the ones int he upgraded model but much higher in quality. I didn't hear a significant difference. 

And then there's Wilson Benesch who run their midrange directly coupled to the amp, i.e., no crossover, and use primarily first order electronic crossovers or acoustic crossovers. 

The best crossover is no crossover, followed by an acoustic crossover.
