Has anyone upgraded the crossovers on Spatial Hologram M4 series loudspeakers?


If so what components did you use, by brand name, and how did it change the sound of the speakers? Also, any other mods you might have done, and the change it made in the sound?

I try to approach speaker mods beginning with simple/cheap, and  progressing to custom-designed/built crossovers.

The quality of cabling and connection methods is often overlooked -- even by reputable crossover upgrade services.  Short wire lengths matters.  I like to use the same cable as the customer is using from amp -> speaker (because they already like the way it sounds).  Sometimes bulk cable is not available or very difficult to work with.  In this case, try to obtain something "similar" in design, materials, etc.  Bypass any spades and lugs and connect directly via silver solder. Persnickety?  Yes.  Audible.  Definitely.

A while back I was introduced to the concept of balanced/floating crossovers by one of the most successful speaker companies of the last decade.  Developed by a German speaker engineer and now used in the flagship models of the company that introduced me to it.  It is a VERY simple concept that improves detail, focus, dynamic contrast, etc.   I incorporate this design into all speaker upgrades.  If you'd like more info, I'll be happy to explain in further detail.  IF your speakers are 1st order, this would be easy to deploy.

@waytoomuchstuff, I'm assuming @helomech knows what he's talking about on the speakers having a 1st order crossover. Talk to me about you implementation of the aforementioned crossover design. Am very interested. My goal is a great soundstage in which the speakers disappear. The current Spatials don't quite get me there. I know there is more and better to be had, and am considering a GR NX-Studio as a replacement. Danny is within driving range, so I can get a live demonstration. Just thinkin'....
