Speaker upgrade

+1 for @audioman58 comments. But would expand that to almost all speaker use cheap crossover parts. Unless the OP is an equipment junky and likes change for change, they may want to consider upgrading the crossover parts first in their current speakers. 

Have not seen any speaker manufacturer who uses the best parts, They all cheap out at some point even the brands well into 5 and 6 figure territory. 

@ronboco , I completely understand. I was in the exact same boat. But before you can determine what is used, you have to understand what good parts are for a crossover first. I have owned the Aviors and have owned several pairs of Wilsons. They all use decent but cheap parts. They are OK parts but far, far, far away from the best parts. 

Once you hear a speaker with copper foil caps, Mills wire wound resistors and high quality inductors your jaw will drop. 

BTW, don't take my word for it, pull a woofer out and take a look at the quality level of the parts used. Then sum up those costs, not very much considering what the retail cost is.  

@helomech, first you have educate yourself as to what the best high quality best performing parts are. Once you comprehend this, and know how to recognize them, then as mentioned before, don't take my word for it, pull the woofer out and take a look for yourself. Do you see copper foil caps int their crossovers? No. Do you see foil inductors in their Crossovers? No, Do you see Mills wire wound resistors in their crossovers? No.   

Agree, Rockport and others spend lots of time selecting parts for their crossovers, but they are all inexpensive parts. Sum up the total cost of these parts, and it may surprise you.

Why not offer a model with the best parts, At this price point folks would pay more for what they completely unaware of what they are missing. 

Once you hear the same speakers with the ultimate parts, you can't go back. 

@helomech, yep completely understand. Was the exact same response I had when another person mentioned it to me. 

Very few of the top speaker manufacturers use the best parts. Sonus Faber on some of their top models has just started. If you look inside the latest models from SF, you will see a better level of parts. On their less expensive models, they still use pretty inexpensive parts. 

A good friend of mine has a pair of Maxx 3s, They sound pretty good stock, but he built an external crossover out of the best parts, copying the original. Once you hear it, really tough to go back. Better imaging, better soundstage depth, better microdynamics, less smearing of the sound. 

An iron core inductor has so much hysteresis it can't compete with an air core inductor let alone a copper foil inductor.
