What makes an expensive speaker expensive

I have been searching and researching speakers for the last few months to replace my Paradigm 5Se's, which I've had for something like 25 years.

I probably don't watch my dollars as closely as I should, and when I was looking at some Triton's in the $2,000 (CDN) range, it didn't take long for the salesman to start talking "deal".

Price is important, but I like to think of price as a flexible range and understand what my options are within that range.

I also find that "marketing" encompasses many different things. Sure there's the hyperbole but the information presented can sometimes be helpful. What I find most frustrating are speaker companies that have so many different products, all priced very close together, and provide no clear idea of how they differ except for their price point.

Speaking of crossover parts, it is easy to take an inexpensive low and mid grade speaker to a much higher level by just replacing the caps, resistors, and inductors to higher quality ones.  I've done this to 4 sets of speakers over the years and have had wow reactions afterwards.  

Speaker companies have relationships with capacitor manufacturers for their supply chain.  For example a high end capacitor manufacturer such as Mundorf supplies all the caps for their entire line. The top product could use their oil/silver/gold caps that would cost a normal person like you and me $100 each but are sold to the speaker manufacturer for a little over cost at $20 each but the manufacturer also buys the cheapest Mundorf without any branding for their lower products in much larger volumes.  These relationships are made over years and even decades.

While I agree 100% with audioman2015,  I want to caution anyone about replacing Inductors.... Each inductor, yes has a inductance rating in henry or millihenry, they also have a resistance rating... For those that don't know,  a speaker may be crossed at 6db per octave at 2500hz,  but when you change the inductor,  if you do not compensate for the impedance change in the inductor itself,  you have effectively changed the crossover slope or point or both.  So for those that want upgrade,  that's fine, but unless you are capable of these measurements, I would recommend against inductor changes..... ESPECIALLY going from a cheap steel, iron or ferrite core to an air core... these resistive values can be dramatically different. I hope that this is helpful.

timlub - I completely agree!!  Resistances need to be compensated for the inductors.  There are plenty of crossover calculators online and measurements are always useful if changing the inductors.  If there is a drastic change in the crossover point, it could damage the drivers.  

A friend of mine has a pair of some vintage Sonus Faber's and the tweeter was using an electrolytic cap for filtering!!!!  We changed it out to a low end and inexpensive  film ClairtyCap (~$5 each) and his eyes nearly popped out of his head and realized the full capability of the tweeters.  It was like a switch was finally turned on!

Hi audioman2015, yep, recently recapped some old Kef's for a buddy,  same scenario,  he fell over.
