Question the Fritz speakers value because the Philharmonic are way low at $2k?
I do not know the parts cost for Dennis's products.
Fritz Revelator from scanspeak is $320 and the S/B acoustics tweeter is $409. the tweeter. So you have $1,400 in just drivers.
The XO parts-who knows $200? The Boxes $500. $2,100. Most big names then use a factor of 4-5 $7,600 to $9,000k. Fritz MSRP is $3,700. Steal them used for
$2,200 or $200 over cost.
That is value.
