JA Perspectives VS Tyler Acoustics Linbrook Sig System

I have to say that looking at the latest measurements from the JA perspectives I am not sure if JA is applying his trademarked crossovers here. The measured impedance and slopes seem rather conventional.

This paragraph from Stereophile is curious:

Speakers from Joseph Audio's early days used crossovers featuring Richard Modaferri's patented Infinite Slope topology, in which a modest network (in terms of number of components used) produces high- and low-pass filter slopes in excess of 100dB/octave. The Perspective and the Pulsar, however, use what Jeff Joseph calls an Asymmetrical Infinite Slope Crossover set at 2kHz, which attenuates the woofers by about 41dB.

This does not of course negate the quality of the sound, or the value of the finished product.  I'd just be cautious about ascribing the end result to the Infinite Slope crossovers.

The Perspective’s crossover still operates on the basic principles of the patented Infinite Slope design — common to all JA speakers — with tweaks to the slopes for more optimized performance (this is paraphrased from what Jeff Joseph told me in person).  The crossover remains the key to the JA sound as the cabinets and drivers, while very good, aren’t anything unique or special. 

Very interesting, thank you gentlemen.

I love Joseph Audio and Tyler Acoustics.  US Audiomart has some Linbrook Sigs for $3500 which is an absolute steal. 
Crossover design plays a big role in how a speaker sounds so +1 Soix with regards to that.

I am a total Fritz fanboy as of late.  I would look into a pair of Carrera BE’s if I were you.  They are simply amazing!  

Hey b_limo, that's so funny, I just sent Fritz an email just a couple of days, his stuff definitely seems to be held in high regard. I was looking for a floorstander to achieve more bass. I presume subs would be a must with the Carreras? Maybe 2, maybe a Swarm? Lots of cabling!
I'm open...
