JA Perspectives VS Tyler Acoustics Linbrook Sig System

I wouldn’t downplay the significance of the proprietary JA Infinite Slope crossover.  To my ears it gives the speakers a special sound that sets them apart, so I’d buy used Perspectives but that’s me.  The JA Profiles would also be high on my radar if buying new. 

I’d actually guess — and it’s just a guess — that the new LSA-20 (from Underwood Hifi) may sound more like the Perspectives than the Tylers as they seem to be doing some similar variable-slope type things with the crossover.  Since they’re sold direct they’ll be very price competitive as well.  Hope this helps, and best of luck. 

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...

I’m not so sure that you’d need a sub.  It depends on how big your room is and what kind of bass you want.  They wont rattle your windows but they play really low, like high 30’s.  They had ample, and I mean ample, bass in my room. Perhaps a bit too much actually but my listening room is 11x14 with 8 foot ceilings.

I’ve heard JA’s many times at shows and love them so I have a good reference point with which to judge the Carreras.  I’ve owned Tyler Acoustics.  Seas Excel drivers used to be my favorite until I spent some time with the Revelators, and I’ve always loved Beryllium tweeters. 

With some solid stands and placed correctly, with high quality front end components the Carreras are wicked good.  
I just hooked up his new and upcoming Carbon 6’s an hour ago and even with them brand new out of the box and my equipment being turned off for 3 weeks, I’m sold.  I have the Carbon 6’s for review but I don’t think they are going back.  I can’t wait to see how these little guys sound once they have 100 hours on them and my associated equipment gets settled again after being off for 3 weeks.

Fritz is a damn genius as far as I’m concerned.  His only downfall is how humble he is and how much he understates his products.  Talk about a serious case of under promising and over delivering.

If I can do anything about it, I will always have a set of his speakers in my home.

Here’s my review of the Carreras...

Here are some pictures of the Carreras I had in for review...

The speakers exude quality and they look better in person than in pictures.  Once you hear them, they look even better.  I’m not so sure that I like the “blingy” appearance of the competition so much anymore. If I were to buy some Carreras though, I would get a finish that had loads of character in it, even if I had to pay extra.  A crazy dye might be fun too as I haven’t seen Fritz do that yet and it would be fun to have a one off, custom made set just for me.

Awesome b_limo, thanks for the lengthy & detailed insight.
Erik speaks very highly, as do many others, of Fritz and his products
Moving so no room as of yet, doing my research beforehand.
Noted and shortlisted!

New and up coming Carbon 6? I see there is already a 7, is counting backwards?

No Beryllium tweeter though, he's using the ScanSpeak AirCirc or Illuminator Tweeter in the 7.

The Beryllium tweeter is used on the Carreras!

The Carbon 7’s use a Scan Speak “classic” 7” driver and they sell for $2800.

The new model, the Carbon 6 uses a 6” Rohacell / Carbon Fiber sandwiched SB Acoustics driver and they’ll sell for $2000.
