JSE infinite slope

HI! I have these JSE infinite slope speakers model #1.they sound wonderfull! but how come I do not see them in reviews.I know they are old,but they sound really good.I have seen the crossover"infinite slope"in the JOSEPH AUDIO speakers.I compared them with my friend's B&W side by side,his are brand new B&W speakers.he chose the music "classic,jazz,R&B," blind folded.HE went first!
-classic (He chose the JSE)
-jazz (He chose the JSE)
-R&B (He chose the JSE)
then it was my turn!.
-classic ( I went for the JSE)
-jazz (I went for the JSE)
-R&B (I went for B&W)
so it is clear that these speakers "JSE INFINITE SLOPE" can figth with the big fellas like B&W.well after we finished the blind fold test.He asked me where I got these speakers from.because he did not know the brand.I told him,from a thrift shop.now he is searching for these guys in "ebay" and "audiogon" he wants the same.three way ,piano finished.by the way HE paid for his B&W around $2k.and I paid for mines $40.00 in the thrift shop for the pair.not bad ehh!.I saw once. one pair of "JSE infinite slope speaker" on ebay,but they were ugly ones and
they were four way.mine is three way.one 1 inch soft dome tweeter,one 6 1/2 midrange,one 8 woofer.the shape is like a piramide from front to back."very nice"and the piano finished ohh my god! wonderfull.
so far I am so happy with these JSE.now I can listen to pure music like it was ment to be.well if you ever come across to a pair of these fellas just get them!!! you will be glad you did!.

- It is no coincidence that Joseph Audio references "Infinite Slope" in it's advertising. Jeff Joseph used to be a salesperson at Harvey Electronics in Manhattan in the 80's. Harvey carried JSE speakers. I believe he bought the rights to the Infinite Slope technology and utilizes it in his products. -

Your JSE 1 is not a three-way; it's a two-way. The bottom two speakers are both woofers. There is only one cross-over. The smaller woofer runs slightly out of phase at its upper frequencies to prevent the usual bump in the bass output. At lower frequencies they both work in phase.

Melm,

You are close, it is a 2 1/2 way, similar to what Canton does with their matched mids.

KennyT,

Sorry, but you're the one who's not close. The speakers operate EXACTLY as I describe. They are 2 way, not 2 1/2 way. The operation of the 2 woofers was a second development of Richard Modafferi used in the speaker (after the "infinite slope").
