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!.

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").

Lanchile,

I was a relatively early purchaser of the JSE 2 and became friendly with the designer who updated it to what was known as the JSE 2a for me. I did a lot of research at the time and the JSE 1 preceded the JSE 2. The JSE 2 was a five speaker 4 way design that used exactly the same kind of 2 speaker bass configuration as the JSE 1. To my knowledge there were two other JSE speakers made in addition to the 1 and 2.

I recently replaced the JSE 2 speakers with VS 4jr speakers and I am very happy with the result. If you think the JSE 1 sounds fantastic, what more is there to add?

The only other thing I can tell you is that the 1" tweeter of the JSE 1 is a Dynaudio D 28 and the other two speakers could have been sourced from Madisound at the time and for many years thereafter. Now? I don't know.

JSE stands for John Solecito Engineering. John now has a different speaker company.

The first reviews of these speakers appeared in the Sensible Sound. The JSE 2a was reviewed in TAS by Mike Kuller.
