Jbl 4367

I just got them setup today. I think will move them around a little later. For now there three things which stand out:

1. They play loud. But if I didn't have an SPL meter next to me which I've used with other speakers, I would not really know how loud. They play loud without any edge or harshness. It's just pure and clean big dynamics. Just like a live full symphony would sound in the first 15 rows or so. The dynamix make live music sound very realistic. The wide dynamics also translates outstanding low level details. I think 94db sensitivity is being too conservative. I'm not sure how Harman reports that spec, but my guess would be closer to 100db sensitivity. Let's just say I don't mess with the volume much and find myself listening at 95db+ at MLP. I don't drink anymore but it reminds me of when I discovered vodka. I got drunk for sure but I really didn't know how drunk until much later on or even the next day. It just creeps up and up and up on me.
2. Midrange clarity, coherence and articulation is very Quad-like. I know to some that's like a backhanded compliment. But to me it's the highest praise. I think the special compression driver is a real hit. There's no crossover from 800hz to 40khz. Midrange magic is there in spades.
3. The highs are very extended. High frequency and especially piano and horns sound very natural. I'll prolly play with toe in and placement a little. Right now they point directly at the ears. They have a great sound stage even in the off center seats. The off axis is very good.

Huge congratulations Michael. Thank you so much for the update. Now I'm seriously interested in these speakers. I bet they are wonderful.

Sounds all good have you owned compression drivers/horns before?

Thanks. Yes Joe, you should check these out. I know you like quads also. I'd say all the more reason to check these out. They are unlike any other speaker I've had in my room.

Now you're getting "horny" ?

dallasjustice · Jan 30, 2016

Keith,
I know you like speakers with a digital crossver for valid technical reasons. My questions for you to ponder:
What's better, a speaker with a few well designed digital crossovers OR a well designed speaker with no crossover in the critical listening band?

That is a really good question. Where do they cross over?

Michael Hi, interesting question, I believe that our Cessaro 'chopin' two ways are crossed around 800Hz into a TAD 2001compression driver which is designed for mids and HF.
I have the Grimm Ls1's next to the Chopin , I can't honestly say that I have heard any artefacts from either 'crossover' ,there are other aspects which are far more evident for me ,usually room related.
I have always believed a well designed three or four way loudspeaker is perhaps less compromised, I prefer our 'Liszt' four way horns to the two ways, but the Liszt are full range 20Hz up, they are physically taller ,image is larger , I don't know what are you finding?
Horns can have a very beguiling presentation ,an effortlessness and they don't have to 'honk' although many do.
Do you notice any difference between the character of the horn mids/HF and the reflex loaded bass ?
Very Best,
Keith.

I can't honestly say I can hear any hand-off discontinuity from the waveguide/compression driver to the woofer. I need to listen more though.

The other great thing about the waveguide technology Harman uses is the off axis is great such that the image remains very good for adjacent listeners.

Please do keep reporting I am interested to hear your thoughts, are they very different from the Giyas?
Front loaded bass is really superb, but on the large side!

Wow!

I had a gut feeling these would be special. I know everyone's taste is different, but your description of the JBL 4367 seems exactly what I'm looking for in a second speaker. I do love that Quad like sound, but do not want to deal with any of those speaker downsides. If I can not hear them locally, I may just order a pair.

Thank you again.

Welcome to the well executed horns club. I love the dynamics for sure. But over time I've come to realize that there's a "transparency" and "see through" quality delivered by those dynamics too. It's analagous to adding great subs: yes, the low end improves, but surprisingly, so do the mids. So too with great horns: yes, the jump factor improves, but so do the transparency.

Yes, it's the dispersion pattern not being as wide as conventional dynamic speakers... the increase in the ratio of direct:reflected sound makes for less smearing of fine detail.

JBL's wide-dispersion horns/waveguides are interesting... not sure I agree with it so much for pure audio but it makes a lot of sense for theater where there are many seating positions. For audio though, no matter what there is only one sweetspot and I'm not sure the wider dispersion is ideal for a single listener. But this is mostly personal preference at this point.

That's what I did. I just rolled the dice.

Thanks for putting it so kindly. I thought I was a home theater enthusiast earlier today. My buddies are already making fun of them. I've got thick skin so I can take it.
