Kef vs Definitive In-wall for HT

[teloiv]

I am building a HT system and will use in-walls. I am debating between the Kef Ci9000ACE and the Def UIW RLS II for use as L/C/R. It is impractical to test each of these in my system before making a decision. Does anyone have an opinion between these two? The Kef costs nearly 2x the Def.

 

[AcuDefTechGuy]

Yeah, I'm going with KEF, Revel, JBL, Infinity, or Pioneer.

 

[monkish54]

I'd go with the KEF over the DEF any day.

 

[AcuDefTechGuy]

I like Def Tech, but they get absolutely no respect from a lot of people, which hurts resale value. KEF & Revel will hold their value for sure and probably sound better.

 

[monkish54]

It really comes down to the fact that the KEF is a point source and the Def is not. The KEF will be easy to place and easy to deal with once placed. The Def will be a pain in the *** because of all the constructive and deconstructive intereference.

I've heard some Def Tech ceiling speakers and they sounded great from any position/ location in the room. The sound was crystal clear. And with subwoofers, the overall sound was pretty great. So all that point-source theory is great, but how they actually sound is another thing.

I still don't recommend Def Tech speakers, though.

I don't think an anecdote can disprove a scientific/mathimatic certainty. *

That said, the CTC is very close so the effects will be minimal. With the point-source the effect will be almost nonexistent.

*I hope that didn't sound snippy.

No snip taken.

Proven physic/ mathematic theories are difficult to disprove.

But the human physiology of how an individual cerebrum interprets any stimuli (including wave & sound propagation) is not physics/ mathematics.

Take that.

Physics + Physiology = Grey Matter.

Got to agree here... I recently heard some Def Tech RCSII in the ceiling speakers and they sounded pretty darn good. They had 6 of these around the ceiling and they were using 2 HSU VTF-15H subs. Not sure on the center. I say it all depends on the installation and this guy has got money to have it installed correctly.

If they sound great, then they sound great.

I think some guys (like young Engineering students with their whole lives ahead of them ) try to see things very black & white , such is the case with physics and mathematic equations. They may talk about how sound waves interact and propagate to produce sounds. It's a great start. It may get them pretty "close".

But they forget that individual cerebrums will interpret these wave interactions differently.


As an older guy in the medical field, I'm more into human physiology, which can be quite grey.


Like how we interpret colors differently. We interpret sound, taste, touch, and smell differently.

Guys, I'm not really drunk here. Really I'm not.

Your still young... As a old guy "retired" from the telecommunications and DOJ field, I'm more into "heck with technical" , how does it really sound which is quite black & white and heck with color, I'm color blind.

Wait a minute now. That's not quite fair. The OP asked me (us) which speaker he should go with. Telling him how I like it (I've never heard it) would be pointless as we all have different cerebrums. If he wants to know exactly how it sounds..he needs to hear it. I can tell him, however, which speaker will be better from a technical standpoint for his situation. This is all I can do. **

If you two both liked it, obviously you were at the right distance, the dips and/or peaks didn't bother you much, or the reflections smoothed out the response a bit. *shrugs*

**To be fair, I am very technical and analytical in most things I do. I wouldn't say I look at things as if they are black and white, however. If I could, I would factor in how his cerebrum interprets sound and tell him exactly how it sounds to him, but I lack this ability (and a MRI machine.) It's not that this is black and white, but that I lack, and will forever lack, a significant variable. I can only solve part of this equation.

oh no you lack the knowledge given to mortals by the gods ( just finished watching Ancient Aliens) to analyze sound and it's structure. , and it's appears AcuDefTechGuy has been given the gift
PS: I have access to a MRI machine,but my knee will be in it for the second time.

That's no good! Doin' alright Cpp?? a horrid meniscus tear, and it appears since my surgery to repair that, my adductor mangus muscle could be torn hence another visit to the MRI....

All this talk reminds me of that Engineering joke I heard when my major was still Engineering. Something to the effects "A guy walks into a brain shop to buy a brain...the PhD Brain cost $1000...but a Dumb Brain cost $10,000.."

Why? Because the PhD Brain w/ years of life and experience is "USED" and the Dumb Brain is "BRAND NEW", young, and full of life!
