Raw curves on Roy's Cinema Products.

Recommended Posts

I am interested in seeing some curves on some Commercial/Cinema Products.

This is not an attept to challenge Roy but to see what this stuff does and allow some of us to make a decision on products.

Roy. Have you got some curves for the K510 with the K69?

If you get around to it: Curves on the KPT-884, KPT-684.......and the K-703. Gonna build a system sooner or later and some of these may be in it. No rush as I know you have others things to do at work than piddle with us forum junkies requests.

Thanks in advance Roy.

excuse me while i clear the cobwebs.................................................................................................................there.....

you're in luck. i got you the 69 on 510, 684 and 884 both freq and imp. look them over and see what you think or if you have any questions.

have a blessed day,

Easy to understand Roy.

Couple of things. That KPT-684 is an impressive product. Looks to me like that is good out to 600Hz. The impedance doesn't change much way out there. Very versatile. Not much EQ needed there.

The K69 on the 510 is "falling" some at 4000Hz. I need to think about that w/o EQ. With EQ...Do you basically do one of those 6dB shelfs at about 4000Hz.

The KPT-884 is a real house rumbler. Nice and flat to 125 Hz. Not much EQ needed there.

Roy. Very nice work....I know that isn't much coming from a non-pro but the info really does help me.

Worked with an Architect today about a new house. A slow process. The above may be used in a downstairs "dude room". Not really an HT room....but a stereo room for me. The HT room will be different.........more theater looking with some small scale reference products.

I'll need to look at this some more.

OK. Don't laugh...just....thinking...... I know that two KPT-684's in one room is rediculous. But that bass bin /Subwoofer is almost like an "LF section". Unlike subwoofer which peter out in the 100-200Hz.

What would be the problem with crossing the bass bin at say 500Hz and and basically making it a LF section.

you funny man! it's not ugly enough. put the 402 horn on top of that beast...to answer you question, nothing wrong with it. you see in the cinema, the lf section really does not need to go below 40-45 hz cause the processors automatically crossover at about 50 to subs. that is also another reason why we sell components and only offer suggested systems, so that people can mix and match to their hearts content.....you truly have a tinkerer's heart....

have a blessed day,

you can to flatten it out.....

this one was developed to go against a sub that used the aura 18" and we go into the battle to win!! if you know what i mean!!

thanks for compliments.

let me know if you have any more questions,

Hey Roy!

Thanks for the K510/K69-A Information and it's interesting to compare it with the K402/K69-A.

I notice that the Impedance curves appear to be pretty much identical.

I also notice the SPL vs Freq curves shows as expected that the K402/K69-A on axis response is up about +4db from approx. 600Hz to nearly 1.25kHz which I assume is the more ideal Polar Control of the K402 at play here.

The other observation is the differance in response from about 12.5kHz to 18kHz where by this plot the K402 looks a little smoother by several db also. Is this because the K402 Polar Angle is starting to decrease in this range versus the K510?

So with that observation I've got a request that I will e-mail you Roy?

Edit: Hey Roy,

I just remembered per my request in the e-mail that we would be comparing different drivers but it would still be interesting to see!

"what did you think of the polar data of the 510 and 402? and no don't show it to jc or shawn or deano and especially coyotee-o!"

Nanny nanny poo poo.. I have seen the 402s polar data. ;)

Wouldn't mind seeing the 510s data though.....

hey miketn,

The "Little Horn That Could" looks like to me!

Of course the Vert Polar is begining to widen at 1.2 to 1.5khz but it is a smooth increase all the way down to approx. 450Hz and the Horizontal Polar Control looks "very" good all the way down to 600Hz with a smooth widening to again about 450Hz. So I'm thinking with a crossover in the 600Hz to 800Hz range with the Jubilee LF section then I believe that you would have a very even and smooth sound and an excellent alternative to the K402/Jubilee and is definitly the way I would go if I didn't want the looks of the K402 on a Jubilee.

I also want to add that after hearing/using the K402/K69-A I couldn't imagine wanting a tweeter added to the speaker system and making it a 3way.

For Modifiers: If I had a LaScala, Belle Klipsch, Cornwall and wanted to try a different Midrange/Tweeter it would be a K510/K69-A combination for what I believe would be an excellent two way system and if you wanted to go a little farther then add an active Crossover with the ability for Time Delay and EQing the system.

lol

I too would like to see the 510 polars...and just for kicks it'd be cool to see the 400 as a reference point to a lot of klipsch products I've been able to listen to over the years.

Btw, JC...are those dual 15's or dual 18's that you're looking at for the bass bin? I wonder what their directivity is at around 500Hz? That would be insane to have in a dedicated listening room.

Mike B,

Those are dual 18" woofers. I don't know what their directivity is. I asked for that curve as I found it interesting that the specs on the cutsheet say 36Hz-800Hz +/- 3 dB. That sounds more like a LF section than a Subwoofer. The way I understand it.....and you can correct me since I know little of "Pro" stuff......is that is considered "subwoofer" as it goes well below 50Hz for THX Cinema specs.

http://www.klipsch.com/media/products/cut-sheets/KPT-684-SW.pdf

Anyway. You probably know my intentions as I still like the sound of bass reflex. So I am looking into the idea of having some "overthetop" bass reflex in my new house.

Why not use the KPT-684 as the LF section? Would like to know your opinion there. Forget the looks ....I'm.....trying to leave that out of discussion....hence more of the reason I wished for a "commercial" thread.

I have sent the order request sheet to purchase a pair of the K510's and the K69's. Will be a slow put together.

I posted the Raw K402 response curve because I was going to later ask some questions regarding the Parametric EQ setting to flatten out the response and tame the peaks. Read up on Parametric EQ over the weekend.

So is the K402/K69 EQ'd with a +6dB high shelf somewhere between 4-6000Hz?
