Hi sifus, does anyone know the latest pricing for Velodyne Impact 10 and Velodeny CHT-10r subs?

And, is it cheaper to get from Desa?

Thanks

I saw quite a number of sub at Desa loyat so many different types & sizes to choose.

Wah...U found your way there ar?
Did you found A&L also?

Ya! He! He! Tq for ur direction I poke in to Loyat & Sg wang. Visit CMY, Desa, Tong Lee & A&L. Got back with KEF & Mission spk catalog & Onkyo 2009 catalog.

Catalogs only?! Taukeh, I thought you are on HT shopping spree here. Coming over for sub?

Actually I want to try out the Klipsch sub but didn't find it so just look see look see only. Beside the biggest sub I saw only 12", I am hopping to try out 15" sub to compare against my Paradigm 14" to see which one more BOOOMMM!

Also want to shop for surround spk.

Soon, you will see a few Klipsch owners here. Once audition, I guess there is no turning back for them.

Hi all, hrm..anyone ever tried making a car sound system for PC? O.O

I think the CHT-10R has been superseded by the CHT-10Q.

Promised to update the charts of the difference between the phase setting on the sub. As mentioned my sub is rated at 26 Hz +/3dB. The measurement were done using the software, a usb sound card and a tripod mounted radio shack spl meter.



Sub and mains sub setting phase 0



Sub and mains sub setting phase 180

Nothing was changed in between. The phase setting changed the response of the sub + the room. Setting the phase to 0 brought my sub response to about 21 Hz. But there are other drops elsewhere (ie, 55Hz). The response at phase 180 is better and less wavy.

I will try to post some other charts when I move the sub around.

I have a peak at 37Hz that I need to tame. Need to move the sub around a little. Also there are other charts to confirm if the problem is with the sub or the mains. That 37Hz peak is caused by the sub and not the mains. The ideal target would be to maintain +/-5dB from 75dB. Next the sub+main charts but this time thru the onkyo avr using stereo mode. This engages Audyssey. As you can see the Audyssey enabled the sub to go down as low as 18Hz and tamed the 37 Hz peak.



Sub and mains thru AVR (pre-amp, front out to integrated amp) with Audyssey

Audyssey definately does a good job. But the experts advised that for music I should not let the signal go through 2 pre amps. It is ok for movies but not so for movies. It is a good tool to understand the effect of your speaker and sub adjustments. So I need to move the sub and see if I can remove the 37Hz peak for my music. Also will repost when I get the Galaxy Audio CM-140 and remeasure.

Thanks to bro mys_terious for loaning me his RS SPL meter.

Thanks for sharing the response charts. really informative.

check with you again anfieldude, I would assume that the RS SPL meter has a minijack output, and it is this output that is connected to the line in of your soundcard?

In the software, you are able to set the time interval (time for SPL meter to settle) between generation and sampling the reading from the SPL meter?

From the charts, it has quite a good curve, are you sweeping with 1Hz resolution?

Yes on the RS meter or any SPL meter you need to have a line out and it needs to be input into the line in.

Yes u can. For now it is done automatically.

You know thats a good question. I sweep from 2Hz to 200Hz or for full range until 3000Hz. Just checked the raw data it seems to be at a resolution of 0.4Hz.

Its a pretty cool software. PM me if u need details.

Thanks for posting the charts. Quite informative.

anfieldude, I have the software (dunno where I chuck it) and SPL Meter. But never put it to good use

Maybe I need to take a day off from everything to focus on this calibration.

Check it out. It only takes me about 20mins to run a few tests. At least you will understand if you need to move around the sub, mains or improve equalization. Also will help if u want to do some room treatment.

last time, i plotted my chart manually.

bro, can pm me the name of the software you used.

that is so true.....

The difference is only built-in LCD and for higher price in 10Q

The 10Q also has auto configuration. Just like the YPAO i guess.
