I'm trying to come up with a sub that will fit under my desk and mate with my LGK 1.0's. It would be nice to have it play down into the upper 20's but lower 30's would be acceptable.

Since this system will be playing while I am working and the sub will be almost literally sitting at my feet, high SPL's are not needed. A small footprint is. A single 8" driver would be fine except that as I understand it, the HX580 amp must have two drivers, one for each module.

The HX300-12S says it is for driving one 12" or 15" driver in a sealed box, I wonder if it could be used to drive one DS800-3 driver in a sealed box. If so, I could probably cut the internal volume down to 0.7 cu ft. That would fit in a 12" cube made out of 3/4" material which I could fit under my desk.

Am I on to something here or way off base?

Mike
Check in our website for the M7 CI Kit: http://www.rythmikaudio.com/DS800ci.html

With that CI Kit you can play down to 30Hz with a single DS800-3 driver and HX300 amp.

The 11 dB output advantage around 16 Hz in 2-port mode should produce a very noticeable difference on movies imo.

The only thing that is not 100% accurate is the output, which will be a little bit lower for people operating their sub(s) with the limiter engaged.

The charts help a lot in making decisions, and comparing modes and subs. Also talking with Enrico over the last few days, I have pretty good plan in place!

I know they are accurate, but what I am saying is that real word listening in a room most people probably would not be able to pick out distortion unless they are pushing their sub(s) to the absolute limits like Josh does. The servo technology coupled with an amplifier rich in features really helps to mask the possibility of poor sound quality. This is at least my experience when I have pushed my subs hard at times. I'm a big fan of what Josh does and often refer to data-bass.com for info.

I get that part too. I mean I have run my dual Hsu's in one port open and pushed the hell out of them, and they sounded good (6db hot).

You need to come down to San Antonio and bring your sub. I want to put this servo stuff to test/rest over some beers - a lot of beers. And wings of course

It's a load just pushing around the room at times when I have to move it. What did you end up getting I forget a V3600 right?

Sliders. They are perfect for moving anything. You'd be surprised at how much weight you can easily push with these.

So I think I got the mic and REW setup and when I ran my sweep it sounded like it came out of my laptop and not my speakers. Is this correct? When I click sounds in taskbar and click on mixer should it show my volume at 100% for the laptop speakers, Denon receiver, and REW. Is this correct or should I mute my laptop speakers?

Have u installed the ASIO drivers? That will make it easier to choose the channels to output to. U need to choose the output and input device in REW preferences.

U shd be able to choose to output thru hdmi(per channel) in REW preferences. Power cycle ur AVR after exiting REW and ASIO with the laptop connected via hdmi and see if the options come back after a new hdmi handshake with ur laptop and avr.

Did you select the correct hdmi input on your Denon where your laptop outputs to? Also, make sure play back device on your laptop window is set to Denon AVR as default sound card.

Thanks Enrico.

Is 0.7 cu ft enough space for a DS800-3 with an HX300 amp?

I did yes and playback device is the Denon. When I run a sweep it sounds like it's coming from the laptop and not the speakers. This isn't right correct? Do I need to mute the laptop speakers?

No, it is not correct unless you want measure your little laptop speaker FR, lol. Muting it won't help as REW will not get anything. Are you absolutely sure you go to your Denon menu and select the right HDMI input number? I assume you connect HDMI from your laptop to the front HDMI jack of the Denon. If so, it's HDMI 7? Simple way to find out if you had selected the correct HDMI input on your Denon and if your laptop HDMI sound card is set as default is to play a song from your laptop, sound will be on your Klipsch speakers. If not, something is wrong. Then disconnect your bluray player HDMI cable to your Denon and connect your laptop there, you will definitely hear sound from your speakers. Try these.

Then he can't run REW. Make sure to right click the sound card/property to see if anything is out of whack there. Also click configure on the sound card and then click test to see if audio is sent to speakers.
I am not home to do that. It will be the weekend. Sorry.

JT78681,

What is your mic and playback devices settings saying?

What are the settings on the ASIO4ALL settings saying?

Maranatz SR-7009, Oppo BPD-93, MTV 7000D, LG LW6500, aTV, WDTV Live, Harmony 650 remote, KEF E301+T101, MiniDSP(2x4), Emotiva 2xXPA-5 (Gen2), Rythmik 2xF12G+2xF8 (on order), HiMedia Q16 (on order).
