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.

I am using two ports on the VTF15 right now for headroom, and the FV15HP in 2 ports offers a good bit more power from 12-25hz.
The 11 dB output advantage around 16 Hz in 2-port mode should produce a very noticeable difference on movies imo.

I don't think those numbers need to be taken with a grain of salt...the output and distortion numbers are accurate and were recorded with the servo technology in use. 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

Like a honey bee beatin on my screen door, I gotta a little buzz and my head is sore.

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.

I just wanted to say, it cracks me up when I'm looking at a thread and see "Last post by Aliens".
