I see the specs for the 8" servo is up on the site! 

Will this possibly show up in a new speaker design?

I think this might be the latest info on new designs:

I remember hearing about these years ago, very interested to see and learn more about them!

There is definitely new stuff in the works.

Thanks for noticing the new info on the 8's. Unfortunately the retail price is a little higher than I wanted it to be originally. This is due to the drop in the value of our US dollar.

I have 200 more SW-12-16FR's on the way soon and the prices of those have gone up too, because our dollar isn't buying quite as much any more.

If you check the prices of the drivers over at Madisound or other places though, you will see driver prices across the board have gone up quite a bit.

Also note that Neo 10 info is up too. Unfortunately the price of Neodymium has gone up considerably (like 3 times what it was). So the cost of all of the Neo 3's, Neo 8's and Neo 10's have really shot up. I have adjusted prices accordingly.

I had to adjust the price of all of the kits that use the Neo tweeters to reflect the higher cost. So quite a few of those kits have popped up in price a little. Sorry...

I left the prices of the LS-6 and LS-9 kits the same (not on the web site yet) for now as I order those tweeters 300 at a time and still have good stock.

I'll post more info on the new stuff that is in development as more gets done.

No doubt.  Everything but my income.   

When do you think you'll be able to get some measurement data up?

Have a pair of the 8" servo subs on the way from Danny for an open baffle project.  Will be trying them with my existing servo amps from the Super-V's.

Cool......dont forget pics Hal....

I was asking in another thread about the OB sub section of the V2 for example being used strictly as a sub. I have the N3 in TL towers in a fairly small room and I was looking for a sub to go with them. To start with, I'm assuming that the V2 OB design requires the subs to be installed opposing each other for a reason and that you wouldn't have a left channel in one and a right channel in the other. So you'd have to have 4 of these with two amps. I'm thinking that would be a little nuts in my 9 1/ x 16' room.

But these 8's might be just the ticket! I have a question about the "W" design. Why is it done this way and would just a single plane baffle not work in this type of push pull set up? I did one of them SketchUps to show what I mean:

They're taller than I'd actually build them but turn these sideways and with 8" subs you'd have a pretty small profile pair of subs no?

Open baffle subs have to face the listener.  There is a null in the acoustic radiation pattern at 90 degrees to the driver front.

[TRADERXFAN]

The side walls change the output curve, the shelving function would change a bit if you did that design. But should still work ok.

The freq response would be a start or whatever you're willing to share.

That makes perfect sense now that you point it out.

Neat!  I just checked out the updates on the website.

I read the page on the 8" woofers.  In the end, did these end up being configured as double-duty drivers for boxed and OB applications (suggested somewhat in the text), or did Brian end up having a different version made for boxed applications?  Also, with the new servo amps on the way, is there still a new model in the pipeline with different faceplate dimensions to compliment the smaller baffles possible with the new woofers?

Any updates on any kit designs implementing the neo-10 and or the 8" woofers?  I understand that keeping the woofers low-key until the next batch of amps come in is probably a good idea, but the neo-10 is kind of an orphan right now without a kit to call home.

The freq response would be a start or whatever you're willing to share.

A frequency response with the servo subs can be anything that you want it to be. Here is a near field measurement of an SW-12-04 in a sealed box.



I made two measurements at each setting for consistency checking. This was with the crossover control set at three different settings.

A near field is about the only way to measure these things outside of an anechoic chamber (a really large anechoic chamber). I could take a room response measurement but what I get in my room will not be anything like what someone else will get in their room. I can even move around the mic and my room and get really varied readings.

The 8's are the same. The servo controls everything and allows the woofers to do anything.

I could take a near field response with an uncontrolled conventional amp, but why? That would be like an auto manufacturer posting gas mileage figures for 10 miles an hour. Who cares! No one is going to drive around at 10 miles an hour. You're a car guy too so you got a car metaphor. 

[Danny Richie]

Trismos,

Think H frame.... And with a side panel depth of at least 12".

Also, if wanting a sub only then go with the 12's. The 8's are designed to be used on smaller baffles on  OB three way designs. And the really light moving mass is for more speed and accuracy.

The new amps being developed for the 8's will allow you to roll the bottom end off so that you can hit higher SPL's without over driving them to exertion limits. Or play really low but in a more limited SPL role.

How about a pair of the SW-12-16FR's built into a bass and frame for a pair of 3.7's? The 3.7's are on the way.    I am also going to try a pair of the 8's in a bass and frame for the new 1.7's.

Even though the Qts is pretty high the woofer size is still pretty small. So no problem using them in a box no smaller than .7 cubic feet.

Brian did have a lower Q version made though. And they might even work well in an air space as small as .3 to .4 cubic feet of air space.

Also, with the new servo amps on the way, is there still a new model in the pipeline with different faceplate dimensions to compliment the smaller baffles possible with the new woofers?

Yes, a narrow profile amp is being developed for these woofers.

Any updates on any kit designs implementing the neo-10 and or the 8" woofers?  I understand that keeping the woofers low-key until the next batch of amps come in is probably a good idea, but the neo-10 is kind of an orphan right now without a kit to call home.

Neo 10 designs are in the works. I am waiting on cabinets.
