hi danny,

im interested to get the SW-12-16FR for bass application in OB, i have amps available, and using miniDSP for active xo and eq.

is this possible? SW-12-16FR + ucd400 with miniDSP?

cheers

I'm not Danny, but unless your electronics can emulate the control circuit for the servo system, I'm thinking that the Eminence drivers used in the V-2 would be a better fit for your available gear?

[jparkhur]

Ditto.. have to be servo controlled...... 

[Danny Richie]

Yeah, once you go servo control you won't go back. And the servo system eliminates the need for any of that stuff. The controls on the servo amp will even let you EQ the output to control room issues.

Hey, you can cut the multi wire cable between the pre and the amp, solder a rca on + - and a power contact on/off. Then you can use MiniDsp or oder X-oversystem and you still have the servo, and I can tell you i`ts not bad. I do it in my ovn system.

Sorry Danny i`ts true.

[Danny Richie]

Interesting...

[JDUBS]

Do you mind elaborating on this?  How does the servo work in this instance?

Any pics of what you are doing?  Its kind of hard (for me at least) to visualize.

Thanks,
Jim

It is ok to me, to take some foto, but my morale tells me that I have to get Accept from Danny and Brian before.

[Danny Richie]

If it is okay with Brian then it is okay with me. It is his amp and his patented technology.

[Erpeder]

Fine Danny.

First I am very glad for those subs and amps, but my main speakers are line source planer (dipole) going down to about 200Hz. I have make a new and thiner ribbon so I have to make the x-overpoint higher than the sub amps can do. My x-over is a digital IR DSP/PRE. unit. The x-point is now 350Hz. 96db slope. I have placed the subs about 2 feet backward the planar, and with the DSP I can make a perfect phase between sub and planar. Do not boost the subs more than Rhythmik requirement in the low. In my system I have 36db slope at 23hz. to protect the woofers. I don't use room correction, only EQ.

I will take some pictures in the near future. I hope you can read my danish school english.

Thanks.

[Danny Richie]

Your English is great.

In my system I have 36db slope at 23hz. to protect the woofers.

What are you protecting them from? I use the 14Hz extension filter setting and have had them hitting 18Hz notes at a room level of 105db with no issues at all.

[Redefy Audio]

hi all,

thanks for the opinions.

i guess if i chose to use other amps than rhytmik, i will lose servo advantage.

the thing is, i have few amps on my hand and miniDSP, im looking for bass woofer to improve my OB. anyone ever use the SW-12-16FR without servo amps?

cheers

That would be like getting a new big screen TV and watching it without ever turning it on.

Danny you are hard core;-)) I will think about it next time I make new filter and let it go lower.

I have make some measurement with my Crown Cts1200 amp to sw 12-16fr in w-frame. The woofers go higher with out the servo, becource the servo make a cut off. In the low end the woofers go lower with the servo amp becource it is the servos job to do that.
And yes you have to use the servo amp with these woofers. So if you will use other amps then use other woofers, but you don't no what you mis.
I have to new AE18" dipole to, and it is not the same as GR / Rythmik, Ae is okay but no more.

[Erpeder]

Ok here there are some foto after cutting off the preamp in the Rythmik amp. The red wire is for nothing.

Yes, a standard woofer in open baffle, no matter how good, is still no match for our open baffle woofers with servo control. Some how I need to do a better job of getting that word out there.

[LarryB]

I too can vouch for how amazing the OB/servo subs are.

If more manufacturers heard them, I suspect they would incorporate them in their designs, at a variety of price points.

Thanks!  Do you mind commenting on what each of the wires is for / doing?  What is the switch for?

Thanks,
Jim

Hey Jim.

Green     RCA +
yellow    RCA sleeve

The switch is to power on and off the amp.

In my case Brown on
                Orange off
                Black is connected by a resistor to the middle pole. I don't no the         
                value.
I`ts not my job it is a electronic man who have makes it for me. I only make ribbon speakers.
