If you could have NEW SDA speakers would you want...

If polk built new SDA speakers would you want the SDA in a pure acoustic form as they were in the old ones (separate speakers and SDA cable) or would you want the SDA created in electronics by using an external xover like the SRT's used?

I would want the older form using seperate speakers to create the SDA (not a bose type external sda box) because I consider the older form "pure". I don't think I could live with putting an external box in the tape loop or whatever. This is something I did not like about the SRT system!

The box does not go in the tape loop ... It goes between the amplifier and the speakers much like a crossover.

Although the purist in me would rather have a version without external electronics, what I would want most is that which produced by whatever means the closest likeness to the original surroundings of the recording without regard for the methodology used i.e. the end justifies the means.

Hmm, I thought it did. I stand corrected. I guess maybe I'm thinking of the subwoofer control? Good to know I'm mistaken The question is still valid so far as I wouldn't WANT it in a tape loop driving a single set of speakers rather than passive driving a separate group of SDA speakers.

I think Polk should come out with a 16 midbass, 8 tweeter, 2 15 inch PR per side monster hybrid SDA......whats so special about 8?

They could call it the polk V16!

If you like I can scan and upload the wiring diagrams for the SRT Controls Centers usage.

As far as it's usage for SDA it's really a very simple box with one input for already amplified left and right channels. In addition it also has an input for LFE. Most of the controls of the SRT box are actually for the SubWoof and are not unlike the controls one would find on any standalone Sub.

The box splits the left and right channels into two parts to separately drive the SDA & Stereo arrays. If one prefers one only needs to run one output for each L & R channel from the control box to the SDA arrays as it's the control center for the effect which I suspect when set to NORMAL mode is not unlike what the other SDA's do internally. The difference however is that one CAN set the effect to NORMAL, WIDE or OFF. If you recall the conversation in the other thread regarding the 20 foot wide piano solo, this is where OFF would come in handy. I suspect there are situations where WIDE would also come in handy as well but that's pure speculation. Among other things this alternative way of wiring allows the front speakers to be bi-amped or tri-amped.

I'll take mine the same as the original, thank you very much.

Please do...

My vote for original style, but adjustable SDA presence would be nice.

Also, I would like to have a quality set of speaker wires ordered to your specific length that had the SDA cable attached and would connect towards the back of the amp.

Just less clutter, I guess. Yes I know this defeats using your own custom speaker wiring, but how many used custom wiring for the SDA signal anyway?

I think a 20 Year anniversary model would be great! Limited run to preserve values, maybe preordered.

Original, don't fix it if it ain't broke...

DG's comments brings up an interesting question ...

Without the interconnect cable in place do the SDA arrays of SRS's play at all ?

They do not play at all if the sda cable is not connected. I would vote to have an extra set of binding posts for the SDA rather than a proprietory connector like they have now. That way you could use whatever wire you want. They would need a big warning label back there to keep the uninformed from hooking up wrong!

This is how the SRT's are set up i.e. with different binding posts for the SDA and Stereo arrays ... with the Stereo array being itself biampable ...

There is no interconnect as the electronics are inside the control center and therefore outside the speaker cabs. In addition this would imply that there is no requirement for using a common ground amp.

Tour2ma,

Scan #3 is a little rough. There are a lot of additional pictures and descriptions, but I'm not gonna upload the whole manual. I think what I put up provides sufficient insight to how the system works.

I cleaned up some of the scans and reloaded them.
