running without SDA interconnect

This may be a dumb question (most likely is) but running these speakers without the SDA interconnect is fine...right? (meaning...it doesn't harm the any of the speakers or crossover) They just act like normal speakers without this line connected? I will chime in more with why I am asking this....did some blind tests tonight...more on this later.

You will not cause problems with the crossovers or drivers. You simply won't be using half of your available drivers. You essentially get half the speakers when running without the cable.Ludicrous gibs!

The really cool thing is even without the sda effect running, they still sound better than most other speakers. :cool:"SOME PEOPLE CALL ME MAURICE,

True, but they still sound pretty good without the cord, just not NEARLY as good as with the cord.

I keep hearing people saying that the SDAs only use one driver (or half the number of drivers) instead of two in a pair of SDAs that have 2 midrange/bass drivers with the SDA cable OFF. This is NOT true! Take my SDA 2A's for example, WITH the SDA cable on the inner drivers do the BASS and the outer SDA drivers do the midrange only. WITH THE SDA CABLE REMOVED they do in fact act like a pair of Monitor 10's where BOTH 6.5 inch drivers do midrange AND bass with the SDA cable REMOVED. Thinking that only one driver is active without the SDA cable is just silly! Read the old manuals on how the SDA technology works. You will also noticed less bass with the cable on because only one driver is doing bass while the other SDA driver does the midrange only. PolkFreak

No...
The drivers that would normally be turned off with a midrange signal are now just moving free-air with the air from the midbass drivers.
They are acting like a bunch of PRs...
If they use 4 drivers total, 4 drivers should be working properly..
If they use 8 drivers total, 8 drivers should be working properly...
They were designed for all drivers to work.
The Stereo drivers do the entire spectrum a midbass needs to do. The SDA drivers send out that crosstalk cancelation signal... atleast from what I understand... (which is a L&R Signal mixed) It has nothing to do with bass response.- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -

PF,
Yea, were just a bunch of silly old ducks that dont know what were talking about, thanks for setting us straight. I going to use my connect to tie the boat cover on.

The reason you may hear less bass with the SDA cable connected is because sometimes a given set of frequencies being reproduced from the SDA array (out of phase) matches the same frequencies of the bass from the main drivers.Vinyl, the final frontier...

Not sure if you are the original owner of these or not, but I have "heard" of some people getting SDA speakers that have been re-wired to act like conventional speakers. One to note was someone that wired all the drivers (dimensional and stereo) in a series/parallel configuration to see what they would sound like (wait a minute) that person was me... I did this on my SDA-1's to lower the impedance to get more power from my amp. I was reading less than 2 ohms from the terminal. It didn't take me long to wire them back to their stock form...
Open your speakers and see if they are all wired together....

Regardless, why would you WANT to not use the SDA cable?
Personally, I generally try to use things in the manner that they were designed. So, while PF may very well be a friend of the hookah, does it really matter?

I think what he is trying to get at is that he has a new set of Bryston monoblocks that won't work with the original SRS's, so how do they sound when are not hooked up with the SDA cable.
This is what I gathered this from the other threads autoconsortium has participated in.Tschüss

Nah, not really. I was just checking to see if I could get more out of something less, (less, being what the engineers intended), I can't say I got more, but then again I didn't really sit and listen to them for a long extended period of time...

In this case, then why not? If you have monster mono's and you want to hook them up then it may be a good idea to re-wire the drivers to use the mono's and ommit the interconnect. With some different' wiring schemes you should be able to get the same impedance as the original configuration, (or at least close). You will not have the "dimensional" experience, but you would have a good conventional speaker....
There is only one way to find out, try it...
scott -
Well, one reason is that neither I nor this Club has ever supported the creation of FrankenPolks. Sure he owns them and can do whatever he wants.
Understand wanting to use those mono's but the solution is to get a set of SDA that can be run mono, their readily available, then you get all the benefits of the speaker without sacraficing the intent of the speaker pair -

virtually....yeah dude
Sda's were built with one purpose, to act like SDA's with the cable hooked up
most people on this board hold the SDA's in high regard, and speaking of rewiring and changing them around to make conventional speakers is just silly talk, no disrespect intended.
its kind of like taking a great steak, then cutting it into thin slices, burning them on the grill, putting them on wonder bread and saying "hey, look at my kick **** sandwich!" Dude, you just had steak for gods sake!!!

Last I looked, it was an unanswered question that was brought up in a couple of other threads. The serial number range for AI-1 use with SRS's was mentioned by BobMcG in this thread but I never saw a response to whether he is above or below it.Salk SoundScape 8's * Audio Research Reference 3 * Bottlehead Eros Phono * Park's Audio Budgie SUT * Krell KSA-250 * Harmonic Technology Pro 9+ * Signature Series Sonore Music Server w/Deux PS * Roon * Gustard R26 DAC / Singxer SU-6 DDC * Heavy Plinth Lenco L75 Idler Drive * AA MG-1 Linear Air Bearing Arm * AT33PTG/II & Denon 103R * Richard Gray 600S * NHT B-12d subs * GIK Acoustic Treatments * Sennheiser HD650 * -
Fire from the Sky, shells coming in :rolleyes:
I was giving this guy that is having an "issue" with his set up an opinion on yet another option that he has, if he wants to run the Brystons with the SRS's he has. It is just an option, that is all. It certainly isn't criminal to change what the engineers intended. A lot of SDA owners have changed out, replaced, or otherwise modified their SDA's. Crossovers, tweeters, even the interconnect. So I dont' really see why it is a big deal for his case in modifying his speakers to fulfill "his need". From what I understand, he doesn't have a set that will work with the A1 interconnect. They are his speakers, he can always try it out, and see if it works for him. It doesn't take that long to re-wire them...
Help a guy out, just don't say it will not work and not give other options, (besides, buy new speakers or buy new amps), we all don't have the capital to go out there and buy, and buy again.
