SDA SRS rebuild ?
Comments
-
I concur. I rep a speaker line that has a $30,000 pair of towers and I STILL like my SRS SRS2's as well as anything. Plus, 20 years ago, I was building custom passive crossover networks for mobile electronics stuff (competition stuff) and building my own home speakers since I liked to tinker. Be it, they weren't anything high end, but I still used quality caps.
Speaker technology in general hasn't changed that bad in the last 30 years...only the materials used in the drivers, computer aided technology, etc, etc. But, it's still all about the sound. I've heard many speakers that sound similar especially a lot of the Canadian speakers (PSB, Paradigm, Energy, etc). It's just all a matter of personal preference.Richard?

avguytx, Do you work for HIVI/Swans. The Swans 2.3HT is a 30 grand HT system. Those things look awesome. -
No. Canton Vento 1 DC and are just a pair of towers with nothing else.Richard? Who's your favorite Little Rascal? Alfalfa? Or is it........................Spanky?.................................Sinner.

Thats cool man, Canton makes some real nice stuff.

I'm planning out a crossover rebuild for my SDA SRS speakers and I have been reading bits about the 2-750uf caps being removed all together and the circuit just wired through without any issues in sound. Are these the caps that protect the tweeters from an amplifier thats being driven into clipping? Or are they there for some sonic purpose?

Welcome to the forum. As a SRS owner, I'm looking forward to hearing your results. -
The "bass thickness" can be cured easily by going to air core inductors and top quality damping material in the SRS's.
If that is true, I must then wonder why Polk's engineering department went to such effort and expense to re-engineer and redesign the cabinet structures of the 4th and 5th generation SDA SRS's as "monocoque" cabinets.Darqueknight, I'm intrigued by the fact you somewhat agree with my thoughts on this subject seeing you think the SDA is an outdated technology.
Yeah, I don't like anything old except money.;)Yeah, that's why he owns 5 or 6 pair and I own 3 pair. Outdated my hairy white ****! :rolleyes:
Five pairs...down from nine. Will be up to 6 pair soon as I find a conveniently located pair of 3.1TL's in good to mint condition.:) I used to hoard SDA's, but I'm cured now...now I just "collect" them.:)20 years ago know one talked about doing x-over upgrades like today. You were lucky to get a pair of speakers that had gold plated binding posts.
Premium parts, in mass production quantities, were hard to come by 20 years ago. Even when premium parts were available in sufficient quantities, the cost of the parts was usually prohibitive for a manufacturer building to a particular price point.Even the last generation 1.2TL's could use added damping and quality internal wiring.
Prior to doing my first SDA modification in 1990 (a pair of SDA 1B's) , I consulted with Polk's engineering department to get their recommendations and caveats. I would certainly recommend seeking advisement before I modified the cabinets of a 1.2TL. I look forward to reading your report on replacing internal wiring. I was advised by a Polk engineer that replacing the binding posts and replacing the internal wiring would have no audible effect. My experiece with replacing the internal wiring of my SDA 1B's and the binding posts of all of my SDA's confirmed that. However, that is not to say that you won't realize some audible benefit with your ears, equipment, and other SDA's.Proud and loyal citizen of the Digital Domain and Solid State Country! -

This one is going to be a small step process and the last step in order to achieve the correct bass responce. I want to see how the crossover/wire upgrades improve the bass performance first. I think the bass may tighten up with these upgrades. The "bass thickness" is really not an unpleasant sound and only seems to show through on older recorded music like 70's rock. A little tightning up is all I was suggesting. Obviously Polk must have felt the SRS's were a little on the thick side if they went through the trouble to tighten up the cabinet. I'm not going to start rebuilding a speaker cabinet that for sure. Now were just getting crazier than what you guy's think I am already.

i have very little to say here but, i will say one thing!! i sold my speakers to ed and he was very happy them and a very nice gentlemen. i wish him all the luck with what ever up-grade he decides to do. also, by selling my polks to him i was able to buy the infinity rs1b's ive always wanted. they are 20 years old also but sound nice and im not doing any up-grades on them what so ever. you guys all fight over how out dated the sda-srs's are while i enjoy my infinitys, lol
-
i just had to throw that in,couldent resist
-
buy the way sal, are you ready to come over to pa to hear what you are missing????????????
-
I would hope for the extra money that the RS1B's cost they would be better but for what some of us have in the ones we have, they can't be beat. Have fun with your Infinity speakers. I guess if I had the money to blow, I might have a pair. But, I'm perfectly content with the 2 pair of SDA's I have and don't feel I'm missing anything thus far.Richard?

I knew there was a little SDA still left inside of you. Thanks again for seamless transaction. The infinity's are one of the best ever made on a small list of the best . I only wish they had Polk's customer service.

:cool: Lasereath, Have you used the blackhole 5 in your SDA. I dont think there is enough space inside to accomidate those 5 layer bricks. Parts express has another damping material like Blackhole 5 that has several different thicknesses to accomidate just about any speaker application. It's also self adhesive. Have not tried it yet.
-
BTW: Parts exspress is a little pricey on their shipping, kinda of a ripoff to put it nicely
-
Has Anybody Tried Black Hole #5?
My subwoofers use them.....
It is very nice damping material. Much better than regular foam...
The cool part about the design is that extremely hard layer of foam that basically contains the vibrations. I would say its a huge upgrade for damping.- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
sal, no tt. but as soon as the brat goes back to school in september i will let you know. you and joe are welcome. i better start up-grading the crossovers on the infins so they sound good,lol
-
AVGUYTX, the polk speakers i had were great. they sounded good!!. but to me, the infinitys sound better. more laid back if you want to put it that way. there was a pair of 1b's on e-bay last week in florida in mint cond. that went for $2,600. now how can you beat that!!
-
for those that want to know, the speakers under discussion here have the new silk dome tweeters. so they do sound better already.
