SDA SRS 1.2TLs - The restoration begins

With the help of @nooshinjohn posting a nondescript e-bay listing on this forum for a pair of Polk Audio Crossover Speakers, I was able to acquire my first pair of SDA SRS 1.2TLs.
https://www.ebay.com/itm/Polk-Audio-Crossover-Speakers/322818292288?ssPageName=STRK:MEBIDX:IT&_trksid=p2055119.m1438.l2649
I have always wanted to get a pair of 1.2TLs, to hear what improvements had been made between the SDA SRSs that I already own and the 5th and last generation of Matthew Polk's tour de force, the 1.2TL. And here was an opportunity to acquire a pair relatively close to home. And in Walnut to boot (my preferred wood).
It was a nice sunny southern California Sunday (70F) and it was a great day for a drive. So I loaded up the Prius with moving pads, a collapsible hand truck, some tie downs (just in case) and headed out to the desert.
The seller was located out in Canyon Lake, near Temecula CA (very dry and arid), about an hours drive from my house.
As I pulled up the seller greets me with a wave, and we go inside to check out the speakers.
They were tucked away in the back bedroom, not having been used in some 20 years (and they apparently had been loaned to various people over the years, which is never a good thing to hear!). From across the room, they appeared to be decent shape. The seller said they were in "perfect" condition when we had talked on the phone earlier in the week.
As I got up close however, I noticed what appeared to be some swelling at the bottom of the grille on the left speaker.
I suspected that water had possibly been spilled on the speaker, or worse yet a dog had mistaken it for a fire hydrant and relieved himself on the speaker! I got my nose up against it and no urine or any musty odor of any kind.
I rocked the left speaker back and put my hand under to the feel the bottom plank and it felt smooth and solid. No major concerns, as if the grille was swollen from water, I could always sand it down to the correct thickness when I replaced the grill cloth.
I then inspected the right speaker. There wasn't any swelling of the grille, so I didn't rock it back to check the bottom plank (mistake! - lesson learned, trust your gut and run your hands over all 6 sides of the speakers!).
The seller had said that he had the IC when I talked with him on the phone. However when I got there he could not find the IC, and was willing to lower his asking price $100 for the lack of the cable. I mentioned the potential water damage, and he dropped another $100. We shook hands and we were both happy.
As we hauled the SDA SRS 1.2TLs out of the back bedroom on my hand truck, I noticed that there was water damage on the bottom plank of the right speaker. I suspect that the grilles had gotten switched between the 2 speakers at some point in time and that's why the left hand grill was swollen at the bottom.
Into the Prius they went, and I got a better look at the bottom plank on the right speaker. The wood veneer was severely delaminated, but above that, the speaker MDF structure didn't appear to be affected.
So I knew some restoration work was in my future, but hopefully just cosmetic. The seller said if I had any issues with them, he would give me my money back and would even come pick them up. I respected that.
When I arrived home about an hour later my son helped me unload the SDA SRS 1.2TLs, and I spent the next couple of hours giving them a good scrub down.
Every pair of the large SDAs that I have purchased (3 pair now) has had white house paint splatter on the back! Always a PITA to remove without damaging the vinyl. I guess these speakers are too big for most people to move out of the room when they paint!
After cleaning, and removing all the white paint splatter, I put some vinyl/rubber protectant on the fronts and backs, and they look brand new again.
Today I decided to remove the bottom plank from the right speaker to see the extent of the water damage.
PR removed to inspect for evidence of water ingress, none observed.
4 retaining nuts and washers removed and bottom plank liberated from the box structure with ease.
It does not appear that the cabinet structure was compromised due to the water exposure. There is a very slight swelling of the from baffle at its lower edge. I do not think I am going to address this as its a very subtle.
Since I had the PR out, I gave the rest of the interior a quick inspection. I was surprised to see that Polk used a piece of the walnut trim as a front baffle brace! Does anyone else noticed this?
All I can think of is how did this water damage occur? They must have been sitting on a soaking wet carpet for a very long time.
So far nothing I cant address. I'm going to removed the bottom plank from the left speaker now to see if it has any hidden water damage as well.

"I am going to need to replace the bottom plank on one of them as it has severe water damage (veneer peeling off). I am going to remove the bottom plank to see if the water got into any of the MDF box structure, but I don't think it did."
You got lucky my man! Didn't soak into the box at all by the looks of it.
Just get some real walnut. Check out this seller on Ebay for some nice stuff;

Looks like they took an offcut of veneered chipboard for the brace, probably the same sheet they used for the top and bottom plates.SDA SRS 2.3s

Welcome to the 1.2tl club
when i picked mine up one of them had a similar problem with the moisture problem on the bottom plate. I was able to scrape and sand all of the old veneer off and the mdf underneath was in very good shape. I then sanded and re veneered both speakers...hopefully you will have the same luck.
I don't think you want to use solid wood for the top or bottom plates as hardwood has a tendency to crack with temp change. I believe the original SRS had this issue. -
@Rrusse11 I know! I just put the right speaker back together (future project), and removed the bottom plank from the left speaker.
The bottom plank from the left speaker is in great condition, no signs of water damage anywhere. However the lower edge of the from baffle appears to have started to swell along the lower edge, more than the right speaker (with far worse bottom plank water damage - go figure).
I have heard that veneered top and bottom planks are more stable than the solid hardwoods. So I will probably go Walnut veneer, and redo all the top and bottom planks, and refinish the side moldings.HTAdcom GFP-565 Pre-amp, Adcom GFA-565 Mono Block Amps (Front), Adcom GFA-585 Amp (Side), Adcom GFA-555 Amp (Rear), Adcom ACE-515, Pioneer CLD-3070 Laserdisc, Sony CDP-605esD, Sony BluRay BDP BX59, Samsung 50" Plasma, Polk Audio SDA SRS 1.2TL Front (Walnut), Polk Audio SDA SRS Side (Walnut), Polk Audio SDA SRS Rear (Walnut).2 Channel (Living Room)Adcom GFP-565 Pre-amp (w/Big Sky Audio Upgrades), Adcom GFA-565 Mono Block Amps (w/Big Sky Audio Upgrades), Adcom ACE-515, Sony CDP-705esD, Magnum Dynalab FT-101A Etude, Polk Audio SDA SRS 2.3TL (Walnut), Polk Audio SDA SRS 2 (Walnut), STAX SR34 Electret Earspeaker System.2 Channel (Office)Adcom GFP-555 Pre-amp, Adcom GFA-555 Amp, Sony CDP-605esD, Adcom GFT-555 Tuner, Polk Audio SDA 1C (Walnut).2 Channel (Garage)Hafler DH-110 Pre-amp, Hafler DH-220 Amp, Sony CDP-505esD, Hafler DH-330 Tuner, Polk Audio SDA 2B (Walnut). -
@Gerres26 I agree with the Walnut veneer vs solid Walnut. Both pairs of my SDA SRSs have the solid Walnut top and bottom planks and have both experienced some minor warpage.
The veneer on the bottom plate can be peeled off by hand. Also it appears that there is a solid wood front and rear edge piece glued to a substrate (MDF?). Was that how yours was constructed as well?
As a follow up, my left speaker does not have the Walnut veneered front baffle brace.

Mine were actually oak as opposed to your walnut, but i think i do remember there being a solid edge around the mdf.
-
250GTlusso,
Yes, solid timber will move a bit with humidity. Veneer is fine, but then you have to deal with the edge. Use a bit of plywood as the core, and then glue solid wood for a neat edge finish. Make the trim thick enough and you can mold the edge and put a good radius on the corners.
For me, quicker and easier to laminate a solid board, fastener slots to allow expansion
and contraction across the grain. It's only 13" wide, walnut doesn't move much, one of it's endearing properties for cabinetmakers. I've got some I've been air drying for years. The glues used in "modern" veneering aren't much chop in my book, and they're paper thin. My perspective comes from doing a lot of work on antique furniture, and old boats.
Chip board, particle board, mdf, et al, won't hold up in the long term, IMO. Lol, I want to make stuff that'll live longer than me!
Have fun!SDA SRS 2.3s

Thanks @Jaybeez . Even though I have acquired 6 pairs of SDA's to date, this is the first pair that is going to require serious cosmetic work to make it right (all my other pairs are in good to great shape).
So I am looking forward to learning how to do everything from the CP community!

Looking for help with removing the bottom plate. I just picked up a pair of SDA SRS, removed the passive radiator and removed the nuts for the plate. Can't get it loose from the cabinet, even when tapping aggresively with a small 2X4 and a hammer. Really thought they'd just fall off. Is it possible Polk glued the bottom plate onto the cabinet? Btw, the plate is solid oak (and cracked), is not laminated.
-
Yep originally they were solid wood, to my knowledge none were glued.
-
@sleahy, they should just fall off. If they aren't coming off with small 2x4 and a hammer, then you will need to adopt an alternate removal procedure (removal procedure for the SDA 1C - @F1Nut has posted it before, so do a search).HTAdcom GFP-565 Pre-amp, Adcom GFA-565 Mono Block Amps (Front), Adcom GFA-585 Amp (Side), Adcom GFA-555 Amp (Rear), Adcom ACE-515, Pioneer CLD-3070 Laserdisc, Sony CDP-605esD, Sony BluRay BDP BX59, Samsung 50" Plasma, Polk Audio SDA SRS 1.2TL Front (Walnut), Polk Audio SDA SRS Side (Walnut), Polk Audio SDA SRS Rear (Walnut).2 Channel (Living Room)Adcom GFP-565 Pre-amp (w/Big Sky Audio Upgrades), Adcom GFA-565 Mono Block Amps (w/Big Sky Audio Upgrades), Adcom ACE-515, Sony CDP-705esD, Magnum Dynalab FT-101A Etude, Polk Audio SDA SRS 2.3TL (Walnut), Polk Audio SDA SRS 2 (Walnut), STAX SR34 Electret Earspeaker System.2 Channel (Office)Adcom GFP-555 Pre-amp, Adcom GFA-555 Amp, Sony CDP-605esD, Adcom GFT-555 Tuner, Polk Audio SDA 1C (Walnut).2 Channel (Garage)Hafler DH-110 Pre-amp, Hafler DH-220 Amp, Sony CDP-505esD, Hafler DH-330 Tuner, Polk Audio SDA 2B (Walnut).

Same here, I've done two sets of 1.2TL rebuilds now and the top/bottom plates were only attached via the four nuts on each. They just dropped off in each case once the nuts were removed.
On a second note, all were either loose or in one case, the lag bolt had dropped out of the top plate and was in the bottom of the cabinet making for a massive air leak. Even if someone is not doing a refurb, the nuts should be checked from time to time to ensure a nice airtight cabinet.Media Room: Parasound JC-5, Cambridge 851N, Schiit Freya, SDA SRS 1.2tl

Install lock washers to prevent the nuts from coming loose again. I also suggest installing a foam rubber gasket under the original washer with an ID that is snug to the bolt.Political Correctness'.........defined

On the same basic page here.
I used a ~2" square of the Armacell tape between the top/bottom of the cabinet and the end plates. Armacell square (8 per speaker) over each hole, small slit for the lag screw to pass through and then a washer/split washer/nut tightened over a few days to compress the armacell and form a good seal. The resulting gap between the end plates and front/side panels is not noticeable. Traveling but can post pics in a few days.Media Room: Parasound JC-5, Cambridge 851N, Schiit Freya, SDA SRS 1.2tl
