Nice cabs and Peerless tweets and maybe good crossovers for half a hundy? Sounds like a no-brainer.

Frankenpolk is alive and well in Los Angeles. https://losangeles.craigslist.org/lac/ele/d/los-angeles-polk-audio-7b-with-peerless/7272991599.html

I love them. They would fit right in here. I weep for them. Lol. No kidding though, if I were there I would buy them and fix em right on back up. Put some "Mystery" drivers in there. -
I offered him 30 but he didn't bite...

Anybody in the intermountain west following this thread? I just finished up a pair of 3.1TL's, listed locally here in Utah. Could make some arrangements if a fellow polkaholic is in the market and within reasonable distance to meet up. I’m hoping to get $575 for them which is pretty much what I have into them. Holla if'n you’re interested.
Stuff I’ve done to them:
- They’ve been aesthetically refreshed, re-stained with India ink and topped with polyacrylic. There are some blemishes from mistreatment in the past, luckily the worst of it is on the backs. Grilles and cabinet cloth is in good condition, no snags or rips, a little schmegma on them that I haven’t tried to clean off yet, but it shows worse in the photo than it is in person.
- The magnets have all been secured with powergrab to prevent shifting.
- Noico damping material has been applied to all baskets to reduce ringing.
- The tweeters were upgraded with RD0-198’s.
- Terminal cups have all new binding posts and built new jumpers.
- Drivers and passives are all in great condition and the cabinets are sealed well.
- Included is a custom 12’ interconnect cable for the SDA circuit.
Also have listed a CS350-LS in vgc. Perfect working order. $125 obo.
Some photos in no specific order:














Current Collection: Monitor 4a (Peerless), Modified Monitor 7b (Peerless), RTA15TL (SL3000), Full mod SDA CRS 4.1TL (198’s), SDA SRS 2.3TL (198’s), R100's, R200’s, R300 🤩 -

Makes me want to upgrade my spare 7B crossovers as above to make them 7tl's w/ RDO-198's just to see what sort of difference there is compared to Peerless. $650 though? I WISH you could get your labor back in resale value......but heck I'm never selling mine!George / NJ

If you are never selling them, why would you worry about getting you labor $ back. Listening pleasure is also worth something.

I see these vintage Polks go for half the price in CA that I see them sell for in NJ. Probably depends greatly upon the area though. I am not far from NYC and everything is jacked up here.George / NJ

I've bought 4 pairs of 7's over the last 5 years. All of them have been for 30 dollars or less. One pair had peerless tweeters while another had the sl2500.
Vintage Polks do seem to run considerably cheaper out here in California in comparison to other states for some reason. -

At those prices, they are experiments waiting to happen lol. The 7's can afford some interior bracing mods.Don't take experimental gene therapies from known eugenicists. -

Looks like there is not a hole in that Peerless dome. Maybe Polk didn't do that early on.George / NJ

Single Polk Monitor 5a in a pretty decent condition - $25 (Walnut Creek)
I was thinking to get it, but there is nothing in my mind to convince in driving for about 40mls.

That’s a Peerless 5. Good deal for $25, some guys like them for center channel if they have Peerless monitor fronts.

It’s raining monitor 7’s here in Utah. I already have two spare pairs, so yeah... somebody else can chase them... 😂

I do not recall ever seeing a set with the Polk logo down low like that with the wood on the bottom. That looks cool.

I'd love to hear a pair. One of my only Polks to escape my hearing.
Pretty much the same here.
Most people just listen to music and watch movies. I EXPERIENCE them.
