How to improve your Polks (or... how to build Tannolks)
- Thread starter Redboy

You're a craftsman, Gary. I'd have probably put the port in the plywood, mounted it to the back of the baffle, and then used a flush trim bit on the router to match the baffle hole to the port ID.
Nate, glad to be of assistance. I just want to know how they sound!!

Excellent Idea. I may not be able to build a decent looking complete speaker but putting a new baffle on an existing one is something I could probably handle!
Excellent work, I bet they sound wonderful. Are those Tanoy's coaxial? Wouldn't know it by looking at the fronts.

well done! inspiring as well . i have a pair of infinity sm120s that i'm just dying to
gut and turn into musical speakers . the minor difference is that the infinitys are
still intact!
the sound of these can only be described as "annoying" or "hollow", so i'm
certain no-one would complain if i hack 'em. possibly the worst pair of speakers
i've ever owned ($12 @ flea market) :yuck:

i'm speechless..... why not just build your own speakers?

They've been known to do that too. :yes:
Good work guys. I bet they'll sound great.
That port install is quite a trick, leaves the port opening with the wooden, more appealing look and functional for changing lengths. But what else would one expect from the Stradavari of St. Paul

I found them on Audiogon. Here's the story of how they got to MN - made possible by good people at AK, especially ta131js who went way out of his way to get these for me.
I'm indebted to a bunch of AK people for this project. This is a cool gang of audionuts we've got here! Some of the players in this episode:
ta131js - picked up the speakers in CA and shipped the drivers to me in MN
doucanoe - bought the (empty! - no Polk drivers were harmed in the making of this speaker!) Polk cabinets and donated them to the cause
ejfud - did all the work on them
RayW - gave expert advice on cabinet tuning
Several others spent time running numbers in modeling programs and digging around for specs. This wouldn't have happened without all of these guys. Thanks is not enough!doucanoe - bought the (empty! - no Polk drivers were harmed in the making of this speaker!) Polk cabinets and donated them to the cause

Recycle!
I hate to see nice cabinets go to the landfill. Plus it saved Redboy some money on buying "good" plywood to make cabs from scratch.

We had been discussing cabinet design for Nates drivers when I happened across the Polk cabs. The previous owner got tired of waiting for the drivers to come along at a reasonable price and gave up on the project.
On first sight, it looked to me that they had "Tannolk" written all over them. I figured that they would at least make for suitable test box to experiment with tuning. The extra bonus was that if everything played out right, they would be cosmeticaly what Nate was looking for in the first place.
ejfud had all the real work and it looks like with Gary's dandy handiwork, everything has come together nicely!
Another fun MN collaborative effort.
Now, its time to listen :thmbsp:

Very good re-use of basiclly a good platform. I too am a large fan of recycling boxes and coming out with quite acceptable results. You mentioned reuse of your SM120 (Infinity?) boxes. Here is what I did with mine. I restuffed them with EV 12W woofers, EV T350 Horn tweeters, and a great sounding Piezo mid horns! I also beefed up the inside with more internal bracing, etc. These turned out very nice and sound better than I had hoped for!
So what I am saying/ promoting is to take these essentially good platforms and built something you really would like. Reconstruction of baffles are a great way to start.
