New guy with the 1C modding bug!

Having just purchased a new to me set of Polk SDA 1C's and unable to leave anything alone I noticed some extensive modding being done. Although the Polks sound amazing my OCD says...but what if? I contacted westmassguy and he introduced me to this forum and suggested I join. I have already ordered some new silk tweeters to tame the high end and look forward to the journey. Just wanted to introduce myself, and if everyone is half as helpful as westmassguy I will be around for some time to come.

@sfosselman,
Welcome to Club Polk!
I compliment you on your purchase of 1Cs. I bought a pair in 1989, still have them, still love their sound, and have modified them about as much as can be imagined.
You've chosen a good advisor in @westmassguy.
Actually, I forgot: If there are no pictures it didn't happen! How about some pix of your 1Cs?
Cheers!

You can get the boards from David, he has them in stock and would be willing to build them up for you.“The two most important days in your life are the day you are born and the day you find out why.” ~ Mark Twain -
I just replaced one the tweeters on my 2Bs a couple of days ago with the RDO-194 tweeter. The other speaker already had the upgraded tweeter in it. After rewiring the existing RDO-194 correctly (original owner plugged it out of phase), now both speakers sound very well balanced and the mids and highs are very smooth. I may rethink about replacing the existing components on the crossovers to take it to the next level as you say.RandyCroissant wrote: »My 2Bs went from ho-hum to awesome with the crossover mods, you wont be disappointed.

I'll just add my affirmation to what has already been said about David/westmassguy. You're in good hands with him. I've worked with David on a few of my speaker projects.. and he always has your best interest at heart. The fact that he hearkens from NE Patriots territory, and I'm over here in Latte Land/Seattle... says a lot about his technical acumen and business integrity that I'm able to over look this regional(OK, NFL!) issue. lol.

@sfosselman,
Thanks for posting some great pictures.
Please keep us abreast of your upgrade path. It's always interesting to those of us who have already been down it -- that is, the infamous rabbit hole.
You'll find it well worth the effort and $s.
Looks like a nice rig there.

Right now I have the Polks running off an Emotiva XPA-2 (plenty of juice to get the Polks singing) with a Rotel RSX-1055 as a preamp...my center is a B&W HTM4 that is the only piece left from my B&W system...yes that's right...the Polks reign supreme! There are a few subs in rotarion but right now i dont feel the need to hook em up. I'm running the center off a B&K ST2140...I'm contemplating selling the center for a better timbre match with the Polk fronts. Who knows.... Its all part of the fun....
