Polk 10B Monitors. Crossovers and Tweeter upgrades
wallycroc
Posts: 4
Just found a pair of very nice 10B's that a bought for a great price on Craig's list. I hooked them up to a vintage 60W/ch Kenwood amp. They seem underpowered. I will try my Onkyo 100W/ch receiver. I am guessing these were from the mid 80's and wondering if I should leave them as is or replace/upgrade the crossovers and tweeters? Any suggestions.

60 wpc should be plenty to drive those speakers. Can you describe what you don't like about the sound?

After you describe what you don't like about the sound, or why they seem underpowered, tell us how much $ you have to spend on them.. You can end up dropping a ton of money on Monitors with expensive caps and resistors, RD 0194 tweeters, dynamat, Larry's Rings, etc...
I decided to spend money on my CRS+'s first... Well worth it to me since they get most of the air time. I did put the RD0194 tweeters in my 10Bs, and that made enough of a difference to keep me happy until I get around to the other mods. I think that's the first step for improving 10s, but some may disagree.Lexicon RT-10, Parasound P5, McCormack DNA 0.5, Polk SDA CRS+, SVS Sub

First make sure you know which model you have & what tweeter you have as stated above.
1) make sure your mid woofers are good. Lightly press (in/out evenly) to make sure there is no scratchiness from voice coil
2)push in on the passive radiator & the mid woofers will come out & should slowly go back to normal position 3-5seconds. Thats good. If they dont come out-there is a leak somewhere

.Best way to make sure you have the correct woofers is to remove them 1 at time & look at tags on back. Look up info here http://forum.polkaudio.com/discussion/38755/polk-audio-speaker-wiring-schematics-more-all-models-except-sda#latest .......While your at it Loctite the magnets 3.00 1tube will do at WallyMart. I do the inside one first & spread it out with finger & take excess & apply it to the outside one. Then i wipe it down with paper towel. Make sure you have a few close to you. Easy job. This is to prevent magnet from shifting..

Picture order is not correct here & make sure all area's are filled with glue before drying process.

Any idea what the cost is on RD0194 tweeters. I have a request into Polk for a quote and hopefully they will respond soon. As far as the crossovers I am confident I can handle cap/resistor replacements from what I have seen on the web.
I may dig out my old Denon 200W/amp that used to power my Polk LS90s. -

Another question regarding the 10B's. Mine have dual fuses while I see others with only one fuse. What is the difference? Did Polk change something?
-
Polk was always making changes on the fly. What you describe could be a fused mid woofer as well as tweeter. Then again maybe they made another change and yours could be a spare fuse holder. Only one of two ways to find out.
-
You should post some pictures of the speakers. Drivers and binding post cup with the twin fuses. Just because.Lexicon RT-10, Parasound P5, McCormack DNA 0.5, Polk SDA CRS+, SVS Sub
