Just curious -- has anyone on this forum ever attempted to modify their Polk floorstanding speakers? If so, what was done and what were the results?
HT/2-channel Rig: Sony 50” LCD TV; Toshiba HD-A2 DVD player; Emotiva LMC-1 pre/pro; Rogue Audio M-120 monoblocks (modded); Placette RVC; Emotiva LPA-1 amp; Bada HD-22 tube CDP (modded); VMPS Tower II SE (fronts); DIY Clearwave Dynamic 4CC (center); Wharfedale Opus Tri-Surrounds (rear); and VMPS 215 sub

    read my post from 4 15 its on the third page titled sda crs driver upgrade the morel nm 164 mid bass drivers are much improved over the 6 and a half inch polk drivers in my sda these are a perfect driver upgrade for any of the sda or moniter series polks .I talked to a tech at parts express who recomended them and also morel usa they play cleanly and much louder without the bottoming i had with the original drivers .they have double magnets and 3 inch voice coils and rubber sourounds.
    system includes polk sda

    Would your experience with those drivers be applicable to the Rti series?

    Not me personally, but several members have worked on their Polks.

    raife has done as much modding as anyone 'round here. Particularly upgrading crossover components. Nice thread here on this, but buried in another topic...

    I know F1 has upgraded to cardas 4-way posts. He's documented this at least twice in threads.

    RussMan swapped out his SL2000 tweeters for the replacement SL2000T's

    Is will be very hard to mod any driver component on the RT series unless you really know what you are doing....

    First, the tweeter *mounts* into the baffle, and when I say mount - I mean pops in like a 20 dollar toy at walmart. Then the depth of the tweeter hole limits the magnet size, depending on which model you have ---

    The midbass section has to have a flat ring (I guess thats what you would call it) so it can fit with the baffle -- since the RT series uses no screws in their drivers, it is all a matter of fit and letting the baffle and other materials to hold them in.

    The crossover, atleast the RT35i would be easy to mod, but they glued the components to the board, so good luck there as well. The only really easy upgrade is wire, but then you have to be careful about your size of wire, because they cut a hole in the tweeter hole for the wire to pass through and it is only so big.

    By the way, this is based on the RT35i, other madels may vary.

    Hope this helps :D

    I was going to try changing the caps on my monitor 5's to a Solen type cap ?
    Has anyone tried this and will it give me a audible inptovement ?
    The silver coil tweeter sounds really nice in those I just wonder if there is room for improvement ?
    I dont drive these hard in fact they operate from 100 hz and up the subs take the low end .

    Use Sonic Caps or Claritycaps, I'd avoid Solen.

    Anyone ever hear from Brad? I pm'd him about a year ago--but have not heard back from him.

    BTW--sonicaps--they may have a sale now too.
    JC approves....he told me so. (F-1 nut)

    Wow! A six year old thread brought up from the dead. I think that's a record.
