  • Now those are the kind of solutions I don't mind having delegated. They're snug now. I was redoing the tweeter leads in 16g OFC and I removed all the set-pins in the X-over terminals and re-crimped then shot with deoxit....
  • Was playing at fairly loud vol. all day and started hearing a rattle. Thought it was my CRS knocking over sockets in the tool chests again. Nary a situation. Discovered the factory inductor nut came loose, so installed longer stainless hardware with…
  • 4 months on backorder, I forgot where I read I need to replace "458" transistors with these ksc1845's
  • Very intriguing anomoly with my 6511's also. Installed alongside the 6510's in my CRS+ they also looked as if they were moving alot more in relation to the 6510's. After removing the passive radiator and installing a Power Port, their movement dimi…
  • Im Tenn's case it gave him a smaller foot print, he had everything already on hand, better bass response to his liking, and arguably better detail of the highs. And lastly, he followed the advice of Mr Polk and experimented.
  • Great analogy Tenn. Some folks like the best of various designs amalgamated into one hybrid that does it all. Toyota V12 mated to Vette transaxle grafted into a GT Porsche comes to mind. That said until you've driven the hybrid, don't knock it. I i…
  • Tennman, are you still running these hybrids? What is the tweeter center distance from the stereo MW on the 10's? I'm finding better sound with the tweeters moved closer to stereo MWs. The SDA MW to stereo MW distance is almost indistinguishab…
  • Thanks for that link. Just read it in it's entirety and find it strange that the CRS+ tweeter crossover is 2.5Khz vs. the 2B at 2Khz.
  • The SDAs leave you pondering your next selection and anticipating the best from the oldest recordings... Gabor Szabo's Dreams sounds like it was recorded in the same room. Before on 2-chan it lacked the same depth. Firing up some classic Jiro Inag…
  • A challenge would be to incorporate the drop-offs into the design. Watching the light show from the back patio and had to chime in. Nice project....Happy 4th everyone.

  • After the polyswitch eviction that was creating a nasty distortion, I installed 1.2 ohm Mills resistors in their place and we are back to a good balance with crystal clear highs. I believe we'll be clocking the left channel tweeter at 2 o'clock and …
  • My XSive soundbar.....
  • I thought I posted a pic in another thread. I recapped and LEDed (sic)my old Akai AA-1050. The sound is intoxicating to the cochlea. I heard the Marantz 2230 with the 5jr (no passive) and they also sounded excellent. It just seemed like the Marantz …
  • GWG, what were the final outside dimensions when you were done? Again, very nice updated look on these.

  • I concur, as with mine, the distortion was in 2-2.5khz range. The synths on "Walk of Life" were about to become the walk of death for the tweeters. Where's F1, this mod is not official until I get his blessing hehe.
  • Pleasantly surprised. I pulled both and the right channel offender measures 1.6 ohm, the left channel measures 0.4 ohm. MCI 500 is imprinted on both... I replaced both with the Mills 1.2 ohm spares I had on hand... Dire Straits don't sound so dire…
  • Just found this thread. I believe this is the reason my RD0194s sounded somewhat veiled on my CRS+ After long cap burn in, I am now clearly hearing some distortion in some synth and horn frequencies. Since I previously installed 2.0 ohm Mills res…
  • Mighty assumptive Heiny, 1" HDF just like the rest of the enclosure. Ill be making slightly longer aluminum brackets when I go to mount in living room. And thru drilling to make them mount easier/quickly. The RD0194 sounds pretty good brightened…
  • Still exercising the caps at moderate volume and the mids are sounding gorgeous.. I ran across a calculator on another forum I want to see if my WAG comes close to the calculator. With the mw6511 I am using a 3.75" length x 2.2" I.D tube flared wi…
  • My test mules are mounted directly to the walls burning in the new caps. Try that with a factory set CRS+ and see how you like the bass response. The curve in the bracket allows clearance for the factory inductor coil leads. I dont think …
  • In response to FTGV, you are correct in your analogy of a standard port. In my application I am using Polk's Power Port which has different design parameters than a standard tube port. It uses shorter and smaller diameter tubes to achieve the same t…
  • Maybe in your book, but in mine it elucidates the fact that it takes more power to run a passive radiator. After the cap install the mids also kicked in. Happy Fathers Day.
  • I've been listening to as many genres of music with the tweeter at 3 o'clock, 1 o'clock, and 11 o'clock (same as factory but closer to stereo driver). 1 and 3 sound identical in wider soundstage, whereas 11 seems to narrow it back down. I'm having …
  • Was afraid of that. Would have been nice to have all be right there accessable by 4 screws.
  • WMG, can the Erse inductor be mounted right next to the board like in your 1st pic? Or will it interfere with the tweeter inductor coil? Ill be making a cover and installing board to back of Power Port platform....
  • If indeed the case, it's indicative of the various driver layouts between different models. Although I'm not installing the SL5000, it does allow closer proximity to the stereo driver, sounds better (to my ears) than the RD-0194. However the SL nee…
  • Exactly what I wasn't sure of, Pitt. WMG says crossover is 2K. of stereo driver and tweeter. I haven't ran across any info of where the SDA driver slopes off in it's higher Hz region or meshes with the opposite side tweeter's lower region.
  • No turbulence or "chuffing" here. If Mr Polk revisits the CRS+, he should use his Power Ports. More bass output per power input than the passive is what I'm discovering. Another reason I did this is because I can and have substituted the mw6511 w…
  • There's either one or the other, not both, with a simple plate that bolts in place of the PR.
