  1. I am so glad you posted this Dean. I have read how the AA crossover is preferred by many, but EVERY time I have tried them I thought the highs were more than lacking. ...I thought it was just me and have suffered in silence, until now, lol
  2. ...I don’t have insurance, I consider it gambling and I almost lost the house last time I gambled
  3. Given the option, I would choose unengraved black at a premium for any speaker that has the grilles off. And for me, that is pretty much any speaker in rotation. The silver looks wicked on my LSI Splits though! I owe the two members who nudged Dave in the right direction here a beer. Can you mail a can of beer?

    Miracle whip

    I remember as a kid, my dad asked me to "make us" a tuna fish sandwich. I put Miracle Whip in it. He hasn't spoken to me since.
  5. This is some great input gentlemen, as usual. This is right where I find myself at this stage in the game too. The Bluesound Node is looking good. Thanks for all the suggestions.

    ...talk about cryptic
  7. I lucked into a used NAD C-165 preamp and Emotiva XPA-2 Gen3 last year for pretty much a “2 for 1” deal. Having last owned a NAD C-162 feeding a couple of C-372’s amp sections, I was floored by the significant increase in sound quality. I will say without a doubt though, as @absolve2525 mentioned, if it wasn’t for the Emotiva amp’s powerful bass performance I would miss the more versatile tone/EQ controls of the older preamps. The newer preamps only give like +/- 5 db boost to the bass and treble now. And no loudness control, pfffft... I think the closest I ever get to listening to music “flat” is with the La Scala Splits, and even then I like a little more treble, and that’s WITH a pair of SMAHL lenses and DE-120 drivers. One thing is for sure though, this hobby, or passion, hasn’t gotten any cheaper. Each incremental step seems to be closer to a week’s take home pay. Thank goodness for the other hobbyists that pass their used stuff on to a good home for a fair price as they continue their journey.
  8. Nice! I sit 8’ away from my LSI splits which are about 8’ from each other. I guess you would call it a near field equilateral trainagle. The real game changer is the distance from the back wall. I find 2’ to be a minimum. The soundstage goes deep. And as others have noted, nothing in-between your speakers. It kills imaging. In a quiet setting an unheard of 70db is engaging. A tight sub will put the cherry on top.
  9. These are sweet ...how far is Dallas from Toronto?
  10. Sooooo... what would be an ideal, or better crossover for the Chorus 2?
  11. Debate is good. Could go higher, but I think lower would be pushing fatigue at live levels. Most of the pro stuff lets the woofers exercise a little higher and I am sure there is a reason for it. I think the CF-4 crosses at 1500 hz.
  12. I’m looking for a pair of CF-5. Dual 15” woofers and the K-510 in the middle crossing at 800 hz. Anyone got the plans yet? LOL!
  13. @Outrider 6, hi James, just saw your PM, and yes there are updates and perspectives gained from personal and shared experiences. It’s unfortunate that all of the shared information isn’t usually relevant until after you actually physically experience what is being discussed. We seem to need to find out for ourselves and then make the more informed choices, sigh. The original project was with a pair of mint walnut Cornwall 2s which I very much regret cutting up. They are long gone to a very happy buyer but I hogged out a pair of “B-stock” Cornwall 1s that I got for a song some time later and have no intentions of selling. What I wound up with and what I would do with a blank slate are two different things. Since these modifications I have been fortunate enough to acquire a pair of Chorus 2s and KP-301s for comparison. Compared to the K-48s in the other speakers (K-48-E in the Chorus and the vented K-48-KP in the 301s), the K-33 in the Cornwall leaves me wanting. K-48s are tight and clean, not as low, and they really like the juice to get hammering the way they want to. I also don’t think the Helmholtz resonator / shelved port does the Cornwall bass any favours. You can alter the shelf or block a “port” to tune it but I think 4” round ports with tubes cut to the desired length would tighten up and extend the bass better. But now you are replacing the motorboard. So what I came up with as the best possible solution was a pair of Crites CW1526C woofers. The difference was night and day better than the K-33 in this application. Lower lows and more output up to the crossover to the midrange. A win/win situation. I also found some Klipsch tractrix tweeters with the puny magnet and black poly diaphragms for cheap and retro fitted them with DE-120 drivers. So now there is a tractrix horn on the midrange AND tweeter drivers. Dave A’s LMAHL lenses would shine in this (or any other) application too... One last thing was a 2x6 brace from the motorboard to the back panel and across the width of the speaker between the mid and woofer. I used a 4” holesaw every few inches on the studs to minimize the displacement. I also secured a small piece of 2x4 in the middle, vertically between the very back of the port shelf and the base of the cabinet to eliminate any vibration there. The stock B-3 crossover (600 & 6000 hz) has had the caps refreshed. I did not notice a difference one way or the other, but I used cheaper Erse and Dayton varieties. I believe a lower crossover to the tweeter would sound better (5000 hz) and is in keeping with the direction ALL new Klipsch products are taking. Having said all that, If I were to start all over from scratch, and according to my preferences there are things I would do differently. Custom made braced cabinet with 4” ports and the biggest 2” throat mid horn I could fit in a 3-way for starters. But if I was going to all that effort, I would try to design an as yet non-existent “CF-5”, having two 15” woofers with a K-510 in the middle crossing around 800 hz. That, to me, would be the culmination of direct radiating speakers.
  14. ^^^^ This, I have read it over and over again many times on this forum by those who have tried it. It is best not to skimp on the DSP. The buck seems to stop at the Xilica.
  15. The length of the port tubes is the easiest. Series/version 1 actually have length, series 3 are just holes. ...hold out for a pair of CF-3s of the rarer CF-4s, I don’t think the CF-2s will punch like you deserve. They will image amazingly though.
  16. If you can find a pair of CF-3 or CF-4 of any series for a decent price you’re in business. But those with a discerning taste will insist on Series 1. As they progressed they lost a couple Hz in the low end and the components were more economically sourced. I had CF-3 version/series 2 and they absolutely pounded. In the sweet spot the imaging of the WTW or D’Appolito arrangement really grabs you by the boo-boo.
  17. ...just reading the last few pages of this thread as I to listen to Rush’s “Red Barchetta” through my La Scala Splits, fiction is fast becoming reality
  18. ...I would like to know what a guy with this kind of equipment settled on
  19. ...I tried some acoustic foam in the doghouse, it KILLS the punch. Yet the new LS have a single piece thrown in. Probably to tame reflections. I also seem to recall reading on here that the doghouse could actually be SMALLER, someone (probably Chris A) had run some simulations on it. It is a folded horn with a definite lower limit as such, once you start playing with actual, or perceived volume it becomes a markedly less efficient direct radiator below the horn cutoff. A digital signal processor is where it’s at, so I have come to understand.
  20. It’s only 365 miles one way from my doorstep, a mere 90 miles more than my longest speaker roadtrip to date. I’ve done nine hours return just stopping for gas and a coffee (and coffee “recycling”). I’m up to it. BUT it crosses an international border and that is “messed up” right now. You couldn’t build a pair of these for the asking price.
