  1. @pbphoto Yes, I'm using the proper subwoofer output on the receiver. Since I use the YPAO, it makes sense to let the receiver handle filtering and relative volume levels. Running YPAO was the first thing I did after installing the new speakers. I usually re-run it after any significant changes in positioning, since it's pretty quick. Front left/right (150M) are close to the wall, up near the ceiling; one is on a tall and narrow bookshelf, the other is supported by a bracket on the wall. They are angled left/right towards the couch in the center, but they are vertical; I am NOT leaning them forward towards the couch. I have removed the base that comes with these speakers - they are actually leaning back when sitting on that base, IIRC. Center (250C) is below the TV screen at knee height. It's sitting on a horizontal shelf below the screen; I am NOT angling it up towards the top of the couch. Subwoofer is on the floor next to the TV on the right. Not quite close to the wall, maybe an elbow length from it. That place seems to provide a fairly uniform level of bass in most places in the room (more or less). Despite the vast differences in height, center and FL/FR sound about the same. There is some difference, albeit pretty small, when I sit down on the couch vs standing up, as I am moving closer to the axis of one speaker or another. But I really have to listen for it to tell. The sound changes a little when I move off the couch, way out to the right, but again it's not a huge difference. I'll check all the sound settings on the receiver again. Maybe something escaped my attention.
  2. I've no doubt it would work. But it seems, I don't know, improvised. I've just noticed what seem to be Allen bolts (or similar) on the panel where the wires are connected. If I remove that panel, is the crossover located behind it? Once I have access to the filters, it should be trivial to test a few resistors with the tweeter. Excellent. That would preserve the impedance. It's better than my single-resistor ad-hoc scheme. Thank you for the idea. It's been many years since I've done circuit design. Obviously there are many things I've forgot. So I've noticed. I'm not a hater. I just think the tweeter sound is a bit more conspicuous than what my ears would expect. The bass and the mid-frequencies are balanced with each other pretty well. That was the case also with the old speakers. It's the treble that's above both mid and bass, with the new speakers. Raising the bass would make the whole frequency response V-shaped. I don't like that sound. I'll give it a try tomorrow, but I'm skeptical. Yep, I'm aware of that phenomenon, I see it all the time with my headphones. And yes, the new speakers are not always too bright. In some cases they sound close to normal, just leaning a little forward. But in most cases they sound too much TSSSS, TSSSS. Like I said, I own a pair of Grado phones, and these speakers sound just like that. Very detailed and revealing, but tiresome after a while, and artificial-like. The kind of sound that makes you hate cymbals. I would also rate it a bit... I don't know... harsh? Metallic? Perhaps I'm imagining things. I bought a Teac av receiver, with speakers and subwoofer, the cheapest thing at Costco in 2000 A.D. The subwoofer died first, many years ago, so it got replaced with the Cambridge Soundworks cube (which is still very good). The receiver started conking out gradually, so I've replaced it last year. And a few weeks ago I decided I hated the remaining speakers - little cheap boxes whose main design constraint was cost effectiveness. So yeah, they were bad. One of them was buzzing at high volume. But I'm not a stranger to high quality speakers. I had a mini recording studio at home 12 years ago or so, complete with mixing table and studio monitors. I still remember that sound. It was extremely detailed, but not fatiguing, and flat enough and neutral. And, of course, I am very familiar with the tonal balance of several species of high end headphones - but one could argue phones and speakers are too different for a direct comparison (personally I'm not sure the differences are too radical for a comparison to be allowed). I know flat sound when I hear it. This is not it. That's what's bothering me. Even with all EQs and tone controls turned off? Well, I guess it's possible. I'll keep that one on the list as I'm trying different things with the whole system. The headphone output on the receiver seems very neutral. Even in my best phones, I don't really have any major complaints there.
  3. I bought a pair of Klipsch RP-150M and an RP-250C to replace my very old and pretty bad speakers. These are the first Klipsch speakers I've ever owned. The new boxes seem good enough to me. I run the bass through an old Cambridge Soundworks cube, so I can't speak about that. Mid frequecies are decent. But there's one thing: the tweeters seem a little shouty, a little too loud. I've posted about this on another forum and about a million people replied it's a known problem. Well, I wish I did more research. I just didn't know. But I want to keep these speakers if I could tame the tweeters a bit. Would it be okay to open the boxes and place a resistor in series with the tweeter? Perhaps I should try different values, like 1 ohm, 2 ohms, etc. The resistor should be able to dissipate several watts. Or is there a better procedure for this? I don't want to mess with tone control in my Yamaha RX-V381 av receiver. I like to keep things flat at that level, and I usually disable all effects, equalizer, etc. I also use the headphone output on the receiver, and I like the sound I get from it now. I really do believe the tweeters are a little too loud, call me weird but that's how they sound to my ears. But I like everything else about these speakers, so that's what I want to fix. Is there a guide somewhere online for how to open these boxes?
