Car Forum / Driving, Maintenance, Tuning / Car Audio / February 2004My bright Dynaudios, more
I've been told that the Dyns are very power hungry, and I've had a though - I'm powering them with a Zapco Reference Series 350, which should be making about 100 watts per side. Is it possible that the problems I'm having are the result of not having enough power on tap? I am running mine (240 gt) off of a 4 channel mtx 4200x bridged * 2 at 110 watts per channel per mtx test that comes with the amp. They sound fine once I set the tweets of the -2db position on the passive crossovers. How bad do yours really sound? Like really bad or just not perfect but that means really bad to you? . I run off an Alpine 7995 HU with great sound. I don't think more watts would hurt though. I am gonna try to run them off my mtx 2300 sub amp which is like 300 watts per channel to see how they sound. If it doesn't seem like too much juice I may replace the amp with another 2300 or maybe something in between. I'll let you know how they sound. -z > I've been told that the Dyns are very power hungry, and I've had a though - I'm > powering them with a Zapco Reference Series 350, which should be making about > 100 watts per side.

But with bad stuff, they REALLY sound bad. "Steve Grauman wrote: " On good recordings, they sound great. But with bad stuff, they REALLY sound bad." If you're playing "bad" stuff, then of course the speakers will sound bad. Tony What's more likely? That an all-powerful mysterious god created the universe and then decided not to give any proof of his existence? Or, that he simply doesn't exist at all? And that we created him so that we wouldn't have to feel so small and alone. -Eleanor Arroway, Contact Tony what amp/ how much power are you running? don't you have the 8 inchers? " Z. Gluhak wrote: "Tony what amp/ how much power are you running? don't you have the 8 inchers?" Yes, I have the 360 set. I'm running active. I'm using a Phoenix Gold ZX475ti to power the tweeters and midwoofers, and half of a ZX450 to power the midranges. Of course, this gives me total control of output & xover settings. In addition, I'm using a 30-band EQ. I've got WAY more power than I'll ever need. I believe the amps are "rated" conservatively at 75W/channel. I think my amp gains are turned less than a quarter of the way up. For what it's worth, I found the passive Dynaudio xovers to be very disapointing. They sounded very detailed at lower volume, but when you really cranked the power on they lost their focus and....well, I'm not sure what words to use, but they sounded "grungy". By eliminating them altogether and running my system active, it sounds 100% improved. The only problem I've encountered is that I've found I have too MUCH control over everything and I'm always screwing around all the different settings and second-guessing myself. It's like driving a car with 60-way adjustable power seats. You can never seem to be perfectly comfortable!! Tony  SignatureWhat's more likely?

One reason why I still haven't decided to add an eq to my system. Nick TheBIessedDead wrote: "One reason why I still haven't decided to add an eq to my system." Yeah, I hear ya. I've still got so much to learn. Unfortunately where I live there aren't many people with systems, so everything I learn is self-taught. It's a long process. I'm just starting to be able to say stuff like, "It sounds like I need a little less 2KHz, or a little more 100Hz." It's kind of like giving someone a BMW M5 that doesn't know how to drive it to it's full potential, you know? I mean, it's a nice car, and they can probably kick some a.s in it, but without some proper driving training... Tony SignatureWhat's more likely?

Haha Believe me, I know where you are coming from. People's idea of a "system" around here is being able to rattle windows as they drive by. SQ is an absolute unknown. Most everything I've managed to learn in the past few years is strictly due to RAC, and internet searches. I too have a long way to go, but I'm gettin there. I do feel though, that if I added an EQ I might be just too tempted to play with it. These past few weeks, I've forced myself to set my deck EQ to flat, and listen to it like that... I'm getting pretty used to it, and I'm starting to think maybe I don't need an EQ at all. But then, as people have mentioned, certain cds just need a little boost/cut in certain areas to please me.

I have the 7 inch mids from the 240 set, but our tweets are the same. Can someone give me the "lay-man's" way to fix this problem? If all I need to do is go to a better crossover, I'm all for it. > >For what it's worth, I found the passive Dynaudio xovers to be very > >disapointing.

If all I need to do is go to a better crossover, I'm all for it. You won't find a "better" crossover. You may find crossovers that make the system behave differently. Whether or not it's pleasing to your ears is impossible to predict. That's why biamping with amplifiers that have built-in continuously adjustable crossovers is often a good idea. Or even adding external active crossovers. The mystery revealed: Dynaudio's are like having sex in a bright room, with no covers, and no beer goggles. Everything is revealed, for better or worse! I had to take it one step further than the -2dB setting: I added a 2ohm NON-INDUCTIVE 10-watt resistor to each tweeter where the speaker wires connect to the crossover boxes. This made all the difference in the world!! If you have your tweeters up high, you may require as much as a 4 ohm resistor. I would instead highly recommend putting the tweeters in the kick panels, but close to the door speakers. Doing this, plus adding the 2 ohm resistors, will result in a remarkable improvement. It's possible. So have you tried repositioning the tweeters? Try something off-axis.
