This is not from a soundtrack but a live album. It is Hugh Masekela's "Hope" album. It was recorded in 1992 or 93 at the Blues Alley in Washington, DC. The track in question is the last on the album; it is called "Stimuli (the Coal Train)". It lasts about 10 minutes and is probably one of the most dynamic recordings I've ever heard.
I start it out at about 68-70dB's and it goes to 102dB. This happens about three times during the course of the song. There is some drumming that is mainly toms and bass drums that keep building, and building, and building, until you think that they can't get any louder, and they build again.

I have overdriven both C1's and C2's with this track. Pop!
But I have never been able to "pop" my Special 25's. That 8" Evidence driver is so robust.
And no it is not clipping (I have 400W mono-blocks).

I've heard this track on both digital and analog, it super pops on analog even more than on digital

When I referenced some car audio amplifiers, I wasn't referring to the experience in the car, nor want to get into an argument about car vs. home audio. I was just expressing my displeasure with a lot of home audio equipment (including stand alone amplifiers), and that I have heard better designed and sounding equipment built for a car.

By the way, anything JL Audio makes for amplification doesn't compare even remotely to the products I am referring to.

We'll seen how the SR7007 performs and go from there. There is always the option of using a 12v power supply and bringing some high end mobile audio into the home.

Sqoverall: Now remember this was years ago when I was talking about JL Audio Amps, I know their is much better stuff back then and now, but at the time it is what I could afford! Not trying to argue about anything as in this business as I stated comes down to personal preference and many other variables and that goes hand in hand with car or home audio. On another note; some of the Brax stuff I heard with Dynaudio were pretty sweet and the ARC signature stuff was nice, just wish we would have had some of the betters stuff back in the day! Just curious what your comparing when it comes to home Audio Amps? Some of the good music only Amps or Int. Amps would be on par with some of the best Car Amps, depends on what your using as a comparison.

Hi people.

Recently I posted about the option to buy a Dynaudio Sub500. I wasn't sure whether I should pull the trigger on that one, or go the DIY-route, since I already had an elaborate (but complicated) design. For the asking price it seemed like a good deal, but I was able to pay even less. Given the state it's in (about three years old, seemingly very few working hours and looking practically new) it was an absolute steal. Needless to say, I bought it. And I love it! Together with my Special 25's, I can safely say that I have only once heard a setup that sounded more complete and coherent. I could probably make it even better with a better amp, but that's another story.

I do, however, have a few questions regarding placement and setup parameters of the Sub500. Especially to those who use it with Special 25's or similar monitors.
I currently have it positioned directly to the right and slightly behind my right speaker, due to room constraints. The driver faces inward, not towards me. The x-over on the sub 500 was set to full range, phase at 90 degrees. The crossover in my AVR was set to cross to the sub at 40Hz, the S25 running full range. This way, the sub will only work below 40Hz, unfortunately also heavily filtering LFE tracks. This works pretty well for most music tracks, resulting in some minor loss of perceived energy at around 40Hz with some music material. Setting up my AVR to cross over at 60Hz results in more bass-presence (no or less loss of energy around 40Hz), but also makes the bass sound somewhat sluggish or bloated. Turning the sub volume down helps somewhat, but then the extreme lows suffer from that. Even though my overall sound is great, I keep having problems getting seemless integration with a sub. My last two subs were B&W ASW610 and Adam Sub10mkII. Both had trouble integrating well.

Is this really a matter of tweaking parameters, or more a problem with placement? When crawling the floor with the Adam sub in my lisening position, I got the loudest deep bass (and best overall sound) in the corner the sub is now in.

What can I do to further improve the smoothness of the ultra low end (apart from purpose-designing a room for it )?

I'd like to hear from you sub woofer users! Thanks!

James.
