Audioque HD3 -vs- the new HD3C

I have not yet gotten the chance to do the broad spectrum test. I'm crazy busy right now with the end of the semester at school drawing near. Maybe in a week or two.

As far as listening to them, I have made brief comments on that in various different HD3c threads, but I'll go ahead and comment here. They do have a slightly different sound than the original HD3. In some ways I feel the original is better, and in some ways I feel the HD3c is better.

On very fast transients, such as kick drums, I believe the original HD3 is slightly better. Not much though. I have a friend who is a drummer in an underground death metal band. I had him bring over a few different tracks that have some insanely fast drum lines........I'm talking fast to the point they practically blend together on most audio systems. The HD3c reproduced them very well. He was shocked at the detail and amount of separation the sub was able to maintain, especially with the amount of power I was throwing at it, and how loud it was for a single 12. He commented that his pro audio concert cabinent's wouldn't really do any better in perspective, and his own personal car audio system wasn't even close to as good or as loud. I was impressed myself, considering the nature of the sub. Typically transients are the hardest element of sound for the big "superwoofers" to produce due to their heavy cones, coils, and bulky suspensions. The HD3c overcomes those negative elements fairly well, and maintains a respectable amount of response. It doesn't sound extremely natural, as if you are setting next to the the kick drum, or the bass guitar, but then again it definately doesn't sound like a generated sine wave or a retard beating on a barrel either.

The tone quality and frequency response range on the HD3c is slightly better than the original HD3. I noticed it produced a richer sound. Particularly in the lower shelf. When the original HD3 plays the really low stuff, it tends to roll off quickly, and the sound flattens out. The HD3c maintains a full sound into the lower octaves better, and doesn't roll off as sharply. I did have to lower the LPF on my active crossover about 10hz with the HD3c over the HD3, as it botched up some of the higher bass notes a bit, but it more than made up for it in the lows. I run my LPF alot higher than most people do anyways, with it typically set between 100 and 120 hz.

Overall, I found the woofer to be very pleasant to listen to. It never screwed anything up, after getting everything dialed in. Defiantely a very good daily driver woofer for the bass heads. I wouldn't choose it for an all out SQ setup, but on the flip side I've not listened to a single woofer that sounds better, and will get as loud.

wow that was a good post.

im selling my btl locally to a member here and am thinking of picking up a new sub. the price is really itching me pretty good here, and if it has comparable low end to say, my btl or a xxx, i would pick it up in a heart beat.

1) have you by any chance used a btl or a XXX? or heard one in a daily tuned box (32-35hz). and if so how was the low end compared to it?

2) since i have no experience with this woofer i also dont know how it reacts to "lower" power levels. would it be better to run 2 15's off of 3kw or would a single 15 (or 18 if they come out in time) be better off that power? i know the last hd3's supposedly needed a little over 2kw to really shine.

 
I'm not going to go the route of comparing it with a different brand. Quite frankly, that never goes well.

As far as how much power to feed it, take your pick. It's a fairly efficient woofer, but built tough enough to take a lot of power. With 1500 watts per woofer, it's not going to do all that it can do, but it would last forever, be very loud, and be nearly impossible to tear up from user error.

At 3000 watts per woofer, it would be nasty loud, but the suspension is going to break down much quicker, and it would be subceptible to damage from user error. I ran it for several months with 4800 watts of amp power connected to it for daily use with no failures, but I was also very cautious. If I had ran the amps into full clipping for long periods of time, I believe the woofer would have failed. With 3000 watts, you would be quite a bit safer than how I was running it, so I believe you would be fine. The only advantage to running one woofer is the couple hundred bucks you save up front. The 2 woofers would be better over time.

To be honest, I think this woofer would be a hell of a buy at $400-$500 dollars. For the price AQ is charging, I think it's a steal.

yea i wasnt trying to start anything between brands. i was just trying to see if i could get a comparison to at least hint at an idea of low end. you compare it to the hd3 lowend...but i never heard an hd3 lol. i figured giving we both have explorers, it would give me an idea of what to expect. but i do know why you prefer to not compare woofers.

And this is why I ordered one wednesday. Hopefully it will get here in the middle of next week sometime. My last class for the semester is next tuesday so hopefully i get it tuesday or wednesday and be able to throw it in my car saturday.

I ordered the 15 D2 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

hey Jeremiah25. i was doing some research and i found this post by you

http://www.caraudio.com/forum/showpost.php?p=3704282&postcount=761

now when you said that you liked that setup as one of your favorite daily setups, any chance i can get some info on box size and tuning? did you just go with the standard 4.5 cubes thats recommended for the HD and a 34hz tuning (which you said seems to be the best for daily in the explorers) or did you tighten up the box a little bit and use a different tuning?

 
ignoreme, I would say 2500rms per woofer would be right about where you would want to be, but they dont need tuned low, I would say 36hz+ my hd3 tuned at 40hz+ nailed the lows rather well and acted as a good dual purpose box (daily driving and competition) after reviewing more and more changes from the hd3 to the hdc3 I think the hdc3 will with stand alot more damage to be honest, the hd3 did have a fairly weak cone comparied to these others using carbon composite, kevlar composite etc...paper just wasnt cutting it, I noticed the hdc3 has double stiched surround, and a reinforced cone, which should really add to the strengh of the woofer overall, either or it looks to be a pretty good woofer expecially for the cost. I trust in jeremiahs testing and he thinks its a pretty good woofer as well, so hopefully we will get more people doing reviews to give others an idea of this new found beast...

That box was about 7 cubes net. It was as big as I could possibly build it, fit everything I needed to fit, and keep it below the window line in the back of my explorer. To be honest, I really don't know what it was tuned at. I did some weird stuff with the ports on that box, and I don't know how it affected the tuning. Most likely it was about 38 hz.

With 2 Z1's it would do a 154.3 legal dash, with 2 NSB 90's in street C.
