HDC's - My Review

[mlstrass 5,000+ posts]

Been running HD's for around a year now and recently swapped in a set of HDC's. Picked them up blown for a good price and slapped on fresh recones. Was my first time doing that and I must say it was very easy. Other then getting the old glue off the surrounds //content.invisioncic.com/y282845/emoticons/furious.gif.fc81ca146dbff91fede3ed290dbc4f4c.gif

Per AQ's instructions I broke them in for about 12 hours. Low to Med volumes, nothing with real low bass. Gave me a chance to see how the SQ compared to the HD's.

Remote gain is set up so that 12 is full tilt, so I varied between 4 and 6 for the break in period.

Played a lot of metal with fast kick drums and they sound quite accurate with nice punch and kept up no problem. Some of the death metal stuff is insanely fast and they never seemed to miss a beat. I ran RL-P's before the HD's and they played very accurately, but I found the sound almost dry or lacking impact at times.

Also did some blues and jazz stuff with an actual upright string bass and the notes sounded like they should and blended well with the rest of the instruments.

Did some 80's R&B and hip hop, the stuff with the old school clean bass beats in them. Sounded **** good, tight and clean with nice punch on the harder beats.

When dialed back you could easily mistake them for a pair of 10's output wise. They add just enough bass to compliment my front stage, and the bass comes from the front as it should.

Tonight I finally got a chance to lean on them. Each sub is powered by a pair of SAZ 1500D's strapped at 2ohms, so around 3k per sub.

Played some metal full tilt and the kick drums smack you in the chest. No more bass from the front as the back of the seat feels like someone is kicking it and makes you VERY aware of the beasts behind you. Hard to tell by ear if they're louder then the HD's, especially since I haven't heard anything loud in over a week while breaking them in. They still play very clean at LOUD volumes which is what I like the most.

Now the most painful part, but what most on here will want to know. I reluctantly played: hypnotize, late night tip, and the snoop/akon "i wanna F you" remix. Played them all in a row full volume and got NO smell from the subs. Not sure how long they'll take 3k each, but that was probably 12-15 minutes of STUPID loud and more then I can take of that music.

Lows were insane and shook shit in my car that never rattled before. The bassline in the snoop/akon song buzzed the shit out of my ears, made my nose itch, and reminded me of why I don't listen to that type of music. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

At very loud volumes they won't be confused with a serious SQ sub, but they will still play very clean and insanely loud. No boomy or muddy sound at all. Add in the TONS of deading and work I've done to eliminate rattles and they're almost deceptively loud as all you hear is the bass from the music.

I plan to get them metered next week to see how they do against the HD's. I've heard around .5 to 1dB per sub which wouldn't **** as I'd like to hit a 150 @ 34Hz since the HD's got me so close. Won't scare any SPL guys, but it does all right for a daily driver that was built to sound good //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Yes, copper coils. What diff do you notice? I plan to run 4 eventually off the same 4 1500D's, so copper will be perfect for that power. I'll just go easy on them for now //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I noticed how much smoother and quicker response between the 2. Although it could have been mostly the enclosures I heard, the copper was an overall better sounding.

and I heard how 1500 for the copper coil hdc3 is perfect..... the hdc3(copper) i have seen on a sundown 1500 barely moves and begs for more....

I assume that as they loosen up some the sound will get even better. Since I listen to pretty much everything but new rap SQ is important to me, but I still like it loud at times...

Forgot to mention that the subs have NO mechanical noise after a proper break in...

I've free-aired a hdc3 copper on 1000w or so and the sub was laughing at it. The coil wasn't even stinking.

Got some CA guys stopping over tonight if you want to head up...
