Hey everyone, this thread is me clearing up a few questions I have about HDC3's and HDC4's. These are the two subs in question. (so it's easy to reference ) HDC3: http://www.soundqubed.com/HDC3118-Copper-Coil-Subwoofer_p_25.html HDC4: http://www.soundqubed.com/HDC418-D1-A-_p_137.html We are talking about 18" only Whats the story behind the high Fs of the HDC'4? Was this a non broken in woofer or something? The suspension is that stiff? (equivalent HDC3 is 9hrz lower IIRC) Between the HDC3's copper coil & the HDC4's aluminum coil 1. Can I daily an HDC4 on music? 2. Is there a large efficiency difference? 3.Why is the 4's coil an aluminum winding? Just weight savings and thermal dissipation? is it worth worrying over? Required cubic feet and port area? Do they want the same? & What do they want? Everyone loves pics.. First the HDC3: Then, the HDC4 Lets see what everyone thinks. p.s. Happy birthday M5
Heisenberg posted a topic in Home AudioSo since my first box I have wanted to do an enclosure with no space restrictions. A build that focuses on cone area and low tuning. Subs are HDS200's (ordered one already to see if I like them, I will post pictures here when it gets here) Soundqubed is very vague with there enclosure recommendations and i'm looking for a more specialized design My first dilemma is with the box and is if I should go with a 2x2 pattern such as this: Or a 4x1 pattern such as this: (ported though) My only real limits are what can fit through my doorframe's in my house. I was playing with the RE Box Calculator and I can make both styles fit. I want between 12-19 cubes. (<---cant believe i'm serious with this) tuned low to 28-35 hrz It can be enormous, only one of the dimensions needs to conform to the doorframe's
Looking for a bit of advice on purchasing a new amp/amps. Ill be running a pair of D2 crossfire XSV2 15s tuned around 30hz. My dilemma is whether I would get more out of (ie more power, less rise): A pair of 2.5k amps (probably Skar 2500), bridged and wired to 1ohm each OR A single 5k amp run at .5ohm Electrical is: 2 runs 1/0 OFC (one is knu, other is memphis) and 1/0 Big 3 Kinetic HC2400 up front 3 deka group 34 AGMs in the back (55ah a piece, 750cca) 270a-320a altenator (will be added after amps) Thanks in advance for any help!
