It will be fine. 2 ohm stereo load is the same as running 4 ohm bridged.

They're ugly step children only loved by inadequate amps.

Keep your D4's on your side of the tracks and their won't be any probs, broseph....

The higher impedance actually requires stronger amps but .... okay. wink.gif

Going dual opposed, it makes sense for me to go D4s, with the option for another dual opposed D4s later off an EP4000. Plenty of power for these. I'll never need to hit over 100db much throughout the frequency range anyway. I don't have the place for 120db of awesomeness, yet.
post #1026 of 2212
The D4s could be wired for 8 ohms or 2. So obviously running Dual Opposed with a sum total of 4 ohms would work bridged mono on many amps, or running 2 ohms per channel. Conversely The D2s could be used stereo on the same amp.

I guess it just depends on what amp you are using and how many subs you want to run. Me, I want to run 2 subs at 4 ohms per channel, I know you get more power with 2 ohms but you also get more heat and distortion, and I figure even at 4 ohms most amps will provide plenty of juice.

You don't know most on here very well apparently. biggrin.gif

My drivers were delivered today. I assume I should test them out to make sure they all work. What is the best way to go about doing that? Some of the KC guys were talking about using a 9 volt battery - is that the way to go? If so, how does that work again?
post #1029 of 2212
Just connect it up with the positive and negative ... or whatever and it should sorta make a 'pop' sound and move forward or backward.

Oh and PICS!!!

I fixed your link smile.gif

Nick told me in advance they would be shipped in an Obsidian Audio box (same owner). Probably didn't have any SI HT boxes printed yet.

Although they might look alike, the voice coil and the suspension stifness and such is what makes it the SI HT and not your typical car driver. It digs deeper!

Keep cranking,

9V is a good way to see if the sub is wired correctly internally(+ is actually the + and - is actually the -). When you put the 9V to the sub(+ to+ and - to -) it should pop out. If it sucks in then it is reversed. You should also put a 10Hz sine wave through it and make sure its not making any unwanted noises at decent excursion levels.

Yeah, thats what i was thinking. 1" MDF, external dimensions, since its downfiring id probably want to sink the subwoofer either 1 or 2", but im not *as* concerned about height.

As has been said, the HT18 is related to the Obsidian but it is much more compliant, the VC has been modified and the shorting ring has been added as well for additional linearity. Really, the only things similar about them is the "looks"
post #1036 of 2212











These things are light! Well, light compared to the only other 18" driver I've ever picked up, which was the ported Captivator driver.

I checked them all with a 9 volt battery and all were wired correctly, and then tested them with a 10hz test tone turning the volume up to around -8. Lots of movement, very smooth, dead silent - no rubbing or scraping noises. Nice!! smile.gif Sad thing is I had to box them back up while I wait on the flat packs.

is he going to use the 4.5 sealed or what box is carp going to use?

You look small compared to that driver...I know I posed myself beside my 8. Perhaps the worst mistake I ever made to grace the interwebz...

For this driver, 4.5 is happy, per driver. at 600 watts. You want to go higher? cut the box smaller and give it about 1,000 watts. It will still be happy around 3.5-4 cuft per driver

Haha, I figured if you put a pic up with you with your drivers I would do it too.

To get an idea of scale, I'm 6'1" 170.
post #1047 of 2212
finished dual opposed pair up yesterday. really happy with how they turned out. These pics are all in my thread but i figured i would post them here as well. listening impressions to come. I like what i hear so far.



post #1048 of 2212
Nice Brian!! Those look great, can't wait to hear your impressions of how they sound.
post #1049 of 2212
WOW!!! Brian,,,

What a beautiful job on those...They look AWESOME!!!

GREAT job!!!
Thanks for sharing...
post #1050 of 2212
THANKS!!!!!!

I did a little more level matching and some testing. Im sure they arent broken in yet, but heres my initial opinion:

I just watched the final battle scene in The Avengers. Also the Lightening strikes and Pods Emerge from War of the Worlds. Both scenes flickered the clip lights regularly.......I have never been more afraid of breaking my house or having the cops called on me!! And thats with only 1 amp, 300 watts per driver. I cant wait to send 1000 watts at each of them!! Actually, im kinda nervous........
