Single SR 10 sub. Which amp?

Toxis

I'm considering either the Xtant 6.1 (600w mono) or the Diamond Audio D61000.1 (500w @ 2ohm) to run a 4 ohm DVC SR 10" sub. I'm considering the Xtant for the SQ and a tad more power but it's also gonna cost me about $100-140 more. Is it worth it??? What do you guys think? I want great SQ but the potential for some output. OEM deck BTW, nothing aftermarket.

C500.1

Of course the best choice would be the 500.1

BUT, Xtant effing rules!

If your choice is between Xtant and anything else, get the Xtant.

Ultimate build quality, tons of clean power, a host of tuning features and very cool looks.

I could get the Polk 500 but I have a feeling they are going to be remodelled fairly soon so I'm not sure about that yet. I can get it for $100 less than the Diamond and $110 less than the Xtant. My prices were wrong earlier (off top of head, not actually looking at my prices). The Xtant is $10 more than the Diamond. I could get the Diamond and a dual 2ohm sub to get a full 1kw. Hmmmmmm

Xtant

I think either choice would be a good one.

Toxis

so would you rather put 500w to it at 2 ohm or 1k at 1ohm? I'd have to order the dual 2 ohm while we stock the dual 4. I'm leaning towards the Xtant with the dual 4. Building a box that sits "sideways" and is mounted to my rear deck. Then have it fill a chamber that is now using the OEM sub cutout as a way directly into the car. Have it sealed off so the trunk gets as little to no sound as possible. I'm sure 500w will be plenty for that.

If placed in the proper enclosure, 500 watts will be more than enough to get the sub going.

They dont have a dual 2 ohm SR sub. Its either single 4 ohm or dual 4 ohm so the 1 ohm operations aint gonna work unless you buy a pair of DVC subs.

The Polk C500.1 will make 600 watts RMS and the Xtant will make a good bit more than 600. Id say youd be closer to 700 with the Xtant.

1996blackmax

No need to get close, as you will get all the performance you need before giving that sub 700 watts.

Toxis

word up... now I just have to fight the urge to upgrade the fronts.

That's probably not a correct feeling... just a subtle hint

bknauss

And Polk > Xtant. Its been proven thousands of times!

Are there any plans maybe in the somewhat near future to release a line of amps that is styled moreso to the SR line than the momo?

i have the sr124-dvc and am going to use my zapco c2k-3.0 rated at 600 watts into 2 ohm bridge. in real life it puts out about 700 watts. its expensive, but they are rock solid amps with a damping factor of over 1000 to really control cone movement.

I too have amplifiers with very high damping factors .

Toxis

Damping factors... great on paper, worthless in real life.

Couldnt agree more!

bknauss

Damping factor is actually important... but its unimportant to most consumers since it doesn't generally affect anything out on the market and there are too many ways to post its value.

MacLeod

Isnt it like THD specs in that while true .004% is better than .04% but it doesnt matter because you cant hear anything below 1%?

I kinda figure any damping factor over 50 or so and youre fine.

1996blackmax

I will still stick with my Arc amps .

You're on the right track. But 50 measured which way? There's the problem right there... hard to quote a number that means anything when there are different ways to measure it.

MacLeod

My understanding is that its measured by the load impedance divided by the amps internal impedance?

If thats the case and most amps that Ive seen specs on have around 1 ohm or less internal resistance and a typical load is 4 ohms, a typical amp with these numbers would have a damping factor 4/1 = 4! Maybe if the amp had .05 internal impedance youd have 4/.05 = 80. So basically an amp would have to have an insanely low .005 ohms internal resistance in order to have an 800 damping factor! And to my knowledge, there arent any amps with that low of internal resistance.

Isnt this right or have I missed the boat completley?

Remeber, I have an EXTREMELY limted understanding of this so be gentle!

this explains alot about the damping factor subject. i didnt know speaker wire size can play a big part in damping factor values. i dont know anymore but the amps i like and buy always had very high damping factors, like zapco and u.s. amps. i just like quality amps, buy it once and it lasts.

killerb

heres another good one.

Good links.

I think I understand it now.

killerb

yeah i finally do to. there is virtually no change in decay time through a wide range of damping factors which is surprising to me. good info for all.

joeaudio26

well xtant is consider high quality stuff the price of it says alot and they did their research in car audio its ur choice.

killerb

the new xtant isnt of the same quality as the oldschool xtant.
