What's a good 18 inch sub

[Guest]

I got rid of two 15 L7 s for two 18s obsidians and i am very impressed great subs for the price and dont let the 2.5 coil scare u off they can handle plenty on power

"plenty"...its just a 600w driver. idk why people are thinking these woofers are like new-age sliced bread. no matter what a company does to make it "run better", the 2.5" coil wont be able to handle the power that a 3" can. physics dictates that it wont happen.

and again, for the budget money OP has, 2.5" coils are useless in my eyes. if he only had a grand to spend, i'd say go for those types of woofers.

I'm new to all the technology about subs now what's the deal w the voice coils

They can easily take over 1000 watts on a daily basis, plenty of people already proved that including myself

the bigger the voice coil, the better the heat dissipation due to the larger surface area. bigger voice coils can handle more power. the baddest 2.5's are limited to like 1000rms. 3's can handle up to like 2500rms usually. 4's are slightly higher.

edit: these are kind of rough figures, so dont take them to heart. just gives you an idea of how typically the bigger the coil the higher the power handling.

I appreciate all the advice

two of these in D1 configuration. http://www.soundqubed.com/HDC318-Copper-Coil-Subwoofer_p_25.html

one of these. http://www.soundqubed.com/Q1-3500D1-Amplifier_p_32.html

$1,417. leaves 1,600 left for electrical upgrades and wire and shit.

edit: mind you, you dont have to go with what i say. its just a recommendation. but the performance to price ratio from those products is through the roof (meaning good, not bad lol) in my opinion.

or you could do 2 hdc4 18's http://www.soundqubed.com/HDC418-D1-A-_p_137.html they handle 2000w rms which is twice the hdc3's and have 4 inch coils instead of 3 inch

and the q1-3500 http://www.soundqubed.com/Q1-3500D1-Amplifier_p_32.html which puts out 4300w rms at 14.4 volts 1 ohm

hdc3's are underrated...by alot. they WILL handle a 2200 all day every day. assuming you dont clip them a shit ton.

hdc3's pair perfectly with the 2200.

hdc4's pair perfectly with the 3500.1.

edit: hdc3 is like 50lb. 1000rms my ass LOL.

coils can have the same amount of winding and be half an inch smaller,

but the OP wasn't looking for some monster subs. I say the SA line from Sundown is a FINE woofer and it will still leave dude some room to grab a good alt, wire, alt etc...

he says he wants it to hit hard. so why not go with big woofers? around 150db should be good enough for him.
