power, this sub moves so much air. the spl is so crazy. It sounds like 3 12''s or even more. sound q isn''t bad either.

sometimes too powerful. i would only get this speaker if i wanted mad bass. It''s a little pricey too.

i have used the hcca 10 for a little while now and i have been more than impressed with it. The air that just the 10 inch can move is just insane. even though this sub is a competition speaker, it also has sound quality. when you put that with it''s off the hook power, you can''t be stopped!!!

this is the sub to have, my friend and i hooked up ONE hcca 12 in a vented box to a xtreme 300 at 4 ohm and the sub is getting 420 watts almost 200 under its rms RATING and we have hit as high as 143 dbs thats right one 12 hit 143 DBs , my friend was so impressed he sold all four of his polk 12s to get TWO hcca 12s and hes going top run them on one xtreme 900 per sub that will be about 1000 + per sub we think " we know " we will hit over 155 DBs with ease . check them out they are awsome spl or sq they rock.

the 10" hcca or the 15" hcca all other brands claim to be the shiznit but fall short when you put them on the line.

one sub can hit harder than most other two sub combination. Look badd as hell. Can produce really low bass with good soundquality

need a lot of space. make you go deaf knock the crap out of your car, leave you with ears ringing and nauseated

I bought two of theese things about a month ago from a dealer on ebay. These things freakin pound. They are tearing the piss out of my car. They are in the trunk of my taurus sho and they are moving the rear shelf almost two inches. I am using two hcca and two sony explod amps rated at 1000 rms each with ported boxes.

Looks mean as hell, Thick rubber surrounds, clean sub, huge magnet.

Power handling, You would think a sub as big and as mean looking as this one would handle more power. Max is like 1200 watts peak! Or at least that''s what they say. Can''t make box out of 3/4 inch mdf, have to use 1" thick because of the big structure.

I heard my local car audio shop''s Ford pick-up truck and that thing HITS HARD!!! When I was sitting inside, he played one note and it was vibrating my head and my clothes were moving from all of the air it moves. The guy told me that they put a 1" thick mdf board on the roof and it still flexes. It has 4 12" Orion HCCA subs and 4 275g4 HCCA amps with 4 batteries to each amp. They are hitting around 157db and no one can touch them except for the guys with 12 12" subs or more. That speaks a lot for these HCCA 12''s. If you want a mean sub that will give you hard hitting bass, high power handling, and an intimidating look, then these subs are for you!!

It pounds ! Good price for what your getting I paid more for 2 mtx 8000''s in a box and they dont compare to this 1 sub

Only thing I can think of is the price but look around they can be found for like $300 for a 12 in sub and $360 for a 15 in sub or cheaper used. If you wanna play you gotta pay =)

I recently bought an Orion Hcca 15 in sub my god man it pounds ! I was showing my uncle and the neighbor 2 houses down asked if I could turn it down. I had 2 mtx 8000''s before and they dont compare to this one sub. For those people that heard bad things to say about it they probably werent running it according to what orion recommends. Ported ! big box as well. I am running a single orion xtreme pro 1000 to it and it vibrates my whole car.

they are the loudest 12inch speakers i ever had or heard. they are dual 2ohm speaker which lets you get more out of your amp. they handle as much as 1200watts.you could easily hit in the 140s and up in comp.

there are none the speakers in its class are over priced so the price isn to bad.

i give these speaker a 5 rating because out of 6years of hearing and having different systems these 12's are the best i had so far and i only have about 1/4 of the power it needs on them. I RECOMMEND THAT IF YOU DECIDED TO GET THEM AT LEAST PUT 1200WATTS ON THEM.

Very loud. Hit with gut rattling bass. Definately a top sub.

Price, as most other people have mentioned. Also, The sound quality is not as good as I had hoped for the price (MSRP, not what I paid =p). And unfortunately, the subs hit a bit on the slow side. And, requires way too much room for a ported box =(.

Definately one of the top subs. Really treated me well, and hits REALLY hard. Only, after buying them, I found myself considering buying a pair of Eclipse 10's... they just keep the beat moving a bit faster. Then again, that's not the point of the HCCA's. They have one reason for existance: shake you UP. And they do that, one way or another.

This sub hits very hard. It rattles your brain to death and I only have about 400 watts going to them. I have one 12 and I have a clarion 400.2 on it and it hits hard. I only paid 125 dollars for it on ebay. and it was a remanufactured speaker and does good.

Break in period.

It is a very good sub but I only paid 125 dollars for it and wouldnt pay 600 for nothing and if you would like to get the deal I got just buy off ebay its safe and easy.
