Hi, i am thinking about purchasing 1 or 2 12" subs, i seen a vid of these Power Acoustik 12" FUBR-12's and they seemed to be preety good, anyway seems like there crap, i see alot of car subs for under 150 pound, is there any decent subs for around 150 pound on www.caraudiosecurity.com, not really botherd if the size is 10 or 12 but would like them to be the best for my money, i know you think its wierd putting car subs in your house, but it's only untill i get a car and i like lots of bass anyway. Oh and what about a Amp too to power them off, is there any around 50-100 pounds?, i will get speakers later, for the mean time i want to connect the subs up to my computer for the bass and i will be using my logitech system just for everything exept the bass, sorry if it's stupid trying to get some subs for that cheap and an amp, i dont know alot when it comes to audio stuff.

Just buy some subs that were designed to be used in a HT application. Car subs are generally 4 Ohm or lower and rely on cabin gain from a car, which means you'll want a decent amp with them when you put them in a large room. You will also need an appropriately sized box to put them in. Drivers for HT are usually cheaper and just as good.

.....Willhub, since the Behringer A500 bridges to 440 watts at 8 according to WmAx, I'm going to pull the referral to use one bridged on 4 ohm subwoofer elements that are rated at 400 watts....I suggest you use only one A500 for both subwoofers with the dual voice-coils of the Infinity Kappa Perfect 12D's "NOT" paralleled....yes, using only one voice coil on each....you might as well get the model that has dual voice-coils since there's no price difference, but only wire one of the voice-coils with the A500 amp used in stereo pushing both subwoofers....I strongly suspect you'll like what you will get....you may get a different amp in time that would support both voice-coils paralleled.....

Hmmm 400W rms dont seem that powerfull, i have seen some subs for about half there price that are about 700W RMS, i dont understand, so i get 2 infinity subwoofers, 2 of those amps (why not one amp) 2 or those boxes then i am all set?

.....yes, Willhub, one amp for both would be fine, and don't parallel the dual voice-coils....all you need then would be a mono signal to both sides of the amp, and an adequate gauge of speaker-wire from both sides of the amp to the enclosures......

.....these are special, Willhub....coming from inside the type II sealed box, they will put out some very good CLEAN sub quality....but hey, get some 15's and boxes to match if you want to .....

15's will be a hell of alot more i bet lol.

I dont understand, what do you mean by dont parallel the dual voice-coils? and whats mono for, cant i have stero? what if i was wanting to watch surround sound with my z5500 speakerrs and have those subs connected to the comp, how would i set em up for surround sound?

(I found this one, only 99 quid, i can go up to 150 quid http://caraudiosecurity.com/shop/product/products_id/1323.html, might spend 200 quid on 2 if there ok?

Or this one? http://caraudiosecurity.com/shop/product/products_id/1249.html

Were it says sensitivity, 89Db is that the max it can go?

As of now i have found no way to ad a sub to my logitech z5500 system due to the proprietary way it is put together.

You cannot simply replace the sub, because the sub holds the amp and some other important things. You cannot just add a sub with speaker level inputs, because there would be no bass due to the fixed crossover. the only way i can see using a sub with the z5500 system is simply using the speakers with a seperate reciever. And honestly they are not worth the trouble.

400w isnt that much?

Man, I remember my Logitech 70w system and its sub could shake my room.

My 125w 3 way's shake even more.

.....Will, if you parallel dual voice-coils on a car subwoofer element that are rated 4 ohms individually, you then present a 2 ohm load to an amplifier section that must be rated at 2 ohm stable....if you then bridge the amp, the amp must be 1 ohm stable, and those are pretty much only found in VERY expensive car amps, and you would need two....you could do this with a couple of 110/120 volt to 12 volt DC converters, but there goes your cost even higher....
willhub said:
and whats mono for, cant i have stereo?
.....sure, you can run stereo signals to two subs, but that is not the usual practice, but if you want to try that, go ahead, and you can do that even with commercial subs....
willhub said:

.....Will, you're not going to get surround sound except with a minimum of four full-range speakers in somewhat of a four-corners setup....I would advise two subs to be in the front soundstage equally split apart from the middle to taste, supporting the front soundstage......

.....Will, I'm going to change horses in mid-stream with you and say what you need is two 10 inch commercial powered subs somewhere in the amount of $125-$175 apiece....two will sound like and have the effect of three if placed right, trust me.....my application of car subwoofers and boxes is for 5 bass seperates covering the range of about 250 hz down to 50 hz, with honest-to-goodness home subs then taking over from 50 hz down and spiking the football....your costs are going to go WAY over $300 bucks to probably about $800 if you end up trying two car subwoofers, two boxes, a decent amp or amps to power them, and some means of an active eq to cut the signals adequately....there are guys at this site that can advise you on more inexpensive powered subs that will do a most adequate job for you that will please you ascribing to what you have described to us as your desires....do you fellow Audioholics agree?....Willhub, happy listening and good luck.....

.....aaahh, I missed this one, Dannv....so you have a like system, huh?....sounds sorta' like the same setup as a Bose cube and sub system....there it is, Willhub....youse need a receiver first of all....forget the inexpensive sub proposals, Guys, Will has to start from square one it appears....whew, I'm about typed-out, and have a headache from having to think too much, haha.....

Ok, so i need an reciver first? not an amp? or are they same things?, is there any amps that will do a good job of powering 2 subs at abouy 400W rms or even up to 700W rms that cost around 100 pounds?

I am still confused, all this audio stuff is so much more confusing that i thought.

If i can find a guide on making a box for the particular sub's i want to get, then i can make a box good enough and it will be cheaper than buying one, so i need, Amp, 2 of those Infinity subs or even 1? and a reciver, i could use my logitech z5500 speakers, all i need to do i would of thought is plug a cable from the subs into the back of my X-FI Fatal1ty into the port thats for center/Subwoofer then i should be good to go?

I was looking at Realm of Excursion at 12" infinity perfect subs, and they dint seem that loud, of course they were louder than my z5500 lol, but the dint seem much louder than this and my z5500 sub wasent even fully maxxed out:http://www.youtube.com/watch?v=JC68MF4cS0o

I suppose one powerfull sub thats capable of going loud will do for now for about 150 quid, i only really want a sub that can go really really loud with bass, my Z5500 is good enough for movies, just not when i want to play music with tons and tons of bass, of course i dont want to get an extreamly crappy crappy sub though, i havent heard a really high quality sub before, so i dont suppose even with a tottally crap sub i would think the sound quality was crap, but still would like a sub thats not tottally crap, also people say my z5500 is made for explosions, maybe thats so, and the z5500's bass quality aint good, its still good bass, just dont go loud enough :(

(sheep am not trying to go off topic, just comparing my z5500, and what does troll mean, i thought a troll was some wierd thing :s)

.....Will, a receiver is comprised of three sections....a tuner/radio, a pre-amp section, and at least two amp sections in a stereo receiver, and 5 or 7 amp sections in a surround receiver....an amp is comprised of one, or two, or five, or seven amplifier sections, that needs a seperate pre-amp to be able to perform, and a seperate tuner/radio for radio.....

.....not sure what a pound/English is comparable to the dollar/US, but I would say yes, since you don't HAVE to have as many watts available as the sub is rated to take.....

.....yes, that's true, but I would still advise you to go with two inexpensive powered subs produced for home usage.....so, let's review....I think you need a decent receiver with LFE output you can Y to two subs, two inexpensive powered subs, and at least two full-range speakers to begin with, with more to come to compliment a 5.1 receiver.....

whats a PreAmp? so i need 2 amps and a preamp?, i just want more bass, there must be some way to use my Logitech Z5500's for the main sound and the 1 or 2 subs for the bass, surely just plugging it into the sub/center port on my X-FI should work?, i just want subs, no speakers really.

.....not sure what a pound/English is comparable to the dollar/US, but I would say yes, since you don't HAVE to have as many watts available as the sub is rated to take.....
if i dont have as many watts available on the amp as the sub is rated at, so say 400W rms amp and 700W RMS sub, that means the sub wont work to its full potential right?

but I would still advise you to go with two inexpensive powered subs produced for home usage.....so, let's review....I think you need a decent receiver with LFE output you can Y to two subs, two inexpensive powered subs, and at least two full-range speakers to begin with, with more to come to compliment a 5.1 receiver.....
Y to 2 subs? so 1 amp to 2 subs?, an Amp like that will cost lots right?, my z5500 speakers are good enough, i want to use the Z5500 and 1 or 2 Subs at once, as the Z5500 speakers go loud enough, its just the sub, so cant z5500 + sub/s be linked to the computer?

Also, how will i connect them to the power in the house, coz they will be car amps right?.

So what subs should i be looking at?.

Here are some translations:
150quid = 283.709$ (Price i would like to spend max on 1 sub)
100quid = 189.139$ (Price i would like to spend max on a amp)

Power handling does not dictate output of sound.

Just because a sub handles oodles of power, does not mean it will have great performance or output.

A majority of subs for the car simply will not do a good job in the house. However, there are some that will excel. JL audio has great drivers that would be at home in the car or in... well... the home.:)

Adire Audio has some great woofers for the home as does Dayton on the DIY fronts.
