| 169141 | 2003-08-21 04:37:00 | We have 2 Reactor 300W 10" subs on a box that we wanna hook up to the computer . I already have a subwoofer for the computer that I wish to replace (Cambridge Soundworks) but I want BIG!! We hooked 1 of the big subs inplace of my old sub, but the big subs are acting as a speaker playing all frequencies rather than low ones . Could it be that the old sub has a frequency filter in it which tells itself to play only low freqs . where with these new ones it doesnt so it just acts as a speaker? The old sub needs a power supply to run . How can we adapt these new subs to work?!?!!! :) |

| 169142 | 2003-08-21 04:55:00 | your best bet is to obtain a 2nd hand or a new car amp + a grunty transfer to drive the amp :) most of the amp should have a low pass filter to pass only low frequencies to the sub :D Cheers |

| 169143 | 2003-08-21 05:25:00 | You'll need an Amp for your subs, and also a crossover, in order to filter out the high/mid frequencies. You might be able to make use of the crossover in your old sub, and hook the output from that to the amp which drives your 10" subs. | somebody (208) | ||
| 169144 | 2003-08-21 05:29:00 | Can I make one? Can I take it outta my old sub and somehow adapt it?? Im thinking that might work, just splice in the new subs into the circuit of the old sub... Thanks |

| 169146 | 2003-08-21 05:44:00 | You can probably find 300w Amps for subs at the Warehouse, where I assume you got your Reactor subs from. I'm not entirely sure how much they cost, but I wouldn't expect them to be too cheap. Remember, you'll need a multi-channel amp in order to power both subs. You could try getting the crossover circuitry out of your old sub. It will be somewhere between where you plug it into the rest of your speakers/soundcard, and the Amp. I would strongly you enlist the help of a friend or someone who knows a bit of electronics, or is experienced in the audio business to help. If you don't do it properly, you could end up stuffing up your old sub for good, and also risk damaging your new Amp/subs. It might be worth asking to see if the Amp you intend to buy comes with a crossover or high/low pass filter. That way it will save you ripping your old sub to bits. Store bought crossovers shouldn't cost too much - I would expect a kitset one from DSE or similar places to cost approx $50 |

| 169147 | 2003-08-21 05:55:00 | Should only cost you about $300 for a power supply from 230V mains to 12V @ 25Amps. or you could just run jumper leads from your car parked just outside. Maybe the car sub idea can be costly? | Pheonix (280) | ||
| 169148 | 2003-08-21 06:07:00 | My sub I have on my computer right now runs off a *mains* supply, so couldnt replacing the old sub with the new sub using the old sub circuit work?? | Polk (1135) | ||

| 169150 | 2003-08-21 06:16:00 | You would definetely have to invest in a new amp | somebody (208) | ||
