New member Username: BiochiPost Number: 1 Registered: Apr-05 | Hi: New member who knows nothing with a question: I have (4 each) 4 OHM (25Watt) Shakers that I am installing in a massage table for a research project involving tactile low frequency impulses. My PA is 125 watts per channel (250 total) or 350 watts bridged at 8 ohms and its speaker impedence is from 8 to 16 ohms for channels A + B or bridged. So there appears to be plenty of power for any possible circuit. All shakers will output the same program. My question is what wiring schematic would optimize the shakers output. 4 individual (left and right on channels A and B), all 4 in series bridged, just channel A with 2 in series on left and and 2 in series on right, or 2 in series on channel A right and 2 in series on channel B right? Thanks in advance for your help. Ted |

Gold Member Username: SubfanaticWalton, Ky Post Number: 2053 Registered: Dec-04 | ok the eclipse right there is a decent sub, it is the eclipse al, BUT its the 7000 series, not the 88000 series, if your giong to look into eclipse AL's go with the 88100 seriers, good spl, but the most amazing Sq of any sub i have ever heard/owned, it is better than the jlw6v2 even, its amazing, its only 30 bucks more on that site, its amazing, but if your going to seriously look into eclipse, look into the Ti line, i have a 15 inch Eclipse TI, and it has the sq close to that of an al and the spl of a w7(actually more its far superior) and it is by far the best sub i have ever heard. so if your looking into spending a grand or two, do this im going to do a 2 grand AMAZING SPL AND SQ setup, get 2 15 inch or 12 inch ECLIPSE TI's, on that site they are 500 bucks, but go to electronicgiants.com and i got mine for 350 lpus shipping, so thats like 750 bucks there, and now you have 1300 on other thingts, you NEED a HO alt, so figure that at 300 bucks(motor city remman.com i would suggest a 200-300 amp alt), so thats 1000 bucks to work with an amp and box uh you need an amp that is 1 ohm stable and puts out somewhere between 1500-2000 watts rms at 1 ohm so i would suggest an old PPI art series amp or an Orion amp if you can find them at decent prices, remember your looking for an amp that puts out 1500-2000 watts rms at 1 ohm times 1 or 750-1000 watts rms times 2 at 2 ohms. or you can find 2 mono amps and this is what i suggest, i suggest getting 2 ednine.1 (edesigns.com) and run them at 2 ohms and get 900 watts rms to each sub, OR get 2 jbl1200.1 and run them off those but make sure the boxes are ported. so if you order the 2 ednine.1's ibelieve they are 350 shipped then you have about 400 to work with a box. i would suggest having someone custom build you a box tuned around 25-35 hrtz ported, or if you want spl, i would go with 5 hrtz below your cars top frequency to kill yourself lol. But def go ported and get them custom made, OR get two ss boxes, www.powered4sound.com but this will run you over 400 sorry lol. and dont forget plenty of sound deadener, since you will get the ednine.1 get edeadv1 120 square feet off ebay for 100 bucks plus shipping, not bad, and if you need a HU go with clarion, eclipse, alpine, pioneer premier. lol, but this is all off the top of my head |
