Posted February 18, 200817 yr Hey everyone,So i recently sold my 2 audiobahn 12'' sub woofers, and my amplifier. I have the money now to buy my 15''BTL fully loaded. I had a few questions that i am still not sure about.1.What should my "ohms" be if im using a mono amplifier. 2.If my box is tuned to 3.25feet at 30HZ is that too little feet, and too low HZ?3. Does anyone know a good mono amp to go with 1 fi BTL 15inch4. Also is a BTL legit 2000RMS? i really aprciate all help, thanks everyone. Edited February 18, 200817 yr by shea
February 18, 200817 yr 1.What should my "ohms" be if im using a mono amplifier. Depends on what amp you have, although to get the kind of power you'll need for the BTL you'll probably end up with an impedance between a half and 2 ohms...2.If my box is tuned to 3.25feet at 30HZ is that too little feet, and too low HZ?On the low end of the recommendations, but they do recommend 3-5cF...3. Does anyone know a good mono amp to go with 1 fi BTL 15inchDepends on your budget...4. Also is a BTL legit 2000RMS?It'll take that power, yes.
February 18, 200817 yr 1.What should my "ohms" be if im using a mono amplifier. Depends onthe amp. More than likely a dual 2 ohm sub for a 1 ohm load.2.If my box is tuned to 3.25feet at 30HZ is that too little feet, and too low HZ?That size/tuning will work great. I personally would tune it at 32-35 Hz for a little extra output. It will still have plenty of low end.3. Does anyone know a good mono amp to go with 1 fi BTL 15inchThere are too many to list. What is your budget?4. Also is a BTL legit 2000RMS? Yes it is.
February 18, 200817 yr Ha! Jim and I answered at the same time and got the same answers. Must be right
February 18, 200817 yr Author haha thanks guys,im looking to spend honestly no more then $300. you guys answered all my questions great except i still dont think i know what these "ohms" are. can anyone explainThanks alot
February 18, 200817 yr An ohm is a measurement of resistance.Each coil on the BTL is a 2 ohm coil (what you should get). An amplifier will put out varying degrees of power depending on how much resistance is on it. So if you have a sub that can be wired to 1 ohm (DVC2 coils) your amp may put out more power than say at 2 ohms.
February 18, 200817 yr o chit... what i ment, was... are the dual 2 ohm fis... really 2 ohms a VC...... because the the fi dual 1 ohms,are not 1 ohm each VC.... thay are dual 0.70
February 18, 200817 yr 1 ohm nominal...impedance changes depending on cone position, so you end up with an "average" of 1 ohm for the entire bandwidth.
February 18, 200817 yr Author Ok so it would be in my best interest to get my 15'' BTL with 2ohms instead of one? should i get it universal or no?Thanks for all the help everyone i really appreciate it
February 18, 200817 yr Ok so it would be in my best interest to get my 15'' BTL with 2ohms instead of one? should i get it universal or no?Thanks for all the help everyone i really appreciate itif you plan on getting another sub later down the line yes.
