4 18 in BTL or MT's

[Liquid Bass 10+ year member]

ok i want to know which of these subs would be louder and still sound ok?.....but my friend wants to buy a 12 in. type R and i told him he should buy my mj-18. he wants loud but it to still sound good...so which one would be better for SQL, the mj-18 or the 12 in. type R?

your topic is asking about 4 18" BTL's or MT's and your asking us type r or MJ-18. im confused?

no i want to know which ones would be louder the BTL's or the MT's....but at the same time im asking about the type R and the mj-18, sorry for not making that more clear

well. um. i dont know which would be louder. you would have to have 2 people with the same vehicle, same box, same power, same electircal, same everything to be able to find out. i personally would go for the BTL's. theyre cheaper. they are not CHEAP, just CHEAPER than the MT's. and as far as the type R, if he wants it, let him get what he wants. not what you think is the best for him. because obviously you dont know what would be better, because your asking us the same gerneral question hes asking you.

i wasnt telling him it would be better i told him i would ask what you guys think.....?

i think [Ngsm 13] is a wast of life

I dont think that means much coming from u.

How about one person? I'll know tomorrow. . . .

I am switching from MT's to BTL's for the longer coil and the full cooling option (which is now patent-pending "heli-cool"), since I wanted the loudest possible system for music.

Been a few days, but here is what I think:

They sound pretty much the same, but the BTL's are a little stronger down low. I like the fact that they still kick up in the higher bass frequencies like the MT's do.

Now I know there will be haters on this (I had countless PM's stating I was making a mistake going from MT's to BTL's), but on the meter, the MT's were louder (by 1 dB on a burp, and 0.7 dB playing music), but I was running each MT on a strapped pair of MD3D's at 1 ohm (before impedance rise), so they should have been doing around 4000 watts even after impedance rise. I am running each BTL on a IA 40.1 at 1 ohm (before impedance rise), so with rise, I doubt I am getting 4000 watts to each BTL. In the next couple of weeks I will rewire the 40.1's so they are strapped at 0.5 to see what kind of numbers I get. I will post results when I get around to trying it. The way my amps are mounted, changing speaker wires around is a pain. I think I am going to build a speaker wire connection plate to make it easy to change tham when I want to burp.

For music (to the ear), the BTLs sound louder due to the increased lower frequency output. The three people who ride the most in my vehicle all commented that the low frequency was noticably louder without me saying anything to them about the meter results.

And the best part (the main reason I made the switch), amps and subs will pound out music for long periods of time without straining anything. . . .MT's after 30 seconds were hot and had the funny smell to them. The BTLs play at 154-155 dB for long periods of time without any problem. I ran them hard on and off all day Saturday at a show in Frisco (85 degrees outside), and the dustcaps felt warm every now and then, but never really hot like the MT's would get. Of course I have already stated I am running less power to the BTL's, so that is part of it, but to lose less than 1 dB playing music and be able to do it all day long instead of for 30 seconds is worth it to me.

I will also note on the loudness - Scott told me straight up that the BTL's would not meter as loud built with the full cooling and daily options due to the increased air gap and metal machined out of the pole for the cooling channels. . .

If you have ever sat in a car playing music with bass centered from 36 to 40 Hz at 155 dB, you know I still have more than enough output for a daily driver. . . //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Nice review man. So no going back to RE huh?

 

[Brian Owens 10+ year member]

No. . .I will stick with the BTLs.

I would trust Fi's customer service over RE's anyway...

 

[NDMstang65 10+ year member]

Glad ya like them Brian

BTLs it seems is the way.

 

[PSturmer 10+ year member]

i think the btl fad is over by now....

the hdc3 fad is soon to start, so you might wanna get ahead of the game and just get some of them
