Audio Pulse Lms-ultra, Anyone Runnin' Them


Recommended Posts

Ahh yes the good old powerhorns

at low to mid 150s on music a set of components sure does not keep up

so why not stay clear at least?

selenium makes a nice set of horns I am putting together for my other build.

Right now I am doing the same numbers as the LMS ultras (154s uncharged) off half the equipment with tc5200s for a few reasons

I stepped up port area as well as tuning

shrunk the box slightly and dropped the hieght as well for better airflow

also to accomidate for reactive load being somewhat high in the old box

obviously the lows don't murder the car anymore which is nice but the 40-50hz range is extremely painful to the ear.

The SQ aspects of the vehicle are gone with these woofers but I don't care becuase setting the car up for the mic instead of daily was a nice change.

putting two tc3000 12s in right now

...for the 149.9 class

I wouldnt say that completly. After experince with both setups mike i think the 5200's sound just as good as the lms's but just not on the lows due to port area. Both woofers sound great and get hella loud but since the new box does the same number with half the power i think i like the 5200 a little better.....but the lms's deff kill the lows lol

Did you say 49.9 class with 2 12's???????

If you do it you gotta post up vids or something 49.9 on 2 12's is feeskin INSANE think the 12's could hold up to that abuse?

Have you ever had your woofers blown?

Yea shouldnt be too hard in the hatch with the right power and a well designed enclosure. I know the coils will be able to take it no problem

I have yet to see anybody hit a 49.9 with anything less than 15's its gonna be tuned high huh

With those woofers I will not need to step anything above 50-55hz.

Plus I already know the coil is the most efficient on the low side of 50hz (49-51 did the best in the lincoln on them before we pulled a 160)

they are a 3" flatwound versus the 4" on the LMS and the 5200 (5200 is also flatwound and built more fot he mic).

In no way was I suggesting the 5200s sound bad (the output on the response curve bandwidth for the loudest frequency range all comes down to listening preference)

The coil design on the LMS is simply a work of art to me though on the other hand (the design spikes certain frequencies in order to help acheive flat or close to flat response in extremely small boxes)

There is still tons of music thats gets down and dirty on these

When you drive around when daily setups for several years switching over to the SPL side is a nice change

So I was thinking though

in my enclosure thats around 16-17 square inches of port per cubic foot I have not seen a direct comparison between the woofers on the SPL side because of different boxes and wiring. I am interested in finding out if the LMS line will shine in a box as small as what the 5200s are in now.
