DBX vs. RL-p **PICS**

[jellyfish420 10+ year member]

i traded my $500 gift certificate for these 2 db extreme soundstreams. they seem to be a little bit beefier than the RL-p's they are ran to a .5 ohm final load. my amp seems to be doing ok, w/ impedance rise i expect it to be around 1ohm. i'll graph it later to make sure. the basket is about 1/8-1/4" bigger on the dbx's. well here's the pics.....

which one is louder?

Sound comparison?

god i hate tilted subs.

god i hate tilted subs.

its the only way they will fit...the angle on the port hits the frame if i don't.

the dbx's are louder! i've only listened to them for about, maybe 5 minutes...i wanna graph my impedance before i go cranking it up real loud. i'd hate to blow my amp on account of doing something dumb //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

probably later tonite i'll have had a chance to listen to them and i'll let you guys know.

here is some quick ****. i'll get some better up later.....

here is the impedance graph between the rl-p and the dbx.

you think my 1 ohm stable amp will be ok dipping to .75 on occasion?

reason they are louder is your gettin more power from the amp.......a good bit more. put em on the same power the RL-p's got and see what happens.

they still get louder the first day i didn't even turn it up half way(i wanted to see how the amp would do @ .5ohm) and they were still louder.

the question i got is how come the dbx's w/ 14mm xmax seem to move a hel of alot more than the RL-p's w/ 24mm. and how can the xmax's be that differenet? these are both TC9 motor subs.

do the soundstreams SOUND good or are they just loud, i see they are reccomended to be tuned at 45

P2P versus one way?

those soundstream subs definatly have more xmax than 14mm

one way vs one way //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

maybe measured a diff way? that is the one thing that never made sence about my RL-p's...i have had 4 diff TC9 subs.HCCA 15mm, HYBRID ~17, DBX 14mm, & RL-p 24......

you guys obviouesly dont understand xmax........

im sure the dbx's move more, but not linearly.

xmax isnt an indicator of how loud a sub will get.

 

[chubby 10+ year member]

also, .look at the sensitivity. the dbx is much higher (99.9 ?), and the dbx has a higher power handling.
