best 18" in 5 subes

[brent338 0]

SO,

after too much measurements, calculations...ect.

I could do a vented enclosure, 1.5" thick mdf all the way around, port it...and after sub disp., still net 5 cubes per sub.

My question now is, what would be best in this "small box 4 sub" type of enclosure...

RL-P, Fi Q, BL,.... would like to get loud but sound good, and these subs fit in that requirement 4 sure... "also need to see 1 ohm at amp(orion 2500D)" side note.

or, maybe 2 DP's? more spl oriented of course.

I was searching threw the SS forum, and someone said 5 cubes would be choking them...?

is this true?, should I go Fi Q/BL w/options...?

or should I stick with a couple 15"s...? as 2-15" properly boxed would probably be better then 2-18"s improperly boxed.

thanks again guys for all the help!!!!

also... why would a dual 4 sub have a higher BL then the same sub in dual 2's? BL is a measurement of motor force right so higher would be better...?

so to say, two dual 4's wired to 1 ohm is > two dual 1's @ 1 ohm..........?

i believe the rl-p would work fine in 5 cubes. but then again, teh only 18 i've ever run said solo x on the cone, lol. and i ran it in just under 5 cubes. worked just fine.

if you are leaning for more output, the 5 cube box should work jsut fine as it'll be peakier then a larger box designed more for flat response. especially with 2500wrms going to the sub.

with 2500wrms, you'll be overpowering the rl-p and possibly even the q. but with proper gain setting and due diligence, you should be fine. the bl would love that setup and reviews have stated it does fine as a DD sub. you might want to lean in that direction.

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Brent, unless you are hell-bent on an 18, I think it would be better in the end to run a 15 instead. In many cases, if a box is too small for the driver, it will roll off high and lack the deepest of bottom end. Would be a shame to do that to an 18. The smallest box 18 sub I have dealt with, (and I have not used many 18's so take it with a grain) is the Mach5 MJ-18. They only come in 4 or 8 SVC. They would play well in 4 cubes each sealed, but are not SPL oriented, which seems to be your goal.

Maybe the best route is a pair of soild 15's that will sound great daily:

Fi Q

Sound Splinter RL-p

SSA Icon

Mach5 IXL

AA Havoc

etc.

Or a single high output 18, such as the FI BTL, and give it plenty of space.

well i meant two 18"...of the 2500.

IF I went 6" over my back seat I could net 11 cubes(if tuned low for 2-18"s), or 10 cubes if tuned higher for say maybe 3-15"s....just and idea.

at level with my seat I get about 7.25 cubes, depending on tunning....which would be perfect for 2-15"s.

and I'm kinda leaning to that route, 2-15"s I think that should be plenty loud... I guess my main goal is to get over 150 DB's on a TL., but still sound good for daily driving.

an SS member said their RL-P drivers are not gonna get any louder after 500 rms, so that is out of the picture... as I'm working with 2500+

So, that leaves Fi; Q's, or BL's... A.A. Havocs, or possibly Incriminator DP's

I'm pretty impressed with the DP's,

very stout looking, great build quality, and puts up some great #'s off of minimal power, but can also take a beating

but, being as new as they are not too many people who run them, so not a lot of feedback...but thats kinda what I'm looking for too....the "who makes that sub?" look...

The havocs only come in dual 2's, so the amp would be seeing a .5 or 2 ohm load... I don't want to run it at 2 for loss of power reasons, and I might be able run it at .5, well after big three, 240A alt, and a optima next to the amp... but I'm not sure how the amp would take it.

Which leaves Fi

best reviews, best support, most wiring options.... ect. but everybody seems to be running them...maybe thats what I should do as well... IDK?

tax return will be on the way shortly, so that will get things moving...

still cant decide....

should just flip a coin I guess.

Hitting 150 is no easy task. Sounding good while doing it is an impossibility. The mids and highs that would be needed to keep up with subs at that level would be unreal.

[brent338 0]

yes no easy task... not too hard though.

bumping at 150, obviously wont be on a regular basis, just to show off and and comps of course....

and most anything below that level; the two sets of MB Quart QSD 216's running on a orion 8004, are plenty loud...their killing/out-staging the subs that I'm running now.

I'll make it happen, one way or another...

[mrray13 30]

whomever said the rl-p won't get any louder at 1250 wrms vs 500 wrms is silly. that said, it doesn't need huge power to move air very nicely. also, one will have to be diligent with 1250wrms on it.

a pair of 15" ICONS would be the shitz. the pair should eat 2500wrms for breakfast (my 12 has eaten 1100wrms for quite awhile), and i don't care what denim or ssaudio say, they get loud! leans towards sq true, but in the right box with the right power, lol.....

and i don't think anyone has been disappointed with their ICON!

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

[brent338 0]

"whomever said the rl-p won't get any louder at 1250 wrms vs 500 wrms is silly."

I e-mailed the company....

I do believe they can handle much more than 500 watts, Imo a close, if not better comparison to the Havoc, just look at the #'s.

Don't get me wrong, the Icons are great subs for the $... but I'm looking for a little more....

cost is no option, I'd pay 2x the icon to get what im looking for...

top choices at the moment are the; Inc. Death Penalty & Havoc.

the Havoc being the best cost option, as well as best looking... while just running 1; 2500d amp....

with the death penalty being just a couple B@d A$$ drivers, that might even give a BTL a run for their money at full tilt, yet sound good off lower power as well. All while having the option of adding another 2500d down the road, if I feel the need.... which I probably will...

I don't know why, but I'm just really liking the DP subs at the moment!

with the havocs a close 2nd, that is if I can get them in dual 1's or 4's.

miek is overly cautius about his products, but for very good reasons.

if the DP's are tickling your liking that much, that's the route to go!

[brent338 0]

probably dp's or havocs.... at the moment, could change you know how that goes....

sent a e-mail to hexibase.com; formerly known as toxic bass, to see what he thinks with the space I have to work with.

lms ultras? just putting something out there

[brent338 0]

yeah if I had 4K to blow on subs.... those would be my #1... LMS ultras are sick....

but 2g's a piece... come on.

the sound splinter Rl-S would be cool, a step down from the ultras... but the only some in single 3 ohm, how the hell are you supposed to wire those....

Positive to positive, negative to negative?

[brent338 0]

funny... jim.

but they require about 2000rms each to full excrusion. the simple fact that my amp does only 2500 @ 1ohm... pretty much takes them outa the picture. could wire in parallel, seeing 1.5 ohms. but the amp would still only get each sub a little more than 1000 each.

And with there low SPL sens. does not help, that coupled with the fact that their also recommended for sealed applications, not vented which is the intended route.

for the rl-s? paper doesn't mean everything. i ran the 12"rl-s in 2.5ft^3@28hz w 32in^2 of port off an orion 2500d @ 4ohm (was the prototype) so roughly 1200wrms...and it pounded. reached low, got loud (single 12, 1200wrms, 4 guage kit, factory gm h/u and it did a 136 or so legal, damn near broke a 140 outlaw and did this numbers in the 35hz range) and sounded beautiful throughout. don't underestimate the rl-s.

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

[brent338 0]

yeah im doing some searching on it.

looks very impressive. arguably the best "LSQ" sub available...

Its very similar to the TC sounds AXIS line, just below the LMS Ultra. except, the SS version has massive quad stack magnets!!! so maybe in between the AXIS & LMS? Is sound splinter still outsourcing to TC?, or have they started making their own now...?

I just wish it can in duals, or something other than 3 ohm. I emailed SS, to see if they can do some kinda custom pair...

but 2, 3ohm...would get 1.5 @ the amp...which should get close to 1200 or so per sub.

should be enough, but I'd like to give'm more...

hell I just might grab another amp if I could get them in custom coils...

thanks, Mmray

for the info about the 12".

Hoffman's Iron Law...make the enclosure larger, needs less power...and what's the "intended" route?

Not every woofer out there is designed for the mobile "groundpounding" boom-car application. For home use, they spec out fine.

Actually, with their Qts the way it is, I'd really like to hear them in an H-frame open baffle...and that would probably take only 500W or so to reach mechanical limits

[brent338 0]

well its doesn't really matter now, cause sound splinter is out of stock of RL-S's and has no intentions of restocking....

They use the technology behind the LMS but on a diffrent motor size.

TC used to sell something similar, the LMS-4000

[brent338 0]

search done....

got two TC-3000 15"s, Q1

identical to axis audio pulse... but with titanium cone...

I was going to suggest AQ HDC's, but you'd need more power. Very curious to see how your TC's do off 2500watts on the TL. Not sure if they have 150's in them, but should sound nice and get loud for a DD.

[brent338 0]

might add another 2500... the audio pulse rec. 2500 watts RMS per driver for the axis line, which is identical to a TC3K...

[chad y 1]

I have a TC3000 15 sealed running off a phoenix gold tantrum 1200.1 I currently have mine sealed and I have to say it is a great choice for SQ. as far as getting loud it does now but I plan on doing a 3ft^3 tuned to 32 hz just to play with.

great choice
