SoundSplinter

Slumpin - box spec's will be publicized this coming week, for now I'll just say that these are not geared for a small box environment. I hope you understand that I am not comfortable addressing this question conclusively, as sound quality is extremely subjective and what one's ears may love, another's may not. That said, the Supreme drivers will sound different than the RL-p's, and while the Premium series drivers offer very low distortion bass reproduction, distortion on the Supreme series is nearly non-existant. Qualitatively, it is in the ear of the beholder to decide which sound they prefer. I wouldn't hesitate to use either!.. but if you're a fanatic and want the best of the best, the Supreme series is your ticket. cougarballa2k5: Though I haven't lined these up on a mic side-by-side, given the nearly 60% increase in displacement between the RL-p and RL-s series, I would be inclined to believe that the Supremes will get considerably louder.

3.2 cubes per 15" is on the small side for the Supreme series. Unlike the rest of the SoundSplinter lineup, the supreme drivers excel in larger enclosures. They are meant to be extreme, but not necessarily practical! Comprehensive enclosure recommendations will be released this coming week.

Seems you're already running around 1.2 cu ft net per driver sealed - I wouldn't really recommend going any higher personally. If you're lookin' for more output or just want to mix it up, going ported with one or two drivers would be cool. I'm sure a single ported RL-p12 in an Integra would be more than enough for most people.

That doesn't sound too bad, but the first run's done - so I'm not making any promises at this point!

Hey now what you got against the cone? Personally, I would've preferred to keep the theme of the black annodized cones EXCEPT that they didn't offer as strong of a connection at the voicecoil former. This off-white aluminum cone is really beefy in comparison, and on a driver like this, it's definitely a tradeoff I'm willing to take!

After a year of negociations and a few months of pedal to the metal design and fabrication - the long awaited Linear Motor Technology from TC Sounds has be- come a production reality! I am very pleased to announce that SoundSplinter is the first public distributor to carry this exciting new technology, and that these drivers are impressive to say the least! Featuring a massive custom-tooled linear voicecoil, these drivers come at you with an RMS rating of 1000 watts, and should comfortably handle 2000 watts in skilled hands. This driver is designed for the most extreme and discerning of audio enthusiasts. If you don't have at least 800 watts to play with, consider our Premium Series drivers which perform very capably with 400-800 watts! With a sturdy tall rubber surround, rigid aluminum cone, super strong epoxy glues, quad-stacked ceramic magnets, thick gap-plates, spring-action terminals, and beautiful powder-coated high excursion basket, this driver is nearly bullet proof. On top of all this, we have taken the time to perform custom in-house machining on our motor's T-yolk in order to accomodate high quality copper shorting rings in all Supreme series drivers. This process aids in reducing flux modulation, making for even less distortion on a driver that is already as clean as it gets. TC's Linear Motor Technology involves a revolutionary new voicecoil which allows the driver to maintain a constant BL product (force) even at the extreme high and low ends of its excursion capability. This innovative and unconventional driver design will require us to let go of some generalizations that we draw from various Thiele-Small parameters. Consider the Qts of a conventional driver; While it may be around 4.0 in a free-air parameter test, once inside a box and moving, it will likely raise to around 8.0 during full excursion. Linear Motor Technology allows the driver to maintain a constant Qts and BL value, so while the BL parameter may be lower and the Qts may be higher than in a traditional driver, we need to remember that we are working with a whole new beast and cannot take these variances at face value. Which, once you plug one of these bad boys in, I'm sure won't be a problem! Put it all together with dual spider suspension incorporating woven lead-wires to eliminate any possibility of tinsel-lead slap, a killer coil rated for 3.5 Ohm operation, precision-machined parts, along with the expertise of the industry leaders at TC Sounds, and you have a rock solid driver capable of true 3" peak-to-peak excursion, with a one-way Xmax of just over 38mm ! More information including T/S Parameters, enclosure recommendations, and list prices will be made available, right here on SoundSolutionsAudio, within the coming week. Anxious to get your hands on one? Contact us for ordering availability. Waitlist members will be notified tomorrow and be allowed a one-week head start

I will not! I just think he's slow

D'oh - 400 watts will hardly get her moving. To get this driver happy, you're looking at a minimum requirement of 800 watts per driver, preferably around 1000-1500. ...Now go buy another amp!

IshbOO, keep us posted on your problem - hopefully it is something as simple as a leak in your box or the driver hitting some loose material in your listening space. Funny story: I had a customer ship back a driver that he thought was defective a few months ago, but it turned out that there was just a loose piece of carpet that it was flapping against at high excursions. Upon testing his returned driver it seemed fine, but I had already sent out the replacement so I wrote it off as over with. Then when the guy told me his other driver was giving him the same problem, I had to ask him some more detailed questions and he eventually found the real source of the problem was just some interferance from outside material But hey, I want to make sure your equipment is working well, so please closely inspect your driver and get back to me so we can get ya patched up under warranty as soon as possible if there is a problem with the driver.

That you there Dave? If it is, I'm sorry about that mixup with FedEx ..they still haven't picked up the package, 26 days later I figure I'll file an insurance claim next week and either get some cash or the driver back

I will be opening a new thread on this topic over the weekend and will have the spec's released by the beginning of this coming week. Shipping will commence in no more than one week. Demo-ringers will be receiving email this weekend as well

Yes - that box indeed looks pretty sweet - but 40 Hz? Personally, I couldn't stand that high of a tuning frequency

I'm glad to hear someone commenting about this. There has been a fair amount of guff in the wake of 1s4pimp's experience with his small sealed box (granted his was considerably smaller, coming in at around 0.83 cu ft net if memory serves).. but I agree that the slightly smaller boxes around 1.0 - 1.15 cu ft net volume are very nice. Then again, it all comes down to what each of us likes personally, as well as how well things will meld with the rest of our stereo gear. It seems that on the whole, people still prefer the added output of the 1.25 - 1.35 cu ft net enclosures. Of course, this added output can result in a slight peak or "boominess" at certain frequencies - where smaller boxes around 1 cu ft net will offer a flatter response at the expense of a slightly muted extreme low-end. It's always a give and take - which is why everyone should play around with different enclosures before giving up on ANY woofer (even a funky pup lol )

Well, you will get a very flat frequency response using such a small enclosure - however the roll-off on the low-end will be terrible and aren't subwoofers all about the low end? In short, I wouldn't recommend doing what this guy is saying...

They're here... .. and while I might sound like a doufus for saying this since everyone would expect me to, being the owner and all.. damned if I can't help but tell you that these drivers are something incredibly special and very unique. If you thought our Ignition and Premium drivers modeled strange, wait 'til you take a peak at the T/S param's on these bad boys - truth be told, the Praxis software we were using to pull the thiele-small's couldn't even get a proper read on the 12" version since the software had trouble fitting the impedance curve of such a non-conventional linear voicecoil driver. In effect, one might consider this is a revolution It's edging close to 4 in the morn' though (literally just got back from TC Sounds with a small but respectable load of Supreme 15's!), so I don't think I'm going to delve too deep right now. However, if you have reserved your claim for our demo-ring, you will be hearing from me shortly - and you can certainly expect masses more information to be released within the coming week! Teaser

Looks pretty good to me. I'm getting 2.733 cu ft after displacements, making for a 4" round port that would be 12.88 inches long to achieve the tuning frequency of 28 Hz.

I think Kent's (mrray's) suggestions were made with the RL-p12 in mind. With your limited space, I would definitely recommend stickin' with the sealed box, as close to 2 cu ft net volume as possible.

Welcome to the best audio forum on the 'net.. maybe not the busiest - but there are some damn fine people here to be sure! So far as an amplifier is concerned - anything that is going to feed an RL-p between 500-800 watts at 2ohms would be perfect. eD's Nine.1 has been a popular candidate, and HiFonics & Orion offer good value as well. I believe our brother forum Zed Audio's lineup includes a suitable 600 watt amplifier too! Check out Used Car Audio classifieds, eBay, and all that jazz... For hard-hitting and space-saving bass with an RL-p12, I would suggest a 1.4 cu ft gross internal volume sealed enclosure. You might also find that you like anywhere from 1.5 - 2.2 lbs of polyfill inside the enclosure to help boost your output. If you want someone to look over your plans, keep posting!

Hrmm.. your box seems to be around 2.8 cu ft net volume. I like to keep my RL-p15's in sealed enclosures between 1.75 - 2.25 cu ft net volume. If you're really craving more output over the low-frequencies, perhaps you indeed should go with a ported box. With about 5 cubic feet to work with, you should be able to squeeze a 2.5 cu ft net internal volume tuned to 28 Hz in there.. and I say go for it!

Candy ass?!!! Don't be talkin' about my Norah that way!! She is awesome, and of course - to each their own!

Right on Haydenlake, though for the low-end monster box on the 15, I would suggest a slightly more practical 3.5 cu ft net internal volume @ 24-25 Hz (the 5 cu ft would be too peaky in my opinion)... and of course I will reiterate that for in-car use I think this size and tuning is unecssary and would aim for around 2.85 - 3.0 cu ft net @ 28-32 Hz tuning, but for home theater the larger lower box would be bangin' (3.5 @ 25 on a RL-p15 is what I'm currently using in my own home theater )! Definitely fill us in a bit more as to what your main concerns are at the moment aside from the aesthetic flush mounting for your trunk. Also would like to know more details on your current enclosure.

If you don't mind learning, then you have nothing to be embarrassed about! To begin, this link from the good (and money hungry ) folks over at JL Audio will exaplin all you need to know about the ported enclosure alignment JL Audio's Ported Enclosure Tutorial Another great link: Basic Car Audio Electronics Guide to Building Subwoofer Enclosures Once you understand the basics, I would advocate using an online calculator to simplify the process: Easy to Use Calculator for Round/Square Ports

Kent's got the idea. 2.1 cu ft net volume sealed (2.31 cu ft gross internal volume) is my preferred sealed box rec on an RL-p15 for a beautifully even frequency response. Indeed, ported RL-p15's should have at least 35 square inches of port area per driver, and for in-car use I would tune between 28-34 Hz. Lower tuning in-car is unecessary in my opinion since cabin gain will boost the low-end naturally and the lower tuning will ultimately take away from the output over the higher sub-bass frequencies that are more commonly exhibited in music samples.

We are moving into production as we speak! Should be but 1-2 weeks providing everything goes smoothly from here

Looks like a solid box.. 1.42 cu ft on the RL-p12 is fine Aim for power in the range of 450-850 watts
