Does anyone have a measurement or a link to a measurement of the Alpine 1542D or 1522D in a sealed enclosure? I'm kind of wondering how the top end performance looks.

There are a few places offering it for $200 w/freeship.

It appears to work nicely in 1.5-3.0 cubes sealed, which opens the door for dual opposed without getting too large.

20.5 mm xmax (conservative) and 35 mm before the suspension runs out. 750 watts rms handling.

specs: http://www.alpine.com.au/files/curre.../SWR-1542D.pdf

No inductance ring.

Radial venting/cooling.

Listen. It's All Good.

Don't have a link for you, but there is something to consider. The smaller models underwent a change for this year and incorporate some interesting design features. We can only assume that the 15" Type R will get an upgrade sometime soon. It might be worth the wait.

I asked someone who works at Alpine if this was going to happen. No news yet but will update when I find out. Still, at $200 it is a contender in current form

thanks jp. i am familiar with what you are saying. just kind of curious how the current 15 stacks up, dollar for dollar, against the competition.

"will update when I find out."

cool.

I've heard the current 15" Type R in a "max-flat" sealed box (like we would use in HT rather than a car audio system) and I thought it sounded very good.

Already moving onto the new Type-Rs when the current 1243/1223 has been out for maybe a year. Looks like theyve completely forgotten about their 15"s... a lot of car audio people think 15" dont sound as good as 12"s because they think smaller woofer = "faster"

Its pretty sad

"a lot of car audio people think 15" dont sound as good as 12"s because they think smaller woofer = "faster""

that might not be the worst conclusion given that many car sub manufacturers put the same motor on an entire line. when that is the case, the qe of the small subs will be the smallest and have the least ring.

this may be where that old line of thinking comes from.

as you point out, there is no reason why an 18 should sound any faster or slower than a 10.

definitely true... i think rockford fosgate is still doing that with the punch p1 series?

but most car audio guys probably have never heard a 15", they simply take it as gospel that 15" sound bad and dont really know anything about motor strength

Heres another woofer that shows a lot of promise

http://www.sonicelectronix.com/item_...L-GTO1514.html

offer $120 and it will kick back $125... i dont see anything too problematic with the t/s parameters. Build two 8 cu ft boxes and throw 2 of these into each of them, low shelf it and you should have extension well above reference into the teens.

edit: Uhh, just submitted $120 for the 1514D and got back $121... wtf

Hmmm... these model very well. At $200 a pop, sure would be hard to resist. I had to stop myself from ordering four of them on Amazon just now.

$200! $A699 RRP and $A479 + shipping is the best I've seen with a quick search down here.

What am I??? A piece of meat? Here for your sim'n pleasures!?!?!



Jk

These drivers are pretty different but both good when used properly, I would think. Kept the parameters the same for pure comparison.... plus... I'm tired.

Sigh, so many drivers. so hard to choose. thanks though... i still think cartoys special for the 1243D for $120 is nice because of shorting rings and all that jazz. Plus free shipping, and no tax for californians

Yeah... I'm really trying to not order the 15's right now. Per my own sim's, quad 15's in a sealed enclosure ~210liters is within a decibel of my own models for the sealed cab I'm going to build for my RLp's. Soooo close.

For me four 1243D would be enough in 2 cu ft a piece. Thats what i like about them, can stuff em in real small boxes, and make the baffle pretty thin cuz its just a 12" driver

Omega...where do u see that the 1243 has a shorting ring?

I do agree that these woofers look like a good deal. The 15 would be perfect if it comes out. IMO 20mm of excursion with a 15 is perfect for someone with moderate space available. 4 of these would make most people very happy.

Good point. Only the 8" model, the last to be developed, mentions a shorting ring.

"new one-piece cast aluminum frame with integrated shorting sleeve"

Even the old 15" model mentions a voice coil heat sink with optimized air flow, patent pending. It may have one as well.

Not all shorting rings are created equal though. Its no guarantee.

My memory isn't perfect, but I could swear that an Alpine guy was discussing the new Type R's (except the 15) over at DIYMA and mentioned shorting rings on all the new models.

was just thinking about this again and another possibility could have been that people were trying to put the larger drivers in enclosures that were too small, which would also result in ring.

Yeah, I believe this is the most common in addition that, like you mentioned earlier, that some 15" and 18" models in a line of subwoofers may have a naturally higher Qes/Qts because the motor is carried over from the 10's and 12'. Obviously this isn't always the case and just...depends.

"Instead of new R15s, we designed a new S15. It's still a very high output woofer (15mm one way Xmax and 500W RMS) but this one focuses a lot more on SQ and control with smaller box requirements. They'll be shipping in March btw

Jim "

Hmm, i think the smaller box thing has to do with "15" sound bad cuz we shoved it in a smaller box high qtc" problem :P

I can confirm same as omegaslast that it's a new Type S 15 and no new Type R 15". Makes those $200 sales of the existing Type R 15 seem very attractive as the Type S are top end of the pricing ladder.

With only the type r 15 not revamped yet, I was thinking the same thing. Wait until eventually they redo the type r 15 inch. You would thinkl...... if they did not make any major changes that they would have at least changed the dust cap to black like the rest of the series and gave it that nice looking, less prominent R on the bottom. A year and a half now and still no new type R 15.

A Good amplifier requires a adequate power supply, It does not matter what the amplifier is capable of if the power supply will not provide the power required. Most amplifiers have under rated power supplies. It is up to you to make sure you get the ones that are
least under rated if at all.
