New Type-R shallow sub ( ouch! )

[Alien Mantis]

I was excited about these, until I seen the price.

I'm sure once SonicElectronix gets some, they won't be this expensive.

But still....... OUCH!

We don't have them in stock yet but they are in our system. $299 for 10" and $349 for 12". I'm sure Sonic will be less than that.

betcha they would go nice with a PDX amp...I love my Bazooka, but I might have to give this one a thought. You could nestle it right into the nook behind one of the rear wheels I am betting...

For $350.... you can just buy the KING of all shallow subs:

To me they look almost identical spec wise, same power handling, and for one being 3 inches larger in diameter, the sensitivity is way to close to justify paying the more expensive cost.

For 1/10 the price Parts Express sells a low profile BOSS sub... Not that i'm recommending it, but... I am tempted to open up my box modeling software and see how the cheap sub actually would perform. Usually any sub $50 sub will work decently in a sealed box... and low profile subs usually have a low QTS which is good for small boxes... it might not be a horrible sub for a cheap & small setup.

I wonder if they have a BL curve for that New alpine like they did with the other alpine sub.... an SQ low profile sub would be awesome.

is the sensitivity rated the same way? 1w/1m? cause 2.83v/1m will give different amounts of power depending on ohm load.... ie 4ohm will have half the power as a 2ohm load even when both are given 2.83v... Common trick used in audio to inflate sensitivity ratings by about 3dB.

The problem with MOST shallow subs is they don't move enough air, and they are not LOUD enough.

They all have great SQ in a small sealed box, but they don't hit hard.

Most shallow subs have a short stroke. A 10" sub is small to start with, so a 10" sub with a short stroke just doesn't move enough air for a nice hit.

( which is why that awesome JL shallow sub is a 13" )

The new shallow Type-R subs are supposed to have a long stroke, and fast response time with the right power pushing them.
As a result, they should provide great SQ with a hard hit in a sealed box.
They are also EXPENSIVE.

The only reason my standard 10" Type-R is loud enough, is because it has a fairly long stroke ( 18mm Xmax ) and it is in a large ported box.
( and I am giving it enough power to push it )

I would prefer to run TWO 10" subs in a sealed box, but that would require a larger amplifier, and I would lose ALL my hatch space.
My current setup cost me HALF my hatch space, and I am not really happy about that either, but it's the price I pay to have "some" bass in my music.
Gotta do what ya gotta do.

Wow. I didn't even think to look at the impedance. I know, I'm an idiot, I just accept it.

Actually.. the industry plays everybody like a fool. There is no industry standard... in the past ten years we got CEA for amp ratings.. but thats a voluntary basis thing, so only some manufacturers do CEA... but still... STILL!!!! no standardized speaker spec testing. It's not just the Sensitivity either, the Sd (surface area of the moving parts) isn't standard, obviously the cone counts in the figure, but also the area of part of the surround moves air as well. Some companies figure 1/2 the surround, others do 1/3, and i'm sure some even do 2/3 or 3/4. I personally prefer 1/3 as it is more conservative.

There are even tricks to smoothing out frequency response graphs which make it look like subs play better than what they actually do.

You are correct. Data can be manipulated.

Speaker sensitivity is supposed to be 1w at 1-meter with a 1k test signal.
And of course, that would be okay if you were testing midrange speakers.

A sub does not operate at 1khz.
Usually, the sub LPF is set around 100hz. ( Well below 1k. )

Bottom line is: we look at the product. We look at the specs. We read user reviews. We look for a good deal. We buy it and hope we like it. Sometimes we do, sometimes we return it and try a different one.

It's all a game. Fun to play. Even more fun when we WIN!

I used to own a 12" sub (that weighed almost 40lbs) that could play well up to 12khz... course... it also had a Le of like 1.1mH Which is extremely low for a subwoofer with a power handling of 1600rms and 28mm 1 way linear stroke. It was of course crossed over at 60-80hz tho (depending on what door speaker I was running).

Tone generators are fun things to play with.
