The Official Type R Thread

[Spkrman]

Maybe there was other issues involved in the decommission of the sub. And, as far as i know/have heard, all david did was swap out the seXXX's for SX's in his old car (wall with 2 15's and 2 or 4 35.1's) and got numbers.

as i remember it too

If all RE did was have one of their people swap out subs in his car, then decided to scrap the SeXXX (along with the HC), I would be very disappointed in their testing department. hehe

wang... time to be disappointed.

Why are we even assuming that the reason RE scrapped the seXXX line is because of SPL numbers? There could be many other variables.

Anyways, I think Alpine is underrated as a company. They always make solid gear, and even if RE is the best small speaker manufacturer out there... Alpine just has an R&D dept thats tough to beat.

notice he said MY car.....

And he also has less power than me, and 15's //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

da useless eh?

You expect the 10's and 15's to have such a great and opposite efficiency, eventhough they use the same motors (sx 10 to 15 and SeXXX 10 to 15 respectively)? Okay, Im glad you are willing to make that assumption, Im not. I see no reason why the cone size ould affect both subs in opposite manners. Do you? Do tell.

I think it has to do with moving mass and power handling. The mass of a 12/15" is greater than that of a 10", thus it won't take as much power to move the 10" as it would a 12/15".

That's one of our guesses.

But like i said NUMEROUS times, i really have no explanation for MY results. But go ahead and look at my teammates results with the 15". SX vs. type-r, type-r did the same score, at a lower note too i believe, and still has some more in it for sure.

Same phenomena, different sub. There goes your "stance" on the 15's and 10's acting differently. They are doing the exact same thing in our setups.

Was this test done with the car sealed up?

As the results show, no. The door was open, MECA legal style.

And trust me, my truck has become very consistent over the years, and the most consistent way is with the door open. My truck HATES being sealed up.

Sorry tommy, but that explanation doesn't make sense. Obviously the moving mass on a 10 is less than a 15, but we were comparing 10's to 10's, and 15's to 15's.. not 10's to 15's. The RE tests was all with 15's, showed the SX was more efficient (at least in that test). When we switch to 10's in your test, the results come back just the opposite. The change in moving mass affecting efficiency could not be the culprit here since both subs in your test (SX and SeXXX) are 10's.

Actually, i was referring to my buddies 15" test as well. He has a single 15" setup in his blazer, and he got the exact opposite results that david got as well. Although he did not switch from an seXXX to an SX, rather an SX to a type-r. The SX fared no better in his setup either.

David's test holds no proof against our results. Why are you so adament about using his tests as the bar to which all other RE tests need to be held to?

Ah I see.

Ah I see.

Sorry, edited my above post. But you can see where i am coming from.

 

[audioholic 5,000+ posts]

Yep I see. But I do know Ive seen the RE guys refer to this test as showing the efficiency differences between their drivers (they referred to it for showing the MT is actually a very efficient driver, thier most efficient, contrary to popular belief). Lloyd (bigbassman) has confirmed this to be true. I still find it hard to believe this is the only test RE did before discontinuing 2 models of subs. I suspect they did alot more testing that was not published. They designed the subs themselves, Im sure they know what the efficiency differences are.

Its all just... weird. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

As i have come to find out, everything with my truck (SPL wise) is weird...

Lower note=higher SPL

me getting out of the car=.7 dB increase in my reality score

Box design that makes NO sense for my kind of setup=best scores to date

open glove box= SPL LOSS

As you can see, my truck is VERY weird. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Thus why these are MY test results and may not be applicable to other vehicles //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif /disclaimer

Is it a first or second gen S-10? Some of those really are some weird results. lol
