Would I Get Better SQ......?

[Arawak420 10+ year member]

with 2x 10" type r in a ported enclosure,

or 2x 12" in a sealed enclosure?

there is only a $25 difference in price between the two.

I'd go with 2 x 10" type-R's in a SEALED enclosure //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif ported is not really for SQ.

are the 12"s in a sealed enclosure not for SQ.... would it still be loud as hell? i listen to reggae music strictly and want the bass tight and not long and dragged out. although i do listen to some hip-hop, funk/jazz.

2 12s sealed.

oh boy more Type R threads,

 

personally I would seal them

Get the 12's sealed. If you want any form of SQ from your bass, sealed is a good place to start. Also choosing the 12's over the 10's will allow you more output and low end extension.

Remeber driver size has ZERO to do with SQ. When comparing the same models

I know what your saying and agree for the most part..but different driver sizes usually have different frequency ranges, and when comparing an 18" to a 10" for example, you are most likely going to be able to have better low end from the 18", while it might not play as accurate in the 80-100Hz range, like the 10" would.

Though again, I do agree, you won't see much difference between going with 10"s or 12"s of the same model.

Yes an 18 will have a lower extension on lower frequencys, it is the nature of the driver. But this will have zero bearing on the SQ of the driver. They will both play the music just as accuratly as each other. And I never understood why any one would expect to play anything above 80-90hz...

But I guess not everyone has a decent middbass setup?

I believe he was speaking in terms of transient response of the speaker, not frequency response. But I certainly agree with you. Alot of people want to place complex situations into simple guidelines. Use to be one of those guidelines was 'larger cone speakers are slower'. Now its 'cone size does not affect SQ'. Meanwhile, as you alluded to, there more to the situation than either one-liner suggests.

Frequency response of your sub and over all subwoofer system should be tailored to match the rest of your system. If your front stage consists of 4x6's, you wont likely belnd real well with an 18" 'supersub'. Conversely, if your front stage contains 8" dedicated midbass drivers, you probably wont see alot of extra low-end extension going with mild 8" subwoofers. SQ isn't just about THD output or transient response, its about blending your system to work together.

How often do we see someone asking which type/size/quantity of sub to buy, and have people swarm to give their opinions, all the while he has not once mentioned his front stage, nor does anyone usually bother asking.

I do agree with you and completely understand what your saying.. I was just stating an example thats a little more on the extreme side (as most people choose between 10" or 12", or 12" and 15"...not 10" or 18"). And there are alot of people out there that do lack in the upper sub/midbass frequenices (70-100Hz), where a 10" sub could be allowed to be crossed over a little higher, and make up for the lack of punch from the mids. A 10" of the same brand/model will typically play into those ranges more accurately than a larger 18" driver.

Again, not saying that a drivers size has any bearing on its SQ, just that a different size driver can play better/more accurate at certain freqencies...hence why we use 8"-18" subs, ~6.5" for midbass, etc. So, it may make a difference in the overall SQ of a system, should that system be lacking in a certain area.

SQ is more than just 'accuracy'. Your comment was driver size has zero to do with SQ. That's not quite correct, as I said above with the blending issues. Its true it has little or nothing to do with transient response on any decent driver (or at least an inaudible difference as compared to changing enclosure alignments, a much bigger factor), but chosing the right driver size/quantity has everything to do with 'SQ' when chosing the right one(s) for your system. We know what you meant, but lets not go off the deep end here and state cone size has nothing to do with SQ. That's too broad a statement to be correct.

Understand where you are coming from now

A subwoofer system should never be lowpassed any higher than 120hz or so (imo even that's way too high). At that frequency, you'd have to have some incredible ears to hear an audible difference between a 10 and an 18 in terms of transient response. Chosing the proper sub size for your system should be based off of desired output, desired frequency response, and available space if its a limiting factor. The cone size should not be determined by some notion of transient response (low end or high end).

Yeah. I agree. I was just giving random frequencies (70-100Hz) as an example. I would not suggest crossing over much above 90 myself, even with a "super woofer". Even most decenty designed coaxials, can accurately play, and give a nice "punch" in the 90-100Hz range.

A coax would be hard pressed to keep up with a superwoofer however, and blend properly. You would end up attenuating your supwerwoofer's output, or have overpowering bass (what most people seem to do). I don't recommend people go with a XXX, Brahma etc unless they have a substantial midbass setup (more than coaxes). And yes, 90hz is about my upper limit for subs also (I prefer 60-70hz when possible), but I know alot of people like to go as high as 100-120hz depending on their system, so I used that number. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
