Wiring at a higher ohm load does reduce the amps output. But you should still be setting your gain with a multimeter either way. I happen to run a smart 3, and at 4 ohms it doesnt make 3000w, it also needs a different output voltage at 2 and 1 ohm to produce the rated 3000w. đź‘Ť

Ahh I seen drill labs on YouTube test one n he got everything thdy claimed but I do remember something with volts though but yeah I usually try not to turn my gains past half which is where it is now n il leave it unless whsn I do wire it back to a 2 ohm final load they sound underpowered but usually my last option I go to I will play with sub sonic crossovers I have an old school even though my radio has a better on I just like playing connect the dots

I could definitely hear 25 hz I had a decaf song that played 40 and 25 hz, and dude, it was sooooo loud. It absolutely murdered my Explorer, that's why I had to have the hatch welded where I broke stuff 3 separate times. I broke stuff bad enough, with 2400 rated watts, I almost lost my entire rear glass, because everything broke that was holding it on, except for one bolt. My Explorer would hit 25 hz. I was doing a mid to high 140's from 25-29. It fell off fairly steeply, but I could hit like a 147 at somewhere between 27-29 hz, and iirc it was a 145 at 25-26 hz, but it fell off really badly iirc at like 23 hz or so.

The song Get Silly, that has the high 20's note in it, I used to mess with people, because most people had no idea there was bass in that song like there was, because few people could really grab that note. I trolled people a little, lol.
Holy shit I remember that was the record when I was last into this and used to have like 4 different mag subs car audio being one of them but I still have the article it was a yellow blazer with 16 15 inch subs and 4 1000 watt Amps lol it hit 147 and held the record prob mid 90s

I have to figure out what hertz my components try ans play once in a while and change it cause it will sound like zhit only like in 2 spots on 2 different songs every other song I've played tgere were no issue but I have 90s Era mb quart q series 3 way its an 8 inch a 5 n quarter a tweeter with the beefiest crossovers I've ever seen come with a component set so how do I figure what hz that is it's some where in the lows but seems like it goes lower with no issues this is like in the middle somewhere if I had to guess

I have heard of people blowing their subs right after they put them in and run full power to them right away
If a loudspeaker is breaking at or below rated power in 5 minutes or 5 years it is either because somebody lied about power handling or there was a problem with manufacturing/materials or there was some other kind of gross abuse or user error happening. There's nothing that happens after (insert number of hours and the magic ritual of your choice here) that is going to be the difference between survival or failure of a sub. Or put another way if you're breaking a woofer, it would have broken under those conditions regardless of what ceremony you performed beforehand.

Once again I'll point out the fact that I'm not saying anything gets louder. The difference in mechanical compliance could surely be measured
I think many break-in believers do claim this, and yes, compliance does change and is (and has been) measured. I offered to share some of my own data on the subject as well as providing several links to data that others have measured but I was attacked saying that doesn't mean anything. Which ironically is more or less true, because the changes in specs (most of which which happen very quickly) do not predict any audible difference over time between new out of the box and the point where they wear out and fail.

Diaphragms are made of a very flexible material. The Yamada diaphragm pumps we use are hilariously durable, because they are ment to be.
As are loudspeaker parts. In fact, I'd wager any well made modern subwoofer used within its limits will out-last the moving parts in a double diaphragm pump.

Sundown Zv2 spider here 8 3/4" version. Seems to suffer no ill effects from folding it in half and feels noticeably softer after just a minute of bending it back and forth in my hands. Since DD came up a lot, they use multiple layers of rather soft and thin spiders.

the spiders or spider packs needed to handle the true 3000w woofers are extremely stiff
Like the Sundown spider in the pic above?

i think we can agree that manufacturers have something to gain by pointing the finger at customers to avoid warranty claims.

I remember reading that Kicker solobarics hit higher scores right out of the box than after being worn in.
Considering this myth is wildly propagated by some ultra expensive snobophile home theater product manufacturers I'd say it's as much as anything just setting the stage for the buyers' expectations when they first get the product installed and start comparing it to whatever they had before or whatever they expect. It's basically saying "hey, don't return this right away if you don't like the sound, just give it a few weeks/months and it'll sound totally different!" Not so much about "breaking in" your new speakers/cables/whatever snake oil they just sold you, but breaking in the listener to get used to the different sound or even just setting the stage of expectation which the user will create for himself via psychoacoustics.

As far as people gaining with fresh subs/recones this would be extremely install dependent and certainly inaudible (under 1dB, and in reality probably only a couple tenths, or in other words the amount of variance you'd likely experience due to changes in the weather, humidity, air pressure, etc.). If anybody could just go ahead and gain a full dB based on the suspension of a new sub those manufacturers would either be designing parts to maintain whatever specs gain so much or be scrambling to keep up with demand for fresh new parts to give competitors the edge.

The song Get Silly, that has the high 20's note in it
And finally posting some of the music with <30hz material in it. Cool. I'll remember that if I ever have the occasion to mess with low tuning.

World record inn 1991 was around 151 and change held by M&M. By 97 Alma Gates had just broken 160 and in 98 her and others were getting into the 170s. Those 90s numbers were old Audiocontrol meters so who knows how accurate those were? That said I think it was around 96 or 97 that the Lanzar van was up in my area with a dozen 15s in a v wall, they claimed 157dB or thereabouts. It was really intense and IMO that build would still turn heads today. Mid 150s out of sealed boxes is nothing to sneeze at.

No you won’t, because you’re just being an asshole and demeaning to everyone really.

You were not attacked; go look at your very first post. You’ve got the biggest fangs here.

I’m a break in knower. A lot of woofers it doesn’t matter, some it does. I’d rather chew on marbles or bang my head into shards of class than deal with your c*nty attitude you immediately take sometimes. It’s like you’re so right that you’re wrong, because nobody is listening to your midol needing attitude.

If you asked for stuff like you weren’t being the absolute biggest prick in the world and a huge know it all, then like we could get somewhere. Your whole attitude has completely ruined this topic.

I know man, I didn’t install hundreds of systems in cars and tune them and make all of these conclusions with my own ears. I think the demons and aliens were in my head tricking me into hearing the bass differently than it was. And like it’s all a lie...it’s the break-in conspiracy.

Who’s trying to trick us into breaking in our subs, sometimes?

I bet it’s the subluminati.....they rule the audio world, some of the best in the business, and they waste our time with break-ins, but only the chosen few realize the truth.

I didn't compare motor oil to spiders that was a seperate discussion. I made the tempering comment as a comparison. Trying to make an apples to apples comparison isn't really possible. Some people might understand what tempering does to a blade.

The evidence presented is simply manufacturer recommendations and user accounts. There is no quantifiable data available as far as I am aware of. In my experience with a few 3" and 4" coil woofers with various power ratings and motor strengths, there is a noticeable difference in suspension stiffness after some play time.

For me personally this is just how I do it. I give things with mechanical parts a chance to wear in before I hammer on them. Perhaps this comes from building engines when I was a kid, but either way it is what it is. If I spend a thousand dollars on a speaker, I'm intending on taking care of it and using it for a long time. To me, spending 15 minutes playing some test tones free air to listen for mechanical noises is part of my "receiving process". I set my gains with the speaker disconnected, and I do listen at lower volume for a period of time before turning it up. The beehive 18 I have now was given more time than anything else to wear in simply because it is irreplaceable. It got a full 10 hours of 500w playtime, then another 10 hours at 1000w, then it was pulled from the car during a baffle change and tested free-air at around 1500w before going back in the car and dailying at 2k. Would I consider that normal? Not really, but it didn't inconvenience me one bit.

Playing it safe isn't a bad thing sometimes. I'm not going to advocate being overly careful in everything you do, nor do I nessecarily see an issue with someone being cautious in their life. Everyone can do their own thing, it's their choice.

Do all loudspeakers need a break in? Nope. Do some need a break in? Possibly, so I'll follow manufactures recommendations just like I would when buying a car, or a motor from an engine builder, or putting together a new seal assembly for a $65,000 machine. You do you, and I'll do me. But I certainly don't want to not speak up when someone asks this question.

Matt
Based on this and your other posts I'd bet my life you've never seen the inside of an engine, never bought a new car, and never installed any seal on anything.

Oof tough break man.

Not quite the inside of an engine, but I haven't had to pull this one apart yet.

So, ya going to off yourself now or are you done being a pessimistic, argumenitive, little *****?

Trying multiple times to make a comparison that he can relate too means I'm Eli5-ING some shit. Sue me if I don't sound like a harvord professor.

Oh and for shits, here is the machine that that intensifier pump powers.

Oh, and here is the sorento after a trip into the Ocala forest. Not super dirty or anything impressive, just the same car in a cracker barrel parking lot.

Is it still a major speed trap area down there near 301?
I'm not sure. My Ocala route is 40 and 326. We went off into the forest on the "marked trails" off of 40.

It's nice down there. I'd blast through between Saint Marys Ga and Tampa. I always went 301. Nice low hills and farm lands. I liked it.

Not alot of cops on 40 usually. Stayed at a cabin on lake Kerr for a few days and the trip into Ocala was copless.
