100 clean watts each means your amp was able to do 150 watts per side, and only running at 75% correct?

or did you clip yo signal?

 

The amp is rated at 100wpc and I had my gains set by a pro using an o-scope, so I doubt this was the issue.

Sorry to hear that man!
I listen to mine pretty loud and so far no problem for over 5 months now.
I got mine BP 250hz - 5000hz @ 24db with 100W each. Awesome sounding midrange driver. Hopefully, you can get your replace. GL.

250hz, wow I didn't realize they could play that low. I've tried mine briefly at 315hz but was afraid I was pushing them a bit too much.

They may not be blown. With all the extra output you were rockin' ,maybe you just knocked something loose down there.

 

Damn, I was running mine 150Hz 18dB with no problems! Now I've got them at 200Hz, 24dB but I think they sounded better at 150Hz. Perhaps the fact that I'm using a third one as center is taking some of the "load" off ?

 

So I’m gradually getting my system dialed in, and as a result of the good sound, I seem to be listening to it louder & louder as well. Yesterday I was rocking the **** out to Porcupine Tree on my way home from work at the loudest level I’ve ever turned mu HU up to. Today I get in and notice distortion in my mids, more so in the right one but also in the left.

I’m wondering how others are running their L3SE’s. Mine were in externally vented kickpods, 100w each, BP’ed at 400-5000hz, 12db slope on both ends. I figure I should have run 24db slope on the low end but I liked the way it was sounding at 12db.

Thermal overload.

Setting gains with an o-scope is not going to guarantee that you aren't over driving a speaker in that 75-100% master volume range buffer we leave.

I think you simply over saturated that voice coil.

 

What do you mean by over-saturation? Over-excursion?

I meant "blown" in a general sense. I don't think they're really blown per se, but obviously something has happened to them. I'm going to pull them out this weekend and see what I can find. Anything I should be looking for in particular?

 

Look for discoloration at the terminals, for starters.
If there was excess heat being generated, then looking at the
terminals is the least intrusive way to get a first impression.
The SE's have that lovely phase plug sticking out, so you should
use your sniffer to check for any charred aroma.
Examine the tinsel leads that run from the terminals to the voice coil.
Again, look for thermal discoloration on the tinsel leads and on the
terminations at the voice coil bobbin.
Check to see if the cone movement is unhindered. Use your fingertips to
press evenly on the surround. No sense in using one finger, because all that
will do is cause the voice coil to rub against the pole piece.
When you're through all this, then put some power to the speaker using a tone generator. LOW VOLUME, LOW POWER. Run tones from 50 hz on up.
You're not trying to listen for music, just listen for any scraping or buzzing.
If there is scraping/buzzing, take the speaker off the power, and use a really thin bit of stiff plastic film to check for debris between the phase plug and voice coil bobbin.
I've repaired countless drivers over the decades, and the above procedure is one that contains most of the non-destructive tests required for processing warranty claims.
I've only got L3 (non-SE) in stock right now, so I can't tell you the exact material
thickness necessary for the last test.
Good luck with the remedies!

 

ok, thats definately possible. Actually, its probably likely, since the highpass is so high.

 

I’m running the L3SE’s off a JL slash amp. I’m assuming that with their regulated power supply, it’s putting out a consistent 100wpc at 11.5-14v and not being overdriven. Gains are set very conservatively, and my HU (P99) is allegedly capable of sending a clean signal all the way to max volume. Based on that, I’m assuming that I wasn’t in a position to overdrive the amp or speakers, but I guess it’s still possible.

I still need to pull the drivers out, but it’s definitely in the speaker and not something external. The cone seems to move freely and I don’t hear any scraping or smell anything. I’m hoping it's something fixable.

 

Any updates?

Your P99 will send an unclipped signal at max output IF you're working off a flat response...at least that's how my P-01 works.

I'm working with 230 x 2 on my L4SE's. They handle the power on a 24 db slope down to 150 Hz.

Gove Bob Morrow a call. I believe he's your rep in the area.

 

is this a case of when you send a lot of power into a coil and the only thing keeping it from melting down is the little bit of excursion making a small amount of air exchange, then you shut it down and the hot parts surrounding the coil allows it to deform before cooling down?

really sounds like too much power for too long a duration.

You mean "carry over" heat like when you cook a roast, only the inverted version?

 

That's a pretty conservative crossover for the L3SE. Let us know how we can help.

 

I have played my L3's at 200hz-6k @24 db slope off 250 watts, Played them so loud in my in my old F150 SC, I could hardly stand it.... Never an issue.

I hope it gets resolved for you!!!

The best thing to do is Contact Scott Buwalda.

 

^Agreed. Drop a line to the designer.

 

Finally an update to this...

I never found anything physically wrong with these. Next, I took them into my HAT dealer. He agreed that they sounded scratchy & distorted. Fast forward a few weeks and I'm eyeballing a BNIB replacement set. No warranty hassles or implications of improper use whatsoever.

Kudos to HAT & Buwalda for standing behind their product & warranties!

 

That's good stuff man!

 

This is THE reason we use brick and mortar dealers.

..and the Dr.? He's a standup kinda guy. I know, he took personal time to listen to me while I was down and out in Iraq. He gave some attention to me in some group buys that were limited to Team Hybrids.

I am honored to deal with Scott Buwalda.

 

Wow,

I am running mine from 315hz (24db) - 4khz (12db) and that is impressive.

Be happy to have purchased HATs. The best service I´ve been in contact with.

 

oh man, this is eerily similar to what happened to me.

I run the P99 as well and had to get my right L3SE replaced. I was running mine at 400hz with 24db cutoff. Sounded really scratchy, but nothing was apparently wrong with it by looking /smelling etc at it.

Was warranted with no hassle though.

 

This one still baffles me a bit. Nonetheless, glad to hear you were taken care of by the powers that be at HAT!


On a side note, my L3SE's run 250hz-6.3k at 24db slope in the pillars alongside L1R2s picking up the duties on the top end. No issues(knocks on wood) thus far.


Cheers

 

Hi.

I just bought the L1 Pro R2, L3SE and the L6SE. Can you give me an advisce for the L3SE? Where i should it it start running at and what should be the end frequency for the first start up?

 

Where is the placement you're thinking of for all the speakers?

 

I drive a E-Class 2007.

The tweeter will be in the a-pillar ant the L3SE in the reflective triangle(?) Sorry but I am german and do not know how you say to that corner in the front door near by the mirror.

 

I'd seriously look at moving the mid down to the kick area. Having that mid so slose to your ear isn't the best idea.

 

I don't see using the "sails" for mids being a problem... Scott uses his L3SE in the sails of his G35 - you should know that

Kelvin

 

Okay...go for it. Have fun.

 

Do you have a link to a photo of the sails?

 

You give something to get something...

What are you giving away to have the speaker so close to your left ear?

You're going to say nothing...and you're wrong.

Krotzn's setup is NOT scott's setup either. Krotzn, what source and processing are you using?

 

I have two Audison Thesis Quattro, Audison Bit One, Audison DA 1 Bit
