The crest was probably outputting over 1kw more.


Fixed it for you.

I just looked up the crest cc5500 and compared it to the pro 200 line the crest 9200. According to the website it looks like the pro 200 line amp the pro 9200 would outduel the cc5500? Is that right?

Yep, the 9200 has more power everywhere. But, even used it's double the cost of the 5500, but it's an awesome amp!

You can tell from the 5500 specs that running stereo both channel driven vs just one channel (not bridged) that its power supply is limiting it. The 9200 might be what the 5500 could do with a class d switching power supply.

If you can afford it over the 5500 and want the extra juice, I say go for it.

I have 2 of the 9200 and 3 of the 8200 crest amps. I have 3 DTS 10'S with the LMSR UPGRADE. and in the latest James bond film on the subway scene I noticed my amps clipping and cutting the bass off for a few seconds. Does that mean the amp is overdriving the lmsr drivers? That is the only scene Ive seen that happen in. Mt 3 DTS 10'S are powered by the 9200 amps.
post #636 of 758
Sounds like the opposite to me. More like the amps can't keep up with the drivers. Somebody with more knowledge than me will can answer better.

How do you have them wired to the amp?

will this sundown sub(X18 D2) work in this design? i just dont see myself spending 1k for an lms ultra

If the sundown isn't a candidate, the Mach 5 audio uxl 18 is several hundred less than the LMS and proven to work in this horn.
post #639 of 758
I've got the UXL's in my G-horns, they work great and pound like mad!
post #640 of 758
N8 do you have both in use or just the one?
post #641 of 758
Just one in use right now, the other is in my workout room under a bunch of boxes lol

I was just about the grab a pair of LMSs for the GJALLARHORN re-fold, but can't wrap my head around the cost. So, I keep coming back to the UXL for not much more than half the cost!

Did you get a chance to compare the two?

I can't really comment on the two G-horns but ... from what I know of the differences of the drivers, I'd bet that the LMSU would have a slight advantage at the very very edge of the limits of the system.
post #644 of 758
The UXL is about 95% of what the LMS can do, so you won't be missing much.

I am sure you are correct in that regard.
However, I was curious if there was an audible quality/tonal difference in the two when used in a horn config...during "normal" listening levels. (whatever that means in this forum!)

I'm skeptical...

Josh stresses the importance of the motor force of a driver for use in horns, and the LMS has over 20% more motor force than the UXL.

Does a 20%+ stronger motor really only equal 5% more in performance?

Most likely nothing. Most of the difference will be 50hz and above and at the extreme end of the throw of the driver(s).

Agreed. Both get the job done in a small cab. So close it could be said that the UXL is 95% of an LMS-U wink.gif that is until you start injecting high level <30hz content. smile.gif

That's where the $300 difference comes in and the LMS-Ultra takes the lead and keeps it.

When doing the math, 95% actually kinda sucks...lol

For example, one GH with a LMS can do 120db at 20hz. 95% of 120db is 114db...6db less...

6db is a doubling of both the subwoofer and amplifier. Meaning it would take two GH's loaded with UXL's and each fully powered to match a single GH with an LMS...

YOLO

get one lms...build one enclosure...get hooked.

then the second won't be painful at all. :-)

Of course, you are assuming that you are running them all at the max limits. I would assume that most people are not pushing most subs that hard.

Yes, and I also have no idea what the UXL numbers would be and this is all just pure speculation.

However, I'm sure most don't push subs that hard, but I most certainly do!

Lol! Yeah really but... audio doesn't work that way. 5% less of 120dB (at what, where? wtf!??!) is not suddenly 6dB less. Wait ..... What are we talking about again? tongue.gif

Mmmm, no, not necessarily. In the end it's your call.

How bad do you need to save $300? How long do you think you'll keep the G-horn? Over a year? Several years? Get the Ultra. cool.gif

Good point, that's how I typically think as well. But, sometimes I need to force myself to think more rationally sometimes, YOLO, but I ain't printing money either!biggrin.gif

You know... I'm just thinking in a way because I know you and you already have experience with the Ultra and loved it. Another would make sense. Also I never get the feeling you are on a severe budget so a $300 difference even over a years time is ... not all that much.

Now if you're coming in here saying, "hey I want to build four of these horns but I don't have all the money in the world" then I'd think that the UXL would be the perfect choice.

In this case....

I hear ya. Yes, the LMS is bad ass, no argument there. smile.gif

Damn you all! I guess I have to order an LMSU....Ugh!

That not how it works. It's not a fixed 95% number. If you look at their numbers, the LMS leads in a lot of ways but the UXL also put up a great fight and wins in some also.

I'd also like to point out, I don't think anyone has had direct LMS vs UXL experience in a G-horn, myself included. Both drivers can take all the power 1 channel of a clone 14K can give and I'm sure both are awesome!

Yep, it doesn't work, hence my comments earlier about it being speculation since I have no idea would the UXL number would be.

But, it got your attention, and it just goes to show how "95%" is also pure speculation.

"I hear ya. Yes, the LMS is bad ass, no argument there.

+1 for the Ultra. Better make it 2 since making the two horns at the same time is really going to save you some time. Don't fight it Jpm - you obviously want face-melting LFE, get started with your G-horns already!
