I might get a lot of flak for this, but it needs to be said and backed up with proof.

I'm a huge fan of the old school ('92-97) LANZAR Opti series amps/subs. So I say this with love for this era LANZAR.

The records need to be set straight and I'm going to do my best to prove what I've been saying in past threads. I am in the middle of going through 250+ issues of car audio mags to find any/all reviews I can of the LANZAR Opti amps. So far what I have found is the Opti2150, Opti500TMS, Opti50c. I know there's a review on the Opti200/Opti2200 (which are not the same amps believe it or not). I want to set the record straight as to their output and what people say about them being WAY under rated.

This line/era of LANZAR is/was what got me into car audio. My first sub setup was two 12" LANZAR Pro's and a LANZAR LRX200 amp. So I saw this with love for this era Opti.

As soon as I get all the reviews rounded up I will post my findings.

I can't find the review of the Opti200/2200.

So I'm going to start with the Opti2150 from the April '97 issue of AS&S, pg 26-28. Everything I post will be direct quotes from that issue.

"If you are bulletproof can you simultaneously be lame? Sure could be, lots of cheap amps don't fail, but they don't hit either. The Opti2150 hits dead center. Rated for 75 watts, it puts out 76 watts just below clipping and just .0096% distortion. All the part and... ...pay off at 2 ohm stereo with an almost perfect doubling to 141 watts and .0235% distortion. The 4 ohm mono reading should be 141 + 141 and turns out at 280 watts and .0245%. This performance happens at any battery voltage above 11 volts and that's what tightly regulated means."

Opti500TMS
October '95 AS&S issue, pg 31-32
"The high power numbers were outstanding; .010 at 2 x 260 watts into 4 ohm stereo and 2 x 507 watts at .020% into 2 ohm stereo. The 4 ohm mono results ran 1030 watts at .080% distortion. The guys at LANZAR said to do 2 ohms mono... ...even on this large a heat sink, requires a fan when driving 2 ohm stereo or less."

Numbers were not given at 2 ohm mono other then they said "Dynamic power was 2000 watts... ...draws 220 amperes at full power."


Opti50c
November '95 AS&S issue, pg 30-31
"Typical numbers for dampening like 200-500 are good and common, and anything over 100 is adequate but this amp does 16,000 and the power supply is like I said, tightly regulated. This combination of near perfect specs shows up in the power output like this:
4 ohm speakers/watts per speaker/ watts per channel
-------1---------/---------37--------/---------37---------
-------2---------/---------37--------/---------74---------
-------4---------/---------34.5------/---------138-------
-------8---------/---------32.5------/---------260-------
------16---------/--------25.5-------/--------408--------

All this power would be useless if distortion or noise was high, but the distortion was excellent at .0094% 1watts/1kHz and .028% 1watt/5kHz. Full power numbers at 4 ohm 37 watts ran .013 and even .25 ohm 408 watts was only .30%."




With this said, these amps ARE NOT WAY UNDER RATED, but infact almost balls on dead. I love these amps and they're built like tanks, but lets stop this over inflating of their power output.



Now, for you old school MTX THUNDER peeps, those are under rated. A review I just read a Thunder2300 did 876 watts x 1 @ 4 ohms, MTX rates this amp at 600 x 1 @ 4 ohms, 750 watts dynamic and at .018% distortion. Another review I read on a 2160 did 494 watts x 1 @ 4 ohms. Distortion I don't recall. Lucky me, I have an 2300, but it needs repaired. At least I know what happened to it and how to get it fixed.

I also have an Opti150 in working order, but would like to find that (I believe it's the Opti200) review of the Opti2200/200. IIRC the original Opti releases were unregulated. ???

Just found a review on the Opti2100 in the CSR Jan/Feb '96 issue, pgs 91 and 92.
As the others very tightly regulated so the 12v and 14v powers are the same.

33.3w x 2 @ 8 ohms
64.1w x 2 @ 4 ohms
122.7w x 2 @ 2 ohms
246.7 x 1 @ 4 ohms

This little bugger had a higher average output above rated then the others at 4 ohms x 1 ch.

I have an Opti-100 Plus and an Opti-200 Plus, both mint condition. I am a very big fan of these babies. Good luck in your search man.

LOL< I think these and the White Mean Machines from Autotek will have always have a place in my heart till the end of time. Zed is so the man :bowdown:

Zed is not responsible for the Opti series amps we love.

In about a month ot so I'll be looking for an Opti100Q.

Just had to add,

I didn't find the 100Q, but I did find and bought the Opti160.

I'm trying like hell to find a review on it.

I had 5 of the Opti 2200 in my Sable when it competed back in the day. Rated for 100 x 2 @ 4 ohms and 200 x 2 @ 2 ohms or 400 x1 @ 4 ohms mono. They were all hand tweaked by Dan Laufman the engineer responsible and Loni the lead tech at the time and another engineer that worked under Dan.

Love these amps they were powerful clean and dynamic. I did have the front end modified with different op-amps and the rail voltages were tweaked to optimize output for the load being driven. 4 of the amps were about 440 to 460 watts before distortion started to rise, 2 were set up for 4 ohms mono, and 2 for 8 ohms mono, the fifth was optimized for 8 ohms stereo and running horns and was capable of 60 watts x 2 @ 8 ohms.

My 2nd big time stereo install was an all Lanzar system running in my '92 SHO. In 1995, I believe. Had a 200 and a 160 for 2 sets of Pro 5.25" components and 2 12s.

They were, indeed, quite good.

I actually still have those 5.25 components laying around somewhere. I'd sell them cheap to a fan...
Looking for a set for the wifes car.

PM me, let me know how much.






I just got the install done last Monday, had to get a set of coax's for the time being, but am going to go with a set of comps eventually and those 5 1/4" comps would be perfect.

Here's her amprack.

Gotta love the old Opti gear, my old boss was a big fan. Ran an Opti 50C on six 15's in his Beetle, back in the day.

Found another small review for the Opti4100.

CA&E May 1997, pg 94

So tightly regulated that the output at 12.5v and 14.4v are the same.
56 wpc at 4 ohms,
THD- .055%
170w x 2 @ 4 ohms bridged
S/N- 100dB min gain, 99dB max gain


For an amp rated at 25 x 4 @ 4 ohms, this amp does way more then rated and as you can see by the other reviews, it's not normal. Just goes to show not all models are the same.

Is this the opti 500 tms you are speaking of SM?

I can't remember what TMS stands for, but yours is not a TMS. It would say TMS on it in place of "plus". It's not really a big deal, one isn't really better then the other.

From what a Lanzar tech told me back in day the TMS were more stable at lower ohms.

I might get flamed by the Orion boys for this, but we "tested" an Opti 50C against an Orion HCCA 250 Digital Reference back in the day ~ 1997ish? The testing was made as fair as could be by a bunch of "kids" messing around with car audio. We wired up four 12" Earthquake subs all in parallel and bridged the amps for 1 ohm mono. The Opti 50C had a tighter snap to the bass and also hit harder. It made believers out of all of us that day.

I'm on a mission, I ran into the old installer from the company that use to sell LANZAR over Christmas and he told me that they made a FEW Opti100c's. I thought he meant 50c so I questioned him about it, he said no not the 50c, but that they actually made a few Opti100c's. He said he saw one, so now a LONG hard mission is now under way, to find an Opti1000c.

I have a CSR that has specs for everything release in the past few years in the mid nineties. I will look for it. I hope to contribute to this thread a little.
