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.
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."
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."
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
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. ???

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.
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.
In case anyone is interested, I'm about to sell my entire collection of Opti amps. Some are new in the box, some are almost-new in the box (slightly used, less that 200 hrs), some are out of the box used and some are not working.
If anyone is interested in anything, please let me know.
I'm at work right now, but here is what I can think of off the top of my head:
(3) 2200's (one in the box)
(2) 2150's (one in the box)
(2) 4100's (one in box)
(1) 4150 (in box)
I can give a full status of any amp if someone is interested..
