Need help choosing LP amps for a 4 way active SQL setup.

1810 Views 22 Replies 7 Participants Last post by  nigel1977
I am officially on a quest to run all LP amps for my SQL system. Need to know which of LP's amps are the cream of the crop, which (if any) to avoid, and finally what to pay for anything from a beater to a clean example of any given model (need a pricing guideline)

I need for a 3 way active front stage
1) 100 x 2 @ 4 ohms (tweeters)
2) 200 x 2 @ 4 ohms (midbass and midrange)

Also need to power 4-12W7's at their peak, would like them to see 1000 watts rms each (since I am not too familiar with LP's lineup, I am open to suggestions.)
2- LP amps to power 4- 12W7s to their limits, 1 per pair @ 6 ohms?


I don't care for their physical appearance, will consider beaters as long as they are pristine inside. Prefer them that way if I can get them much cheaper.. These will not be put on a shelf as show pieces, these will be used and pushed hard, all day everyday.. I don't care how they look, I care how they perform (I write this in case there are some of you considering selling, maybe you have a beater that fits my bill that you are considering selling?)

Now before you all start commenting on the gross imbalance of power I am seeking ( 4-12W7's @ 4000 watts vs 500 watts for my front stage) consider this.. It's my ****, I'll do what I want with it :)

Truth is, I am not trying to match full output of said sub section with said front stage.. The ludicrous sub numbers are purely for attracting chickenheads.. Down here in Soflo, if you are heard 30 seconds before you arrive at the scene, all the bitches want to know you. Having said that, when listening to normal music, the subs will be tuned for seamless blending (more than likely be off or near 0..)

However, when Bass Mekanik gets thrown in the mix, I would like to be able to flex the muscles and get the shorties breaking necks to see who's coming (this doesn't involve trying to match front stage to full sub output. Get it?)

All I can say is, good luck and I hope you have a deep wallet.

Even a junk 8002SW, 3.2HV or 4.1HVS, still command high price tags. The 2.2HV I sold recently, I probably could have gotten about 600 cash for it, and the 2.2s are much easier to find than what I listed, and the 2.2 is still hard as heck to find.

And you really don't need the amount of power you're looking at for your front stage, which means you can get the slightly smaller amps, for a bit cheaper plus they are easier to find.

The 652I I have on my tweeters, is PLENTY for tweeters (32.5W per channel) a 992IQ or 1502IQ will be plenty for midranges, and something like a 2202, 2502 or 2.2HV will be nice for midbass.

Your sub amps, are going to be very hard to find, the big dogs are rare and pricey.

If you're willing to pay, a guy around Sarasota has two 8002SWs for sale, think he's asking close to 1k per. He has em listed on craig's list if you want to contact him. I just rechecked the listing, he has 4 and wants 5k for all 4, all of which have been modded.

Thanks for that!! I needed to be reminded that LP's are mucho dinero.. Junk meaning what, beat up looking? Is ther such thing as a bad LP amp? Are there variations, some better SQ than others? I don't mean power, I mean SQ.. I have a shot at a 5002IQ. That may be my first LP amp.. Does everyone agree that they are worth the money? I have never even heard them.. What is a tonal trait that they are renowned for? Are they laid back, Up front and bright, neutral reference accurate, tube sounding crunchy?? How would they be described?

I enjoy amps that sound effortless at any level of playback.. I like what I describe as a full bodied, weighted, dynamic feel, an amp that seems to not run out of steam and handle transient peaks effortlessly.. I know the amp alone is not responsible for this, but in an A/B comparison between a few different amps, I found a winner in the crowd for subs, a different one for midbass, yet another for mids and highs.

Anyway, I am actually looking for that type of power for for front stage because I like the headroom it affords.. I haven't heard my L6's yet and I may be switching to an SUV for my full system.. If that happens, I may sell my L6's and go for a seriously potent midbass driver, possibly Pro Audio, something along the lines of EighteenSound.. I like kick drums and bass guitars in any type of music to be very prominent, in your face, up front, balls out, accurate and lightning fast.. My mids and highs I like a bit laid back for metal, a bit more detailed for funk and ambient or Eurotrash, techno, vocal etc..

In any even, I like having the almost overkill power on reserve, makes for a better listening experience when the track is very dynamic and played at a moderate to serious level of output.. I don't like clipping ever.. Effortless sound with no listener fatigue even at high levels..

Having said that, if I chose Pro Audio 8's for midbass, depending on the driver choice, I'd say 200 watts is plenty.. If I go mini subwoofer like a JL 8", I will need 300 x 2.

2 reasons why I chose the L6.

A) I needed a midbass that was a bit light in the ass, my Acura had a buzzing in the doors that I couldn't rid myself of no matter what (this is when I was running quad 6.5" midbass powered by 300 x 2) A midbass that was potent in the 50HZ range would cause intermittent vibrations, more like an occasional buzz at certain frequencies.. Drove me nuts..
B) I got offered a killer deal on the L6's with L1V2's, at the same time, I got an offer for mint L4's, so i figured all HAT Legatia for front stage for pennies on the dollar? Why not?.. If I hate them, I can always resell them..

Anyway, I will have 4-12W7's outfitted with the new rubber surrounds and new suspensions, essentially all BN.. Getting them all rebuilt from the mag up, even the 2 that are working.. This to ensure they all perform at their best..

I need good potent power, I may hold off on LP for subs till I get good enough to compete, but I will go LP for front stage..

I haven't heard them yet, they may be plenty, they may not make the cut at all..

I saw the listing that you are referring to for the LP's.. I may contact him.. There are a few out here..

I case anyone is interested, there is a Craigslist listing for a TRU Hammer. The amp is absolutely mint, I don't know the asking price, he didn't specify.. I think he is in Port charlotte FLA. Just Google "Tru Hammer" site:craigslist.org

I lost the link otherwise I would post it.. It's somewhere in FL, West Coast or up Central FL I think.. The amp looks to be museum quality, Gold, a work of art.. Wish there were 2 of them. Wish i had the funds..

DPS 350 for the tweeters. You can mod it or leave it unmodded, both will give you spectacular SQ. I would say a DPS500, but they are impossible to find and some joker got $610 for one in mediocre condition. You can buy a DPS350 for around $250 when they come up.

2.2HV for mids and midbass. I don't think there's any doubt there. The 2.2HV is probably the best amp you'll ever hear on mids and midbass. I don't know the exact figures on them but a 2.2 BLOWS AWAY an amp that was measured at 147x2. I would suspect the 2.2 puts out around 250w x 2. You can find 2.2s for $500, but not often. In good condition they are at least $600.

Contact Jason Winslow (thehatedguy) He did have two modded 3.2HVs and he was practically giving them away. I think he was asking $650 for them. Those should put out about 700 x 2. At one time he also had two 4.1HVs, one for an insane $750. They normally go for $1,200 or more. Those are good for at least 700 x 2 stock and more like 1000 x 2 modded.

I've seen those Trus for some time. He had three amps at one point. His prices were fair, but not a bargain.

Thanks Moobs. I was wondering about the DPS350.. Is that the one that comes in plum crazy? Someone offered a showroom mint one for $350.00 shipped.. I thought it was high, and wasn't sure if i should bother because it looks different than the "brick" type LP's that are most sought after EG: 8002..

I also have a shot at the 5002IQ (I think is the model number) Is that one worth looking into for SQ purposes? What would be considered a good deal if it is unmolested and in decent condition? (which this one appears to be)

Also, from what I gather from your answer, there are LP amps that are better than others in terms of SQ. The ones you mention are duly noted.

DPS for tweets, 2.2 for midbass midrange but I think the 3.2 would leave me short for subs..

For midbass, If I use the L6's and end up content with them, the 2.2 sounds perfect. But I may want to run quad 6.5's again, if so, I want to provide plenty of power, something in the order of 300 x 2 or a bit higher. Also, I run midbass from 63HZ to 200HZ only.. (delay issues, that's my formula)

Also, I want 1000 rms per sub.. I may not be able to afford the power that I need to max my 4-12W7's in LP's offerings.

Just in case, what should I look for? Should I run them in pairs @ 6 ohms and look for 2 amps that will provide well over 2000 watts rms?

Suggestions please!! I may have to settle for an LP front stage then slowly make my subs into LP as well..

$350 shipped for a mint DPS350 is a fair deal. I would get it. The DPS and HV series amps were the last and best amps that LP put out. Others are still excellent, but those are the ones I lust after most. If you want more power, a stock 3.2HV would give you more power than your misbasses could ever want.

I'm not sure about the numbers on the modded 3.2HVs. They may be able to put out the power you need for subs. Once modded, they prefer high impedance loads. They would have no trouble pushing their power ratings at 6 and 8 ohms.

As much as I love LP, I'm not sure you want to spend that much money for sub amps. I don't believe in SQ amps for subs. It's hard enough to tell the difference between one sub and another. I'm definitely sure that you can't hear the difference between one amp and another on subs. You would also need an upgraded alternator with that much A/B goodness. I would do:

DPS350 - tweeters
2.2HV - mids
2.2HV or 3.2HV - midbass

any good class D amp for subs.

Thanks Moobs..

Just got suckered out of a 5002IQ. The guy wanted $350 for it, when he realized that it was worth quite a bit more, made up some ******** story about how the thing dissappeared... Basically, he originally told me that he purchased the amp for $50.00. Then when I expressed interest in it, his story changed, told me that he knew someone selling it, the guy supposedly was asking $350. Then as my interest grew, the guy did his research, realized that he could get considerably more, made up a BS story about how the amps been sold..

Anyway...

The quest begins.. I am going to search far and wide for bargains on LP DPS and HV's. Thanks for all the 411..
I have 3 LP amps left. 1 black 2.2, one modded titanium 3.2, and 1 titanium 4.1. My black modded 3.2 and another 2.2 are leaving this week. My black 4.1s went to Japan.

The 2.2 left I have to find the bottom plate for it and it has a bent corner near the mounting feet. The 3.2 and 4.1 aren't cosmetically perfect, but work great. I will sell them, but I am not giving them away.

The prices on my amps were about as good of a "bargin" as you will find on the HV stuff.
Ignore me. I was smoking crack. The 4.1 is a mono amp. If you could find two, they would push your subs at 6 ohms with more power than you would ever need, but it's still a waste IMO. They are subs. Any reliable class D amp that makes rated power should work well.
Moobs, it's OK. Put down ths crack pipe and slowly walk away.. Class D on subs noted. However, I found a guy that has 2 of the 8002SW's completely done over by Ray at TIPS, both in nice aesthetic condition.. He has the proof of TIPS overhaul.. He may actually trade for equipment that I have.. I think one per pair of 12W7s's would be insane.. Out of curiosity, What does the 4.1 do? I need 4KW for my 4-12W7's, I could show the amp a single 3 ohm load by stepping subs up to 6 ohms in pairs, then combining the pairs as one in parallel no?.

Hated, I'm interested in the 2.2 the 3.2. Depending on what that 4.1 does, maybe that too.. Aesthetics is becoming a concern but isn't a deal breaker. PM me your asking and phone number, maybe we can work something out.. BTW, I got offered a pretty good deal on a pair of clean,same color, completely modded 2.2's . I'm like the majority, always looking to save a buck.. Let's see what you got..

People, we need to stop sending all those LP's to Japan, pretty soon, there wont be any left in the states. I know of one guy that supposedly had 70 of them, most went to Japan.. What's with those crazy Japs and the LP's? They stealing our tech for once??

I sent one of my modded 2.2s to Italy because no one here wanted it :(

Jason's prices are the best I've seen.
No one here wanted mine, and after getting jerked around by a few folks...I got tired of it. Was contacted by a nice guy in Japan who paid what I was asking for the amps and didn't try to beat me down on price.

LP's website still works, believe it or not:

Linear Power Specifications: 4.1HVS
LP's website still works, believe it or not:

Linear Power Specifications: 4.1HVS
I know it does.. But there is a difference in what he has listed vs what these things can really do.. I wanted "hands on, real world" feedback on how deadly that one is..

OK, so, does that mean they are all gone? What are you asking? Are they modded? 2.2 and 3.2. Modded? Not modded? How much?
Still have:

stock black 2.2
modded titanium 3.2
stock 4.1
I know it does.. But there is a difference in what he has listed vs what these things can really do.. I wanted "hands on, real world" feedback on how deadly that one is..

The ratings listed are pretty accurate, the 4.1HVs on 12.5V will do about 1300 watts @ 4 or 8ohms, probably 1500+ on 14.4V.

Linear Power amps aren't really cheater amps like the old Orions were, they're ratings are pretty accurate, and you really shouldn't expect a significant increase in power in a real life situation. The nice thing about them, however is that they are rated @ 12.5V, with a steady input voltage of 13+ their power will increase.
But modded you can probably tack on an additional 25% if not more to those figures. That modded 3.2 will likely put out more power than the stock 4.1. A modded 4.1 is probably up around 2000 watts.
2502iq is clean.
2202iq, I was not impressed with at all. Could have just been a bad one. but couldn't get any power out of it like I was expecting...
5002IQ, great amp. Repaired a few of them years ago, and they worked great on 15's.
3001-2 Had them in my car years ago. Really liked them.
952iq --- Get a dozen of them. Bridge one to each coil. Those are some super-super clean little amps. They pack a punch for sure. Would look neat too :D My favorite LP amp is for sure the 952. Can get them down to 15hz out of the box. No problem. Just in case you want it to go that low. I did some comparisons awhile back to see how low an amp can go before fizzling out. (I was bored) The LP 952 came in 2nd at 15hz...
Still have:

stock black 2.2
modded titanium 3.2
stock 4.1
OK the suspense is killing me!! HOW MUCH!!!!!!!!!!
