Curious about Amp for Legatia L841-3 active?

[Smondo17 0]

What amps do you guys use when you need 6 channels of power for this set of speakers? Or do you mostly break it up with a 4 channel and a 2 channel amp?

What kind of processing do you have available?

Zapco D650.6 would be my suggestion if you haven't already purchased processing. It has digital crossovers you set with a computer.

I want the h701 combo. Just curious about amp selection.

If you want to go active with a sub (3way+sub=4pairs of RCA)

Try to know if your headunit has 4 pairs of RCA... (Clarion DRZ-9255, Alpine F#1, Pioneer P9 combo, etc...)

Then you can go with 6 channels (front) + sub amp.

If not (3 pairs of RCA), then you would have to go with a 5 channel, or a 4channel + sub amp.

However, I believe that the Audison LRx6.9 (6 channel amp) can be used as a 6 channel amp but using only 4 x RCA inputs.

Then you would be able to go with 6 channels + sub amp only from a 3 pair RCA head unit.

Might have other amps that can be used like that but I can't think of any.

Hope that helps,

What are some good 6 channel amp choices? To bad sundown didn't make a 6 channel. Especially if it put more or less powers out on certain channels.

Zapco dc series 650.6. It's not cheap but has amazing crossovers, tuning.

I think it does 100x4 @ 4 ohm and 180x2 iirc.

How much room do you have? Might have to go to something like a 4ch amp + a 2ch amp

Thats what i was thinking. Its just something i am curious about and was wondering what people with 4 way active tend to do.

I'm going to be running 3 2-channels. I'd run a 6 channel if there was one that suited my needs. If you can find an older Phoenix Gold XS6600 it is a staggered power 6 channel. PPI made 2 a while back that were really good as well.

basically, it depends on your goals, I like a lot of over head, so I will be running a sundown sax-100.2 on each driver. IMO that is by no means necessary though, a sax 100.4 and a 100.2 would def. be sufficient, but I like to get plenty loud without pushing my equipment anywhere near their limits.

I like a lot of headroom, too. 100w per channel is plenty of headroom for me.

I like a lot of headroom, too. 100w per channel is plenty of headroom for me.

Most of the time it's a bunch of two-channel amplifiers to run an active four-way system. I'd highly suggest vertical biamplifying the midrange and treble with a fully-active system.

Refresh my memory on the term "vertical biamplifying" please.

If you're going to be running the L8's, then 400 watts each should satisfy.

Why not a pair of 4 chn's, you could use the extra 2 channels for your sub/s

Sorry for the late post... I've been outta town for a while. Catching up!

Last year I used combinations of 4-channels and 2-channels for the front stage.

Left side was:

4-channel bridged to 2 -> L1 and L3. IIRC that gave me 125 each

2-channel bridged to 1 -> L8... something like 500 watts there

Same setup on the right side.

This year it is all two channel amps on the front stage - 300 each on the L1 & L4, then bridged for 1000 on each L8.

Mostly just looking for headroom with the big wattage.

Edit - just realized I didn't help you much there...

Tell you what I look for in a nutshell though.

In my opinion, irrespective of brand name:

50 to 100 watts on the L1

100 to 150 on the L4

250 + on the L8

However you can get there is entirely up to your budget and installation space. You can get by with less wattage on the Legatias, but for competition the headroom is a significant plus.

Man I feel like a noob asking this but how do you set up headroom:

- Set the amp gain as usual? 50 to 100 watts on the L1, 100 to 150 on the L4, and 250 + on the L8

OR

- Set the amp gain to something like 100 to 200 (L1), 200 to 300 (L3), and 500+ (L8)?

And play safely with the volume knob...

sorry for the stupid question

[helotaxi 46]

Headroom is simply having more power than you need to get as loud as you want. It allows for full dynamic range from the system and it also keeps the amps operating well within their comfort zone so you don't have to worry about approaching clipping or finding the point of rising distortion prior to clipping. You can set it up with judicious use of the volume knob or with conservative gain setting or a combination of the two.

Thanks... Understood now
