Weight isn't a problem for me, majority of the time rig will be used at one venue not far from my storage. However I think I've been sold on the QSC PL380 it does everything I need and can be bought brand new.

I'm pretty new to the whole Soundsystem thing but am I right in saying as these cabs will be wired in parallel the speakers will essentially have 4ohms of resistance meaning I could run 2 horns/channel of a Crown Xti 6002(this is the height of my budget)

Is there any other amps I should considering? I'd like to keep it easy to source, and im reluctant to buy second hand.

Thanks



Is weight an issue my man?? When on lower budget multiples of the heavier stuff always prevails! The issue you have is with your drivers needing so much juice it pushes you towards needing the big dogs like powersoft to use multiple of them on one amp! 

I don’t see 2 prolines, 1 bridged to each 2 drivers, not being up to the task! Just use a good limiter or don’t thrash and have an eagle eye! 

2 4050/5050s  too!

Or as others have said and many hate to admit, people have had good experiences with CVR, Admark and Morin

You don't have enough posts yet.

QSC PL380, could power 4 ohm driver per channel no Problem.

I have 2x of these for sale.

I feel like breaking stuff when I hear the compressor on Radio 6 messin with Miles, I would quickly become very enraged if my amps started softening my sub bass.

Pretty much all limiters embedded in the amplifier's circuitry will start to soften the bass once the amplifier approaches its limit. That high degree of amplifier distortion (which is favored by some), which would only get louder, once you push the amplifier harder into clipping is not present anymore with modern-day amplifiers. 

Best Regards,

I feel ya, E.T. Just like driving aids on modern cars, these "effects" are angelic to some but the devil to others. I would prefer my electronics to allow my ears to be The Judge.


When the clip lights are not solving the problem and, the customer does not know how to use his/her own judgement on when to back-off, the manufactures have to resort to on-board limiters.

This is video taken, from my gig in 2013, with Powersoft K20 on proper 32A supply, powering 4x of my design Scoops, with "then" PD1852 prototypes.

3 Phase distro with meters, records the excitement..

Feeding the amplifiers proper power has always been something many never pay attention to.

Thanks Elliot.

What is your opinion of the ITECH 12000 HD?

Heard good things about the sound and power, but they are now almost impossible to repair, hence very scarce !?


It's discontinued by Crown. The voltage rails are around +/- 205 volts so, they still fall short in terms of output power compared to the discontinued Powersoft K 20 and, the current Admark/Morin/WASI amplifiers that all offer around +/- 220-230 volt rails. 



Best Regards,

They discontinued Macro-Tech 1200i by Crown. Its the same power as the Itech 12000 HD. The voltage rails are around +/- 205 volts so, they still fall short in terms of output power compared to the discontinued Powersoft K 20 and, the current Admark/Morin/WASI amplifiers that all offer around +/- 220-230 volt rails.
