Hi,

I own a the "t.amp Proline 3000" and with that i power 4 "Fane Colossus 18XB-8 Ohm", 2 per Channel (parallel) which give me 4 Ohm per Channel.

I now wondering if it is possible to ad 2 more "Fane Colossus 18XB", 1 per Channel, so that i'll play at 2 Ohm per Channel?

t.amp Proline 3000:
2x 1500 W at 4 ohm
2x 1100 W at 8 ohm
2x 1800 W at 2 ohm

yes you can do that but no i would not suggest it. your amp should really have more power then the rms of the speaker so if you ran 4 fanes a side you would get no more sound or maybe even less sound as each driver would be majorly under powered. either buy another proline or get a bigger amp to run 4 per side.

hope this helps

Okey thanks.

Can you help me understand what happen with the RMS when speakers are wired in parallel? I have never knew what will happen, are the RMS increasing or will it stay the same as one speaker?

For example:
Two 1000Rms, 8Ohm subwoofer in parallel = 2000Rms, 4Ohm

Or

Two 1000Rms, 8Ohm subwoofer in parallel = 1000Rms, 4Ohm

Two parallel subwoofers 1000W 8Ohm will give a load of 2000W on 4Ohm.

And putting 4 Fane's on one channel of your amplifier will add 6 dB more SPL. But the power send to one Fane will be less, i.e. 450 W instead of 750 W, which is a decrease of about 2.2 dB. Your total gain will therefore only be 3.8 dB.
Mind you, this is a theoretical value, it is probably less (< 3 dB). Thereby the sound quality will decrease because the amplifier has to take control over now 8 huge speakers instead of four. A real 'tour de force'
Buying a second amplifier will give you, with the same four speakers (two speakers put on one amplifier in bridged mode = 1800 W / speaker) a gain of 3.8 dB. Taking power-compression in account, the total gain will be < 3 dB.

But both options give you less then 3 dB gain, which is IMHO not worth the investment, but the 'second amplifier' choice would the one I would go for if necessary.
Only doubling your complete set (speakers and amplifiers) will give a noticeable 6 dB gain.
