Hey guys,

Was just thinking about doing the following,
Sinfoni 90.2x bridged (350rms) to an SQ sub (Shortlist at the moment will be either a Helix Competition 12 or 10 both rated at 350 and 300 repectively) and a Sinfoni 45.2 to run Rainbow Vanadium splits.

Do you guys think this is a good move? I want to have a boot install done by Hakki in the next 2 weeks or so and i would like to keep the amps the same brand.

For sound quality purposes, do you think i am running enough power? 350rms for a sub seems ok to me but then again i have been using a 600rms woofer for the last month with 850rms on tap...... Also, will 50rms for the Rainbow's be adequate??

more power sounds better NOT louder.

2 x 50watts rms to a high quality set of splits.....

1 x350 to a sub.

for me that would be very much on the low side of the power i would be looking at.


if you were to run 3way active then the 45.2x on tweeters, 90.2x on mids/midbass and a bridged 150.2x on the sub.


or

bridged 45.2x per each side for you splits and a bridged 150.2x for the sub.


or

dual 150.2x stereo to the front splits and bridged for the sub. That willl look the best too

If you want things to be the same brand, and you already have a helix sub, then why don't you get a pair of helix amps?

An A2 Competition + A1 Competition would make a brilliant combination, will probably cost similar money to the Sinfoni (if anything, prbably a bit less). Should be at least a match for it in terms of sound quality too, maybe even better.

From memory the A1 gives about 1x300, and the A2 gives about 2x150 - heaps.

Depends on the sub - if it's even reasoanably efficient (~85dB-86dB @ 1w/1m), then 350w is more then enough for SQ use. In SQ use, you'll usually be using 50w-100w during daily listening if that - any more then 300w 'headroom' is just a waste of power imo. I'm running about 75w @ 8ohm right now to a moderately sensitive sub and it has no trouble keeping up with the fronts.

i think it's enough power, particularly from quality amplifiers that should have plenty of grunt/headroom. i'd love to try Sinfoni one day; i just can't justify the cost to change amps.

i wish i had a local store like Hakki's, filled with Sinfoni and Brax/Helix gear. :D have you had a listen to Sinfoni splits, rather than Rainbow? curious to know your thoughts.

My mates Subaru Liberty has Sinfoni splits in them (its the dark silver one on Hakki's website). Not too bad at all. I think they are the entry level ones though....... They do sound quite nice but dont seem to have the force that the rainbows have. Still i wouldnt turn them down if i was offered a swap :rolleyes:

Preferred the Rainbow's myself.

Heard the Sinfoni's one time and they weren't bad speakers, but I felt the Rainbow Profi's were just a smoother, and more life-like. To be fair though, I never herd them side-by-side (different cars, different times) so install and positioning could have played a part too.

I just felt that the Rainbow's sounded so clear and effortless, while the Sinfoni's seemed a tad more vague and restrained.

Those Rainbow Profi's really were very impressive set of splits for the money (I got them for under $1,000 at the time, from memory).

Oh, and did I mention that Sinfoni amps are drop dead sexy???

I'm actually going to be in the market for a new amp myself in about a month's time, and I swear I'm unbelievably tempted to buy a Sinfoni just to sit and stare at all day. I swear you could display one on a wall, they are so damn gorgeous.

Only reason i'm 50/50 about putting them on my shortlist, is that I'm concerned they may sound a little coloured for my taste, compared to something like the Helix I'm using now.
