Infinity IRS Sigma for 2K...Should I do it??


Hi all,

I have an opporunity to buy a pair of Infinity IRS Sigmas for $2,000. As you probably know, these list for $10K. I'm somewhat familiar with the Infinity IRS series, but that's about it.

Do these require a lot of power?? Could I find anything comparable for that amount of money?

This seems like s steal, but I need your advice.

Thanks!!

Thanks Beemer. I saw Epsilons too. I'm in California. My only major concern is with regard to power. They're going to be in a relatively small room so I don't think they'd need a TON of power, but what would you say is the minimum requirement??

Thanks again,

Dan
The Sigma tech sheet I have states 87db at 1 watt/meter.
Not the highest in efficiency. A good amp 150w/channel+ with high current reserves would probably be best. Plinius comes to mind as a good choice, as would be Classe. If these were a tad more efficient, I'd tell ya to try the Gamut D-200, which, IMHO is a really great sounding amp, however it is current limited. On my 10t's there was a problem with woofer control, although the midrange from the Gamut was spectacular!

Regardless of how good the speakers are ( and i'm sure that they are quite good ), you REALLY do need to consider their size if going into a smaller room. Larger speakers require more room to breath and focus. While they might be a great deal that you don't want to pass up, the bottom line is would the give you what you want in the room that you have to work with ? Even the best deal is no good if you aren't happy with the purchase in the long run. Sean

The Sigmas do need some room to do there thing properly as they do not sound that great at low volumes - they need a very good amp as suggested above - the Innersound and Electrocompaniet are also good high current choices. They are really good speakers and at 2k I would probably talk myself into givivg them a shot because you could easily get all of your money back or even more if they do not work out.
I was part of Sigma's design team and can tell you catagorically that Sigma is a fine speaker; however, it is influenced greatly by the power amp., other electronics and connecting wire. Sigma is slightly bass heavy in a small room, therefore, room size is of consequence. The speaker must be kept on tiptoes to keep it raised off the floor for cleaner, more articulate bass response. The system should be biwired for optimum results. Separate power amps will produce even better sound but the amp on the bass end must have high current capability. Sigma's impedance, as I remember, is quite low and will turn off mediocre power amps with flimsy power supplies and heavy limiting in the output stage. If you require additional input, let me know.
