My New Speaker Setup: LSi Series

Hillbilly

I just purchased the LSi15, LSiFX, LSiC, and DSW 66wi sub home theater set up at www.acousticsounddesign.com. I previously had the Infinity Alpha series, which was a good mid-range set. The LSi series sounds incredible and they are beautiful, as well. There is plenty of power to spare. I did, however, have to upgrade my Denon receiver to another Denon receiver (AVR 4311) that was capable of driving these 4 ohm power-hungry monsters. I also have the Oppo BDP-95, and together, the systems sounds amazing. I don't regret any of it.

By the way, there are very few of these speakers left, as they have been discontinued and replaced with the LSiM line. I did a lot of research and am very happy with this set as the LSi Series is, in my opinion, one of the best speakers made for the money. I was also happy with my experience using Acoustic Sound Design. Shipping speed and packaging was excellent and the owner was very accessible by phone.

Hillbilly, I am not sure that Denon will be able to power those LSi's. I got in a debate on AVSFORUM about this. The Denon is rated as "4 ohm capable" on their website and in their manual but only with 2 channels driven (see the last few pages). All other spec's for each pair of speakers (front left + front right) are only rated to 6 ohms.

So while it may be working, you might not be hearing the "true" sound of the LSi's as they really do need a dedicated amp rated to 4 ohms to shine IMHO.

So at min if you plan to keep that Denon, be very very careful about cranking it as the 15's will make it quite toasty on top if not eventually cause a short.

Here is what the website says:

Quality Discrete Power Amplifier Section
The equal power amp design features 9 discrete power amp circuits, and each channel is rated at 140 watts (8 ohms, 20 Hz to 20 kHz, .08% THD). The amplifier section also features the ability to easily handle 4 ohm speakers.

Here is what the Owners manual states (page 142) (link)



Please note that you dont see 4 ohms at all till you look at the dynamic power section.
