Watched Battle: LA last night. Movie - ehh, give it a C. Good efx, poor editing and script.
Crazy low bass extension in the movie added to the alien-esqu weapon technology. Funny thing is, no one realized the subwoofer was off. A testament to the LSi15 and its superior versatility and extension.Do you hear that buzzing noise? -
Can I replace the 8" sub with a momo 8" ? I have two at the house collecting dust for the past 4 years. I think they are single voice coil.I would never recommend the LSi25 since it doesn't do anything significantly better than the LSi15. The subwoofer was an afterthought and compromised way too much to retain the form factor of the LSi lineup.
The LSi15 doesn't require anymore power from your amplifier due to driving an additional 10" woofer. It's a 4ohm loudspeaker which is usually a tough load for most gear and the difference between adding a single driver at that point is negligible. You need a solid amplifier section in your AVR, or a stand-alone unit. You're going to be using a subwoofer and cutting the L&R mains anyways for a HT enviroment....so the power requirements again, level out.
A bonus is that you may also upgrade the woofer in these(LSi15) with a Polk dB Series subwoofer driver and really tighten them up. It's just a better speaker and it even offers an easy, cheap upgrade to boot.
I suggest you go with your gut and do the LSi15 w/ a crazy subwoofer.
