DIY SG 893 Cohesive vs Cinema 8?

May just try my hand at one of these two speakers to compare to my Catalyst 8Cs. I have a Sunfire 200 watt amp that I'm only using to power my rears. Looks like the sensitivity on the 893 is of course much lower than the Cinema 8s. Anything taller doesn't fit the cabinet they'll go in.

Curious with the amp in question if it would still provide enough power to effortlessly dive the 893s in a huge room 18x26x10 open to a kitchen that is about the same volume.

Would imagine SQ is better on the 893.

Are there prebuilt x-overs for the 893 btw?

The 893 is a pretty conservative 93db. But yes the Fusion 8 definitely has a sensitivity advantage with the woofers it uses. Do you need a center channel?

Your Sunfire amp will barely wake up to drive either of those speakers to fairly stupid levels. I'm very familiar with Sunfire amps, and it pairs with just about any of the DIYSoundGroup kits and will drive them to stupid levels. The signal will clip, the drivers will give up, or you will be driven out of the room long before the Sunfire would reach its limit.

So you're saying I need more power?

If you don't need a center I'd be tempted to go with the Fusion 8 for the higher sensitivity. And that's coming from the guy who designed the 893. I also know you run your subs up to 150Hz or something like that so no need for the additional bass on the 893. The 893 is a 3 way which may have some advantages but with an 8" speaker a 2 way should handle things just fine. I haven't heard the Fusion 8 so I'm being somewhat theoretical in my opinion. Tough call actually consider you probably don't need the added sensitivity.
