I’m considering the fusion over the cinema series, mainly for cost reasons. I’m not sure which speakers would fit my needs without spending more than necessary. Ideally, I’d like enough headroom to comfortably reach 95-100dB/ch (-10 to -5dB volume) with a lower mid priced receiver. I just purchased a Denon x1300w, rated at 80w/ch, but expect worst case scenario dips with multichannel peaks to around 50-65w.
My room is 20’x12’, opening to split level stair cases in the rear, and is well treated acoustically, so I don’t expect a ton of in room gain from reflections. I’m seated 10 1/2’ from the center channel, and the L/R in their current position are 11’ from the mlp. Sub is 9.5’ from the mlp, since I get the best response/boost by placing it in the right side of the front wall.
The second requirement, I’d like to be able to use an xover of 60hz, since I find this generally sounds better to me than 80hz. The fusion 8 is rated at an f3 of 65hz. I’d assume that’s full space? Since my room is 12’ wide, I get a ~47hz boost in room gain, the Klipsch R-15ms I’m using for my surrounds have an f3 of 63hz, but I get a solid f3 of 50hz in room, I’d assume I should have similar results with the fusion 8, no?
Second question, I’d like to up my LF headroom, but am not sure if adding a second Dayton sub or going for a single DIY build is a better option. Using cea 2010 burst tones and band limited pink noise, at the mlp, the Dayton sub 1500 can comfortably produce 105dB from 23hz on up. A second sub, stacked directly on top of the first sub would give me a 6dB boost, taking me from 105dB to 111dB.
For diy subs, I’ve been looking into the stereo integrity cheap 18” sub, since diysg has a prebuilt enclosure for it, it’d make assembly a lot easier, I do not have the time or tools to build an enclosure. I would likely EQ the sub via the behringer nu3000dsp or a linkwitz transform circuit to have a flat response to 20hz.
Can a single sealed one of these handle 105-110dB in my room, or would adding a second sub 1500 be a better option? At this time, I’m not looking to do dual diy subs due to cost concerns. So it’s down to one or the other.
Couple of questions on the waveguides used in the fusion/cinema speakers. What is the radiation pattern? The Klipsch I currently have are 90x90, and offer very good coverage across my entire room, even at the “mother in law” seat along the wall. I’d actually prefer a narrower vertical pattern. The Klipsch with a 90degree vertical pattern is nice because it doesn’t suffer treble roll off when standing, but at the same time, it increases floor/ceiling reflections, which are an issue in my room due to an 8’ ceiling and hardwood floor.
As for finishing the cabinets, what is the simplest way to do this? I really don’t give a poop about making them look nice, I listen to speakers and watch the tv, not the other way around. The main concern would be protecting the mdf. Would simple black gloss paint work?
Lastly, which speakers would work well for atmos heights? I’m not sure if the volt coaxial speakers or a pair of fusion 6 would work better. I realize the volts have very wide off axis dispersion, but the constant directivity of the seos horns may offer better image stability for those off axis.
I’m currently using Klipsch speakers mounted to the ceiling, vertically toed in at the mlp. They work extremely well for this because they offer uniform directivity out to 12khz +-45 degrees horizontally, and +- 30 degrees vertically. Since the coverage is 60 degrees vertical, those sitting off axis left or right experience a fairly stable height image, since the “MIL” seat is about 60 degrees off axis to the right overhead speaker, it’s about 9dB lower than the left top, providing the benefit of time intensity trading, avoiding hotspotting issues.
