Clarity on Seas Thor Kit

[ErwinFlanders]

Hello everyone, first post.

I am building a new house with a semi-dedicated HT and I am trying to decide whether to build the five or more surround speakers myself or just buy some B&W CT7.3 in-cabinets (costing €1,500 each).

I came across the PMC Fact.8 tower and Fact.3 standmount. I love how they look and I like what the reviewers comment. But these are way over budget at €6,000 for a pair of the towers. The Fact.3 costs not much less.

After a search, I found the Thors on the Seas website and this lead to this thread, which I scrolled through for the last few hours! Few! I might consider the Small Thor, which is more elegant. These would even fit behind an AT screen as centre speaker, even if that means that it is close to the wall. Would the Thor perform as good as the Fact? I happen to own a pair of open baffle Jamo R909 (bought used...) which I find brilliant. Clean, open sound and deep but very tight bass. Incapable of boomy bass! The midrange is Seas, tweeter is Scanspeak Revelator. These were bought for the large open plan area in the new house.

I did audition the Klipsch in-cabinet system. OK for movie, but lacking for music: to sharp in the high frequencies. Maybe missing some mid-bass. The 3-way B&W CT7.3 sounds much better with music.

I also thought about the Jensen from Troels Gravesen (with aperiodic vents). These are 3-way and also not cheap to do.

Other info is that the room is about 5,000 cubic feet and cladded with drywall. And I am building a pair of LLT subwoofers with Maelstrom 18-inchers... Weather stopped the house build, so these will finally be assembled, time to decide about the main speakers. If I can't get better sound than the B&W's (the CM9 + CM centre 2 also considered), I won't bother. Should I bother? I have experience in cabinet making, none in electronics. The Madison kit with improved assembled X-overs seem tempting. Maybe some German or Dutch shop offers the same kits.

Any suggestion is welcome.

Hi guys,

New member here. I am wanting to build the odin mk3 with the new xover design from jimangie???

I am wanting to make a few changes:

The internal cabinet size will be the same as the original design from seas. Is it best to port the speaker or seal it like jimanjie?

I intend to make the baffle protrude 25mm out from the cabinet and have rounded edges. The flat surface of the baffle will remain the same as the original design.

Will this effect BSC? If so, what changes are necessary?

Go you mean that the baffle will extend out sideways? Ie making the baffle 11" wide instead of 9"? A sketch might help.

This will affect BSC and if the baffle just sticks out it will increase the amount of ripple.

Picture would be good.

[serioushifi]

Okay.... side view. The flat surface of the baffle remains the same, along with the width of the baffle flat surface. But 25mm on the top, bottom, and sides is added for the curve.

The drawing still leaves me not understanding what you want to do... are you adding a skin of an extra 25mm to get a bigger roundover?

I have used your picture and added what we are thinking of doing....think jamo d830 protruding baffle and curved edges.

This one may explain things a little better...
