Speaker Design Critique

[ryoung]

Would using the 2 mids in the bottom section sealed from each other or sharing the same space be better?

I'd use the same space.

With one woofer on each side, one will be playing into the side walls, unless the room is very big ... dont you think that could cause problems ?

Another thing ... with a slim front fore a 6", which I suppose is the goal with this design, there is little room fore the sub drivers to be coupled together, magnet to magnet

Have you thought about building it with a Rythmik Servo-subkit ? ... should be quite good

tinitus, with 2 seas H1305's in the bottom there is exactly 1.04" between the two magnet assemblies

depends how low you XO.

The Omega synbol is the trademark of a commercial vendor...

[ryoung]

Yea, everything is trademarked these days... I'm just playing around with some designs for the front

 

[ryoung]

this may be a bit better

 

[tinitus]

I dont understand where you are going ... are you making a 4way now ?

 

[ryoung]

Right now I'm not set on 2-way 3-way or 4-way.

My goals for this project are to have a good set of speakers for music as well as home theater without the need for an additional subwoofer

What's the deal with the sloped back and the... I don't even know what the proper words are. The cut where the width of the cabinets decrease - why?

 

[ryoung]

Cosmetic

 

[454Casull]

If you need to minimize the width of the cabinet (not necessary unless for WAF, IMO), I would suggest a 3.5/4-way in the way of TMWW or TMWWS (S for side-firing sub).

I'm thinking Seas 27TBFCG crossed to a Dayton RS52AN-8 crossed to two Dayton DA175-8 (or better, depending on budget). Also, if you watch a lot of movies, you'll probably want a sub in there.

Crossing around 2kHz and 800Hz will keep off-axis response fairly flat and avoid trouble zones wrt harmonic distortion, I should think.

 

[tinitus]

3.5 way makes no sense

And really, whats the point of making 1.class enclosures and then mount sub drivers in them to really excite some profound ressonance

 

[ryoung]

So would I be better making the enclosure wider and using a forward firing subwoofer?

 

[tinitus]

You will probably get the best result with a "standard" 3way and a Linkwitz Gainer on the woofers ... but it really depends on your goal and whether you can design and measure a crossover

But its trouble getting regular woofers with enough Xmax ... maybe you will have more luck with a 2.5way with sub

 

[tinitus]

Zaph has a small and cheap MTM which you may be able to use in your own design with side subs

It may be a good idea to make your design modular

Hi,
I liked what you had back in post #5. Simple, good looking.
If you take much more advice here, you'll end up with the same-old same-old that there's a billion of here - the boring rectangular MTM.
My suggestion is to stay with it three-way with the midrange and tweeter in the top unit. Then as mentioned before, use two shallow woofers push-push near the bottom of the bass unit. fire your port out the back.

What are you building your models in?
