Default Wide Baffle Seas 3-way

Well it comes in every shape and size!

Her are mine, and I havent seen any speakers thats look the same

Its a 3-way with Seas drivers; CA26RNX, MCA15RCY and 27TFFC.
They have gone through several stages with different drivers; L26, CA18RNX & 27TDFC, and with different crossovers; passive/DIY-active hybrid, all passive and lately all active with DCX2496.

Open baffle, or is the back off to allow us a peak inside? Very pretty at any rate!

I think it is ported. there is a port below the woofer right?

Ported yes, but where's the back--that's the reason for my question.

Are wide baffles "coming back?" I did something similar to Norcad.

I like what a wide baffle does but it hasn't been easy...

I just finished these speakers last weekend and I have been listening to them every night since. I am VERY happy with the results!
I noticed from your picture that you are using the crossover component values that Martin published for the Open Baffle. In his other paper, he described the need to use a 125 hz cross over on the Eminence when in an H-frame.

My Eminence H-frame sounded terrible when I first hooked it up. Muddy midrange and some real boominess. Went back and re-read Martin's article where it says the H-frame needs to roll off at 125 Hz instead of 200 for the OB. So had to scrounge up a 125 Hz cross over. Got real close with 15 mH and 92 uf which actually sounds pretty good.

So curious if you have any of the similar issues I had.

Actually, I haven't had any problems with these. There was the burn in period, but after ~32 hours I could tell what those issues were because they were going away. I found on another forum where a guy was running his Alpha 15 straight with no lo-pass circuitry and loved it. Therefore, I didn't worry about my mistaken order from the first paper I read (discovered the H-Frame after my initial order) and thought that if I did notice something ugly, I could easily switch things since the cross-over is in the open on the back. I had two other pairs of ears over to critique and they didn't hear anything bad either. It may just be room acoustics(?), but I'm going to ride with these "as is" until I want to try something else.

To be honest, I thought we were seeing the first ported OB in history, quite an accomplishment!

I like wide baffles myself, and with the large radius roundover at the sides it must sound very nice with a smooth transition from 2pi to 4pi.

Best Regards,

I'm sorry if my speakers make you confused!

They are just some regular BR, the picture without the backplate was just so you could see how they are constructed.

The hole idea was to make the baffle wide enough so that I didnt need BSC on the mid, and round enough to minimize diffraction.

Then I coukl use a simple passive filter for the mid/tweet, active xo for the woofer, and then of course biamping.

The active xo for the woofer "meets" the baffle step, and is BSC is easily adjusted with gain on the amps.

Here are som more pictures, of the inside construction, with a longer pipe for the L26 woofer, and the woofer support,
