I wanted to post a little info on the project I just drew up and am about to start.

The enclosures will be twin 10 cu. ft. net (294 l) with a 6 inch port tuned to 16 hz.Exterior dimensions are 32x30x23.75 The drivers will be the AV15X . I will be powering each with an EP2500 and my MIC2200 will be on high-pass duty.

John will hopefully have my first driver shipped out this week and I will be ordering the second pretty soon .

This is my first ported design from scratch so I welcome corrective criticism from you guys if you see something that should be addressed , ( other than my lack of google sketchup skills lol ).

I am posting a couple of graphs below. The vent velocity is pretty high below tuning but hopefully wont be an issue with the use of the high-pass.

How far is that port opening to that back wall? The reason I ask is it really shouldn't be any closer than 6". Also, are you planing some kind of port flare?

 

[Rightbrained]

The port is just over 6 inches away from the back wall. The front baffle will incorporate the port flare and I havent drawn it up yet.

One EP2500 would easily power them both. You have a pair of EP2500's already?

 

[Rightbrained]

Yes , I have a pair . You are correct ,I ran the plot with the EP2500 in stereo and I should have plenty of headroom .

Hmmmm , seems I need another project to put the remaining EP2500 to use.

Looks very nice! What are your plans for finishing the cabinets? Are you using MDF?


Jason

 

[Rightbrained]

I am thinking of using mdf and then using laminate flooring to cover it like I did when I built Dan's Easy Button design.

 

[JasonColeman]

I haven't seen pics, but how do you finish the corners? How do you keep the laminate flooring from rattling against the cabinet?


Thanks,


Jason

 

[Rightbrained]

The corners are mitered and the laminate has the backing removed and then it is secured with contact cement. Take my word for it , the laminate is not going to rattle.

The baffle on this particular box is glued up 3/4 red oak.

 

[JasonColeman]

Nice. I was envisioning running the laminate boards end-to-end at the corners and wondering how you'd handle that. On the top corners, front to back, are those boards bevel-cut against each other? With a laminate, that must be a sharp corner due to the thinness of the lam?


Jason

 

[Rightbrained]

The corners are mitered (beveled) and then I used the iron on edgebanding to cover the cuts.

 

[JasonColeman]

Any chance you'd post an up-close pic of that?

My drivers arrived today and they look awesome. Nice work John !

I have them mounted in the enclosures and hope to get some REW graphs posted this weekend.

 

[Ricci]

Looks nice. What do you think about the drivers so far? post up a review and some REW responses when you get things dialed in.

 

[Rightbrained]

Ricci ,

The build quality on these drivers is superb. I am also quite impressed with the sound although I only had a short time to run WoTW at modest volumes last night. I will begin getting these set up tonight and will continue with modest playback levels . This weekend I plan on doing the REW sweeps and testing different placement options.

 

[John_E_Janowitz]

Hi Thomas, Any more info yet? I've had a few people asking about your results.

Hey John ,

I have been really busy of late but I will try my best to get some REW graphs posted here and on the AE forums.

I am really liking these drivers. They have fantastic SQ and are seriously clean.

Very nice man!

Here is the initial REW graph with no eq and no smoothing.
