Re: Ultimate Subwoofer

This sub definitely deserves more attention, performance is amazing, its a fun build and can be had at a fairly low cost. I suspect its size is a deal breaker for most.


Want to send Mark a big thank you for this design and give an example of how to 'hide' a sub this big in plain sight.

Re: Ultimate Subwoofer

Nice work!

I have done this type of design in the past. It really looks like a credenza.

Even makes an old cabinetmaker proud!

As for performance.

It is a fun ride.

And it never stops. The performance level is truly unobtainable with just about anything else.

So you get a trade. You do have a big box.

With seriously big sound.

And you can drive it with amazingly little power.

You make me very happy.

A few guys have done this , and created a very professional looking cabinet.

What did you use to construct it?

Re: Ultimate Subwoofer

Awesome build! How can you keep anything on the walls? I built a few subs, and as you say, size and where to put them can be an issue. My (2) are the Decware "House-Wrecker", and Bill Fitzmaurice Tuba HT Horn Sub. They both will split atoms if you push them. I use the House-Wrecker in my HT set up, and the wife insisted that the BF Horn get regulated to the Garage (its Big @ 30x36x36). Hard to beat a horn loaded sub, as they are efficient and pound out the bass.

Re: Ultimate Subwoofer

Nice build ChoEnd!

I got the plan myself and I can't wait to build mine. I want to turn mine in a sort of cabinet too so it look nice. Doing this will allow me to be within the WAF while using a crazy large subwoofer. I'm not sure what I will build but I plan to use Red Oak. Since I don't have the best wood worker skill in the world I will not all out like you but I wan't to make something nice!

I just finished to built a Tuba HT for my brother in law and even the Tuba with 25 watt can pound quite hard. I can't imagine this subwoofer!

Re: Ultimate Subwoofer

Mark,
The speaker was built using OSB, it just seemed wrong using OSB for a speaker but for the $ I figured if was unhappy I'd redo it..no regrets.
The top is cherry and front cherry frames w/veneered curly maple panels. Each attached with a few blobs of silicone. This came in handy when I burnt up the original driver. I used a forstner bit to cut reliefs for all the driver cover screw heads.

hesster,
An oddity is nothing on top of the speaker seems to be impacted but the rest of the house is in full motion, pictures, mirrors kick knacks all rattle and complain.

steeve-0,
Its a really fun build just keep critical horn path dimensions to plan and square, PL adhesive will forgive the rest. If you don't have much wood working equipment a track saw or hardboard jig circular saw will break down 4'x8' sheets cut laying on pink board insulation(google) will get you through. Use screws instead of expensive clamps. As for WAF, who know what your missus will accept but old shutters/cabinet doors or even windows are possibilities to skin cabinet.

Re: Ultimate Subwoofer

OSB rules man!

When you actually work wit it a lot, (as I do in making prototypes) you find that it is really a great almost ideal material.

You made a beautiful cabinet.

And you have the same experience that I do. Very little shake rattle and roll on the box.

Not so for the rest of the place!

I have one TRIO12 kicking around if anyone wants one.

Re: Ultimate Subwoofer

Mark, could I please get the information on this.
I was fascinated by this a few years ago and actually contacted Creative about shipping, but delayed and it taken off their list.
I discovered this thread and figure if I'm going to build a front loaded horn it might as well be a whopper.
thanks
Paul

It's a set of plans, very detailed with plenty of photos. My set is a couple years old. I'm sure there have been improvements to them since then.

PM Mark directly for more information. He's usually pretty quick getting back to people and, for me at least, dealing with him was a pleasure.
