I need advice

Go for it! This sounds like a fun project.

I would guess that finding or home brewing the right crossover will be the tricky part.

Let us know how it turns out.

I'm the negative voice....if you have extra time and money to blow on the project go for it.

I knew a man who had a hi-fi speaker company and he said that building hi-fi speakers that sounded really good is one of the hardest things he's ever done. all the numbers, theories, and computer modeling programs could point to a great design, in theory, but you could still end up with a crappy speaker. bass cabs may not be as hard to come up with a playable design, but I don't know I've never tried.

maybe consider trying to copy a successful design you like? do it for the experience of it and not under the delusion that you are gonna make a great cab for couple of hundred bucks. but who knows you might come up with something great

o.k. cab makers, am I hitting the mark here or missing the boat????

 

It's possible, but you might be wasting your time. In your profile you describe it as an "old 1x15 cab.". If it's really old, chances are that the 15 won't really be up to modern woofer duty. It will work but you won't get the really low frequency response that a modern woofer can provide.

There is a certain amount of magic in building a great sounding bass cabinet.

What you might want to do is build a mid/high enclosure for the 10 and the tweeter. See how well the three speakers sound together before you go through the expense of building a huge Triad type enclosure that you might not like.

Have you considered looking for a good used Peavey 1516 (1x15 + 2x8) or 1810/1820 (1x18 +2x10)? You might be able to get one of those for about what you'd put into building your own and it would still have resale value.

Having typed all that, I've had very satisfying results building my own cabinets.

 

I think the Triad has two separately tuned enclosures...one for the 15 and one for the 10.

 

Sure...it just seems like a lot of work to modify an existing cabinet this way. If you were starting from scratch it's easy to do what ever you want. If you're modifying an existing cabinet and dividing it into separate sub enclosures, you're reducing the volume of the woofer's enclosure which will negatively affect the low end response. I doubt that you want to lose lows while gaining mids and highs...do you?
