That didn't look good, different colors of the wood :S
But yes it's a good idea, but how to make the top-part sit steady on the sub-part?

These were among a series of prototypes built months or possible years apart, ( IIRC, the upper Fostex boxes were clear coat lacquered while the lower cabinets are still raw) easily veneered or painted in matching or complementary finishes in an afternoon or so. The vertical strip on the bass enclosures was to correct for a cutting error on chamfered edges.

I think Dave's point was to consider the advantages of incremental steps for a beginner with an apparently limited budget, as well as existing gear that could be used to advantage.

While "just" and EL or CHR 70 will certainly lack massive weight and extension in the lowest 2 octaves, particularly for full-impact home theater or party level club music, don't underestimate their capacity from midbass ( 100/120 so ) on up, With proper relief of even a lower quality woofer (likely independently filtered & powered), either of these drivers can raise eyebrows.


As for stability of the upper enclosure - either metal straps ("mending plates") or Blu-tak (a staple of any audio DIYer's kit) should suffice to affix to the lower enclosure.

Ahh okay.

Yes, making it in steps is almost always a good idea. Like starting with 2.0, then 5.0, then 5.1 then 7.1 and so on.

I'll probably go with EL70 since i suppose it's a little better than CHR-70 since it costs a little more.
But, what about 80-100hz then?
And i like to play relatively loud. With windows and all doors shut you can hear it on the street 10m from my house (my room is close to the street). You can't hear it loud and clear, but you can hear what i am listening to.

Edit: Did you mean this? http://www.joma.se/viewimg.php?image...E5lband-20.jpg
And with Blue-Tack, wont it leave a little colored spot after it on the surface?

It is the concept you want, not the specific execution... althou these would house a Trio8 each (they could be a bit smaller actually) or any number of other midbasses. As built they aren't really material efficient.

Some guys on a swedish forum told me to step away from Trio8 in a 2-way construction. Are they right?

When you say 2-way, most will think 2-4kHz XO. Trio8 certainly not good for that. But XO at 100-200 Hz it will work great.

Just tell them your tweeter can be made to go down to <100 Hz. Then watch for the incredulous faces

't'aint necessarily so,

don't confuse price and quality


that's plumbing strap, more like the attached
