Looking for a small decent cabinet and driver

[chrisb]

Expanded BH MKI drawing can be found in the last couple of pages of the original FrugelHorn planset

http://p10hifi.net/FH/download/Fruge...aps-130307.pdf

This design has been superceded by the FH3, and the above plans are a bit tricky to find.

During the development stages of the FH design we built at least one pair of the BH MKI as drawn above, and it worked well enough.

There are a couple of other compact BLH designs to consider for the FE126E:
the very successful FH3 - which is a rear mouth, so needs at least some "breathing room", if not corners for boundary loading; and Madisound's BK12 - front mouth, more compact and compromised in bass extension than the FH3.

I've built all 4 of the above mentioned designs for the FE126, and provided you have the appropriate floorspace, would unreservedly recommend the FH3.

Chrisb thankyou for your advice!
Another question, the results that are obtained with this cabinet:

are not so good than the horn type, is it correct?
I'm also consider the enclosure of Mister Takenaka
Detailed information on Helix-AG180Z
but it seems that nobody has tried then.
In your old post of this thredIt should also work well enough in a FAST or MJK style OB system.

Can you explain these acronyms?
Thanks again.

Fast means Fullrange Aided Subwoofer Technique or something similar
( fullrange and subwoofer together ? )
Just search the forum
Search also for M.J.King .... OB means Open Baffle , so no box....and it is related frequently to dipole type emission .

well the acronyms have been elaborated upon, so I'll reserve my comment to the first enclosure mentioned : as noted on the drawing, this was one of numerous designs that erupted from a group design project intended to develop a DIY "reference" speaker (as in the sense of "frame of reference" - if affordable and easy enough to build, then enough folks would do so as to have a benchmark for comparison to other designs)

If I recall correctly, I built several different enclosures from this exercise for the FE127E, one pair of which resided in my mom's living room until just a couple of weeks ago, when it was time to celebrate a milestone birthday (80) with an updated pair. .

In any case, the FE126E is a great driver for what it is - certainly an excellent candidate for 2-ways such as a FAST &/or OB , , and they really shine in a range of BLH such as those mentioned above, but don't expect much output from a single below the mid 100Hz range in smaller boxes of any alignment.

Actually, this can be used to advantage in compact multi-channel HT systems.
