Frugel-Horn Mk3 Builds & Build Questions

[planet10]

Solid wood requires the skill to work with. I know Bernie made solid FH-Lites for his daughters (i have 2 pair of µFonken in solid that was the initial plan). I will be posting those, and a set of gorgeous Garry Oak µFonkenSET up for sale soon.

Unless you're a skilled cabinet maker, this could be a daunting task.

Of course solid wood is an option if you're up to it.

Better keep to MDF and ply then. lol.

 

[planet10]

Quality ply. Avoid MDF.

I agree, made my near field sealed monitors from MDF. the build went fine and I'm very pleased with the results but painting them was a pain.

I have Baltic birch ply, both 18 and 22mm, and two thick slabs of wood (although I doubt that they should be used for baffles). I also have two 12P drivers available. Dam, I am half way to making a set of the XL models just to hear them. Probably a good combination.

I think Dave meant the effects on sound quality, which is better with ply.

Now that i have read more about the build, I may consider using some of my aged wood supply for the exterior panels. I always said that I would use it some day. It's been 17 years. Maybe now? I'm like that with some of the wood. It is beautiful, but only speaks for certain projects. The Frugel Horn has been on my list for a very long time.

Right, leaning all the time. Is it betting sound quality wise than solid wood as well.

Joan, not FHXL.

Thanks Dave, I will look into that now. Want to be pointed the right direction before I take off running.

Made the donation for the Joan plans. Will try my best to do a step by step photo shoot. What am I crazy? I will send pertinent photos as the build progresses. Besides, winter is here, and that alone will stop things for a while.

 

[Ixnay]

Got the plans for the Joan today. Even went down and had them printed up after I made some notes on them. Pretty straightforward build.

Joan?

Yah, I think that I have derailed this thread with my questions about the FH in general, leading up to this point. I will try and find the proper thread for future posts. Thanks though. This thread has really helped me to arrive for the correct build for my 12P drivers.

Start your own build thread if you like.

Many of the original recommended drivers are no longer in production. I have therefore searched for replacements and made a list, it is by no mean a compleat list. I have focused on 8Ohms drivers as that is what my OPT in my Tubelab SSE are designed for.
4-5" full range drivers

I did found two Monacor drivers that look interesting, decent SPL and relative low Qts. A little bit low on Xmas, however not as low as the Fostex drivers. Has anyone tried any of these in an FH mk3?

SPH-60X
SHP-68X/AD

I have used the Monacor SPH-165KEP as mid-base in a 3-way system with great results, that system a another kind of story with with DSP and 6-channels Amp. However was i impressed by the build quality and appearance of the Monacor drivers.

I've tried SPH-60X in FH3 and works fine. High sensitivity and good bass extension, flat to 50Hz in my room. Very nice playing rock and movies.

60X Lacks a bit in highs, SHP68X is said to have better treble (I have not tested).

All the current 4in Markaudio drivers work fine; most of the 4in Tang Band fullrange units, the FF105wk, FF125wk, FE126NV, FE103NV, FE108NS (although I wouldn't given its overall response characteristic), FE108ESigma, the Monacors referred to have always been OK, Visaton's B100 etc. A few more, but those cover a reasonable range. The alignment will differ somewhat depending on their exact spec., and you need to pick one that suits requirements of course, so I'm not saying they all will work the same way, but they do go in -FH3 was deliberately designed from the outset to accept a reasonable range of drive units so people could play as they wish.
