But Dave Wilson et al won't be losing much sleep.

You have mistaken us for people who care what Dave Wilson thinks.

Has anybody used a removable side panel? It'd be nice to be able to be able to remove a panel to adjust the stuffing but I can't think of a way to get it to seal tight without using some type of weather stripping which would look awful

We did that on at least one of the early prototypes to validate calculations of fill levels, and yes the weatherstripping and numerous screws on removable side panel wasn't a pretty combination, but once "dialed in" I permanently glued it up, and with a little bondo and veneer, you'd never know.

What a couple of builders have done is fabricated with the top panel removable, which allows access to both sections of fold - albeit rather tight for the rear "upper" closed portion. Would still require gasketing to seal, but a much smaller piece to be patched up later.

Whichever method you try, I'd recommend some type of open mesh screening glued or stapled across the line, approx half way down the front expanding section to prevent any fill below the driver from shifting out of place.

Blu-Tak or similar should do the job, if it's continuous.

The tulle I bought from the local dressmakers worked very well in the Super Pencils.

FWIW, the historical favorite is the cheesecloth found at paint suppliers, hardware and most 'big box' stores.

[chrisb]

fair enough - the wire mesh scree was just something that was lying around the shop

 

[GM]

Yeah, until special pet screen came along, we normally used scraps from damaged screen doors, a plentiful commodity in the Deep South before A/C and pets confined in the home became the norm.

Any frugal horn owners in Atlanta

Hi Guys,

I have been reading about the frugal horn and have only read good things. i am very curious to hear on how they sound. I would like to build one but since i already have decent pair of speakers i want to make sure that its worth the investment. I would greatly appreciate if any one in and around Atlanta would be willing to let me listen to theirs.

Thanks

If you are ever in the NYC area you can come hear mine.

 

[Poultrygeist]

I'm 3.5 hours away in Columbia, SC but that's probably too far.

 

[katariat]

thanks guys, hopefully i will find some one close. In the near future if i am heading over in those directions, i will definitely ping one of you. Appreciate it a lot. thanks

I know this isn't most people's cup of tea, but does anyone use these for metal? I'm thinking of building a pair, but I have also heard that single, small full range drivers don't generally handle metal well. Was gonna go with the CHP 70

 

[chrisb]

If you can possibly afford the physical footprint, I'd suggest that the FHXL an A10.3 would be a better bet for metal - but if constrained in space / budget, the CHN70 would be worth a try.

 

[nbriles2000]

Unfortunately I have neither the space nor the money for that build! This will be paired with a Magnavox 9304, yaqin ms12b and an AR XA. I'm just hoping this set up will be dynamic enough to keep up with much more energetic music

 

[chrisb]

Not being familiar with all genres of "metal" - brief exposure to Metallica / Tool during my son's late teens was about it - I think either the CHN70 or A7P's upper mids and top end might better serve the program material - the current CHP I find a bit soft / dry above around 3-5? K .

 

[zman01]

nbriles2000, from my experience single full-range/wideband driver speakers don't do metal very well. At lower SPL maybe ok, but not a very dynamic sound. Cone size matters and the speaker needs to deliver in the 60-200 Hz range. FR units can go lower in bass, but typically don't deliver the slam or "energy". My guess is that a four driver/cabinet Microtowers type of speaker with CHN-70 might be able to do a better job, but this is untested. 2 way systems for metal are smaller, cheaper, simpler to build.

 

[nbriles2000]

This seems relatively consistent with some of the other things I've seen.
Can you offer any alternative suggestions?

 

[chrisb]

There are a few stock questions I like to pose in such situations, a couple of of which you've already answered:

1) Venue / application - i.e. room size, and for music only, or combined with HT / movie playback
2) Type of program material / listening levels
3) Available power


What are the characteristics of systems have you heard perform this type of material to your satisfaction?

While a "FAST" type 2 way might be more than capable,, it could well be that a single driver FR system of any type wouldn't quite make it sing for you.
