CUSTOM BUILT STAND MOUNTED CABINETS FOR YOUR DIY DESIGNS & KITS ARE NOW AVAILABLE FROM FRITZSPEAKERS.COM

Interested in assembling a kit from some of the great designers here on AC or putting together your own custom designs and need some professionally handcrafted fine furniture grade quality cabinets?  My custom built loudspeaker enclosures are personally hand built by me in my shop in California and are covered in genuine fine wood veneers, then hand rubbed & oiled.

They are available in several standard finishes (natural Cherry, Oak, Walnut or Mahogany) and can be custom ordered in a wide variety of other exotic woods or finishes to match your decor.  Check out my Custom finishes page on my web site to see what else is available & contact me for pricing.

I've built loudspeaker systems & custom cabinets since 1973 and I usually have several different cabinet sizes in stock or I can build special orders in a couple of weeks.  Tell me what speaker driver components you would like to use and the front baffles will be precision cut and routed out so the drivers will be countersunk.  I recommend and will provide large flared Precision ports with a 1 inch radius.  Terminal connections can also be provided.

Pricing for my ported 2 way cabinets (in the standard veneers) for 5 or 6 inch mid/bass drivers runs about $375/pr- dimensions are 13-15H x 7-8W x 10.5D.  The 6 1/2 or 7 inch mid/bass driver cabinet size is $400/pr @ 16H x 9W x 11.5D.  The MTM size (shown with 7 inch mid/bass drivers) is about $475/pr.  22H x 9W x 13.5D   Cabinets for your 8 inch Hemp drivers are $550/pr @ 21H x 12W x 12.5D 

All of the cabinets are shipped in double walled heavy duty boxes surrounded by solid foam panels, not just in the corners.

Thanks, Fritz Heiler

Hi Fritz,

Welcome to the forum! Some nice designs and reasonable pricing, that should work out all right. 

Good luck,

Hey Fritz,

Are you in LA or the Bay area?  I see a 310 area code, but I thought you were further north 

Welcome!

Do you roundover your baffles? What about diffraction?

Do you roundover your baffles? What about diffraction?

Anand.

Rounding a baffle is not a "cure all" for diffraction issues. As a matter of experiment and testing, using ripple tank analysis, testing air motion around sharp corners and other various exercises, their is NOTHING wrong with a 90 degree corner that the human ears can detect as "oh no, the corners need rounding"

Me feels it is more of a "follow the others" reaction instead of solid data suggesting that "every loudspeaker baffle needs to have its corners rounded to be taken seriously" gesture.

Each designer chooses his or her particular layout for reasons.

This all said, I will admit that "some" loudspeaker designers are obsessed with this. I have heard some extremely good loudspeakers with 90 degree baffle corners. I think others here have as well.

Study the 1/4, 1/2, 3/4 and full wave "lengths" for 1 cycle of a given frequency against the distance from the baffle and the crossover frequencies used before assuming "Square corners=bad"

Well actually, rounding the edges actually does help, but as extensive research done by members on the old "Bass List" indicated, that you need a minimum of a three inch radius to achieve any significant benefit.

So the short answer is: Given the acoustics of your listening room and how elaborate your system is, are you willing to go all the way?

I personally wouldn't bother, other than for aesthetic reasons, but I'm not trying to please (or fool) anyone but myself.
However, YMMV.

Hey Fritz,

Welcome to the Circles. I was just thinking about you while I was listening tonight. Next time you're in the Bay Area, with a little extra time, give me a call. You'll want to stop by for a listen.

For all who haven't seen or heard Fritz's speakers; he does excellent work, both aesthetically as well as acoustically. His designs sound great, his work is solid and he's a top-notch guy to deal with!

WmR,

Thanks for your answer. And for insinuating that I am a 'follower' just like a donkey is. Did I say it is a "cure all?" I see this is your first post.  The question was actually for Mr. Fritz. Given that this was a thread that he started to promote his speaker designs, I'm going to make my answer short and encourage you to contact me off line if need be. Any and all rebuttals posted on this thread I will politely ignore. 

There are quite a few AES papers that demonstrate that baffle edges do diffract, however if they are audible is a different question. To that end most of the research is done by Earl Geddes who has shown that baffle edge diffraction is audible even at low levels. Just because the baffle edge is small, the audibility of its effect isn't also small.

Rounding over a baffle edge that is veneered is difficult. I understand. You would have to resort to solid wood or MDF that is painted. As to Mr. Fritz' speakers, they are very beautiful. Welcome to the forum.

Peace,

Anand.

WmR,

Thanks for your answer. And for insinuating that I am a 'follower' just like a donkey is. Did I say it is a "cure all?" I see this is your first post.

Hello Anand,

If you read carefully, their is a huge difference between the words "it" is more of a "follow the others" reaction instead of solid data suggesting" where the "it" refers to other speaker manufacturers, and no insinuation is aimed directly toward "you" as a person. You simply pulled that out of a hat from 'extrapolated web-read" so my apologies in advance if I failed to be clear on who or what I was speaking of.

It "is" my first post here but I have read the Audio Circles since day one, kept up with the flow of the general membership (and the ensuing teething) and have been in contact with many members, even bought many pieces of gear through the classifieds and made many friends. I have been in audio for well over 40 years in various capacities from hobbies, to tinkerer to having made my living from it in loudspeaker design and consulting.

I do feel like their was a reason you decided to take something from a point of "other speaker builders" as truefully typed and convert it into "Amand beleves WmR is pointing fingers directly at him".

I will try to be a little more clear but apologies on the first post as an act of candor is not my regular modus operandi.

No wonder hundreds of members dare not make the first post!

I am thick skinned and old enough(and almost blind, hence the typo corrections) to realise that "people like to question first posters" and find it to be a typical practice, worldwide.

Thank you for the warmest welcome. (no sarcasm intended....)

Hi Fritz,

Welcome
Congratulation and
Thank you

for what seems like great speaker / cabinet designs at reasonable prices.

I would like to listen to one of your speakers at some point

Good Luck
Sunil.

The cabinet with the 8" hemp driver above is mine. They just arrived today and I'm pleased to say they look very good! Construction is first rate and the cabinets are well braced, these little guys are very heavy. They are completely ready to go, all I have to do is connect the supplied wires and screw the drivers in. I should have everything assembled and ready to go tomorrow. It was a pleasure dealing with you Fritz 

[WmR]

Fritz,

One item that would be great and I feel a lot of people would go for would be some really nice stands that are finished, but for shipping, knocked down flat for home assembly. Are you interested in this sort of thing?
A general consensus of stand height could be established and various heights could be offered by shortening the center piece.

Just a thought..
