Hello NBC,
If you have the space, and the sense of humor, go with a large pair of SEALED enclosures.
If done right, it will change your life.
Regarding the Northcreek Audio version of the 1808 : According to some research I did a while ago, ...

This weekend I am starting to draw the sketch and the preliminary building plan for my midbass horns. I initially thought to recruit somebody who have done it to help me with plan but after consulting with a few people I feel confident that I hav...

Well, it looks like this beautiful speaker did not get the traction that it deserved. Musique Concrete is no more BUT Marco Henry is offering most of what the Grande Castine was on line for only 14000 Euros. Check this out:https://www.kornhent.bzhThe...

Romy, as you know by now, most small generators are toys, really not suitable for our purposes. I have no idea where or how you found the perfect old small generator, but starting with what you have, if you can get all the wiring right, you just mig...

HI Romy, thanks for the thoughtful reply. The electricity comment is interesting as today I put on some jazz music and the HF is very snappy, excellent! I feel like posting on AA to ask people's opinons if it's the electricity or if my concrete...

romy, you said, you would place a 60hz midbass on the side, is this still your opinion? of, course i found no other solution in my small room. will do it the way you suggested, 60-300, 300-1000(thinking about gpa 288h(s2 is too expensive for me), may...

No doubt you've given some thought to the relatively large load you will be placing on your new floor joists. From pictures you have shown on this site, and guessing at the weight of all that equipment in it's racks, I figured your Back Bay set-up m...

Gut-wrenching story, Romy. I will seek out the recording. I well remember both that invasion and also R playing when the concrete part of the Berlin wall came down.I wonder how US artists abroad felt as our country invaded Iraq, smas...

Sarurntube, I am quite curious about the mysterious tapped horns these days. What are the physical dimensions and power requirements of your tapped horns? Are they 1/4 or 1/8 wave horns? Do you use a FR amp or a sub-only amp to drive them? Do you...

I find this solution of inlaying a solid (concrete?) plinth/platform in the flooring to support the speakers very elegant and it should be very efficient at eliminating floor resonances:You could also make a similar structure to support your equipmen...

Jessie, I should say that the LF horn appears to me - a horn dropout - to be sort of the Philosopher's Stone of the True Horn Believers (THB). Unimaginable amounts of time and effort have gone into it, apparently with the most likely resul...

Sure, contemporary polymer concrete can be made suitable for speaker enclosures or horns. Its biggest sonic benefit is that the material itself is fairly non-resonant. It's just a bitch for a DIYer to make one after another while experimenting with s...

(feel free to re/move this post to the electricity thread)As the power supply I'd regard everything from the power generator in the power plant down to the actual load.Why the power transformer should be the cutting line? I do hear your voice clearly...

One easy way around any zoning issues with an added on room is to find a house with a large garage, knock down the garage and build the new space on the existing concrete pad. That way you won't have to worry about easements and how close you are to ...

N-set, of course the finish flooring is supported by some sort of structural "members". These MIGHT be reinforced concrete, and so MIGHT be quite strong, depending on the whims of the builders at the time of construction, and considering any loss of...

Once again, there is nothing specific in this post just some further thinking on the subject, as I keep discovering new idea.
A couple weeks back I was looking at a house that gave in inspiration to think about it. The house was 3 bedrooms Cal...

If time (Endo-san and mine...) will allow, I should also visit Endo Labs of ALE fame... sure I'll have a listen to a 4 ways system in Tokyo area with bass driver and concrete horn.Re. "tilted high frequencies"... no, Roman, it's not me experiencing s...

As a builder I can pre-warn you that this could be a fairly complex and very expensive proposition if done in cast concrete. For that matter excavation, per se, is expensive, and municipalities differ about what you can...

Thinking of the transition from round to triangular, I go back to Jessie's fibrated "plaster" for the round profile section. To make the transition, make the narrow end of the triangle "too long", and somewhat larger inside than need be, to serve as ...

Romy, it is not difficult to find tough plastic and transite pipe in many sizes, including diameters large enough to house your entire woofer, and many types have a range of manufacturered fittings, including sleeves and reducers, that you might adap...

Paul, I thought about the wall mount, but eventually decided to go with a more universal, pref. end of life solution, I could place anywhere. I've never had a dedidcated rack, a time to have one.The result is a slate-on-steel-frame 500kg mastodont, I...

Yes, in my esperience this is most dangerous because it can end up sounding sort of good.
