You know what...I just might. I have a Sony CD/MD player that came in the Fairlady...the same place I yanked the Bose from. If the Sony happens to not work I'll give it a good toasting....

Its the best example I can recall, of marketing genius.
Bose stuff is absolute trash, but at one time (and maybe still) were the number 1 speaker company in the world.
Fram filters also come to mind.

A Fram filter probably sounds better than a Bose speaker.

We ussually don't agree on matters of audio, but this time we're on the same page. :-P

Meh...we agree...we just have different ways of getting to that Nirvana.








like subwoofers for instance

Thats one of the good things about building speakers as a hobby.
Theres 100 different ways to do it, and they're all right... or wrong.
You don't still believe that you can build an enclosure without some kind of resistive, or reactive lining, do you :screwball:

Well I have to confess that the best sounding enclosures I ever made had a 1/4" liner of cork on the inside of them. Some car audio enclosures got a layer of dynamat in them. Ported enclosures rarely get anything in them at all though...

I dunno about that. I've done with and without comparisons and although there is a change in the sound it seems like it was more from the change in tunning frequency (because I could mimic the change in sound by swapping ports) than from any resonances that have been absorbed. Now to add to that while I don't load up on the fiberglass filling I do spray a sound deadener on the walls of the enclosures in almost every case. The enclosures are also made very stiff (with a good amount of bracing on large enclosures) to help eliminate any mechanical resonance/colouring of the sound.

Direct radiators still suffer severely from harmonics. They have always sounded muddy to me.

I built horn with one of those 8" MCM speakers and I am very impressed with the accuracy and efficiency of the bass that I get. My next project will be a horn with a much longer horn section and two 8's for home theater and stereo.

I built a sealed box line array a while back from 8 - 4x10 car speakers and 21 - 3/4" onkyo tweeters. I want to build them into a corner loaded transmission line about 6-7 feet tall.

I have never gone for conventional boxes, it seems like everyone has a sealed, ported, or band pass box and none of them ever really sounded all that great to me (unless you are a millionaire and can afford it).

Has anyone ever experimented with electrostatics?

I've heard a few and was impressed by how they sounded...but could never afford one let alone 5 for the home theater.

I always said I would get into electrostats when I could afford to play with them.
IMO, a hybrid electrostat like Martin Logans is the best way to go.
Even better would be a TL/electrostat hybrid.
Now that I can afford it, I don't have the time.
Not only that, but I don't know if materials are as easily available to the hobbiest as they once were.
Aside from subwoofers, I don't think there is near as much interest in the hobby as there once was.
OTOH, forums have made magazines like speaker builder obsolete, so there is still lots of good info out there, and its easy to find.
The transmission line is probably my favourite, and I've buuilt lots of them. I would like to build a line array, but haven't yet found the drivers that both look good, and are priced right.
Right now I'm fiddling with these
http://www.creativesound.ca/details.php?model=WR125S
Bought them last year, and didn't have the time to do anything with them.

From what I can gather ESL's are really cheap to build as long as it is a hybrid. Almost everything can be had at Mcmasters. There are quite a few cost effective ways to run them also from what I can gather.

I have alot of those old magazines and books on the topic. Unfortunately my brother's dog chewed up my nearly complete set of Speaker Builder while I was away.

I bought the ELS cookbook awhile back and got hooked.

I have a couple of pioneer 4 1/2" speakers that I want to put into a TL just to see how good you can make them sound. I've heard good things about TL's, just never built one.

The line array is a great idea. From what I have heard is that if you use a cheap speaker with kind of crappy frequency response, that it will improve greatly when grouped in an array. Another thing is to be careful with the upper frequencies, use very small tweeters and group them as tight as possible.

A single driver type in an array will cause a great deal of comb filtering in the upper frequencies. I am currently having this problem with my 4x10's because I turn the top two sideways from the rest to make room for the tweeters. Now the voice coils are too far apart on the top two speakers from the rest of the group and have a very peaky mid range response. For lack of better words, it's very nasty to hear certain frequencies on the array.

Mike I heard a line array with those drivers and it was very impressive given their size. I did a pair of wild subs that even you would be impressed by ;).

A line array with the WR's?
That would get expensive.
MP, I wouldn't bother using those pioneers for a TL.
Wait until you have something with a low enough Fs, <40 hz, mid to high Q, roughly between .35, and .5, and good Vas
Then you have some bass potential to work with.
The thing about building a TL, is that it tuning, tuning, and more tuning.
But when you get it to work, its well worth it.
As nice as it is to have all this info at your fingetips, I miss speaker builder magazine :cry:

I have a whole lot pf books on design, but the mags are the best if you close at them.

Sorry I was mistaken...it was a Tangband 2" driver from Parts Express. Jumped the gun a little when I saw the driver as they look similar. I think there is a project that uses them and thats where this guy got them from.

I'd love to tackle a Transmission line project someday as its something I haven't built yet. I've done a whole lot of neat speaker designs but for whatever reason never did a TL. I think a simple 2 way for the home theater mains and rears could have some serious potential.

Mike, do you have some pics of your TL's? I would love to see.

I don't, but I'll take a few and post them.

The tangband stuff is pretty cool, but I think 2" is still a little small.
Parts express can be great for projects like that, with their clearance specials, and buyouts.

Oh yeah they were tiny...but paired with a good subwoofer they covered a suprisingly broad spectrum.
