Bloated speakers/weight wise

[QUOTE]..."The problem involves lowering the sonic contribution of the speaker cabinet, which at some frequencies can amount to 40% of the overall sound emitted by the speaker"...[END QUOTE]

Try this some time...Next time your listening to music, press one ear tightly to the cabinet and plug the other ear. When I did this, what I heard was not good. If I could magically turn of the cabinet, I wonder how much better it would sound, you know, like an A, B comparison.

I would like to shear one more thing. Unlike most setups, the Walsh sound much better to me on the long. The room is 24'x 14.5', ceiling height is 8.5' and the speakers are 12' apart (center to center). If I sit center stage, I am 12' from each speaker, (great sound stage). Now if I listen 5' off center to my right, the same sound stage remains, but shifts to the lift.

Now here's the real "kicker"; I have another pr. of Walsh, the smallest ones they make; I think there call the 'mini shorts', they are used as the rears. To explain what the rear speaker do, there are two links below that explain this.

Here is my personal experience of the difference the rear speaker make...Without the rears, there is a great sound stage in front of me. With the rear speakers, there is a great sound stage in front of me, PLUS the room is FILLED with music and I am not aware of the rear speakers playing, but when I shut them off, all the music shifts in front of me; there is overwhelming difference and this is done with no extra electronics; one, two ch. amp. is all that's needed.

Sorry about talking so much about my system, but I wanted to shear this with with all that may read this.

Here are the two links that explain this.

Macrojack, How do you know that your cabinet does not produce any sound? How did you test for this?

After reading some of this thread I did a little experimenting. First I tried to feel vibration on the cabinet with my fingers and could not feel any, so I tried my lips and then my check (the one on my face), still nothing. Next I held a glass up against the cabinet, (you know, like holding a glass up to a door as to hear what is being said on the other side of the closed door), then I could hear something coming through the cabinet. But what worked even better is just to press your ear firmly up against the cabinet, by doing this I could hear even more. Don't forget to plug the other ear and cut the volume off on the other speaker.

Have you tried that? If not, how did you test?

My last post nor does the link I posted explain how to wire the rear speakers, so here is how it's done.

Leave the front speakers wired as they are now. Now run another wire from the 'positive' on left ch. front speaker too the 'positive' on the left ch. rear speaker. Do the same with another wire with right ch. front and rear speakers. Now run a wire from 'negative' too 'negative' on the two rear speakers. YOUR DONE.

I do not understand why it works the way it does, but it works. In the first link I posted, they call this Hafler Stereo.

I am not sure the second link I posted talks about this. To much to read. I did not go through it.

Sorry Bart, got carried away, did mean to do that. Funny how one thing leads to another.

Zaikesman, what you say about horn speakers makes to me in the same way it does to you and I cannot enlighten you on why efficiency should make any difference other then horns.

I tried to feel vibration again, this time at a louder level and had no trouble feeling it with my hand flat on the cabinet.

I have the larger Walsh Ohms (the older trapezoid style). The cabinets have generous cross bracing and some lead on the all 4 sides but not that much. Now what is different with these speakers is that the driver is not 'in' the cabinet, the driver is outside and on top of the cabinet facing down. This eliminates all chance of rocking the cabinets, but I don't know if this would also reduce cabinet talk. One of the things these speakers are known for, is there beep base (25hz) with authority. There is a port on the bottom of the cabinet.

I don't think I can really hear 25hz, I have this one cd that really goes low with electronic sound, but I don't no how low; I don't so much really hear it all that much but I can feel it and so does the floor. My ears are 63 years old and I know they don't perform like when they were 16.

(I also should mention though, that I'm one of those who feel listening at unnaturally low levels, while sometimes unavoidable, does constitute its own form of distortion that renders reproduction less lifelike. Of course the same thing goes for listening too loud as well.)

I would think most speakers are designed for accuracy at the realistic listening volume. I remember talking to John at Ohm Acoustics many years ago about the different models he had back then and he said that he has this particular model that sounded really good a low listening volume. He also said that he did not understand why this was so, he not intentionally designed it to do that, but it also sounded good at realistic levels. I do not remember the model, but it was not a Walsh and I doubt if it's being made at this time.

speakers that aren't large, driven by amps that aren't high-powered -- both of which are common in this hobby -- can't really get that done for the most part.

I once owned full range electrostatics's (acoustat 2+2's), I did not keep them long. Did not like that small sweet spot and missed the dynamics. So I got my first pr. of Ohms, they are very easy to live with cause to me they sound like a hybrid, near electrostatic sounding with dynamics plus a very large listening area. I am a Ohm fan now.

Now to the quote above. I came across this particular Blue Circles amp. review, and after reading it I called John at Ohm's again and flat out asked him what amp. he would recommend for the Walsh's I have to get the most out of them. Now mind you; I have been using a ss 200 wpc at 8 ohms, 375 at 4 ohms and when I played music at higher volumes, the sound became fatiguing and earitating so I thought the amp. may be clipping. Well anyway John recommended the Sunfire Signature, and he said, make sure it's the Signature. What a difference this kind of power makes on these speakers. There just a clear and keep there composure at higher very high volumes, so high I can't here myself take (like I take to someone in a quiet room).
It was reading this review that prompted me to call John.
