Another issue that is often overlooked, with woofers that large, is their dynamics. Especially with vintages speakers as these are, they have "vintage" materials. They typically do not have the rigidity of modern materials, or their light weight. To control them effectively, requires a lot of dynamic power from the amplifiers. This is one of the reasons speaker manufacturers have moved to smaller woofers as they produce, by their very design, tighter, cleaner bass.

I have just replaced these woofers with new ones and they sound a lot better than my old ones. But, my listening space is quite small, so both my speakers are in corners. They are about 1.5 feet from the side walls and about 2 feet from the back wall. The center of my speakers are about 8' apart and I sit about 8' back from them. So, my triangle is 8'. These speakers are 20" deep, 28" wide and 4' tall. The good thing is I don't have a wall behind my sitting area for about 40'. These woofers will blow me out of the room so hearing them is definitely not a problem.

What brand and model are the speakers?

Please Help!!! Info On Grand Marshal Speakers!!!
Very cool. their rarity and the brands rarity hampers the value. But, enough people love Frazier that they would be quickly snatched up! So yeah, I think the only way to ever know their value would be to clean them up and lens them nicely and put them up on the 'Bay with a really sexy...

Something wrong with your speakers I suspect.

Marshall makes PA amps, and those look like they might be PA drivers. I wonder if this was a factory effort to build a consumer speaker based on some of their pro drivers? Just a thought. bs That's a good guess, as that 8" or 10" mid has a basket designed to stack multiples next to...

When I do any system changes the track used to make sure everything is wired correctly is shown below. Turn up the volume. If correct, the dog barking will be to your far right and the radio playing will be to your far left. If not, those sounds will come from between the speakers.
Maybe something’s up in the tweeters , midrange or crossovers that where you usually hear the separation no in the woofers !
I think I have found the problem. My McIntosh MCD 7007 CD player is starting to act up. Poor old girl has a few years on her. I was listening to my two turntables yesterday and I noticed they sounded a lot better than my CD player. I found out that my woofers were not happy with it and they were starting to make a hissing noise. So, I grabbed my Rega Apollo and it really made a difference. The Rega has always seemed a bit brighter, but I can always adjust that. Looks like it's time to rebuild my poor old McIntosh.
That’s not entirely accurate.Another issue that is often overlooked, with woofers that large, is their dynamics. Especially with vintages speakers as these are, they have "vintage" materials.

This is one of the reasons speaker manufacturers have moved to smaller woofers as they produce, by their very design, tighter, cleaner bass.
Large vintage woofers, often made from materials like treated paper, can deliver dynamic, well-controlled bass when designed with a balanced motor structure and appropriate mass. Modern materials like carbon fiber and smaller woofers offer certain benefits -such as compactness and higher rigidity -but these qualities do not inherently improve bass quality. Bass response quality is shaped more by enclosure design, and motor efficiency, than by woofer size or material alone. Both large and small woofers, when properly designed, can produce accurate and controlled bass.
Additionally, larger woofers tend to have higher sensitivity, making them more efficient at producing low frequencies. With greater surface area, they require less physical excursion than smaller woofers to reach the same sound pressure level, which lowers distortion and generally results in cleaner bass compared to a small driver that needs significantly more excursion to achieve the same output. This also means that a larger woofer requires less power from the amplifier than a smaller one to achieve the same sound pressure level.
