Nice clean tweeter and has clear undistorted sound

Very rare Allison acoustics AL105 P Loudspeakers exceptional condition, beautiful Oak colour. Beautiful sounding speakers with very little use from the legendary Allison Acoustics factory in USA. Probably the best around on the market at this time. As part of a recent service /refurbishment ( Summer 2022 ) the following work was carried out to bring the speakers up to the highest Allison standards. Driver speakers suspension foam seals renewedNew spiders installed and voice coil magnet seats cleaned and reset to maintain the high standards set by Allison acoustics.New tweeter grills.New carbon steel screws fitted throughout. Just completed 100 hours of running in time, the longer I play them the better they sound. Will be sent by 24 hour fully insured delivery in a secure box with bubble wrap and foam. But before I tell you about Allison I need to explain a little about bass cancellation. A room can be pretty effectively treated for mid and high frequencies because their shorter wavelengths rarely cause unsolvable phase problems but the really big problems are below 500Hz where the bass is. Bass is omnidirectional; it travels in all directions. Not only towards the listener, but also towards rear and side-walls. When this bass bounces off the walls and is reflected back towards the listener, it has travelled a longer distance than the directly radiated bass. In the best case (when the speaker is so close to the wall that the reflected wave is still more or less in step with the original sound) this muffles the sound, destroys timing, makes bass pitch less clear or makes the bass overall just a bit woolly. More often (when the distance to the walls is great enough to delay the reflected sound so much that it is effectively arriving half a wavelength later) it causes cancellation at certain frequencies, which more often than not results in large dips in the mid bass. You can probably imagine what happens if this problem is doubled if both rear and side-walls cause the same problem. At the same time there is the real possibility that one wall causes cancelling while the other wall does the opposite, which is to amplify the bass at certain other frequencies. The end result is a long shot from the wishful thinking that is the flat frequency curve. The theoretically best place for a bass speaker is smack in the corner. This way, all bass, both direct and reflected, is traveling the same distance and is always in phase. This is why we place subwoofers in corners. The bass is amplified acoustically and couples best with the room. Of course you can’t just shove any speaker in the corners of your room because the acoustical amplification will not only keep the bass in phase; it will also hugely colour the sound higher up the frequency spectrum. It works with subwoofers because they are filtered to cut off all frequencies above, say, 100Hz. This is so low that it is mostly below the room resonance and the result will be powerful full bass. Normal speakers also have to portray the midrange and high frequencies. These two are hugely compromised when a speaker is placed near a wall.In come the Allison speakers. They have been designed from the get-go to be placed in corners. Their frequency curve has been tailored just so that they sound neutral when they are placed in the corners of a room. This is not an entirely new idea but these days, in the current loudspeaker assortment, it is unique. Have you ever noticed that the amount of bass differs enormously depending on where you stand in the room? The cool thing about the Allison speakers is that the bass sounds perfect just about anywhere in the room.

Allison One speakers. One original second generation OEM 10 inch Woofer These are not original vintage but these were purchased from Allison Acoustics when they were still producing products. From what I hear at that point they were not the original owners and this woofer may vary from the original vintage driver. The surround needs to be replaced. The center dust cap is cracked Measures 3.6-3.7 ohms. The rear basket is intact.
