Im selling four Allison One grill sections for $200 plus shipping. This is for all four as shown. Shipping continental US only or if overseas via Ebay Global Shipping. As you know these are fragile and crack easily if removed and installed frequently. Intact ones are rare. Three have no cracks. One has a crack that a prior owner attempted to repair using reinforced tape. I read you can cement them together using ABS cement. There are two brass Allison One badges. I can pack safely at no charge. Im in Greenville SC. Local pick up is fine.

Allison tweeter pulled from Model One, used in models One, Two, Three, Four and possibly others. These are originals from Model Ones. Check to verify you can use in your system. Most of these have pushed in caps, dents, scrapes etc. This tweeter are about as good as you will find. Image is the exact tweeter you will receive. It has been tested working. I have other Allison parts for sale. Mids and 10 professionally refoamed woofers. Also nice grill sections and cabinets/crossovers with original boxes will also be available.

These Allison 8 woofer grills were removed from an Allison 5 speaker cabinet. I havent repainted them - just cleaned them up a bit. They are the original black color and are perfect for any restoration job as there are no cracks or shipped edges.

Very rare Allison acoustics AL105 P Loudspeakers exceptional condition, beautiful Oak colour. These are a second pair of matched American Allison AL 105 P refurbished ( sequential numbers ) loudspeakers that I am selling. Please feel free to review great feedback from first pair sold last year. They play exceptional well with all tweeters and woofers working perfectly. 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, all good to go. 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. This is needed after re-foaming drivers to optimise sound performance. So perfect opportunity to buy as a investment before prices continue to increase, as they have done over last 10 years. Will be sent by UPS 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 Acoustics Allison Four Bookshelf Speaker (Single) Woodgrain Cabinet Speaker is in good condition considering it’s age, and sounds great when hooked up to my own receiver and tape deck. All settings governed by the control switch along the back are functional, and allow for you to change the depth and quality of sound being produced by the speaker. On the outside, this speaker appears to be in sound shape, but upon further examination, the woofer on the top face of the cabinet appears to have been partially blown. I determined this by tapping lightly with my finger around the circular cone, and heard one particular point where the pitch sounded off. My guess is that there is a damaged coil underneath the paper, but I am not a professional with speakers whatsoever. Regardless though, I am unable to hear any distortion in sound quality when listening to music through it. Aside from the issues with the woofer mentioned on top, there is a small point of damage seen along one of the metal grates on the side of speaker. One of the mesh covers appears to have a tear in the metal in the shape of an L, that blends in very seamlessly when the grate is attached to the cabinet. The tweeters underneath both grates appear to be in excellent condition as well. Other than what has been detailed thus far, the speaker is in great shape cosmetically, with only a few scratches focused sporadically around the top and bottom face of the wood cabinetry. See all pictures closely for details of condition, and specifications of the speaker. I specialize in shipping large electronics such as this, and can guarantee that every precaution will be taken to ensure safe delivery of your purchase.

Offered for your consideration is one (1) Allison Acoustics two-way crossover network removed from an MS200 speaker, U.S.-manufactured c.1990. It was used to divide a 4” mid/bass woofer from a 1” dome tweeter at 2.5kHz and has top quality materials in its construction. This crossover is from the first version MS200; later MS-200 used a smaller tweeter and cost-cutting spring-tab +/- terminals.So, please see my large photos and read the remaining description to decide if this outstanding dividing network is correct for your needs. This Allison crossover is in clean, excellent condition. The black plastic chassis has no cracks, chips, or scratches. It measures 4?” in diameter, extends 2½” into the cabinet, and features heavily wound copper inductors, quality resistors, and a large capacitor. Plus, the sturdy +/- binding post input terminals hold speaker cable very tightly and can also accommodate banana plugs, pins, etc. And, Ive divided the woofer and tweeter wires neatly into pairs for the new owners convenience. Overall, this crossover network is very nicely preserved! Seldom available, this crossover is a great find if you have broken an input terminal, etc. on one of your MS200’s. It’s also ready for action in your next speaker-building project; a center-channel to match your MS200’s comes to mind! As pictured and described, this splendid Allison two-way crossover network is offered at a competitive price.
