Acoustic Research AR-3a Midrange Drivers (2)

Description

Acoustic Research AR-3a Midrange Drivers
T
his offering is for a matched pair of
NEW OEM AR-3a
Midrange Drivers.
They will also work as AR-LST replacements.  This pair was manufactured to AR specifications in the early 1990’s by the Tonegen Company of Osaka, Japan.  Tonegen was well-known as a high-quality OEM loudspeaker supplier, and in their later years AR used Tonegen for all loudspeaker service replacements.  Their construction is identical to the original AR midranges.  Part number is: 1210010-1A.
I purchased this pair in 1995 as back-up midranges for my AR-3a’s which are front-wired, so these are set up for that application.  At that time, I temporarily mounted them in my 3a’s to make sure they properly worked and then returned them to their boxes for storage.  I just bench tested them with my iPhone-based signal generator and dB meter.  Their output is well-matched, and they reproduce frequencies from 200Hz up to 12kHz- well within their specified crossover range.  DCR for both units is about 3-ohms, confirming their applicability to AR’s 4-ohm speaker designs.  I will include the mounting gaskets.
The pair will be carefully packed and shipped via FedEx Home Delivery to USA addresses only.  Actual delivery charges will be determined by your location within the US.  Please review the images and use the eBay message system to contact me if you have any questions prior to purchase.  These are vintage new, working electronic components, offered as described and as-is.  As such, no returns can be accepted.
Thank you for looking!
