Super rare and spectacular speakers from Cello. 

The Stradivari Grand Master Speakers consist of a line array design, capable of projecting into the largest of listening areas with even and full sound throughout.

Built with no less than 8 tweeters, 8 midrange drivers, and dual 12" woofers per speaker! 

They feature two sets of completelly separate crossovers with tri-wire capabilities, hence the use of two mono amps per side.

This allows the Grand Masters to produce SPL upwards of 127db!

Condition is good, grills are solid, all drivers work perfectly. 

They are finished in a warm medium wood veneer.

The 12" Woofers just came back from the consummate professionals at Millersound, where they received fresh surrounds and a clean bill of health. 

We can supply matching Cello amps if needed. 

Freight, shipping, and crating is a flat $1500 to the lower 48 states.

Please see our last photo or the linked manual below for full specifications:

Cello Audio Stradivari Grand Master Loudspeakers - Manual

Grand Masters
Like the concert grand piano, the Grand Master is the largest model.

Elegant in dimension, each Grand Master is a towering cabinet with eight tweeters, eight midranges, and two 12" woofers.

These drivers allow for a great quantity of air to be moved quickly, achieving not only very low distortion but a staggering 127-dB SPL peak capability.

Since no single driver is required to overwork, a completely effortless reproduction is evident on even the most demanding musical passages.

SkyFi Audio is a small startup business specializing in the purchase, reconditioning, and reselling of select high-end audio equipment. We only buy equipment the we admire and are passionate about. No mid-fi, no gimmicks, no junk.

Each piece of equipment is cosmetically restored and fully tested in our well-equipped lab by an engineer with 30+ years of experience in the HiFi world. If it does not meet or exceed the original manufactures specifications, it will not be sold. We are very selective about the equipment we purchase, focusing on mostly analog, high-build quality, American, and European built units.

Through our sister company which is an authorized dealer for McIntosh, Audio Research, Sonus Faber, ClearAudio, Pro-Ject Audio Systems, and Sony ES, we have access to OEM parts, service, and support. If you’re local and looking for new equipment from the above-mentioned manufacturers, please drop us a line as we can arrange both sales and professional installation in the tri-state area.


We do not accept or review any offers that do not go through the official Audiogon system. We have too many items for sale and it’s nearly impossible to keep track of offers outside of the official system. Please don’t message, email, or text any offers. 


We prefer working through PayPal which allows you to use a credit card, bank transfer, and their special financing to spread out payments over six months. We do not charge extra for any PayPal fees if you purchase the item at the asking price. You can also send us a personal check (which will need to clear before shipping), certified check, money order, or bank wire transfer. International clients without access to PayPal should use a bank wire transfer. 

If you’re picking up an item, we do not accept PayPal. You must pay in person with a certified check, bank check, or wire transfer. If you make a PayPal payment and are picking up the item, your PayPal payment will be returned. 


We accept trade-ins of equal or lesser value under certain conditions. Simply click here to submit your gear for full consideration. We will only consider high-end equipment from mainstream manufacturers such as McIntosh, Mark Levinson, Audio Research, Krell, etc. and will typically pass on displays, projectors, receivers, dated surround processors, and mid-fi equipment of any type. We will offer a fair value for your equipment, but keep in mind we’re running a business and will need to be able to resell the equipment at a profit after investing a great deal of time and resources in testing, certifying, repairing, cleaning, and packaging the incoming equipment. If you’re looking for top dollar, we suggest selling direct on your own.

SELL US YOUR GEAR (Working or Broken):

We’ll also purchase your used or broken gear and arrange pickup if you’re in our local market. Simply click here to submit your gear for full consideration.

SCHEDULING AN APPOINTMENT:                                                                                

We are currently operating from our shop inside our dedicated building in Glen Rock, NJ. You’re welcome to make an appointment if there’s a piece of equipment you’d like to see in operation before or after purchase. We have several well-equipped and dedicated listening areas, plus a dedicated listening studio with tons of equipment of all makes and models. We’re not a store, so please don’t make an appointment if you’re just curious as to how a speaker or piece of equipment sounds. In essence - no tire kickers please.

You can call or text 201-879-0000 with any questions or to schedule an appointment. We can also arrange to install, calibrate, and tune your newly purchased gear in your listening room if you’re local to our area. This is super useful when purchasing large speakers or heavy amplifiers. It’s also great for ensuring your new turntable is setup correctly in its final resting place.
