What type of input connections are used on Spendor loudspeakers ?
All Spendor passive loudspeakers use gold binding posts, bi-wired or tri-wired where appropriate. Spendor professional monitors use 3 pin XLR sockets with gold connectors.
Who is the manufacturer of Spendor's drive units ?
All Spendor LF and MR drive units are designed and built at our factory for exclusive use in our loudspeakers, and HF units are made to our rigorous specification by leading specialists.
What does "pair matching" mean, and is it important ?
All the component parts of our products are methodically matched across the frequency band to within 0.5 dB before assembly, ensuring a perfectly stable stereo image at all frequencies.
A lot of other manufacturers use a thicker material for the cabinet, isn't this better ?
Not necessarily. This is often an attempt at economy by reducing the damping. We select top quality panels, which are then optimally damped and braced where neccessary. This not only reduces cabinet resonances, but more importantly reduces the energy storage within the panels which can "smear" the midband and destroy imagery.
Can Spendor loudspeakers be bi-wired, and if so what is the point ?
Yes. All Spendor loudspeakers are bi, or tri-wireable. This wiring method can give improved sound quality for the cost only of a second or third set of cables. This works by keeping the different return earth currents separate, reducing electrical intermodulation distortion. As the bass driver has the strongest current flow, three way models are best bi-wired by removing the lower links and leaving the midrange and tweeter on a common cable. Separating the midrange and tweeter cables will have less effect than just separating the bass driver as the intermodulation distortion is less apparent.
What cable should I use to connect up my Spendor loudspeakers ?
Unfortunately the answer to this question is not straight forward. It is true that cables can have an important effect on sound quality. Advice should be sought from your Spendor dealer, but trial and error is usually the best solution. To retain the correct frequency balance of the loudspeaker, cables should have a loop resistance of less than 0.4 ohms.
What stands should I use with my Spendor loudspeakers ?
There are many stands available from specialist manufacturers, and trial and error is still the best selection method. As a guide, the function of a stand is to place the loudspeaker at a suitable height, and to maintain that position as rigidly as possible, whilst exhibiting minimal self resonance. With this in mind, the height of the HF unit should be roughly level with your ears, and front to back rigidity should be paramount. Resonance control is best served by high mass stands, those that can be filled with sand being popular. The loudspeaker will ideally be supported by the stand at the four corners of it's base where the cabinet is most rigid, with coupling to the floor via spikes recommended (although other methods of floor coupling may be appropriate in some circumstances, such as some suspended floors, or in rooms that exhibit strong resonances).
What amplifiers or CD players do you recommend ?
Once again, there are so many to choose from, it would be impossible for us to audition all of them, and unfair to recommend any from those that we have. You should seek advice from your dealer, and take note of product reviews in the audio press as a guide. The overiding factor in choosing any piece of equipment is to set a budget to at least narrow the choices available to you.
Can I put Spendor loudspeakers in close proximity to my television ?
Yes. All Spendor loudspeakers benefit from reduced external field drive units. This has become essential within the professional market, with increasing use of high-tech VDU based mixing consoles, such as the Soundtracs Virtua.
What happens if my Spendor loudspeakers ever need repairing ?
All our domestic loudspeakers carry a full five year warranty against defective materials, however accidents do happen ("I went away for the weekend, and my son had a party……"). No problem. We continue to manufacture replacement parts for all of our products, where possible, even though most Spendor owners will never need them.
Just how loud is 100 watts ?
This subject is perhaps one of the least understood by many loudspeaker purchasers, mainly because nobody ever explains it to them ! "Loudness" is a function of power dissipated by the loudspeaker, and the sensitivity or efficiency, that is, how much of the power is produced as sound. It requires double the power input to produce 3 dB more sound output, this is true regardless of what level is being produced. Consequently an 89 dB/1w/1m loudspeaker driven at 50 watts will produce the same level of sound output as an 86dB loudspeaker at 100 watts, or an 83 dB loudspeaker at 200 watts and so on ! So why aren't all loudspeakers high sensitivity ? Well, increased sensitivity is a trade off against LF extension, and the skillful designer will produce a loudspeaker with the combination that bests suits his design objectives.
