The Spendor Thread..

Just pulled the woofer biwire and left the mid/tweeter. Looks like the 3/4 tweeter on both are not working. Purely just listening though. Will pull them tomorrow to double check

Use an empty toilet paper roll as a stethoscope over the tweeter to isolate the sound. Your ear on one end and tweeter on the other.
 
Wonder what's the major differences between newer generations of Spendors (like D7) and older ones (like SP 1/2)?

From what I've gleaned on the web the older spendors, and now the classic series, are a bit warmer and more lush sounding. The D series is faster, tighter, with deeper bass and more extended treble. Now always a good thing with some tracks I'm learning. But a good recording sounds absolutely fabulous on the D7s.
 
Recommended Deer Creek Audio stands for Classic Speakers, they did a custom build for my SP1 speakers and are fillable too. Fabulous workmanship!

Seeking input on Spendor A5r... pursuant to a few somewhat recent changes, working from home a significant one, and moving my Creek Evo 100A into my home office, I am looking to upgrade the attached speakers. I am a bit smitten with a set of A5r on offer. Is anyone here in a position to comment on this model or offer any insight on the pairing with my Creek amp. I have not heard them, but here is what I can imagine: clear midrange, good detail and resolution, rhythmic and musical (fun), not fussy about placement, good bass for their size. There is some info online, but really not much compared to seemingly most other Spendor models. Also not filling me with confidence, is that the reviews i found conclude that they are great speakers but smack of some initial disappointment. Any experience?

Decided to scratch the Spendor itch, after having and loving ATC and IMF and curious to explore BBC-lineage speakers. Acquired a pair of SP1/2. They are phenomenal.

I had a question about veneer upkeep. They appear to be walnut veneered, but don't appear to be lacquered. The advice I received from Spendor was to maintain the finish as if it were lacquered. Does anyone know whether or not the SP1/2 in walnut has a lacquer finish?
 
I two picked up some SP1 /2 not long ago in really nice condition, amazingly rich midrange anyhow i think mine had a finish on them .. BUT none the less i did a slow pass with howards feed and wax and the outer appearance came alive so one way or another the oils found a way to make a difference so maybe not finished or maybe at the age the ifnish had small compromises .. it cleaned them up and made the grain pop .. i would expect similar results with most oils and finishes
 
Another question for SP1/2 owners - how to remove the front baffle? The screws are out, but it seems like it's held by something at the bottom.

These are SP1/2 - not SP1/2E, not R2, just SP1/2. They have a small wood strip across the bottom.

Or, do I access the crossover by removing the back instead.
 
did you remove the small strip of wood below the grilles where the spendor label is? normally that is what you take out before trying to get the grille out. That said there are 6 pairs of screws (12 total) in the front baffle ,
In the first picture you can see the strip of wood that is in place, in the second you see it after it has been removed.. i usually take a plastic card (one you dont mind if it might break) or a plastic putty knife go in from the cloth grille side 2 prongs hold it left and right slow easy pressure .. lift each side a little bit that way, and the strip should easily pop up with a couple back and forth ..

@michigannick thanks! That didn't even occur to me. Luckily I have a set of automotive trim tools. Turns out the SP1/2 strip is held on with velcro.

The crossovers are mounted to the back panel of the cabinets. Idk if it applies to Spendors but when it comes to Stirlings, part of the speaker voicing involves the panels. If they're removed, Stirling claims they must be shipped back to the factory for re-tuning.

It might be better to access the crossover by removing the midwoofer.

That's interesting - I've searched the Spendor mailing group but Derek has never mentioned that this applies to the SP1/2.

The only mention of this about Stirling LS3/6 I could find online is here (emphasis mine):

Given the absolute ban of opening the cabinet, I couldn't explore inside the speaker to take some pictures or remove the drivers. The reason is that the rear panel is tuned to the chassis and when you disassemble and reassemble it, the tuning would be compromise and the manufacturer has to intervene to "retune" the whole thing. We are dealing with a "Resonance Control" cabinet, which technique does not damp the vibrations but calibrate them in order to contribute to the amazing spatial reconstruction given by this loudspeaker. The target has been reached by using a 9 mm birch plywood multilayer and not a deaf MDF, so to enable the sound to "breath" through the six panels. A brave choice.

(1) The article only mentions a ban on removing the rear panel;

(2) The front panel on the SP1/2 is MDF and not plywood multilayer, unlike the Stirling LS3/6 apparently.

I wonder how much screw torque on the rear panel or on any plywood multilayer panel affects the panel tension / cabinet resonance ... But that would be asking Derek for some very proprietary information, I imagine.

Mr. Hughes is an independent consultant these days and Spendor has a different owner now. There shouldn't be any worries about violating intellectual property rights. I read a recent post on the Yahoo Spendor group where he described the core materials of the crossover transformer, something unique Spendor was doing at the time FWIU. I doubt he'd mind divulging the torque specs, assuming there are any. They might have simply adjusted the torque until a certain graph response was achieved.
