SPL-4000 - Canadian Monsters take over the front room...

I came across this pair of speakers a month or so ago, made in Canada. At first, I thought they might be white van speakers, or haut-parleurs du camion blanc, as they might say in certain provinces. The "busy" sticker might suggest this, as it has a frequency response graph, the word "digital" twice, plus TMI (too much information) references to the features of the drivers and the cabinets. But there is also a 10 year warranty on them (long since expired), and the tweeters look very much like those I've seen in Alesis and Linn designs. After a little research, I found that these are quite rare and pretty well regarded speakers, so I forked over the cash for them. They look very similar to Paradigm speakers. Plus I'm a sucker for clear poly woofer cones.

All of the woofer foams were shot, I managed to get some suitable ones from Rick Cobb. The dust caps pulled off easily, so I was able to shim the voice coils. The crossovers are very simple, with just an inductor and a poly cap, no need to recap. I cleaned the cabinets up, one had paint spots on the top, I removed this with some goof-off and fine steel wool. They did have risers on the bottom of the cabinets, but the wood was soft from sitting on a damp floor, so I removed these.

I couldn't decide whether I liked the pictures with the camera flash, or without, so I uploaded both. Look at them, standing tall like a pair of CN Towers in the room (OK, I'll stop with the Canada references now). At 41 inches tall, they dwarf the AR94s next to them, these are not small speakers themselves, and remember, this is without the risers. They are actually more efficient than the AR94s, which in turn are more efficient than the KEF 104aBs that were sitting there before.

I think you need more pictures of them! (I kid, I kid.) But those look cool, like one line of B&Ws of that era.
 
They look rather like dB Plus speakers, which were also canadian and (at least the ones I've seen) had silver fronts with very similar labels complete with frequency response curves. The dB Plus speakers were quite appealing, despite the white van aesthetics.
 
Yeah, I would have written those off as white van without even looking twice too. Just wondering though: what made you look them up? More than likely most people would have scanned right by those. Good on you for researching them! It would be interesting to see some internal pics of the cabinetry and drivers in them (not asking to tear your speakers apart though. lol) I am interested to hear what you think of the sound too. What would you compare them to? Cheers. :)
 
SPL were Paisley Reasearch branded. They were made by API who also made Energy, Mirage, Image and bought over Paisley probably mostly to get Ian Paisley to work on their other lines. They then turned his brand into a line for more rack system oriented stores who wanted a high efficiency speaker. Probably much better engineered than most speakers of that style. Maybe early 90's IIRC.

Did Paisley eventually become db Plus, or maybe it was the other way around?
 
These speakers are very efficient, they make a lot of sound with not a lot of watts. One thing I noticed last night. I was listening to some Average White Band, and I kept hearing rhythm guitar fills from Onnie McIntyre that I never noticed before. Maybe it was because I was sitting right in front of the speaker, or maybe it's just these sound so good? Later on, I asked my wife if she was singing, as I was hearing the backing vocals from the other speaker, but sounding like they were coming from the kitchen. Maybe it's the recapped Pioneer SX-626 playing a part as well?

A friend of mine had a pair. Excellent rock speakers. Bass response is phenomenal. Decent mids and excellent highs. As you mentioned, they're very efficient. You're sure to annoy your neighbors with these big boys.
 
The marketing people went way overboard with these LOL...so overboard they probably scared potential buyers away. "Smooth" "Ultra" those are new ones to me. At least they're mirror imaged...try them with the tweeters on the inside instead of the outside, Some of API's speakers that were mirror imaged were intended to have tweeter to on the inside, such as the Energy 22.
 
Nice score. Bet they sound great !! JOHN

They do. And that's only with low power amps like the Pioneer SX-626 I'm using at the moment, or the NAD 3020s that I frequently run to "burn in" for my AK customers (I have one or two of my own as well). I have four MONSTER power amps waiting to be repaired/restored : an Onkyo M-504, a NAD 2200, an SAE 2400, and a Soundcraftsmen. If I ever hook any of these up to these SPL-4000s, they might put out a "disturbing the peace" complaint against me....

Paisley did R&D for a lot of API lines. Most notably Mirage.
However db+ was its own line as was SPL, Energy, Sound Dynamics, Athena, Image, Audio Pulse, Paisley Research, Logik, Mirage.
& a few more that escape me right now. All under the API umbrella.
API also assisted in Paradigm & PSB design & assembly in the early years. They all used some of the same parts, That's why ya'
get the API vibe from some of those guys. API... Canadian Icons! Untill the mighty Klipsch grab them up & started making everthing
in China. Def' not the same quality products that they made in the past.

Cheers!

Thanks for the additional info. The PSB link makes sense though neither company admitted it. I used to sell the PSB 30/40/50/70R series which was replaced with the 30/40/50 MKII series. We then picked up mirage and the 360/460/760 series looked VERY similar to the old PSB R series in terms of construction. I figured it was no coincidence but the sales reps for both companies had nothing to say about that.
 
Cool, great find! I would have thought they were White Van too, just like how I thought my DB Plus 440's would be WV. I think they were made by API, who bought DB Plus, Energy and a few others, so that would explain why they have the silver front baffle, and also a very similar plate on the front with all the specs, just like my DB Plus's.

And also, do they have the port on the back, or something? Because if they do, you might want to keep them farther away from the wall than that to avoid port noises.
 
Brought these out of retirement storage AKA the back of the front room. I needed some efficient speakers to play with the single ended tube power amp, plus the Dynaco preamp loaned to me by Andy @nj pheonix. Their 98dB for 2.83v efficiency make them really suited to this amp. I'm in the computer room down the hallway, and I can hear the music just fine.
