Hi mate

as mentioned before, my speakers are the version where the bass and mid woofers are the same HIF13 H driver.

This is why I thought of using this for the bass woofer replacement: SPH-135C

Yes it has a large coil which nicely cuts the bass down low. Why is that the dream of DIYer's? Because they're expensive coils?

No, I think, it's because it's what they call a 2-Way (Elipson 1302 being a real bookshelf 2-Way). Anyway you missed the point, the dream is having a speaker crossover-less or with a few components, being a 1. order (with only 1 crossover component) already difficult to find. But I digress... Now they call it a 2.5-Way. In this case is different. The woofer, that is the same for mid and bass duties (2 drivers connected in parallel each with 15 Ohms?? ), said woofer is in a bandpass enclosure working as an acoustic crossover with LF bandpass and midbass rolloff. If this makes sense to you. I would like to see the speakers and crossovers. Can you post yours? (or is it the same posted above?)

The speakers: It's like early versions started with 2x13cm drivers, then later 17cm + 13cm Mid, and later a 21cm Woofer + 13cm Mid.
  • 1303D: with 6 drivers 2xWoofers, 2xMidbass, 1 Mid dome and Tweeter
  • B 1303: with 3 drivers, 2x17cm + Tweeter.
  • 1303X: with 3 drivers, 1x17cm Woofer + 1x13cm Mid cone + Tweeter.

The tweeter used (with reference Siare, for previous 1303) was later replaced by a HD 12X9B25 Audax (??) this one being for sale now.

How is it going? New developments?! Regards.

Hi sorry for the delay I did not see this message.

Yes that is the tweeter it came with. I think my Seas h087's will sound better though no? I think they sound amazing compared to many tweeters. I hear a lot of detail in them.

Mine were definately the 2x13cm woofers + 1 tweeter originally.

The cross overs are un-touched.

I can't afford the new drivers yet but am really looking forward to restoring them!

Hi Aulday,

Interrested in your try to reproduce the same basse section, I would be pleased to know the bandpass volumes dimensions and the vent size, if possible.

Thanks,

Gro

Hi mate

Got loads going on personally so no time to get info right now. To make a stand alone sub I re-created the internal dimensions (minus the angled off corners at the front, my box is square looking from above so there is slightly more volume). Fitted one of these: Monacor Belgium N.V. S.A. - Dealer Area - SPH-135TC: HiFi Woofer with Twin Coil [ 101430 ]

And this port: MONACOR MBR-85 85MM BASS REFLEX TUBE SPEAKER PORT | eBay

Sounds great, very deep.

I made cross overs for the woofers with coils but can't remember the values, had to be pretty big though.

Hi Aulday,

Thanks for this answer.
Have fun with your ongoing projects.

The dimensions will be welcome when available, but I still can experiment a bit.

Cheers

Tom, don't know if you're still reading this thread but I have a pair of these speakers!
Brand is Spectrum built by The Radio People in Hong Kong. I bought them 2ndh off a friend (who lived in HK for several years) when he returned to Australia. They're still going strong. As others have said I believe they're based on the Elipson 1303. Ever seen the Hegeman horn? This one built by the Radio People.
retro vintage modern hi-fi: Lowther Hegerman Teak 1950-1951 Pair
regards Ian
