Default My old open baffle speakers, UK-only

I either need to strip these down for parts or sell them on as I don't have space for spare speakers here.

I built these to find out if I liked open baffle sound at home or not. After MUCH tweaking I got a great sound from them - rich, detailed, pleasing to the ear and work perfectly in my tiny room. Fantastic bass too, just don't expect it to be evenly spread down to 20hz

They are 3-way using a 1" Wharfedale tweeter, 4" Audax poly cone mid with DIY phase plug, and 4 x 7" woofers (made for cheap subs). The bass is boosted via "T-bass" meaning you need a solid state amp with decent current delivery, or else the amp may shut down or not sound right when playing loud.

There are 6 drivers per side, the baffles in 18mm MDF, loads of caps and coils, plus two 100VA transformers. Binding posts are gold-plated Mundorf ones, very expensive! These speakers are potentially worth buying just for the parts, depending what projects you're looking to get done.

I'd like 100 for these. They're to be collected from my home in Sheffield, UK.

If nobody wants to buy these to finish nicely, develop or just enjoy then I'll unsolder all the parts and bin the baffles. That, however, would be a waste.

Listening may be an option but I'm about to replace them with my new speakers so I don't know how easily I can demo them after today!

Simon

Anyone like to make me an offer before I break for the 100+ worth of parts I could use?! I've already pinched some coils from them and will soon take them apart completely.

Just seems a shame to bin a set of speakers that are so musical.

Nope, still intact other than pinching a coil off each one. Easily restored to full working order at this point. I was thinking of grabbing the 20 binding posts for use on my amps but I'll leave them on if you fancy taking the speakers off my hands.

Hi again

Simon, keep the binding posts, it's fine.
Oh, and Pay Day is the 28th so it'll be after this date if that's
acceptable - let me know.
Collection no probs and I can pick your brains about the Alpha while I'm there !!

Any time's fine Andrew. The price was 100 but it's very much negotiable, I'd just like to get some of the money back and, ideally, to see the speakers enjoyed. I'll leave the binding posts on, the belong there if they're to be listened to.

Next weekend, for a week, I'm in France. It's better if you come after that so you can stop for a chat.

Hope this post makes sense, I am rather drunk!

Simon
