Post Re-Coned Vs Brand new. Advice needed

Hi there everyone.

Much to my girlfriends dismay, I plan on building a subwoofer to accompany my bookshelf speakers. I am aiming for a 12" driver in a sealed cabinet as to not take up much room. I am on a budget and would like to spend not much more than $200 on the driver, however, living in Australia hikes speaker component prices considerably. Thus I contacted my local speaker repair guy to see what he has. As it stands he has a 12" Subwoofer driver for $150 that he has re-coned himself. He seems to think is a pretty great driver and I trust him, he knows his stuff. Apparently the Fs is roughly 32Hz and the Xmax is 10mm. The closest brand new driver I can find is the Dayton Audio DCS305-4 12" Classic Subwoofer 4 Ohm which has a Fs of 24.2 Hz and an Xmax of 9.3. It would cost me $200 here in Australia.

- Which is the better option?
- Are there more specs I should ask for?
- Do re-coned speaker ever sound as good as new ones?
- who am I?
- Do I need to know the exact optimal cabinet volume if I am going for a sealed cabinet, or can I build a 1.5 cubic foot box and add/subtract stuffing to find right 'size'?
- How will i ever understand this stuff without studying audio engineering?

An answer to any of the above would be much appreciated Thank you

1st Step - ask for the t/s parameters for that rebuilt driver.

If he doesn't know what t/s parameters are, buy the Dayton driver .

A properly done recone is for all intents and purposes a new driver so it should perform the same and last just as long.

You need a drivers T/S specs to design the correct enclosure for it.

Sweet, thanks for the help. i didn't know what to ask for when I asked if he knew the optimal enclosure volume but he said he could do some measurements and find out for an extra $50. I thought this was pretty steep as those parameters are pretty important for using the driver properly. He also said I could save myself $50 and just build a 1.5 cubic foot enclosure as sealed subs have a big margin of error when it comes to enclosure size.

I am thinking I will go with the re-coned one as it will end up being the same price as a new possibly lower quality driver (once parameters are known) but I wont have to wait for shipping. I have zero patience enough trust in my speaker guy to give it a shot

LOL.

"Well, I don't know the rim size and width of this tire that you're looking to fit on your car, but I could measure it for you for an extra $50 on the cost of the tire..."

It literally takes only a few minutes to measure t/s params with the right equipment. Asking $50 for it is ridiculous IMO.

if he reconed it himself, he must now the type/brand of the driver.
with that you can find the thiele small specs on the net,if its a decent driver.
give him a call and report back here.

Hi Myleso, there are quite a few places in Australia that supply drivers. this guy you have found sounds dodgy. $50 for specs come on, I would pass on it. have a look at "lsk". he has lots of drivers.The Loudspeaker Kit

It might be worth seeing if you can get JBL car subs. The GTO1214 is a good driver for the price.

LSK is probably where I will end up buying the driver from. I have noticed that it is sometimes much cheaper to ship the part from Parts Express in the US though. Thanks for the tip though!

I went to see the driver in question and was a little disappointed by its looks. It seemed a little faded and quite old so I gave it a pass. I'm now looking at expanding my budget a little and going for the Dayton Audio RSS265HF-4 10" Reference HF Subwoofer. The reviews on Parts Express are awesome but so are the reviews from pretty much every driver on their site so I don't wont to just base it off that. Does anyone know much about this driver? I would want it in a sealed cabinet. The manufacture specs say 0.53 cf is optimal but I can see people are using it in much larger cabinets e.g. 1.5 cf. Whats a better size and how can i tell? maybe ill post another thread to sort this out.

Cheers!
