jof062 Posted December 27, 2012 Posted December 27, 2012 (edited) The base driver in one of my speakers seems to be saging a little and allthough it still seems to sound ok,Maybe a slow degregation in sound and i have not noticed? So went looking for a replacement driver that may be an impovment to the oem units and found someone else had used a SEAS H1288 with good results so just looking for opions here fellas before i order a pair (will be $200 delivered a pair) It crossovers at 150hz http://www.seas.no/index.php?option=com_content&view=article&id=115&Itemid=137 http://aarestrups.dk...s/NewWoofer.htm http://aarestrups.dk/Jamo.html Cheers Geoff Edited December 27, 2012 by jof062
SteveLuck Posted December 28, 2012 Posted December 28, 2012 Unless whoever your buying from has them in stock i'd look elswhere, I've had to cancel one order for Seas stuff from HAS Audio who just couldn't get me a delivery date and who is no longer trading from his website. The efficient Germans have given nothing but delays, Inteterchnik.de they have delivered two 10 inch Ro4y Seas subwoofers but not the matching passive radiators. I have to wait till mid January for those the order was placed weeks ago. Shop around prices and shipping cost seem to vary massively. A French site had the best deals on Seas stuff but i found their site after I'd placed my order with ze Germans. I wanted subs and matching radiators but at the size your looking for there's heaps of choice. I've got to say the best service I've had so far has been from parts-express they don't do Seas but a big choice on other drivers and almost same day shipping.
jof062 Posted December 28, 2012 Author Posted December 28, 2012 (edited) Found a place with stock Got all excited too when i found a 10% off gift for signing up but then realised i had to convert euros to aussi dollars :huh: Now $240 delivered. http://www.europe-audio.com/intro.asp Edited December 28, 2012 by jof062
jof062 Posted January 3, 2013 Author Posted January 3, 2013 (edited) Drivers are here and attempted to fit them this afternoon and have run into a small problem they don't fit as described in the the links above :angry: My own fault really as i should have removed the old divers and taken measurements myself before ordering instead of relying on internet blurb. Anyways the 7.7 and the D590 are different in the base driver and crossover, The 7.7s had a spacing ring that must have been an after thought (change of driver after the cabinets had been made perhaps). The D590 uses no such spacer and the driver has a different part number but still seems very light duty. So now i need to remove 12mm from the driver hole and 14mm from the recess with a router for the driver to sit flush...Best laid plans and all that! Will need new negative speaker plugs as well as the standard jobie uses two different sizes (Small and Large) and the Seas are both large. The crossover and terminal plate are also different the 590s have a larger terminal plate and the cross over looks a little different as well but will sus that further. Was going to add to the links above but having no joy with that so will just post it here and maybe it might save someone some grief one day. Edited January 3, 2013 by jof062
VanArn Posted January 3, 2013 Posted January 3, 2013 It might be better at this stage to have the original drivers repaired,rather than find further difficulties.Improvements require experience and measurements as part of the procedure,so merely swapping over to another woofer regardless of price as an indicator of supposed quality,would also entail crossover changes.Anyway take your time and rethink your approach.
jof062 Posted January 3, 2013 Author Posted January 3, 2013 (edited) Mmm ok...cheers Spose i could bolt them in without cutting anything with some hi density foam to fill the 2mm gap and the driver will still miss the bottom plate, Give them a rip i guess and see how they sound. If they come up winners all good and if not the old ones will still bolt in ok. Nothing ventured nothing gained! Edit: Maybe better to cut some MDF spacers, Got some 3mm in the shed. Foam job a bit agricultural. Edited January 3, 2013 by jof062
Aryan Posted October 21, 2020 Posted October 21, 2020 First of all the Speaker mentioned above from Seas does not have the same impedance ohms has 8 ohms does not have 4 so it will not fit from the start to that filter in Jamo D590, it is a big nonsense - the fit to the hole does not matter with the ohmic value and with the adaptation to the filter, at least if you put it at 4 ohms it was still something but even so the other Thiel characteristics and the speaker measurements don't fit .... it's an aberration what you proposed and did! The bass from Jamo D590 has 40 W and 4 ohms, otherwise no one talks about the speaker values that must be measured before adapting to a filter as well as the enclosure, the 3 frequency tunings must be brought to the same potential as "K" if not , Tolba comes out with arrows, not an acoustic enclosure and it will sound like a broken barrel Jamo D590 bass = 4 OHMI not 8 OHMI !!!!! https://europe-audio.com/Product.asp?mfr=Seas&part=H1288-08&Product_ID=5617&fbclid=IwAR0BpxAWZ6N_cV95EB8-48JrtrU6So5S_vf4_vjAJvfjzF9T6CdD2yTj-UU
gat474 Posted October 21, 2020 Posted October 21, 2020 Contact Aranmar acoustics in Melb, they are Seas dealers and might have old stock on hand. Worth a phone call at least.
Aryan Posted October 21, 2020 Posted October 21, 2020 I have all the components and that's why I was interested in what kind of replacement it could be, but in Australia I found only comments of all laughter, I was informed that not only Romanians are idiots, whoever told me this was right ! A great electronician by the way! I am not interested in another new speaker identical to the factory one, the original ones from Jamo D590 are some copies, lines if you want after SEAS, they have nothing to do with the Seas company at all, instead it looks like it but it doesn't rise! I wanted to see if there is anyone who successfully adapts a loudspeaker with power, with a higher wattage than the original one that has only 40 watts to know if I can reconstruct in DIY mode such speakers with filters with components that cost 1300 E, it seemed that we would read only aberrations here, first of all the world does not know the ohmic value of incionts, so I let myself be harmed, so I made sure that there are no other fools who read and can believe the nonsense of one who had he bought a speaker and thinks he changed it and did a good job, he also posted on the forum, great shame! Thanks anyway for the response and kindness ~ Regards from Romania !!!
