FS:12" Guitar Speakers and 12" Woofers - AUS
Have some new great quality 12 Inch Jaycar speakers for sale, specs including most thiele small parameters are further down and detailed pics are attachments.
I personally bought these from Jaycar years back and just don't have the chance to use them. So out they go! Kids came along, and no more time. Familliar story for most.
The Woofers were bought for a 3 way Hi-Fi speaker build, and go down to 25Hz easily, and the Guitar speakers were for a marshall quad box clone for a tube guitar amp project. Both are no longer stocked by Jaycar, so now vintage I guess Jaycar have a reputation for excellent quality speakers.
3x 12" HI-Fi Polycone rubber surround Woofers
4x 12" Guitar Speakers
2x 12" Steel Grille kits
All are in original boxes as new. Never been used.
Asking price for speakers is $50 each plus postage and Grilles are $10 each.
Located in Tasmania / Australia. The speakers weigh between 3.1 and 4kg each packed and are in 34x34x16cm boxes. Overseas postage is probably out of the question, sorry.
PM or post if you are interested or want to make an offer or deal. Buy enough speakers and I'll throw in the grilles for free!!
