Hi,
I'm trying to offload several DIY audio parts and even a pair of full speakers. I will charge actual shipping/insurance costs to your destination based on your preferred shipping arrangement (coming from Aurora CO 80016). Here are the items I have for sale:
$1000 - DIY Aleph J in 5U Chassis
$1000 - DIY Bookshelf Speakers with 15W/8530k-00 ($220/ea retail) + Seas Millennium ($482/ea retail) + Jantzen Crossover
Free - Pair of planar magnetic tweeters of unknown manufacturer - will ship with first person to buy > $100 worth of gear from me
$110 - Pair SB Acoustics SB17NAC35-4 (1 impedance measurements never mounted + 1 BNIB)
$180 for 4 or $100 for 2 New Peerless HDS 830875 Midwoofers (1 taken out of cardboard to look at but never mounted or measured)
$180 for 4 or $100 for 2 used Seas ER19RN-TRD mid woofers (These were in surround sound speakers for about 2 years)
$80 for pair of GRS PT6825-8 8" planar mid/tweeter (new)
$70 for pair of GRS PT6816-8 8" narrow planar mid/tweeter
$80 for pair of Dayton RS52AN-8 2" Dome Midrange (new)
$2300 for all OR
$1500 for all except either the Aleph J or DIY bookshelf speakers
While there is a bit of ambiguity purchasing a DIY loudspeaker designed by me. All I can say is that these sound excellent. Except for overall output level, everyone who has listened to the bookshelf speakers prefers their sound over the pair of Kairos (Jeff Bagby design) I built previously. They image very well and don't require any EQ to my ears unless I use them in my office as desktop speakers. I've built lots of speakers from LX521, Troels "The Loudspeaker" and really find their sound signature second only to the LX521. "The Loudspeaker" was fun because it had no practical output limit in a domestic setting. Of course they are 5.5" drivers so best crossed over to subs if you want to play loud but without or for near field they sound fantastic. There is just something special about this pairing of great drivers. I've attached the final simulated response captured as a screenshot. I can provide design files in SoundEasy but can't launch the app anymore due to lack of support on modern computers. If I remember correctly I did end up padding the tweeter down a little more by ear but you can always manipulate L-pad to your liking.
Likewise the Aleph-J amp is in the DIY Audio Store deluxe 5U chassis and is a beast. I really like the sound of the amp but have been using Hypex plate amps for my recent builds so it's been sitting around. I've used it a bit in my home studio but it's really just too big (and runs too hot) for that space. I had a 300b amp running "The Loudspeaker" but changed to the Aleph-j in that application (I sold those speakers a while ago).
For references check out my eBay/Reverb rating (user jf4828 on both). I'm happy to do transactions through those platforms if you prefer but would have to charge a bit more to cover selling fees....
I'm happy to snap some more photos if needed; just let me know what you'd like to see 🙂
