It's always my pleasure to meet Lansing Heritage members in person....Thanks, Joe. I hope you and your lovely wife had a nice time in SoCal, despite the typically awful holiday traffic.
I'm just sorry it took so long to get the kits for the 2245Hs...but they turned out nice, nonetheless.
Your craftsmanship on these cabinets is a work of art. The attention to detail is simply stunning.

I left work early yesterday to get these assembled. I am totally pleased! It was worth every minute and every penny, and I haven't even dialed in the crossovers yet. The 2245's are amazing, deep and tight bass.
Here are a few more pics:
Note the lack of grill velcro. I have neo magnets embedded in the baffle from behind. I was unsure if I should do this, because the magnets attract dust (and screwdrivers), but now I'm glad I did. The grill attachment is so easy. Turns out that I don't even need the grill guide pin, too bad I drilled it already. Otherwise the baffles would be completely clean.
And here is a final shot of the corner, to show how it looks finished. I love Baltic birch!
Looking very good. I'm sure you'll enjoy many hours with them!

Love the fresh recones. That + your craftsmanship makes those cabs stunning. How deep are those magnets how many and what is their size? I'd like to use the same grill mounting technique if I decide to build a second pair of 4344's finished to my taste.
Is the eq plugged into your chain? I'm experiencing quite a bit of boomyness from my 2235ers in the 80-300 range. If that eq is plugged in it seems you have a similar problem. I suspect the source of it to be from one or a combination of the following reasons:
1. Room response
2. New speaker surrounds
3. Inadequate internal damping
I can't do much about #1. #2 will take some time to figure out. #3 is the only hipothetical cause that can be worked with in my case. I 1" of sheep wool on the inside of the cabinets. Need to experiment a bit.
Other things to check.
4. LF too close to the floor. (LE14H, 136H/2231H, 2235H and 2245H didn't require boundary reinforcement while the 124H/2203H was a bit more forgiving)
5. Too much DCR in the LF filter inductor(s).
6. No fiberglass insulation. (Greg tunes his enclosures using fiberglass, if you don't use fiberglass you will need to re-tune and/or re-volume the enclosure accordingly.
Note that not using fiberglass isn't trivial, it changes the net effective volume of the enclosure and therefore the system tuning as well as driver loading.
Sounds like #6 is my problem. I'm not a fan of fiberglass but if it's a must...
Possibly.
Easy enough to check.
Greg invariably used 1" fiberglass on all surfaces but the baffle.
It is icky to work with... I preferred the tuflex in the Bozaks but it didn't seem to work so well in stock JBL enclosures.
Very nice J4K!! Those truly are a "Statement" speaker system!! Enjoy.
Always fun learning more.......
They are pretty big, 3/4" diameter x 3/8" thick N52. I took a guess at the pulling force I needed, used an online calculator to get and idea of the size, and then bought the cheapest size that was comparable. They are set almost all the way into the baffle/grill, about 1/16" from the face, covered only by a ply or two. Grind the point off of your forstner bit, and double check the depth stop before you drill! They are secured with epoxy, and if I ever do it again I will cut an opening for the air to escape when they are inserted.
The dust attraction is a real problem, it will form a faint shadow and it doesn't clean easily.
The EQ is not in the chain, the curve in the picture is left over from my old setup. I ran some pink noise through last night, and the response is pretty flat. I'm a bit surprised, even if the speakers are perfect I would have expected more room anomalies and inaccuracies in my cheapo RTA setup. Anyways I did locate a polarity problem, and there are a few small bumps and dips but nothing that seems significant compared to the problems I dealt with last time.Is the eq plugged into your chain?
