Jay / Danny,

Not intending to crap on this thread, but...given the challenges of a DIY'er to apply paint worthy of this speaker, have you thought about going all "Vandersteen" on this design, i.e. putting a couple of dowels in the rear corners, CNC'ing some nice hardwood caps for the tops and bottoms, and wrapping the speaker in fabric? I could see offering just enough fabric to staple the ends to the dowels, allowing for a twist or 2 to cover the staples and pull taught (the back would remain open for access to the drivers and crossovers). The caps would have holes for the dowels, grooves to seat the wings, and a narrow groove for the edge of the fabric to fit into. Depending on the hardwood used, a simple tung oil finish may be all that is necessary.

Just some Friday afternoon thoughts.

go  easy  on  yourself man.    doing  a  great  job.    Always  remember, lot's of  light  coats    using  a  spary bomb is  always   gong to  result in better finish.  Block sanding  between coats    is the  way  to go... over  and over..   Will eventually  result
 in    a  gorgeous  finish.

Hi there. I'm back, and here is the embarrassing story I have.
I got the replacement driver from Danny, got it wired up and it worked great. Soldered in the bypass caps and hooked up my stereomour from bottlehead and it sounded great. Not lots of headroom (3.5 watts).

So I tried the bottlehead battery powered quickie preamp into the Folsom 7297 chip amp. Sounded great, but before the song was over, popping, crackling and lots of intermittent fuzz started. I tried swapping everything I could and it was still there. No idea how I was going to fix the gear. Turns out it was the directv box on the shelf below it. Took too many days to figure that out.

Love the sound, even in my untreated room.
I was going to put grill cloth over the drivers but behind the baffle, just didn't fit.













Now I am looking for best treatments to make and install to improve my imaging.

Thanks for looking and when I get a better handle on the sound to give a little review, I will.
Ben

They look really good!

I find the wall behind them is really good with diffusion panels.  Has worked really well in two different rooms.

Hi everyone, I have a spike question.

Has anyone used parts express spikes for under servo h frame subs?  I have been testing placement for quite a while, and there's lots of vibration reaching up to the top of my super mini's.  I knew I would be needing spikes on this carpet, but i couldn't find weight ratings for the spikes on parts express.  There are Dayton Audio outriggers which I would certainly entertain, but wasn't sure the look was what I wanted.  I did want to keep cost down, but if the heavy subs with a topper on them needs a substantial spike, I don't know what it is.

I was hoping to stay under $100 for 8 spikes.

Thanks for any info you all have.

I noticed Hal was using isolation under the Mini to isolate from base. Maybe he will chime in.

Here is an alternative from Danny:

I use HVAC vibration blocks between the planar baffle and subs.

I had those spikes from Danny on my super v kit.  I was hoping to stay shorter. 

Thanks for the quick responses!

I don’t have spikes under the H-frames but I have Herbie’s Fat Dots between the monitor and H-Frame

Might wanna give a couple sheets of  Sorbathane a try too (betwen  Super Mini's and  Sub tops)
I've used it between  the  Encores and subs,  Otica MtM's  & subs and now a nice thick layer between my crossovers and sub tops on the  Super7's.

It also  will  totally stick your speakers in place
