Dog-proof? Meaning it won't sound like a dog or immune to being chewed by a dog?

 

[RonVinyl]

I am trying to make something that is dog-proof... I am looking for options. The WIBAQ is a good option as well. That said I am looking at a 6-8 week lead time on the Betsy-K IIRC.

Meaning something substantial so it wont topple over. I have a golden retriever with lots of energy. 99% of the time he is great. That 1% of the time could create some problems.

In that case the wall mount cornu horns are golden for your retriever. Nothing to knock over and out of reach.

Hanging speakers lower the WAF greatly.

My current plan is to build the WIBAQ, my brother has a pair of Betsy-K.
If I love them great, I will buy a pair of Betsy-K drivers and be done with it. If I have the itch to try something different I will build the SuperPensils.

Thanks for the suggestions, clearly this is a never ending trail to perfection.

I have listened to A12p in thr Superpensil and I was VERY impressed, even do impressed that I bought the A12p drivers. The demo was with low power set tube power. The a12p us truly one of the best FR speakers U heard so far (and I listened to several over the years). It will be a very interesting alternative to your b&ws.

If spatial imaging is important, the A7's will work better. Someone on another thread had Pensils w A12's but when tried A7's in simple foam core cabinet noticed imaging was best he had heard in years.

I built a founken with the el70(planet 10) and was a amazed by the sound and founkens look good(not that easy of build) Look over at bob brines he has some cabinet designs for some of the speakers you mentioned I built one for the 8" fostex using mdf and painted it sounds great.

Interesting, I will dig up that post and give it a read. Thanks!

The only issue with dropping to a smaller driver (in my setup) is the efficiency...

A7 - 85 dB SPL
A10 - 87 dB SPL
A12P - 92 dB SPL
Betsy-K - 95 dB SPL

I decided on the SuperPensil.
Drivers are ordered.

Any recommendations on products to use for PolyFill that can be found at lowes or HD?

 

[faithintruth]

Gorilla glue....be sure to dry fit all panels as this glue becomes quickly tacky and has a really short clamp time.

Any pro wood filler will do. They're available at Home Depot or others. Stay away from Home depot plywood as it's full of voids.

I was going to suggest Metronomes but you're aleady decided...

Just my two cents

 

[RonVinyl]

Does Lowes have better plywood than HD? I was planning on using Birch 8-ply min. 13-ply would be nice. We do have a local lumber store I will checkout.

I was also thinking about putting carpet padding on the interior walls of the SuperPensil, good idea?
