Welcome Fernando,

Just respond back here a couple of times and you'll be in good shape. You know, tell us how great we are are something like that

I am also interested in a pair of the triples subs.
This is my first post and I will add more to allow for pm.

What is the weight of one triple sub?
I have a couple of listening areas and am concerned about ease of moving them.

I don't have much painting experience or skill.
Some have had their units painted by commercial painters or car repair shops.
How much does that typically cost to have done?

mdl62 · « **Reply #307 on:** 31 Dec 2017, 01:21 am »

The 370 amp for these subs on the GR website has one version.
The Rythmik website has multiple versions, including one with balanced connections.
I think that the GR version may have some other features and upgrades also.
Can someone please elaborate on that?

What would be the widest size clamp that I would need for the triple sub for glueing?

mdl62 · « **Reply #309 on:** 31 Dec 2017, 01:28 am »

I have a pair of Magnepan MMGs and a pair of 1.7s.

How does one add in inline filter to limit the signal to the main speakers?

I believe there was a mention of that earlier in this thread for Maggies.
The result was that the Maggies required less power from unloading the lower frequencies.

Wel. I've never actually weighed one assembled but, you'r e looking at 90lbs per triple flat pack (shipping weight), then it's about 22lb / woofer , wire , and no-rez so le's say for sake of argument, 160lbs finished.
the modulars would be very similar even though they are 1.25" Medex as opposed to 1.5" MDF for the non-modular version

It really varies but I can tell you it is not "cheap". I'd say around $1300 is minimum and it can easily be MUCH more especially if you need to pay for asembly and prep.
Some of the House of Kolor paints we've used get pretty costly but man, they are cool

features of all should be very similar although (I'm not 100%% sure) I don't think the high level inputs are functional on the balanced version. One thing you have to specify is that the amps will be used in OB config... a shelving cirucit neds to be added before they ship them out to you.

18".... I like to have a minimum of 6, more is obviously better. Never too many clamps

Once yo u know the main amp input impedence, yo can determine the size of cap required to basically high pass them the signal you want. Use a high quality cap. If you don't want to build this your self,, I think has been known to make some nice inline units that will work for you.

If you order through Danny he will be sure Brian adds the appropriate boards and caps/resistors as necessary. If you order the amps directly from Rythmik you have to tell them what drivers you will be using in addition to open baffle. Any of the A370 versions work. your choice should be based on what works best with your system. I prefer the A370PEQ3 for my speakers but a client had me build his with the A370XLR2s.

In addition to what Jay has said, the filter goes between the preamp and power amp. If your preamp and power amp use balanced connections you will need to build a balanced version of the filter. The only difference is for balanced you will need two caps per channel. One for each hot wire.

Or, you can open up the amp and add the cap inline to the inputs, less cable and connectors. Some may prefer this ....

Going to start the glue-up of my modular 2x12 H-Frames tomorrow.

I am thinking about using Titebond II glue as before, but does someone have a better recommendation for adhesive? All I have locally are Lowes, Ace Hardware and a local hardware store. That limits selection a bit.

Let me know.
