Using Carver TFM amps for passive subs.

Post by EndersShadow » Sat Jul 23, 2011 10:47 am

So here's the deal. I found a set of subs I want to purchase, but they are passives. Not a big deal, just need an amp to drive them.

That is where the problem is. The manufacture of the sub suggests the perfect number is something that does 1000 watts RMS and 2000 on short term peaks for the pair, or 500 watts RMS and 1000 per driver. I keep getting recommended to go with "pro-audio" amps like Behringer, Crown, ect, but personally want to stay within the Carver family if possible.

So here's the question: Whats the average going price for a TFM-45 as this seems to be the lowest model that would meet these criteria (bridged of course). I also see the TFM-75 is just about the only amp that I could run 2 of these subs off, but I have this feeling they are pretty rare and super expensive.

Also anyone have some suggestions for non-pro amps that would meet the above criteria?

Looking forward to hearing your guys thoughts since its kinda hard to find folks with lots of knowledge about Carver gear :D

These are them: http://www.chasehometheater.com/index.p ... Itemid=131

They sell them w/ a Dayton amp that can drive both of them, but the problem is that I want to EQ each sub independent (in the long term). With the Dayton amp they sell I would end up with both subs EQ'd as one.

Craigsub (owner of that company) is working on a plate amp, but doesnt have one finished yet.

I'd use the M1.0t

Post by treitz3 » Sat Jul 23, 2011 11:32 am

The best Carver amplifier I have used on a sub was a M1.0t. Please note that this was also paired with a Velodyne SMS-1 sub woofer management system. Seamless blending of frequencies from the mains to the sub and the rig to the room. Plenty of available balls that hit down to 20Hz faithfully at concert levels. The only other Carver amplifier(s) I would consider for sub duty would be the 9t or 7t mono block amplifiers but I have not had those in the rig.

This amp/sub setup was featured at the 2nd Carverfest with my rig that was [at the time] called "crackbaby". The folks that attended that year can attest to it's capabilities.

That does also look like a good option as well. Looks like I will have to keep my eyes out for them.

I would be eventually pairing this with Audyseey XT32 on either a future Marantz (since their highest model only has XT currently) or a Integra, or Onkyo.

Yup, I want to eventually get 4 "maybe" but want to get 2 to start w/ so I can put them on either side wall, or in the apartment I am in now, in either corner of my room.

Dont need to crank it, but want uniform sub coverage.

These would be just a "little" step up from my single PSW125 lol....

That's cool..... the M1.0 (MKII) is what I plan on using for my sub when I get to that point.

:shock:

You want to run a pair of 18" subs in an apartment? Did I get that right?

Even better. Absolutely no change in sonics whatsoever but when it comes to available power? She doesn't back down to a challenge. You just keep turning it up and up and up and up.

[Note: I have seen one report of a MKII that has gone belly up and it has been reported to me that a couple more beyond that have gone belly up as well. Not knocking, just informing]

Along the same lines of this thread --
I don't have a sub or need a sub in my TT system as the mains handle it.

Still, I have 3 channels going wasted there on my 400x5.
How could I make use of that wasted power on a passive sub? I see those subs in the photo are not too high, and look very hard core - 8)
