  • Amp recommendations

    I have been following the CHT subs (specifically the 18" passives) for about a year and a half.

    I am curious to see what the amps folks are using to drive the passives. I know the standard is the Dayton amp, but thats not an option for me.

    I am wanting to purchase 2 CHT 18" passives in the coming months for a 21'6 x 13'6 x 8' (could be 9' ceilings) room. I am aware this is probably serious overkill, but I would rather purchase 2 and have the flexibility if I move into a bigger room that 2 subs would allow for. It also obviously allows me to do some serious damage to room nulls by moving things around. Plus, a wise man once told me "Its really easy to turn down the gain on a amp, its not always possible to turn it up" :D

    I am wanting to run each off a different channel of an amp to set myself up for Audyseey XT32 which EQ's each sub indpendent, hence not wanting the Dayton amp.

    I have heard mention of the QSC GX-5 amp, the Behringer EP-4000. I am REALLY curious if anyone is running them using a NON pro amp (like a Carver TFM-35 or others)

    I would recommend a Crown XLS 2000.

    It's light( Class D, 11 lbs)
    Powerful
    Nicer looking than the Behringers
    XLR and RCA connections
    No fan mod needed, very quite.
    Limiters and Crossovers built in.

    After a lot of research I'm going to use one to power my LMS-18" 5400.

      Unfortunately that amp will not work (and its 100 more than the others I mentioned). Craig (of Chase Home Theater) recommends an amp that can do 500 RMS @ 8 ohms (the Crown only does 325).

        EnderShadow - I am using the XLS-2500 with good results. It's 440 WPC into 8 ohms, and has plenty of headroom. It's about $200 more than the Dayton, but for your intentions, should fill the bill.

        I have also talked to one of the Techs at Dayton, and in his opinion, the QSC GX-5 is a solid choice - he far prefers it to the Behringer, and it's in your price range. I will likely get one of these and a Marathon 5050 to try with a pair of SS-18.1s (The QSC) and a pair of SS-18.2's (The Marathon).

        So - While I have no personal experience with the QSC, a tech from the company who makes the Dayton does like it.

          I will keep that in mind, but its a bit above what I was hoping to spend on an amp (and this is one time I dont want to go used :doh! 1:)

          I am hoping to be in the 400 or under range if possible. If not I might need to rethink getting 2 18's and maybe go with something smaller...

          That and I do have a question/suggestion on the passive 18's. Maybe on the legs set them up to be able to be spiked. Its something I will probably do once I get them.

              Yup, I see it. That kinda helps as thats the one I have my eye on currently, however I am still seriously interested in seeing if anyone is using a HT amp to drive these subs. I am debating a Sunfire Signature 450x5 (and thats the 8 ohm rating per channel), which would have enough juice for me to run my front 3 + those subs with ease.

              My ONLY concern with doing so is that many HT amps dont have gain controls so when the EQ starts up its going to be going full tilt on the sub lol.... That and if the AVR EQ wants to gain it lower than -12 it cant.

              Might have to warn neighbors if thats the case.

                Do you happen to know if anyone is using one of the Inuke Behringers with any of these yet? I see they have some interesting EQ options in them.


                Also curious how the 18" passives would stack up to 2 Outlaw LFM-1EX subs.

                Included is the floorplan. Please note there will be an opening in between the kitchen and living room.

                  I own the 18T with the Dayton amp as well as (2) LFM-1EX subs and as much as I like the Outlaw subs, the 18T is a big step up. I needed a little time to get use to the change from nearfield ported subs (under 3' from the LP) to farfield sealed subs (14' away). I really prefer the sealed sound in my 3000 cubic foot dedicated room

                  I have used the OmniMic to help blend the Outlaw subs in and continue to use them as end tables.

                    That was kinda what I was hoping to hear.

                    I also might have a line on a Carver amp to drive these bad boys...... And this amp has BALLS!!!!!!!!!!!

                    Carver PT 2400 750 wpc @ 8 ohms :woo:

                      I have the Carver PT 2400 beast. You will need Qty 2 - 20amp circuits to get that power. Sound of the amp is very neutral. Have fun.

                        I figured it might. Does it have 2 plugs? The manual only shows one (I know the TFM-75x has 2). For right now if I get that amp IT WILL BE CURRENT LIMITED. I plan to run it at under 1/4th power at max for right now (and will have it connected to my APC H15). I am in an apartment (overkill I know) and it will have to share current with all my other gear which includes a Carver AV705x amp.

                        When I get a house I plan to get 3 or 4 dedicated circuits for my HT.

                          Yes it has 2 plugs, It really is 2 mono amps in 1 chassis.

                            Gotcha. That will be interesting since my H15 only has 2 high current outlets and I would have 3 high current items........

                            The amp manual states it should get 2 dedicated circuits due to its power draw. Assuming I have the gain set decently low (since it has the power to blow these subs) would I be ok to run this amp off the same circuit as all my gear?

                              Sorry, not to thread crap but I would like to know a few things.

                              I am considering getting a 18.1 (1 for now depending on the costs) and was wondering why would i opt for getting the 18.1 without the amp (18.1P?)? Actually, it doesn't seem like you can do this, you have to order one with the Dayton.

                              Is it due to the dayton being a mono amp? Is it because at 8ohms, it puts out something less than than 400 watts when the driver has an RMS of 500 watts? I will be purchasing an audyssey xt32 capable receiver in the future, so I would like the ability to connect the two subs separately.

                              I was dead set on a rythmik FV15HP option but it seems like getting multiple 18.1 would be better on my wallet and at this point, not sure how important I want high SPL at < 20hz. I am sure anything at this point will be a step up from my BIC PL-200

                              EDIT: Reading further, the Dayton doesn't allow a lot of options for Eq'ing. Something that seems to be mentioned is the inuke for a better buy. Also, I must correct myself but the SS-18.1 is rated at 800 watts RMS rather than 500 as i previously stated. Considering the Dayton is only at 497 watts RMS (and lowere probably in terms of true output), it seems I would be really underpowering the driver with a dayton. Even a Crown XLS 2500 at 440 watts, QSC GX5 Power Amplifier at 500 watts, or an inuke at ??? watts. any comments on this.

                              Thanks for the help.
