I want more bass…


Superb pair L’Instrument large horn speakers with two 12” woofers in each speaker.
So how to get more bass? My PassLabs XA25 was too little, my Luxman M900u was too sweet, of course these are not party or club speakers but my guests who are not audiophiles (you know the one’s who ask what are those? I say tubes…) let’s call them the sound bar set!

These speakers are rated down to 18Hz can anyone suggest the best value amp that can deliver bass to these speakers take control and make them move? 98dB sensitive by the way…

Give me some used cheap but real good amps to try please. Exposure? Class A. Not my weak knee’d Bouyrrang A50 300B 😉

Even my D240 MKII Audio Research seem not to push them deep and strong enough for the sound bar set. Can’t imagine I need a subwoofer…

I’ll connect a sub to this system and see what happens…

Thanks everyone for you comments ✅

@pokey77 indeed, its a crazy hybrid mess! Marantz AVR1509 used as a pre/digital source... sometimes fed by a Pioneer LX800SE for SACD CD Bluray.

Yesterday I did a few things

1. Got my subwoofer working again I’m not sure why there was no sound out before. Something to do with the AVR settings. 

2. Ran Audessy again across the whole system setting front horn speakers to large

3. Ran bass heavy music from Tidal and SACD

4. Made sure the ARC D240 MK II was connected to play the front horn speakers. It rated at Power output. 120 watts per channel into 8 ohms, 240 watts per channel into 4 ohms ; Power bandwidth. (-3dB points) 8Hz to 60kH. The speakers are rated at 98dB.

This has raised the level of bass in the system and room. It’s a three sided room. It’s enough for me as it reaches deep and has some good thump. I think it could do more. 

These speakers are not biwirable. Eventually I’ll get to swap out a better preamp. I do have an LS10SE that’s allocated in another system. This is a problem of two systems in one. A stereo music system and a movie system. Previously I ran these separately. Now in my living room where the horn speakers are located, I need a movie system. And same in my HT too. The issue is the same speakers are used for both systems. 

The only other power amp I have on hand at the moment is a Marantz 8077 HT amp. Plus I have a corresponding AV pre the 8805 that I could swap out for the 1509 packing as a pre. 
Alternatively, I’ll need to switch these to the LS10SE preamp or try my heavy duty PMC MB2SE speakers, may give a better result too.
