what’s the reasoning for this?

That's a fine way to look at things. To each their own, live and be happy! I'm not of the same mindset. That's not to say the folks here are not every bit as knowledgeable as you say. It's just how my brain is wired. I've spent a career working with people who are "professionals" in their trade...

Thanks for adding your thoughts, it took more than a few keystrokes to put all that down in writing! I agree with the tradeoff statement (I'm an engineer :p ). I don't dispute that all other things being equal an active crossover would be the better choice - but when you are modding a speaker...

I get that, and as I just posted to DanR I'm not against the concept of powered subs inside a speaker - I have a set of Definitive Technology towers that do it quite nicely. The difference in it being done from the factory, is they have already done the work of tuning the internal amp and the...

Good to know! I get the concept of the whole idea. I have an early set of Definitive Technology speakers with powered subs from when they were a new company and Sandy Grossman was designing them - they are AMAZING sounding speakers. I'd love to have a set of the Golden Ears that he worked on as...

This is where I am very skeptical, and wonder if you are assuming that the subwoofer amp is more powerful than the main stereo amp? What if it's the other way around...and by a large amount? I think I read in the specs for the crown amp that was mentioned it could put out 350W x 2 at 4 Ohms. My...

Thank you! I can appreciate what you are saying here, and it's much more in line with the question I originally asked - about crossovers. Talk more about that last sentence...what are you basing that on? Why would combining an active crossover with an arbitrary frequency range (not matched to...

So what you and the folks who are "liking" your statement appear to be saying is that statements which I clearly framed as personal concerns, are somehow being construed as "blanket incorrect" statements????? Seriously????!!!! The "blanket" covering is one sided and it's NOT from my side. You...

@ DanR, no, I never said any of what you are claiming. This group is unbelievable! You guys are a tough crowd. It's like you think I'm coming after you or something. If you read my comments, I NEVER jumped on any specific type of amp. I did ask questions of the one member who mentioned them to...

You are only proving my point here...As I have stated several times - using entry level equipment would mean the amp may not be powerful enough to fully drive the full range of the speaker and in those situations a mod like the one discussed here may give improvements. My entire statement is...

What specifically are you claiming is false? Please give me a link to a thread using the amps you are referring to and/or a link to the product information. The ONLY examples I have seen of this mod give the make and model of the amps being used and they are all Behringer or Crown "professional"...

The basis for the downgrade comment is that these mods are all using amps/crossovers intended for PA use - not critical or even in home listening. If you are using entry level equipment to begin with, then sure it might be an upgrade. But if you are using higher end/capable equipment begin with...

I’ve read the posts on the active bass conversions. I have 2 concerns with that: 1) for users who already have a capable amp with plenty of headroom - it’s a downgrade. 2) In a situation like mine where the crossover is damaged - it won’t work. The crossover is still needed to filter low...

Hi all, new member here. I purchased a set of used ReQuests from a vintage audio shop. They were purchased new by the previous owner who still had the original shipping boxes and they are serial numbers 6 and 7 which I thought was cool. I went to set them up and they both play music, but one...

Anyone done a mod like this for the ReQuest model? Only a single front firing woofer on each cabinet so just the amp should be all that’s needed. Manual says the factory crossover frequency is 180hz. Are the other models that much higher that you are setting it to 450?

New member, new to ML, New house... Recently moved into a new home where I finally have a room primarily for listening. It's not perfect, but better than anything I've had before. I plan to start tweaking the room with some treatment starting wit bass traps and going from there. Speakers: ML...

Hi audio enthusiasts! I’ve been a long time admirer of Martin Logan electrostats and finally bought a used pair of ReQuests about 2 years ago. Due to unexpected life changes they sat in the box until a few weeks ago. I noticed one of them sounds great and the other pretty muffled. I emailed ML...
